use php to parse json data posted from another php file

Should not this ?

$posts = array('data'=>$pCon);curl_setopt ($ch, CURLOPT_POSTFIELDS, $posts);

even the example in doc show that

from doc

The full data to post in a HTTP "POST" operation. To post a file, prepend a filename with @ and use the full path. This can either be passed as a urlencoded string like 'para1=val1&para2=val2&...' or as an array with the field name as key and field data as value. If value is an array, the Content-Type header will be set to multipart/form-data. As of PHP 5.2.0, files thats passed to this option with the @ prefix must be in array form to work.

your existing way should work too,

is it possible that $pCon contains some urlencoded values such as =, ? ?

$posts = array('data'=>$pCon);curl_setopt ($ch, CURLOPT_POSTFIELDS, $posts);

this worked.(the person who answered this question deleted the post so i couldnt catch his name, so thankx)

edit:there still was a small error every quote (") was changed to (\") i had a very hard time correcting this so now i am not sending data in json directly but first base64 encode it and when the page receives it , it base64 decodes it. now this workds flawlessly...thankyou all...
