Quick CURL question

[lonewulf]

Just a quick question while I consider writing this... will the following cURL work?

curl_setopt($ch, CURLOPT_POSTFIELDS, "$sidVAR={$sid[$i2]}&$cvar={$cid[$i2]}&$sVAR={$aVAR}"); 

Obviously missing code, just that CURLOPT_POSTFIELDS has me wondering if I can use variables like that.

It will work, sure. However, why do you want to construct a string like this anyway, sometimes using curly braces, sometimes not and not caring about proper url-encoded values?

Cannot remember exactly but you could choke it on the "&" s, if it happens then expand them to &

Get some reliable debug and error reporting going on otherwise cURL turns into a voodoo-ish blackbox in no time.

Just pass an associtive array for the post fields and be done with it, urlencoding and query-string building for free!

<?php
curl_setopt($ch, CURLOPT_POSTFIELDS, array($sidVAR => $sid[$i2], $cvar => $cid[$i2], $sVAR => $aVAR));
?>

Note that using an array for CURLOPT_POSTFIELDS will send the data as multipart/form-data which may or may not be a problem for your script. If you need it to be the more usual application/x-www-form-urlencoded then you can use:

curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(array(...)));
