    Implications of passing by reference

    Ah, that makes sense! Thanks

    Did you see the echo'd results being displayed? Did you restart your webserver after making the changes to php.ini? Also, try the following. error_reporting(E_ALL); ini_set('display_startup_errors', 1); ini_set('display_errors', 1); xx

    Implications of passing by reference

    If getValue is given a path which doesn't exist, I can use the isset check to return null. I can also use the uncommitted $tmp =&$tmp[$key];. Why does this prevent an undefined index warning? public function getValue(string $path) { $path=explode('.', $path); $tmp=$this->config; foreach($path as $key) { //if(!isset($tmp[$key])) return null; //$tmp =$tmp[$key]; $tmp =&$tmp[$key]; } return $tmp; }

    Oh yeah, make sure you have errors enabled.

    help with charge formula

    I recommend adding the following: syslog(LOG_INFO,'$video_play_price: '.$video_play_price); syslog(LOG_INFO,'$charge: '.$charge); syslog(LOG_INFO,'$amout: '.$amout); $uploader_amount = $video_play_price - $charge; $uploader_amount = $amout - $charge; If you don't know how to use syslog, research it. If you don't want to (however, you should), do this: echo('$video_play_price: '.$video_play_price.PHP_EOL); echo('$charge: '.$charge.PHP_EOL); echo('$amout: '.$amout.PHP_EOL); $uploader_amount = $video_play_price - $charge; $uploader_amount = $amout - $charge; exit; Then, make sure the values are what you expected.

    Setting deep object properties

    I actually tried array_merge_recursive but found it did not meet my needs and ended up writing my own version. Looks like doing so was not needed and array_replace_recursive is the right solutions. Thanks!

    Setting deep object properties

    It's not the detection which I have an issue with but how to set them. Unlike arrays, I cannot just use $config->a->b->c->x=123 if a, b, or c is not set. Ah yeah, I do remember (now) that isset() unlike array_key_exists() will return false upon null. Thanks

    Setting deep object properties

    Thanks ginerjm. Good point, however, it is not my design (the objects are the json objects used to configure Highcharts) and realistically they will only be 3 or 4 deep max . Any recommendations on the best approach? Thanks

    Setting deep object properties

    I need to set a deep property if it is undefined or NULL such as shown below: function setProperty($value, stdClass $config, $p1, $p2, $p3, $p4) { if(!isset($config->$p1->$p2->$p3->$p4) || is_null($config->$p1->$p2->$p3->$p4)) { $config->$p1->$p2->$p3->$p4=$value; } } $config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123])); setProperty(321, $config, 'a','b','c','x'); setProperty(321, $config, 'a','b','c','y'); But I wish the function to work regardless of property depth and came up with the following. Recommendations for a cleaner way? Maybe I should be working with arrays and array_merge_recursive()? function setProperty($value, stdClass $config, array $properties) { $property=array_shift($properties); if(!count($properties)){ if(!isset($config->$property) || is_null($config->$property)) { $config->$property=$value; } } else { if(empty($config->$property) || !is_object($config->$property)) { $config->$property=new \stdClass(); } setProperty($value, $config->$property, $properties); } } $config=json_decode(json_encode(['a'=>['b'=>['c'=>['x'=>null, 'y'=>123]], 'x'=>123],'x'=>['x'=>123], 'x'=>123])); setProperty(321, $config, ['a','b','c','x']); setProperty(321, $config, ['a','b','c','y']);

    How to see threads I "like"

    @gizmola Yes! Thank you. This site said searches were not working thus I didn't try. Shame on me! @mac_gyver Thanks. After looking at this portion of my profile, there were no clues. Turns out I was wrong about "liking" it so I just did and now it shows up.
  11. A while back, I asked a question in PHP Coding Help, and requinix (I think) provided an unrelated comment that my API endpoints should not have an api version hardcoded in the URL (i.e. /1.0/some/endpoint), and gave a recommended solution. I recall liking the solution and planned on implementing it at a future date and am pretty sure I clicked "Liked". The future date is now, and I have been searching my past posts and haven't found it. Is it possible to view the posts which I have tagged as "Liked"? Thanks

    Implemented various HTTP methods

    Yes, makes sense. However, this means my whole approach with getData() and the switch(REQUEST_METHOD){case 'GET': case 'POST': case 'PUT':case 'DELETE':} logic is wrong, right? Instead I should have a getBody() method which doesn't have a switch statement and maybe a getMostlyUsedData() method. Ah, an eye opener! Just hit home that my ajax requests are passing application/x-www-form-urlencoded data and not application/json data. Should I not be doing so and instead pass a json string and content type application/json? This would make my obj2url JavaScript method obsolete and PHP wouldn't magically convert it to an array and assign it to the GET/POST supers, and instead I would need to json_decode() it server side. While this kind of makes sense for requests with a body, any data passed in the url would still need to be handled the original way, so I don't know... PUT /api/tickets.json/777577 HTTP/1.1 ... Accept: application/json, text/javascript, */*; q=0.01 ... Content-Type: application/x-www-form-urlencoded; charset=UTF-8 ... Accept-Encoding: gzip, deflate, br Accept-Language: en-US,en;q=0.9 ...

    Implemented various HTTP methods

    Thanks requinix, While GET requests don't have a body, I suspect that my get getData() method is not complete as it does not include any URL data for non-GET requests. Agree? Assuming so, if both the URL as well as the body defines a parameter, what should take precedent? I expected it would be more efficient to rely on PHP's low-level implementation for POST, and I guess I don't need more detailed explanation unless you feel you should give. I don't understand you point regarding "and anything else (eg, application/json) is up to you to read yourself." Please elaborate. Yes, PHP doesn't do anything with PUT requests or as far as I know DELETE requests, but there is no reason it can't be implemented as I am attempting to do, no?

    Implemented various HTTP methods

    Hi, Created the below script to deal with PUT and DELETE requests as well as different content types (i.e. json and xml). I realize there are existing libraries out there that are certainly better than what I created, but I did so just as much for the learning opportunity. Couple of questions. Thanks For GET and POST requests, is it best to use the PHP super globals $_GET and $_POST, or take a similar approach as I did for PUT and DELETE? When converting a stream to a string, is one of the following approaches better than the other? parse_str(file_get_contents($input), $contents); or if (!($stream = @fopen($input, 'r'))) { throw new ParserException('Unable to read request body', 500); } if (!is_resource($stream)) { throw new ParserException('Invalid stream', 500); } $str = ''; while (!feof($stream)) { $str .= fread($stream, 8192); } parse_str($str, $contents); I've never dealt with xml documents before. Any glaring issues with my implementation? While JavaScript, it is also related to PHP. My JavaScript obj2url() function converts an object to a url encoded string which can be parsed by PHP. I couldn't find existing code and had create it from scratch which makes me think I shouldn't be doing this. Any issues with it? Any other comments? <?php class ParserException extends \Exception{} class Parser { private $request; public function getData(bool $force=false) { if($this->request && !$force) return $this->request; switch(strtoupper($_SERVER['REQUEST_METHOD'])){ //Question. Is using PHP super globals $_GET and $_POST better/faster/etc for GET and POST requests than returning stream? case 'GET': $request=$_GET;break; case 'POST': $request=$_POST;break; case 'PUT': $request=$this->getStream();break; case 'DELETE': $request=$this->getStream();break; default: throw new ParserException("Unsupported HTTP method $_SERVER[REQUEST_METHOD]'", 500); } $this->request=$request; return $request; } public function returnData($data, int $code=null) { if($code) http_response_code($code); $type=$this->getBestSupportedMimeType(["application/json", "application/xml"]); header('Content-Type: '.$type); switch($type){ case "application/xml": $xml_data = new \SimpleXMLElement('<?xml version="1.0"?><data></data>'); $this->array_to_xml($data,$xml_data); echo($xml_data->asXML()); break; default: //case 'application/json':; echo json_encode($data); } exit; } private function getStream() { $input = substr(PHP_SAPI, 0, 3) === 'cgi'?'php://stdin':'php://input'; //Question. Why not just use: parse_str(file_get_contents($input), $contents); if (!($stream = @fopen($input, 'r'))) { throw new ParserException('Unable to read request body', 500); } if (!is_resource($stream)) { throw new ParserException('Invalid stream', 500); } $str = ''; while (!feof($stream)) { $str .= fread($stream, 8192); } parse_str($str, $contents); return $contents; } private function array_to_xml( $data, &$xml_data ) { foreach( $data as $key => $value ) { if( is_numeric($key) ){ $key = 'item'.$key; //dealing with <0/>..<n/> issues } if( is_array($value) ) { $subnode = $xml_data->addChild($key); $this->array_to_xml($value, $subnode); } else { $xml_data->addChild("$key",htmlspecialchars("$value")); } } } private function getBestSupportedMimeType($mimeTypes = null) { // Values will be stored in this array $AcceptTypes = []; $accept = strtolower(str_replace(' ', '', $_SERVER['HTTP_ACCEPT'])); $accept = explode(',', $accept); foreach ($accept as $a) { $q = 1; // the default quality is 1. // check if there is a different quality if (strpos($a, ';q=')) { // divide "mime/type;q=X" into two parts: "mime/type" i "X" list($a, $q) = explode(';q=', $a); } // mime-type $a is accepted with the quality $q // WARNING: $q == 0 means, that mime-type isn’t supported! $AcceptTypes[$a] = $q; } arsort($AcceptTypes); // if no parameter was passed, just return parsed data if (!$mimeTypes) return $AcceptTypes; //If supported mime-type exists, return it, else return null $mimeTypes = array_map('strtolower', (array)$mimeTypes); foreach ($AcceptTypes as $mime => $q) { if ($q && in_array($mime, $mimeTypes)) return $mime; } return null; } } error_reporting(E_ALL); ini_set('display_startup_errors', 1); ini_set("log_errors", 1); ini_set('display_errors', 1); $parser=new Parser(); try{ if(isset($_SERVER['HTTP_X_REQUESTED_WITH']) && $_SERVER['HTTP_X_REQUESTED_WITH']==='XMLHttpRequest') { $data=$parser->getData(); //application manipulates data as appropriate $parser->returnData($data); } else { echo getHtml(); } } catch(ParserException $e) { $parser->returnData(['error'=>$e->getMessage()], $e->getCode()); } function getHtml(){ return <<<EOT <!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8"> <title>API Tester</title> </head> <body> <div> <div id='output'></div> </div> <script> SHOWN BELOW TO IMPROVE READABILITY </script> </body> </html> EOT; } Below JS was moved out of the PHP file to improve readabity. function obj2url(params, key) { //Standalone replacement for jQuery's $.param() if(!key && Array.isArray(params)) { throw "obj2url cannot accept an array"; } var parts=[]; if(!key) key=''; if(typeof params === 'object' && params != null) { if(Array.isArray(params)) { for (var i = 0; i < params.length; i++) { if(typeof params[i] === 'object' && params[i] != null) { var subnode=obj2url(params[i], key===''?[]:key+'['+i+']'); parts.push(subnode); } else { parts.push(encodeURIComponent((key===''?[]:key+'[]'))+'='+encodeURIComponent(params[i])); } } } else { for (var i in params) { if(typeof params[i] === 'object' && params[i] != null) { var subnode=obj2url(params[i], key===''?i:key+'['+i+']'); parts.push(subnode); } else { parts.push(encodeURIComponent((key===''?i:key+'['+i+']'))+'='+encodeURIComponent(params[i])); } } } } else { throw "obj2url cannot accept a string"; } return parts.join('&'); } function ajax(stack) { if(stack.length===0) return; var request=stack.shift(); var data=obj2url(request.data); var url=request.method==='GET' ?request.url+'?'+data :request.url; var xhr = new XMLHttpRequest(); xhr.open(request.method, url, true); if(request.method!=='GET') { xhr.setRequestHeader("Content-Type", "application/x-www-form-urlencoded"); } xhr.setRequestHeader("X-Requested-With", "XMLHttpRequest"); if(request.responseType==='xml') { xhr.responseType = 'document'; xhr.overrideMimeType('text/xml'); xhr.setRequestHeader('Accept', 'application/xml'); } else { xhr.responseType = request.responseType; xhr.setRequestHeader('Accept', 'application/json'); } xhr.onreadystatechange = function() { if (this.readyState === XMLHttpRequest.DONE && this.status === 200) { var responseString = request.responseType==='xml' ?(new XMLSerializer()).serializeToString(xhr.responseXML): //or use xhr.response?
