Hi Phreaks, I hope you've all made it through the weekend with sound body and mind. The following 2 methods have been working together harmoniously for quite a while: <?php public function action($action, $table, $where = [], $rule = "") { if(count($where) === 3) { $operators = array('=', '<', '>', '<=', '<='); $field = $where[0]; $operator = $where[1]; $value = $where[2]; if(in_array($operator, $operators)) { if($rule == "") { $sql = "{$action} FROM {$table} WHERE {$field} {$operator} ?"; } else { $sql = "{$action} FROM {$table} WHERE {$field} {$operator} ? {$rule}"; } if(!$this->query($sql, array($value))->error()) { return $this; } } return false; } public function get($table, $where = [], $rule = "", $column = "*") { return $this->action("SELECT {$column}", $table, $where, $rule); } My original belief was that it was easily extensible. I'm now to the point I'm trying to do that and receiving behaviour that I don't understand. If the action() method becomes thus -> <?php public function action($action, $table, $where = [], $rule = "") { if(count($where) === 3) { $operators = array('=', '<', '>', '<=', '<='); $field = $where[0]; $operator = $where[1]; $value = $where[2]; if(in_array($operator, $operators)) { if($rule == "") { $sql = "{$action} FROM {$table} WHERE {$field} {$operator} ?"; } else { $sql = "{$action} FROM {$table} WHERE {$field} {$operator} ? {$rule}"; } if(!$this->query($sql, array($value))->error()) { return $this; } } } else { $sql = "{$action} FROM {$table}"; echo "this <br>"; return $this; } echo "false <br>"; return false; } with the added else{} statement to handle queries without WHERE conditions, and call it with just the $table parameter -> <?php public function get() { // $table = "posts"; $table = "categories"; $field = "*"; $query = $this->_db->get($table); // print_r($query); var_dump($query); } //normally, using conditions, it would look like this: $query = $this->_db->get($table, array($field, "=", $value); It returns: which we can see is picking up my else{} statement as it should but is returning this empty object. Could someone explain this to me? thank you

I have my data array which i converted to json by splitting the keys using for each loop.

Keeping in mind the following conditions: 1.If all the keys in the objects are 0 then the entire object will be removed (easy part). 2.If a key in the object has any value other than 0 , the object should not be removed and the key with "0" value should also be there. i've tried splitting value and using conditions to check for 0 or null values but the problem with that is it removes all keys that have 0 values thus failing condition 2 for the code. $vars = $data; $count = ""; $finalArray = array(); foreach ($vars as $keys => $values) { foreach ($values as $k => $v) { foreach ($v as $ke => $ve) { if ($keys == "table6") { $count = (array)$v; foreach ($count as $ck => $cv) { if ($cv != "0") { $flag = true; break; } } if($flag == false) { array_push($finalArray, $count); } } } } print_r($finalArray); die(); I expeced the output to contain the objects with key value pairs that does not contain 0 value but everything prints here.

Q: Should instancing an object be held off until needed - or - instanced early and held in memory until (it may/or may not) be called? Here is an example of the type situation where an custom error reporting class is instanced only when some test has failed. The error reporting is for authorized users running an application from protected sub sections(RESTish solution). /* * check form input and $_FILES upload * if test fails, instance errorwrapper::factory object and call errorReport method * testfilesize function, compares file size limit, set pass1 to true on success * testfiletype function, compares file to allowed MIME types, set pass2 to true on success * svalidate returns array $filteres, sanitized input on success, error message(s) on fail * param boolean $pass[1,2], set initial test condition * param int MAX_FILE_SIZE, constant defines max file size allowed. */ $pass1 = false; $pass2 = false; if(isset($_FILES)) { $ftype = $_FILES['img_file']['type']; $fsize = $_FILES['img_file']['size']; testfilesize($pass1,MAX_FILE_SIZE,$fsize); testfiletype($pass2,$ftype); } if($pass1 == false) { $erparams=array('cat'=>3,'src'=>"addform_control",'ref'=>"addform",'fault'=>"over file size limit"); $errObj=errorwrapper::factory($erparams); $errObj->errorReport(); exit(); } elseif ($pass2 == false) { $erparams=array('cat'=>3,'src'=>"addform_control",'ref'=>"addform",'fault'=>"illegal file type"); $errObj=errorwrapper::factory($erparams); $errObj->errorReport(); exit(); } /* * process form input, all fields checked before returning filteres * could report multiple errors, mode sets level of sanitization. */ $filteres = svalidate($_POST,$mode=1); if($filteres['exit']==1) { foreach($filteres['err'] as $err) { $mes .= $err."\n"; } $erparams=array('cat'=>2,'src'=>"addfo",'ref'=>"list_viewer",'fault'=>$mes); $errObj=errorwrapper::factory($erparams); $errObj->errorReport(); exit(); } else { //continue processing here, error checking over } In this case, the object $errObj is only instanced on a failed condition. However, $errObj could be instantiated before the conditional test and only calls the method when there is a failed condition. It seems like "six to one half dozen" but these applications are large and complex, so I'm looking to squeeze out any worthwhile optimization. Thanks for considering the question.

My code; $sql = "SELECT SUM(IF(`submitdate` IS NULL , 1 , 0 )) as 'Survey Started But Not Completed' FROM `survey_$surveyid`"; $statement = $dbh->prepare($sql); $statement->execute(); $result = $statement->fetch(PDO::FETCH_OBJ); //pass that data to an object Is returning; stdClass Object ( [Survey Started But Not Completed] => )  I need to set this to a vaule that I can actually print out on the screen... Like a "0" for example. At the moment it is just a NULL. How do I do this?? These don't work; $result = 0; $result = array(['Survey Started But Not Completed'] => "0");

I think I'm starting to wrap my mind around how to work with OOP - Objects and Arrays I have starting a small test php file that I'm doing testing on. Here's my main file <?php require('includes/Connect.MySQL.Class.php'); ?> <?php require('includes/TopicFileClass.php'); ?> <?php $data = array(); // New instance/modifier of class MemberTopic $topic = new MemberTopic($data); // Retrieve topics from mysqli database $topic = $topic->retrieve_record(); //print_r($topic); ?> <!DOCTYPE HTML> <html> <head> <meta charset="utf-8"> <title>Object Oriented Programming</title> </head> <?php ?> <body> <?php foreach ($topic as $key=>$record) { // Loop through the Array to pull out the objects(records)?> <h1><?php echo $record->blog_name; // Display the Title of the Blog ?></h1> <p><?php echo $record->content; // Display the Content of the Blog ?></p> <?php } // Closes the foreach loop ?> </body> </html> An here is where I retrieve my data <?php require_once ("Connect.MySQL.Class.php"); class MemberTopic extends ConnectMySQLClass { protected $threads = array(); protected function main_record() { $database = parent::connect(); //Connects to the mysqli Database $query = "SELECT * FROM pages ORDER by id"; $result = $database->query($query); while ($page = $result->fetch_array(MYSQLI_ASSOC)) { $this->threads[] = (object) $page; } /* free result set */ $result->free(); //print_r($this->threads); return $this->threads; } public function retrieve_record() { //return $records = $this->assign_topic_record(); return $this->main_record(); } } My questions is there a way to make it so I have each object tied to a user name instead of a number? I tried doing $this->threads[$page['username']] = (object) $page; which only worked partially for it skip a few records(objects). If there isn't a way of doing it, it's no big deal for this has simplified my code a lot and makes it so much easier following what the code is doing. Thanks John
