Fetch specific images from a directory with php

Question

$dirname = "media/images/iconized/";
$images = glob($dirname."*.jpg");
foreach($images as $image) {
echo '<img src="'.$image.'" /><br />';
}

With the above code I can fetch all images in a folder.But, I am not able to fetch particular images from a folder.

For example:
I have images in a folder as:

1. low_0.jpg
2. low_1.jpg
3. low_2.jpg
4. med_0.jpg
5  med_1.jpg
6. med_2.jpg

From these images how to grab only the images that starts with med ?
Thanks for your time

Answer 1

Change the glob() command from:

$images = glob($dirname."*.jpg");

To:

$images = glob($dirname."med_*.jpg");

The * is a wildcard; it'll fill in the gap (in this case, numbers).

Full code:

$dirname = "media/images/iconized/";
$images = glob($dirname."med_*.jpg");
foreach($images as $image) {
    echo '<img src="'.$image.'" /><br />';
}
