php使用glob函数快速查询指定目录文件的方法

php搜索当前目录所有文件,代码如下:

$array = glob('*.*'); 
print_r($array );  
 
/* 
Array 
( 
    [0] => 1.php 
    [1] => 10.php 
    [2] => 11.php 
    [3] => 2.asp 
    [4] => 3.asp 
    [5] => 4.aspx 
    [6] => 5.html 
    [7] => 6.php 
    [8] => 7.php 
    [9] => 8.php 
    [10] => 9.php 
) 
*/

搜索以.php结果的php文件,代码如下:

$array = glob('*.php'); 
print_r($array );  
 
/* 
Array 
( 
    [0] => 1.php 
    [1] => 10.php 
    [2] => 11.php 
    [3] => 6.php 
    [4] => 7.php 
    [5] => 8.php 
    [6] => 9.php 
) 
*/

搜索包括有php,aspx 文件,代码如下:

$files = glob('*.{php,aspx}', GLOB_BRACE);  
print_r( $files ); 
/*  
Array 
( 
    [0] => 1.php 
    [1] => 10.php 
    [2] => 11.php 
    [3] => 6.php 
    [4] => 7.php 
    [5] => 8.php 
    [6] => 9.php 
    [7] => 4.aspx 
) 
*/

在指定目录搜索以1开的php文件

$files = glob('../05-15/1*.php'); 
 
print_r($files);  
 
/* 
Array 
( 
    [0] => ../05-15/1.php 
    [1] => ../05-15/10.php 
    [2] => ../05-15/11.php 
) 
*/

返回文件的绝对路径,代码如下:

$files = array_map('realpath',$files);  
print_r($files);  
 
Array 
( 
    [0] => D:www.gxlcms.com-15.php 
    [1] => D:www.gxlcms.com-15.php 
    [2] => D:www.gxlcms.com-15 .php 
)

glob()函数能做的事比scandir()函数更强大,可以按照某种模式搜索文件。

希望本文所述对大家的PHP程序设计有所帮助。
