I'm using cURL to submit a form on another webpage and have ran into a weird phenomenon:
When I use
print_r($fields) to print out the post fields BEFORE I pass the array to cURL request and submit it, the form is submitted twice. When I remove that line from the script, the double submission disappears.
Why is printing the array causing a double submission?
//set POST variables $fields = array(); $fields['input-name'] = 'input-value'; print_r($fields); //causes double submission //open connection $url = 'http://blah.com/blah/blah'; $request = curl_init($url); //send post data curl_setopt($request, CURLOPT_POST, true); curl_setopt($request, CURLOPT_POSTFIELDS, $fields); // output the response curl_setopt($request, CURLOPT_RETURNTRANSFER, true); echo curl_exec($request);
