php gets remote image and saves it locally_PHP tutorial-PHP Tutorial-php.cn

In PHP, we often write some simple collection functions, which can automatically collect and save images or resources from remote servers directly to the local server. Now I will introduce to you in detail several methods of remote images and saving them locally.

Example 1

The code is as follows

Copy code

代码如下

复制代码

/*
*功能：php多种方式完美实现下载远程图片保存到本地
*参数：文件url,保存文件名称，使用的下载方式
*当保存文件名称为空时则使用远程文件原来的名称
*/
function getImage($url,$filename='',$type=0){
    if($url==''){return false;}
    if($filename==''){
        $ext=strrchr($url,'.');
        if($ext!='.gif' && $ext!='.jpg'){return false;}
        $filename=time().$ext;
    }
    //文件保存路径
    if($type){
  $ch=curl_init();
  $timeout=5;
  curl_setopt($ch,CURLOPT_URL,$url);
  curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
  curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
  $img=curl_exec($ch);
  curl_close($ch);
    }else{
     ob_start();
     readfile($url);
     $img=ob_get_contents();
     ob_end_clean();
    }
    $size=strlen($img);
    //文件大小
    $fp2=@fopen($filename,'a');
    fwrite($fp2,$img);
    fclose($fp2);
    return $filename;
}

/*
*Function: PHP has multiple ways to perfectly download remote images and save them locally
*Parameters: file url, save file name, Download method used
*When the saved file name is empty, the original name of the remote file is used
*/
function getImage($url,$filename='',$type=0) {
if($url==''){return false;}
if($filename==''){
$ext=strrchr($url,'.');
if($ext!='.gif' && $ext!='.jpg'){return false;}
/> //File saving path
if($type){
$ch=curl_init();
$timeout=5;
curl_setopt($ch,CURLOPT_URL,$url );
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch,CURLOPT_CONNECTTIMEOUT,$timeout);
$img=curl_exec($ch);
curl_close( $ch);
}else{
ob_start();
readfile($url);
$img=ob_get_contents();
ob_end_clean();
/> }
$size=strlen($img);
//File size
$fp2=@fopen($filename,'a');
fwrite($fp2 ,$img);
fclose($fp2);
return $filename;
}

Example 2

代码如下

复制代码

//
// Function: 获取远程图片并把它保存到本地
//
//
// 确定您有把文件写入本地服务器的权限
//
//
// 变量说明:
// $url 是远程图片的完整URL地址，不能为空。
// $filename 是可选变量: 如果为空，本地文件名将基于时间和日期
// 自动生成.

function GrabImage($url,$filename="") {
if($url==""):return false;endif;

if($filename=="") {
$ext=strrchr($url,".");
if($ext!=".gif" && $ext!=".jpg"):return false;endif;
$filename=date("dMYHis").$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;
}

$img=GrabImage("http://www.bkjia.com","");
if($img):echo '

<img src="'.$img.'">

';else:echo "false";endif;

The code is as follows

Copy code

<🎜>//
// Function: Get the remote image and save it locally
//
//< br />// Make sure you have the permission to write the file to the local server
//
//
// Variable description:

// $filename is an optional variable: if empty, the local file name will be automatically generated based on time and date
// Automatically generated.<🎜><🎜>function GrabImage($url,$filename="" ) {
if($url==""):return false;endif;<🎜><🎜> if($filename=="") {
$ext=strrchr($url," .");

$filename=date("dMYHis").$ext ;
