Need help with preg_match

Copy linkTweet thisAlerts:
May 15.2007

Hey,

I know basically what I have to do to achieve what I want, but preg_match is so confusing with its search criteria and characters. I want to make a loop that reads all the files in a folder (they are all images) and sort them by their initial filename and the number included.

Each folder will have something like this:
large1.jpg
large2.jpg
large3.jpg
thumb1.jpg
thumb2.jpg
thumb3.jpg
main1.jpg
main2.jpg
main3.jpg
original1.jpg
original2.jpg
original3.jpg

I want to sort it something like “original[0-9].jpg” and either put it in array or whatever so I can count the total (like 3 of each) and use each one. I have the right loop I think for the files, but I don’t know how to do the filename filter. Any help would be appreciated. Thanks.

@DARTHTAMPONMay 15.2007 — something like this might lead you in the right direction. Spend a little time researching associated arrays. (note this is untested code)

[code=php]
foreach ($file in dir)
{
#chop off the numbers and .jpg
$filename = @preg_replace('/^(.+)([0-9]{1,}.jpg)$/','\1',$file);
if ($fileCounts[$filename] != null)
{
$fileCounts[$filename]++;
}
else
{
$fileCounts[$filename] = 1;
}
}
[/code]

@bokehMay 15.2007 — [code=php]if ($fileCounts[$filename] != null)
{
$fileCounts[$filename]++;
}
else
{
$fileCounts[$filename] = 1;
}
}
[/code][/QUOTE]or just:[code=php]@$fileCounts[$filename]++;[/code]

Success!
