how to post variables to file like jquery ajax but with php -

i'm working on project have include third party application in our system. application transmitts parameters php file using jquery ajax when calling index.php. exact function looks this:

$.ajax( {     type : "post",     cache : false,     crossdomain : false,     async : true,     url : "/somwhere/somefile.php",     data : "msg=37120&hello=true&usrid=1"     )}; 

i'm not experienced ajax @ far can see in end parameters "msg=37120&hello=true&usrid=1" postet on somefile.php. want post variables directly onto somefile.php using php instead of js/ajax.

after researches found following solution send post data directly somefile.php:

$url = "/somwhere/somefile.php";  $ch = curl_init( $url ); curl_setopt( $ch, curlopt_post, 1); curl_setopt( $ch, curlopt_postfields, "msg=37120&hello=true&usrid=1");  $response = curl_exec( $ch ); 

unfortunately not working @ all. no data arrives when i'm executing code block. i've no idea i'm doing wrong. can tell me whats mistake here? or there better way how this?

edit: sorry -- posted get, below code post.

this code use works well:

$cookie="cookie.txt"; $useragent="mozilla/4.0 (compatible; msie 6.0; windows nt 5.1; sv1; .net clr 2.0.50727; .net clr 3.0.04506.30)";  $data=array(   "field1" => 'data1',   "field2" => 'data2',   "submit" => 'true' );      $cr = curl_init($url);     curl_setopt($cr, curlopt_returntransfer, true);       // returned value string (dont put screen)     curl_setopt($cr, curlopt_useragent, $useragent);      // spoof user-agent browser user on (and accessing php $     curl_setopt($cr, curlopt_cookiejar, $cookie);         // use cookie.txt storing cookies     curl_setopt($cr, curlopt_cookiefile, $cookie);        // use cookie.txt storing cookies     curl_setopt($cr, curlopt_post, true);                 // tell curl posting data     curl_setopt($cr, curlopt_postfields, $data);          // post data in array above     $output = curl_exec($cr);
