本文实例讲述了php基于curl重写file_get_contents函数。分享给大家供大家参考,具体如下:
file_get_contents在连接不上的时候会提示Connection refused,有时候会带来不便;另外,curl的性能比file_get_contents高,所以用curl重写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; }
希望本文所述对大家PHP程序设计有所帮助。
