The first step. First, use regular expressions to extract all from the article.

Copy the code The code is as follows:

 
$message //Article content
//Regular (this is not yet) 
$reg = "/]*src="(http://(.+ )/(.+).(jpg|gif|bmp|bnp))"/isU"; 
//Store the extracted img address into the $img_array variable
preg_match_all($reg, $message, $img_array, PREG_PATTERN_ORDER); 
//Filter duplicate images
$img_array = array_unique($img_array[1]); 

Step 2. Loop the $img_array array. Save images and replace article positions

Copy code The code is as follows:

 
foreach ($img_array as $img){ 
//Determine whether the image is on your own website
if('xxx.com' != get_domain($img)){//If the image is not on your own server
//Read the image file
$Gimg = new GetImage(); 
$Gimg->source = $img; 
$Gimg->save_to = './data/temp/'; 
$FILE = $Gimg ->download(); //Move the picture to local location
//Save it to the album to get the location where the picture is saved
$img_path = pic_save($FILE,0,''); 
//Text path Replace 
$message = str_replace($img, $img_path, $message); 
} 
} 

.... At this time, the image in $message has been replaced with The local address of your own server, and the image is also saved to your own server.

Copy the code The code is as follows:

 
//The following function and class are found from the Internet. 
//Get the domain name from the url
function get_domain($url){ 
$pattern = "/[w -]+.(com|net|org|gov|cc|biz|info|cn)(.(cn|hk))*/"; 
preg_match($pattern, $url, $matches); 
if(count($matches) > 0) { 
return $matches[0]; 
}else{ 
$rs = parse_url($url); 
$main_url = $rs[ "host"]; 
if(!strcmp(long2ip(sprintf("%u",ip2long($main_url))),$main_url)) { 
return $main_url; 
}else{ 
$arr = explode(".",$main_url); 
$count=count($arr); 
$endArr = array("com","net","org","3322") ;//com.cn net.cn etc.
if (in_array($arr[$count-2],$endArr)){ 
$domain = $arr[$count-3]."." .$arr[$count-2].".".$arr[$count-1]; 
}else{ 
$domain = $arr[$count-2].".".$arr [$count-1]; 
} 
return $domain; 
}// end if(!strcmp...) 
}// end if(count...) 
 }// end function
