How to load images and categorise with Unknown Prefix in filename? - php

Question

This is the code which loads images with different Prefix and the prefix is printed under every image.
I need Prefix as a Title of every set of images as Category of Images
CODE :
$images = glob($dirname . "*.jpg");
foreach ($images as $image) {
if (strpos($image, '#') !== false) {
} else {
?>
<li><?php $mn_img = str_replace("/thumbs", "", $image); ?>
<div class="th [radius]">
<a href="<?php echo $mn_img ?>"><img align="middle"
src="<?php echo $image; ?>"> </a>
</div>
<p style="text-align: center">
<?php
$str = $mn_img;
$s = end(explode("/", $str));
$e = explode(".", $s);
$n = explode('-', $e[0]);
$nm = $n[0];
if ($nm === 'non') {
echo 'general';
} else {
$title = str_replace("_", " ", $nm);
echo $title;
}
?>
</p>
</li>
<?php }
}
I expect the possibility :)
MY Prefix Format is
Manager_fileoriginalname_random.jpg
Manager_fileoriginalname_random.jpg
Manager_fileoriginalname_random.jpg
Manager_fileoriginalname_random.jpg
Prefix is "Manager"
Matketing_fileoriginalname_random.jpg
Matketing_fileoriginalname_random.jpg
Matketing_fileoriginalname_random.jpg
Matketing_fileoriginalname_random.jpg
Prefix is "Marketing"

Answer 1

is the preg_match function is what you want :
$returnValue = preg_match( '/(.*)_.*_.*$/', 'Manager_fileoriginalname_random.jpg', $matches );
in $matches[1] you have the prefix, you just need to remplace 'Manager_fileoriginalname_random.jpg' by your var $mn_img
If i can make and advise, can use parse_url() to extract url components : http://php.net/manual/fr/function.parse-url.php
