CURL and php

[Anon]

I have setup a system to make https posts to authorize.net for cc processing. It works great the problem I am having is that I have no way of assigning the result of the curl_exec() to a variable, right now I have to create a tmp file write the output to it then read the tmp file back in so I can parse the data sent back from the curl_exec(). My question is, Is there a way to assign this result into a varibale instaed of writing it to a file?

Here is the code I am using right now:
//Setup curl outfile
$fp = fopen($outfile, "w");
//initiate curl
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_FILE, $fp);
curl_exec ($ch);
curl_close ($ch);
fclose($fp);

//read in results
$temp = file($outfile);
$temp = implode("", $temp);
$data = explode(",", $temp);
for ($i=1;$i<=count($data);$i++) {
print "Code ". $i ." = ". $data[$i]."<br>";
}
unlink($outfile);

Thanks!

I figured it out and in case anyone is looking for the answer:
//Start ouput buffering
ob_start();
//initiate curl
$ch = curl_init();
curl_setopt ($ch, CURLOPT_URL, $url);
curl_exec ($ch);
curl_close ($ch);
//Assign the contents of the buffer to a variable
$temp = ob_get_contents();
//Shut off buffering
ob_end_clean();

$data = explode(",", $temp);
for ($i=1;$i<=count($data);$i++) {
print "Code ". $i ." = ". $data[$i]."<br>";
}

What is ob_start()?
I have a problem just like yours, and since sockets is no option for me, I have to make this one work.
I have to make a "normal" html submit with 3 variables from inside a script, and then read the returned xml into a new variable.

REading your follow-up message, it appears that you have done more work than necessary.

In the above script, having set CURL_RETURNTRANSFER to a non-zero value, you should just be able to use

$result = curl_exec($ch);

to place the output into the variable $result.

I am trying this, but it does not work.

curl_setopt($c, CURLOPT_POST, 1);
curl_setopt($c, CURLOPT_POSTVARS, $post_string);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
$string = curl_exec($c);
curl_close($c);

It sends the received file to output immediately.

I'm running PHP 4.0.4pl1 with libcurl 7.7 (SSL 0.9.6).

I just tried this, and it did not work either. The output apparently doesn't go into the buffer, it goes directly out. I am on PHP 4.0.4pl1 with libcurl 7.7.

Here is my full working function, in case it helps you any 🙂

function execute_requests($server, $path, $qstring, $username, $password) {

/* Set up cURL with curl_init.  $ch is for Curl Handle. */
$ch = curl_init();

/* Set username/password for request */
curl_setopt($ch, CURLOPT_USERPWD, "$username" . ":$password");

/* Set the type of request to POST */
curl_setopt($ch, CURLOPT_POST, 1);

/* Suppress header in cURL's output */
curl_setopt($ch, CURLOPT_HEADER, 0);

/* Make curl return the results to a variable instead of STDOUT */
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);

/* Set maximum time for cURL request */
curl_setopt($ch, CURLOPT_TIMEOUT, 5);

/* Construct request */
$requestedurl = "$server" . "/$path";

/* Set URL for request */
curl_setopt($ch, CURLOPT_URL, "$requestedurl");

/* Set query string for post request */
curl_setopt($ch, CURLOPT_POSTFIELDS, "$qstring");

/* Execute request */
$result = curl_exec($ch);

if(curl_error($ch)) {
	echo "Error retrieving <b>$requestedurl </b>";
	exit;
}                                           

curl_close ($ch);

return $result;

}

I am trying to do the same sort of thing, but for some reason CURLOPT_RETURNTRANSFER keeps failing and I get nothing.

Any suggestions?
