PHP使用glob方法遍历文件夹下所有文件的实例

<?php
$path = dirname(__FILE__);
$result = traversing($path);
print_r($result);

function traversing($path){
 $result = array();
 if($handle = opendir($path)){
  while($file=readdir($handle)){
   if($file!='.' && $file!='..'){
    if(strtolower(substr($file, -4))=='.php'){
     array_push($result, $file);
    }
   }
  }
 }
 return $result;
}
? 

<?php
$path = dirname(__FILE__);
$result = glob($path.'/*.php');
print_r($result);
? 

Array
(
[0] =  /home/fdipzone/a.php
[1] =  /home/fdipzone/b.php
[2] =  /home/fdipzone/c.php
)
