How to extract data between strings

[sladex]

Hi,
Can you help me with that.
I'm tried few times, but failed.
I want to extract numbers from the name of file.

File name':P-65002-xh0dICiqQS-1.jpg

How to get these numbers between P- and - ?

I tried like that:

<?php

$text = 'P-65002-xh0dICiqQS-1.jpg'; 
preg_match("P-(.*)-", $text, $matches); 
$value = $matches[1]; 

echo"$value";
 ?>

But I'm sure that part: preg_match("P-(.*)-" has to be changed.
I don't know parrameter that should go there.


Can anyone help me with that?
Thank You very much.

<?php
$a=explode("-",$text);
echo $a[1];
?>

Hmm...it's working for one file, but when I have all list of files, its not working.
Let's say I have list of files:

P-100208-UpYdMeMtcm-1.jpg
P-100216-4MwGRw5swv-1.jpg
P-100217-suHqW1kFOf-1.jpg
P-100218-wsgX3Y8v77-1.jpg
P-100219-Feclv8jfVk-1.jpg
P-100220-Pc6D8F7JNd-1.jpg
P-10054-2zWg4pJOid-1.jpg
P-100896-LbV5S2p98S-1.jpg
P-100897-02YW6j9jst-1.jpg
P-100899-VxvwjVdxbW-1.jpg
P-100901-3oICxPu8Ul-1.jpg
P-100902-hR3wqSFoC4-1.jpg
P-100908-aICRXta8R2-1.jpg
P-100910-xKo8CiuVuv-1.jpg
P-100912-9M4YoqvxNX-1.jpg
P-100914-gxT7upzalv-1.jpg
P-100918-wPkDryqSjm-1.jpg
etc...

And if I using that code:

  <?php
if ($handle = opendir('games/screen/4/')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
        $wordChunksLimited = explode("-", $file);
            echo "$wordChunksLimited[0]\n";
        }
    }
    closedir($handle);
}
?>

Then Is exploding only

P
P
P
P
P
etc..

Do anyone have solution for this?
Thank You.

  <?php 
//assuming you have "P-100208-UpYdMeMtcm-1.jpg" in that directory,
if ($handle = opendir('games/screen/4/')) { 
    while (false !== ($file = readdir($handle))) { 
        if ($file != "." && $file != "..") { 
        $wordChunksLimited = explode("-", $file); 
            echo $wordChunksLimited[2]."\n"; // $wordChunksLimited[0] would be "P", $wordChunksLimited[1] would be "100208", $wordChunksLimited[2] would be "UpYdMeMtcm" and $wordChunksLimited[3] would be "1"... explode function returns an array
        } 
    } 
    closedir($handle); 
} 
?>

preg_match('/[A-z]{1}-(.*)-[0-9]{1}\.[A-z]{3,4}/', $text, $matches); 

for 65002-xh0dICiqQS
and

preg_match('/-(\d+)-/', $text, $matches); 

for 65002
