php opendir()函数用于打开目录，通常与readdir()和closedir()函数一起用来读取目录下所有文件(即遍历目录)，本文章向大家介绍php使用opendir()函数列出目录下所有文件的实例。

实例一：

使用opendir()列出目录下所有文件

<?php
 
   $dr = @opendir(&#39;/tmp/&#39;);
   if(!$dr) {
     echo "Error opening the /tmp/ directory!<BR>";
     exit;
   }
 
   while(($files[] = readdir($dr)) !== false);
 
   print_r($files);
?>

实例二：

列出目录下所有文件

<?php  
 $dirname = "C:\\Apache\\bin";
 $dir = opendir( $dirname );
  
 while( false != ( $file = readdir( $dir ) ) )
 {
  if( ( $file != "." ) and ( $file != ".." ) )
  {
   $file_list .= "<li>$file</li>";
  }
 }
 closedir( $dir );
?>
 
<html>
 <head>
 <title>列出目录下所有文件</title>
 <head>
 <body>
 <p>Files in <?php echo( $dirname ); ?> </p>
 <ul>
  <?php echo( $file_list ); ?>
 </ul>
 </body>
</html>
