How to quickly query files in a specified directory using php's glob function

The example in this article describes how PHP uses the glob function to quickly query files in a specified directory. Share it with everyone for your reference. The details are as follows:

php searches all files in the current directory, 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 
    [10] => 9.php 
) 
*/

Search for php files with .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 
) 
*/

Search for files including php, aspx, the code is as follows:

$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 
) 
*/

In the specified directory Search for php files that open with 1

$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 
) 
*/

and return the absolute path of the file. The code is as follows:

$files = array_map('realpath',$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 
)

The glob() function can do more powerful things than the scandir() function and can search for files according to a certain pattern.
