How to switch from POST to GET in PHP CURL

Question

I have tried switching from a previous Post request to a Get request. Which assumes its a Get but eventually does a post.

I tried the following in PHP :

curl_setopt($curl_handle, CURLOPT_POSTFIELDS, null); curl_setopt($curl_handle, CURLOPT_POST, FALSE); curl_setopt($curl_handle, CURLOPT_HTTPGET, TRUE); 

What am I missing?

Additional information: I already have a connection that's setup to do a POST request. That completes successfully but later on when I try to reuse the connection and switch back to GET using the setopts above it still ends up doing a POST internally with incomplete POST headers. The problem is it believes its doing a GET but ends up putting a POST header without the content-length parameter and the connection fails witha 411 ERROR.

Make sure that you're putting your query string at the end of your URL when doing a GET request.

$qry_str = "?x=10&y=20"; $ch = curl_init();  // Set query data here with the URL curl_setopt($ch, CURLOPT_URL, 'http://example.com/test.php' . $qry_str);   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3); $content = trim(curl_exec($ch)); curl_close($ch); print $content; 

With a POST you pass the data via the CURLOPT_POSTFIELDS option instead of passing it in the CURLOPT__URL.

$qry_str = "x=10&y=20"; curl_setopt($ch, CURLOPT_URL, 'http://example.com/test.php');   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_TIMEOUT, 3);  // Set request method to POST curl_setopt($ch, CURLOPT_POST, 1);  // Set query data here with CURLOPT_POSTFIELDS curl_setopt($ch, CURLOPT_POSTFIELDS, $qry_str);  $content = trim(curl_exec($ch)); curl_close($ch); print $content; 

Note from the curl_setopt() docs for CURLOPT_HTTPGET (emphasis added):

[Set CURLOPT_HTTPGET equal to] TRUE to reset the HTTP request method to GET.
Since GET is the default, this is only necessary if the request method has been changed.
