Randomly select file in PHP

问题:

I'd like to use the 'include' keyword in php to randomly select a file from a folder and output the contents. How would I do this?

Thanks.

回答1:

Assuming you know the folder where the files are and that the files are PHP files:

$phpFiles = glob('/path/to/files/*.php');

if (empty($phpFiles) === false)
{
    $randomFile = $phpFiles[array_rand($phpFiles)];
    include($randomFile);
}

回答2:

glob() would read filenames into array.
and then you can shuffle this array and pick a random item.

use glob to get an array of files. shuffle the array. array_shift the first file off of the array. Include it.
