PHP uses the Glob function to quickly query the method of specifying a 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:

$array = Glob (' *. * '); Print_r ($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:

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

The search includes a php,aspx file with the following code:

$files = Glob (' *.{ Php,aspx} ', glob_brace);  Print_r ($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) */

Search for PHP files with 1 in the specified directory

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

Return the absolute path to the file with the following code:

$files = Array_map (' Realpath ', $files);  Print_r ($files);   Array (     [0] = d:www.php.cn-15.php     [1] = d:www.php.cn-15.php     [2] = d:www.php.cn-15. php)

What the Glob () function can do is more powerful than the Scandir () function and can search for files in a certain pattern.

I hope this article is helpful to everyone's PHP programming.
