Read raw post data, useful for grabbing XML from Flash XmlSocket.

/ Published in: PHP

Often PHP can't interpret POST data because it is not form-encoded. This is typical when the post data is XML from API's like Flash's XmlSocket. You can use the following methods to read the POST data directly.

/**
     Using php://input
     -----------------
     Version: 4.3+
     
     Reading [php://input][1] is the preferred method since PHP 4.3.
     
     The Content-Type header of the posted content must _NOT_ be 
     application/x-www.form-urlencoded or multipart/form-data.
     
     For XML you can use the Content-Type: text/xml.

// Make sure the user is posting
    if ( $_SERVER['REQUEST_METHOD'] === 'POST' )
    {
        // Read the input from stdin
        $postText = trim(file_get_contents('php://input'));
    }
  
    /**
     Using $HTTP_RAW_POST_DATA
     -------------------------
     Version 3.0+
     
     __Note__: Reading php://input is preferred.
     
     
     As with php://input, the Content-Type header of the 
     posted content must _NOT_ be application/x-www.form-urlencoded or
     multipart/form-data.     
     
     PHP 4.1+
     ~~~~~~~~
     You can also enable [always-populate-raw-post-data][1] in the php.ini to
     have the value always populated reguardless of Content-Type. However
     since this requires config changes it is less portable.
     
      [1]: http://us2.php.net/manual/en/ini.core.php#ini.always-populate-raw-post-data
    */
    $postText = $GLOBALS['HTTP_RAW_POST_DATA'];
