update record not working

Hello Forum Admins,

I am PHP developer. and i am using zoho crm api ,and I am trying to update the record.

$curl_handle = curl_init();

curl_setopt( $curl_handle, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 5.1; rv:1.7.3) Gecko/20041001 Firefox/0.10.1" );

curl_setopt($curl_handle,CURLOPT_URL,$url);

curl_setopt($curl_handle,CURLOPT_CONNECTTIMEOUT,5);

curl_setopt($curl_handle,CURLOPT_RETURNTRANSFER,true);

curl_setopt($curl_handle,CURLOPT_FRESH_CONNECT,true);//No caching

curl_setopt($curl_handle,CURLOPT_FOLLOWLOCATION,true);

curl_setopt($curl_handle,CURLOPT_MAXREDIRS,1);

$buffer = curl_exec($curl_handle);

curl_close($curl_handle);

echo $buffer;

$url variable holds proper details...because when i copy paste $url contents in browsers address bar and hit enter, it shows me "record updated successfully" message, that means there is no problem with $url,

I tried many CURL variations but nothing worked it keep returning "false" can u please show me some standard php examples or find whats wrong i m doing ???

I have spent 3 days solving this problem....i posted this in few forums too but didnt find working answer.

Please help
