opendar sorting trouble

[ricky-spires]

hello.

 

im having some trouble getting the information i want back from a folder.

 

all i want to get back is the file names in numeric order.

 

i seem to also be getting directories listed.

 

my files are called 1.jpg, 2.jpg, 3.jpg etc up to 50.jpg

 

i have added the work page in the echo. at the moment i get this:

 

• Page
• Page
• Page 1
• Page 10
• Page 11
• Page 12
• Page 13
• Page 14
• Page 15
• Page 16
• Page 17
• Page 18
• Page 19
• Page 2
• Page 20
• Page 21

 

 

 

so i want to get rid of the first 2 and put the rest in order .

 

 

this is my code:

<?php
				
if ($pdfImage = opendir('assets/images/pages/')) {
						
while (false !== ($pageImage = readdir($pdfImage))) {
$pageImage = preg_replace('/\D/', '', $pageImage);

echo'<li><a href="'.$pageImage.'">Page '.$pageImage.'</a></li>'; 
}
closedir($pdfImage);
}
?>

it doesnt have to be opendir. if you know another way i would be happy to hear .

 

 

thanks

store in an array then sort the array using natsort

A simply way would be to use glob():

$files = glob('assets/images/pages/*.jpg');
sort($files);

Edit: Er, yes, natsort() solves your other problem. I missed that. Good call, Barand!

great.

 

thanks

 

this worked:

<?php
				
					$files = glob('assets/images/pages/*.jpg');
					
					$pageImg = preg_replace('/\D/', '', $files);
					natsort($pageImg);
					
					foreach($pageImg as $file){
						echo'<li><a href="'.$file.'">Page '.$file.'</a></li>';
					}
				
					?>
