How to localize remote images in php

This article mainly introduces how to localize remote images in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.

The code is as follows:

<?php 
//站点根目录 
$cfg_basedir = dirname(__FILE__); 
//停建目录属性 
$cfg_dir_purview =&#39;0755&#39;; 
 /*Get请求远程内容函数*/ 
 $cookie_file = dirname(__FILE__).&#39;/cookie.txt&#39;; //COOKIE存放地址 
  function pget($url,$ref=false,$head=false){ 
  $curl = curl_init(); // 启动一个CURL会话 
  curl_setopt($curl, CURLOPT_URL, $url); // 要访问的地址       
  curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0); // 对认证证书来源的检查 
  curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 1); // 从证书中检查SSL加密算法是否存在 
  curl_setopt($curl, CURLOPT_USERAGENT, $_SERVER[&#39;HTTP_USER_AGENT&#39;]); // 模拟用户使用的浏览器 
  curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1); // 使用自动跳转 
  if($ref){ curl_setopt($curl, CURLOPT_REFERER, $ref);//带来的Referer 
  }else{ 
  curl_setopt($curl, CURLOPT_AUTOREFERER, 1); // 自动设置Referer 
  } 
  curl_setopt($curl, CURLOPT_HTTPGET, 1); // 发送一个常规的Post请求 
  curl_setopt($curl, CURLOPT_COOKIEJAR, $GLOBALS[&#39;cookie_file&#39;]); // 存放Cookie信息的文件名称 
  curl_setopt($curl, CURLOPT_COOKIEFILE,$GLOBALS [&#39;cookie_file&#39;]); // 读取上面所储存的Cookie信息 
  curl_setopt($curl, CURLOPT_TIMEOUT, 30); // 设置超时限制防止死循环 
  curl_setopt($curl, CURLOPT_HEADER, 0); // 显示返回的Header区域内容 
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1); // 获取的信息以文件流的形式返回 
  $tmpInfo = curl_exec($curl); // 执行操作 
  if (curl_errno($curl)) { 
 echo &#39;Errno&#39;.curl_error($curl); 
  } 
   if($head){ $data[&#39;head&#39;]=curl_getinfo($curl);} 
  curl_close($curl); // 关键CURL会话 
  $data[&#39;data&#39;]=$tmpInfo; 
  return $data; // 返回数据 
}
