php下保存远程图片到本地的函数

Posted 2020-06-12

<?php
header("content-type:text/html;charset=utf-8");
function GrabImage($url,$filename="") {  
if($url=="") return false;  
 
if($filename=="") {  
$ext=strrchr($url,".");  
###指定远程下载图片的后缀，当然可以加以拓展
if($ext!=".gif" && $ext!=".jpg" && $ext!=".png") return false;  
$filename=date("YmdHis").$ext;  
}  
//www.bcty365.com 
ob_start();  
readfile($url);  
$img = ob_get_contents();  
ob_end_clean();  
$size = strlen($img);  
 
$fp2[email protected]fopen($filename, "a");  
fwrite($fp2,$img);  
fclose($fp2);  
 
return $filename;  
}  


 $img=GrabImage("http://pic2.ooopic.com/01/03/51/25b1OOOPIC19.jpg","logo.gif");
 ### 其中得到本地名称logo.gif,可以指定目录  
if($img){  
echo ‘<img src="‘.$img.‘">‘;  
}else{  
echo "false";  
}  


 ?>
