在php中我们经常使用写一些简单的采集功能,这样可以自动把远程服务器的图片或资源直接采集保存到本地服务器中,下面我来给大家详细介绍远程图片并把它保存到本地几种方法.
例1,代码如下:
-
-
-
-
-
- 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;
- }
-
- 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);
-
- $fp2=@fopen($filename,'a');
- fwrite($fp2,$img);
- fclose($fp2);
- return $filename;
- }
例2,代码如下:
- <?php
-
-
-
-
-
-
-
-
-
-
-
-
- function GrabImage($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;
- }
-
-
- $img=GrabImage("http://www.phpfensi.com","");
- if($img):echo '<pre><img src="'.$img.'"></pre>';else:echo "false";endif;
-
- ?>
dedecms中的,代码如下:
- if(!emptyempty($saveremoteimg))
- {
- $body = stripslashes($body);
- $img_array = array();
- preg_match_all("/(src|SRC)=["|'| ]{0,}(http:
- $img_array = array_unique($img_array[2]);
- set_time_limit(0);
- $imgUrl = $img_dir."/".strftime("%Y%m%d",time());
- $imgPath = $base_dir.$imgUrl;
- $milliSecond = strftime("%H%M%S",time());
- if(!is_dir($imgPath)) @mkdir($imgPath,0777);
- foreach($img_array as $key =>$value)
- {
- $value = trim($value);
- $get_file = @file_get_contents($value);
- $rndFileName = $imgPath."/".$milliSecond.$key.".".substr($value,-3,3);
- $fileurl = $imgUrl."/".$milliSecond.$key.".".substr($value,-3,3);
- if($get_file)
- {
- $fp = @fopen($rndFileName,"w");
- @fwrite($fp,$get_file);
- @fclose($fp);
- }
- $body = ereg_replace($value,$fileurl,$body);
- }
- $body = addslashes($body);
- }
- ?>
例4,代码如下:
- <?php
-
-
-
-
-
-
-
-
-
-
- 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;
- }
- $img=GrabImage('http://www.phpfensi.com/static/image/common/logo.png','');
- if($img){echo '<pre><img src='.$img.'></pre>';}else{echo 'false';}
- ?>
