PHP rewrites the file_get_contents function example based on curl

The example in this article describes how PHP rewrites the file_get_contents function based on curl. Share it with everyone for your reference, the details are as follows:

file_get_contents will prompt Connection refused when the connection cannot be reached, which sometimes causes inconvenience; in addition, the performance of curl is higher than file_get_contents, so use curl to rewrite file_get_contents

function _file_get_contents($s) { $ret = ""; $ch = curl_init($s); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FRESH_CONNECT, true); curl_setopt($ch, CURLOPT_TIMEOUT, 0); $buffer = curl_exec($ch); curl_close($ch); if ($buffer === false || empty($buffer)) { $ret = ""; } else { $ret = $buffer; } return $ret; }

Hope What this article describes will be helpful to everyone in PHP programming.
