Homephp教程php手册PHP删除指定文件夹所有文件代码

在php中系统自带了文件删除函数unlink,但是此文件只是一个文件删除函数,如果我们要删除指定目录中的文件就需要配合其它方法来操作了,下面我给各位朋友介绍。

删除指定文件夹所有文件

 代码如下 复制代码

$cacheDir = '../cache/runtime';
$dh = opendir($cacheDir);
while ( $file = readdir($dh) ) {

if (($file == '.') || ($file == '..')) { continue; }

if (file_exists( $cacheDir . '/' .$file)) {
if (!unlink($cacheDir . '/' . $file)) {
break;
}
}
}

上面只能删除目录中的文件,不能删除目录中的目录或目录下的文件,我这里既然讲到也给大家提供一个函数

 代码如下 复制代码

function   deltree($dirList){  
  chdir($dirList);  
  $handle=opendir('.');  
  while   (($file=readdir($handle))"")   {  
  if(is_file($file))  
  unlink($file);  
  if(is_dir($file)   &&   $file"."   &&   $file".."){  
  deltree($file);  
  chdir('..');  
  rmdir($file);  
  }  
  }  
  closedir($handle);    
  }  
deltree('test');  

上面使用的是递归遍历目录然后进行删除文件再删除目录了

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),
