The first step. First, extract all from the article using regular expressions.
Copy the code The code is as follows:
$message //Article content
//Regular (this is also regular) No)
$reg = "/]*/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 $img_array array. Save the image and replace the article position
Copy the code The code is as follows:
foreach ($img_array as $img){
//Determine whether it is Pictures on your own website
if('xxx.com' != get_domain($img)){//If this picture 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 image to local
//Save to The photo album gets the location where the picture is saved
$img_path = pic_save($FILE,0,'');
//Text path replacement
$message = str_replace($img, $img_path, $message);
}
}
....At this time, the image in $message has been replaced with the local address of your own server, and the image is also saved on your own server.
Copy the code The code is as follows:
//The following function and class are found from the Internet.
//Get the domain name from the url
function get_domain($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);
$endArr = array( "com","net","org","3322");//com.cn net.cn and other situations
if (in_array($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
// Load images from the remote bar to the local server class

The above introduces the remote image collection to local code in the acdsee 2009 license code PHP article, including the acdsee 2009 license code. I hope it will be helpful to friends who are interested in PHP tutorials.

PHP performance optimization can be achieved through the following steps: 1) use require_once or include_once on the top of the script to reduce the number of file loads; 2) use preprocessing statements and batch processing to reduce the number of database queries; 3) configure OPcache for opcode cache; 4) enable and configure PHP-FPM optimization process management; 5) use CDN to distribute static resources; 6) use Xdebug or Blackfire for code performance analysis; 7) select efficient data structures such as arrays; 8) write modular code for optimization execution.

Dependency injection provides object dependencies through external injection in PHP, improving the maintainability and flexibility of the code. Its implementation methods include: 1. Constructor injection, 2. Set value injection, 3. Interface injection. Using dependency injection can decouple, improve testability and flexibility, but attention should be paid to the possibility of increasing complexity and performance overhead.

Implementing dependency injection (DI) in PHP can be done by manual injection or using DI containers. 1) Manual injection passes dependencies through constructors, such as the UserService class injecting Logger. 2) Use DI containers to automatically manage dependencies, such as the Container class to manage Logger and UserService. Implementing DI can improve code flexibility and testability, but you need to pay attention to traps such as overinjection and service locator anti-mode.
