How to define multiple patterns in php glob()

问题

My code to get all images from a directory

$dirname = "uploads/";

$images = glob("{$dirname}*.png, {$dirname}*.jpeg, {$dirname}*.jpg, {$dirname}*.gif");

foreach($images as $image) {

    echo "<img src='{$image}' class='files_main'>";

}

This works for one type of image but fails with multiple please give the syntax of defining multiple patterns in the glob().

回答1:

You can use the GLOB_BRACE constant

GLOB_BRACE - Expands {a,b,c} to match 'a', 'b', or 'c'

e.g.

$dirname = 'uploads/';
glob("$dirname*.{png,jpeg,jpg,gif}", GLOB_BRACE);
