[SOLVED] Finding highest number

[Timma]

I have some files in a folder called "file1.png", "file2.png", "file3.png", etc.

I was just wondering if there was a way to find which the highest number in the file name.

if you put em into an array, and natsort() them... the bottom one'd be your highest #

Dang, any method of getting all the files in a folder into an array? Mostly because the folder gets updated, and then that would just be another thing to change every update.

<?php

$filenames = array();

$dir = dir("directoryname");

while (($file = $dir->read()) != false) {
$filenames[] = $file;
}

$dir->close();

?>

if you glob() the folder... you can easily grab all the files into an array...

 

$files=glob('path/file*.png');

natsort($files);

$high=$files[count($files)-1];

 

 

 

 

chigley - my way's faster ;-)

Alright, thanks a lot you two.

Gnash... never come across [pre]glob()[/pre] before..

[Timma]

Error Time.

I used the glob method, but that only returns the number 9, when I was testing with 16 files.

 

Secondly, I need a way to remove the "images/file .png", but leave the number. So possibly just counting the amount of files in the folder and then finding the highest. Obviously I don't know how to do this or I wouldn't be saying it 

[taith]

if you print_r($files); after the natsort... how's it sorting it?

[Timma]

Well, I found a different way to do it, after looking in the manual at glob().

 

foreach (glob("images/comic/comic*.jpg") as $notused) {
    $last++;
}

[taith]

that is assuming that you dont skip any numbers

[Timma]

I'll try not to 

 

Also [solved]

[kathas]

why dont you count() the files array???

 

it is the same as your last post

[Timma]

Thanks, I took that into consideration.

It's mega short!

 

$last = glob("images/comic/comic*.jpg");

$last = count($last);

 

Thanks!
