php实现的Curl封装类Curl.class.php用法实例分析

本文实例讲述了php实现的Curl封装类Curl.class.php用法。分享给大家供大家参考。具体如下：

<?php//curl类class Curl{ function Curl(){  return true; } function execute($method, $url, $fields='', $userAgent='', $httpHeaders='', $username='', $password=''){  $ch = Curl::create();  if(false === $ch){   return false;  }  if(is_string($url) && strlen($url)){   $ret = curl_setopt($ch, CURLOPT_URL, $url);  }else{   return false;  }  //是否显示头部信息  curl_setopt($ch, CURLOPT_HEADER, false);  //  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);  if($username != ''){   curl_setopt($ch, CURLOPT_USERPWD, $username . ':' . $password);  }  $method = strtolower($method);  if('post' == $method){   curl_setopt($ch, CURLOPT_POST, true);   if(is_array($fields)){    $sets = array();    foreach ($fields AS $key => $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用法：

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

POST用法：

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

希望本文所述对大家的php程序设计有所帮助。
