Example: $string = array(0 => "ABCDEFGHIJKLMN.."); // test with a string > 20000 length .. curl_setopt($s, CURLOPT_POST, true); curl_setopt($s, CURLOPT_POSTFIELDS, $string ); ... then on other side the server recive: "ABCDEFABCDEFABCD.." cuting the string in 16K size and repeated any times to complete the original size. Test the same code with PHP5 and this bug is not present. Test script: --------------- $string = array(0 => "ABCDEFGHIJKLMN.."); // test with a string > 20000 length .. curl_setopt($s, CURLOPT_POST, true); curl_setopt($s, CURLOPT_POSTFIELDS, $string ); ... then on other side the server recive: "ABCDEFABCDEFABCD.." ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=75597&edit=1
