How to retrieve files deleted from the recycle bin using PHP to delete files and folders. Use the two functions unlink and rmdir

Let’s take a look at the code first

The code is as follows:

<? 
function deldir($dir) { 
//先删除目录下的文件: 
$dh=opendir($dir); 
while ($file=readdir($dh)) { 
if($file!="." && $file!="..") { 
$fullpath=$dir."/".$file; 
if(!is_dir($fullpath)) { 
unlink($fullpath); 
} else { 
deldir($fullpath); 
} 
} 
} 
closedir($dh); 
//删除当前文件夹: 
if(rmdir($dir)) { 
return true; 
} 
else { 
return false; 
} 
} 
?>

unlink() function is used to delete files . Returns true if successful, false if failed. The rmdir() function is used to delete empty directories. It attempts to delete the directory specified by dir. The directory must be empty and must have appropriate permissions.
An example: Delete all ".svn" folders under a certain folder (including their contents also need to be deleted).

The code is as follows:

<?php 
function delsvn($dir) { 
$dh=opendir($dir); 
//找出所有".svn" 的文件夹: 
while ($file=readdir($dh)) { 
if($file!="." && $file!="..") { 
$fullpath=$dir."/".$file; 
if(is_dir($fullpath)) { 
if($file==".svn"){ 
delsvndir($fullpath); 
}else{ 
delsvn($fullpath); 
} 
} 
} 
} 
closedir($dh); 
} 
function delsvndir($svndir){ 
//先删除目录下的文件: 
$dh=opendir($svndir); 
while($file=readdir($dh)){ 
if($file!="."&&$file!=".."){ 
$fullpath=$svndir."/".$file; 
if(is_dir($fullpath)){ 
delsvndir($fullpath); 
}else{ 
unlink($fullpath); 
} 
} 
} 
closedir($dh); 
//删除目录文件夹 
if(rmdir($svndir)){ 
return true; 
}else{ 
return false; 
} 
} 
$dir=dirname(__FILE__); 
//echo $dir; 
delsvn($dir); 
?>

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.

PHP Dependency Injection: Boost Code MaintainabilityPHP Dependency Injection: Boost Code MaintainabilityMay 07, 2025 pm 02:37 PM

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.

How to Implement Dependency Injection in PHPHow to Implement Dependency Injection in PHPMay 07, 2025 pm 02:33 PM

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.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
