The definition and use of Curl encapsulation class in PHP

This article mainly introduces the definition and use of the Curl encapsulation class in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

The details are as follows:

 $val){ $sets[] = $key . '=' . urlencode($val); } $fields = implode('&',$sets); } curl_setopt($ch, CURLOPT_POSTFIELDS, $fields); }else if('put' == $method){ curl_setopt($ch, CURLOPT_PUT, true); } //curl_setopt($ch, CURLOPT_PROGRESS, true); //curl_setopt($ch, CURLOPT_VERBOSE, true); //curl_setopt($ch, CURLOPT_MUTE, false); curl_setopt($ch, CURLOPT_TIMEOUT, 10);//设置curl超时秒数 if(strlen($userAgent)){ curl_setopt($ch, CURLOPT_USERAGENT, $userAgent); } if(is_array($httpHeaders)){ curl_setopt($ch, CURLOPT_HTTPHEADER, $httpHeaders); } $ret = curl_exec($ch); if(curl_errno($ch)){ curl_close($ch); return array(curl_error($ch), curl_errno($ch)); }else{ curl_close($ch); if(!is_string($ret) || !strlen($ret)){ return false; } return $ret; } } function post($url, $fields, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){ $ret = Curl::execute('POST', $url, $fields, $userAgent, $httpHeaders, $username, $password); if(false === $ret){ return false; } if(is_array($ret)){ return false; } return $ret; } function get($url, $userAgent = '', $httpHeaders = '', $username = '', $password = ''){ $ret = Curl::execute('GET', $url, '', $userAgent, $httpHeaders, $username, $password); if(false === $ret){ return false; } if(is_array($ret)){ return false; } return $ret; } function create(){ $ch = null; if(!function_exists('curl_init')){ return false; } $ch = curl_init(); if(!is_resource($ch)){ return false; } return $ch; } } ?>

GET usage:

$curl = new Curl(); $curl->get('http://www.XXX.com/');

POST usage:

$curl = new Curl(); $curl->get('http://www.XXX.com/', 'p=1&time=0');
