PHP下载远程文件到本地存储的方法
本文实例讲述了PHP下载远程文件到本地存储的方法。分享给大家供大家参考。具体实现方法如下：
<?php
functionGrabImage($url,$filename=""){
if($url=="")returnfalse;
if($filename==""){
$ext=strrchr($url,".");
if($ext!=".gif"&&$ext!=".jpg")returnfalse;
$filename=date("dMYHis").$ext;
}
ob_start();
readfile($url);
$img=ob_get_contents();
ob_end_clean();
$size=strlen($img);
$fp2=@fopen($filename,"a");
fwrite($fp2,$img);
fclose($fp2);
return$filename;
}
functiongethttpimage($url){
if(!empty($url)){
$filename=uniqid().strrchr($url,".");
echo$filename;
$get_file=@file_get_contents($url);
if($get_file){
$fp=@fopen($filename,"w");
@fwrite($fp,$get_file);
@fclose($fp);
}
return$imgUrl;
}else{
returnfalse;
}
}
//$img=GrabImage("https://www.nhooo.com/images/logo.gif","");
$img=gethttpimage("https://www.nhooo.com/images/logo.gif","");
if($img)echo'<pre><imgsrc="'.$img.'"></pre>';
elseecho"false";
?>
