php uses the glob function to quickly query files in a specified directory,

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:

Copy code 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:

Copy code 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 includes php, aspx files, the code is as follows:

Copy code 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
)
*/

Search for php files opening with 1 in the specified directory

Copy code The code is as follows:

$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 of the file, the code is as follows:

Copy code The code is as follows:

$files = array_map('realpath',$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
)

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