PHP uses the Glob function to quickly query the method of the specified directory file,

This example describes how PHP uses the Glob function to quickly query a specified directory file. Share to everyone for your reference. Specific as follows:

PHP searches the current directory for all files, the code is as follows:
Copy CodeThe code is as follows: $array = Glob (' *. * ');
Print_r ($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
[Ten] = 9.php
)
*/
To search for PHP files with the. PHP results, the code is as follows:
Copy CodeThe code is as follows: $array = Glob (' *.php ');
Print_r ($array);

/*

[2] = 11.php
[3] = 6.php
[4] = 7.php
[5] = 8.php
[6] = 9.php
)
*/
The search includes a php,aspx file with the following code:
Copy CodeThe code is as follows: $files = Glob (' *.{ Php,aspx} ', glob_brace);
Print_r ($files);
/*

[0] = 1.php
[1] = 10.php
[2] = 11.php
[3] = 6.php

Print_r ($files);

Array
(

[1] = d:www.jb51.net-15.php
[2] = = d:www.jb51.net-15. php
)
What the Glob () function can do is more powerful than the Scandir () function and can search for files in a certain pattern.
