Curl Request Append Response

Hello,

I am trying to do multiple curl requests and get the response for each one output to the screen.

I have wrote the following code, but only appear to be getting the last response when outputting $result.

What am i doing wrong? Is there a way to wait for each curl request to be completed before appending to $result so I can see them all?

Thanks very much

if (isset($_POST['submit'])) {
	$result = array();
	foreach ($textAr as $line) {
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
		curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
		$result[] = curl_exec ($ch);
	}
	curl_close ($ch);

	echo "<pre>";
	print_r($result);
	echo "</pre>";

}

Hi,

It returns a string like the following:

string(506) " status error error The domain xxx.co.uk already exists in our database. This may occur if there is a pending Order for xxx.co.uk in our database under your account or any other account."

I would like to collate all these return strings for each of the curl request (could be 10+) and return them as an alert/echo at the end of them all.

if (isset($_POST['submit'])) {

	$result = array();

	foreach ($textAr as $line) {
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
		curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
		$result = curl_exec ($ch);
		curl_close ($ch);
		var_dump($result);
		
	}

	// i would like all of the strings to be compiled into one for returning to the screen
	// but it seems like it only gets the last one instead of them all, even if i try string appending.
	// is there a way to wait until one is completed before the next?

}

Thank you for your help.

The first blob of code you posted was putting those results into an array and looks fine, but I can't help but notice that the request being made inside the loop is going to be the same every time. Shouldn't it be using $line somewhere?

Hi @requinix

Apologies i removed that URL bit to simplify it. The $line is passed into the url of the curl call so each is unique.

When using the below code and calling 3 curl requests for example; it only gets the last string response even if i try to append.

I cannot figure out whats going on!

if (isset($_POST['submit'])) {

	$result = array();

	foreach ($textAr as $line) {
		
		$url = "https://xxx.com/api/domains/meh.xml?auth-userid=xxx&domain-name={$line}";

		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
		curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
		$result = curl_exec ($ch);
        // $result[] = curl_exec ($ch);
		curl_close ($ch);
		print_r($result);
		
	}

    // print_r($result);

}

xxx1.com
xxx2.com

Array ( [0] => [1] => status error error The domain xxx2.com already exists in our database. This may occur if there is a pending Order for xxx2.com in our database under your account or any other account.)

As you can see, its only getting the result from the last one for some reason.

$line: www.xxx2.com $textAr: ["www.xxx1.com\r","www.xxx2.com"] Array ( [0] => [1] => status error error The domain xxx2.com already exists in our database. This may occur if there is a pending Order for xxx2.com in our database under your account or any other account. You may search for this domain within your control panel.)

 


	$result = array();
	
	foreach ($textAr as $line) {
				
		$url = "https://example.com/api/domains/blah.xml?domain-name={$line}";
		
		$ch = curl_init();
		curl_setopt($ch, CURLOPT_URL, $url);
		curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
		curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
		curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
		curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
		$result[] = curl_exec ($ch);
		curl_close ($ch);	
		
	}
	
	printf('$line: %s'.PHP_EOL, $line);
	printf('$textAr: %s'.PHP_EOL, json_encode($textAr)); 
	print_r($result);

I meant something like the following:

if (isset($_POST['submit'])) {

    printf('$textAr: %s'.PHP_EOL, json_encode($textAr)); 

    $result = array();
    
    foreach ($textAr as $line) {
                
        $url = "https://example.com/api/domains/blah.xml?domain-name={$line}";
        
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $url);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true );
        curl_setopt($ch, CURLOPT_ENCODING, "gzip,deflate");
        printf('$line: %s'.PHP_EOL, $line);
        $r = curl_exec ($ch);
        print_r($r);
        $result[] = $r;
        curl_close ($ch);    
        
    }
    
    print_r($result);

}

$textAr: ["www.google.com\r","www.yahoo.com"]
$line: www.google.com
$line: www.yahoo.com status error error Domain yahoo.com already registered
Array ( [0] => [1] => status error error Domain yahoo.com already registered )

Its like the second request blanks out the first. If i do three requests, i only ever get the last one.

$textAr: ["www.google.com\r","www.yahoo.com\r","www.bbc.com"]
$line: www.google.com
$line: www.yahoo.com
$line: www.bbc.com status error error Domain bbc.com already registered
Array ( [0] => [1] => [2] => status error error Domain bbc.com already registered )

Okay, $textAr includes URLs for www.google.com\r and www.yahoo.com.  Do you really want the \r with Google?

Then I see $line: www.google.com being echoed, but don't see the results being echoed.  Replace print_r with var_dump as it likely is returning NULL.

Then I see $line: www.yahoo.com followed by the error message.  I would have expected a line break but not a big deal.

Then I see the $results array with the first element being empty and the second being the error response.

Isn't this what you were expecting?  Consider changing $result[] = $r; to $result[$line] = $r; to make it more clear.

I was hoping for something like this, as each of these are already registered.

Quote

Array ( [www.google.com ] => status error error Domain google.com already registered [www.bbc.com ] => status error error Domain bbc.com already registered [www.sky.com] => status error error Domain sky.com already registered )

However, only get the last response

Quote

$textAr: ["www.google.com\r","www.bbc.com\r","www.sky.com"]
$line: google.com
$line: bbc.com
$line: sky.com status error error Domain sky.com already registered
Array ( [www.google.com ] => [www.bbc.com ] => [www.sky.com] => status error error Domain sky.com already registered )

You are correct, some nulls are coming back but i don't understand why there would be no response message with them.

$textAr: ["www.google.com\r","www.bbc.com\r","www.sky.com"]
$line: google.com bool(false)
$line: bbc.com bool(false)
$line: sky.com string(203) " status error error Domain sky.com already registered "
array(3) { ["www.google.com "]=> bool(false) ["www.bbc.com "]=> bool(false) ["www.sky.com"]=> string(203) " status error error Domain sky.com already registered " }
