php使用glob函数快速查询指定目录文件的方法,

本文实例讲述了php使用glob函数快速查询指定目录文件的方法。分享给大家供大家参考。具体如下:

php搜索当前目录所有文件,代码如下:

复制代码 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:

复制代码 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:

复制代码 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

复制代码 代码如下:

$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:

复制代码 代码如下:

$files = array_map('realpath',$files); 
print_r($files); 
 
Array
(
    [0] => D:www.jb51.net-15.php
    [1] => D:www.jb51.net-15.php
    [2] => D:www.jb51.net-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。
