I'm trying to get information from filenames.
It loops through everything in the directory, now I just need it to chop them up.

The format:
number-name.ext

I need $number to equal everything before the first dash, and $name to equal everything after the dash until the last period.

I've been trying a bunch of functions, but I can't get it quite right.

current code:

PHP Code:

$handle = opendir('scans/3/');
while (false !== ($file = readdir($handle))){
  $extplace = strchr($file, ".");
  $number = substr($file,0,strpos($file, "-"));
  $name = strchr($file, "-");
  echo $number.'/'.$name.'<br />';
} 


Currently it get's the number correctly, I just don't know how to do the name.

echo will be something like
10/-name.jpg


EDIT:
nvm, I'm pretty sure this worked

PHP Code:

  $name = strchr($file, "-");
  $name = substr($name, 1, strlen($name)-5); 


preg_match('/^([0-9]+)-([^.]+)/', $file, $match);

The above will match the number and name (without the extention):

$number = $match[0];
$name = $match[1];

Why don't you split on the '/' then ?
First, get the extension, then remove it from the string, and then split:

PHP Code:

<?php
$handle = opendir('scans/');
while (false !== ($file = readdir($handle))){
  if(($file!=='.') && ($file!=='..')){
    $ext = pathinfo($file, PATHINFO_EXTENSION);
    $clean=str_ireplace(".$ext", "", $file);
    $ary=explode("-", $clean);
    if(sizeof($ary)==1){
      $name=$ary[0];
      $nbr="no number in this filename";
    }
    else{
      $name=$ary[1];
      $nbr=$ary[0];
    }
    print <<<txt
FS filename: $file
name is $name, number is $nbr
------------------------------

txt;
  }
}

My results are:

$number = $match[0];
$name = $match[1];

Little correction:
$number = $match[1];
$name = $match[2];

$match[0] - contains all string under pattern

Yes, you are right! Thanks for the correction.
