## curl重写php file_get_contents > 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 复制代码 ~~~ 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 $ret; } ~~~ ~~~ <?php function curl($url, $ifpost = 0, $datafields = '', $cookiefile = '', $v = false) { $header = array("Connection: Keep-Alive","Accept: text/html, application/xhtml+xml, */*", "Pragma: no-cache", "Accept-Language: zh-Hans-CN,zh-Hans;q=0.8,en-US;q=0.5,en;q=0.3","User-Agent: Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)"); $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_HEADER, $v); curl_setopt($ch, CURLOPT_HTTPHEADER, $header); $ifpost && curl_setopt($ch, CURLOPT_POST, $ifpost); $ifpost && curl_setopt($ch, CURLOPT_POSTFIELDS, $datafields); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_ENCODING, 'gzip,deflate'); $cookiefile && curl_setopt($ch, CURLOPT_COOKIEFILE, $cookiefile); $cookiefile && curl_setopt($ch, CURLOPT_COOKIEJAR, $cookiefile); $r = curl_exec($ch); curl_close($ch); return $r; } ~~~
