    Hey,

    array_shift seems to work on another server, but it does not on mine.

    The code is the following;

    $realid = array_shift(explode("-", $id));
    PHP:
    What I am trying to get done is the following;

    I have a URL, which is like [ example.com/48555-animal-name.html ]. How is it possible to ONLY get the ID which is 48555, to call an entry from the database?

    $realid = array_shift(explode("-", $id));
$qryrec="select * from animals where id='$realid'";
$resultrec=mysql_query($qryrec) or die($qryrec);
$linerec=mysql_fetch_array($resultrec);
$pcommon = ucwords($linerec[common]);
    PHP:
    Is there an another way of doing this, without using array_shift?

    Thanks,

<?php

$arrays = array(
    'example.com/48555-animal-name.html',
    'example.com/48555-345-animal-na3me.html',
    '48555-animal-name.html'          
);

foreach ($arrays as $item):
    preg_match('/.*\/?([0-9]+)-/U', $item, $res);
    echo $res[1];
endforeach;

    That really does look like you are doing it the hard way.

    I'd try something like this, takes a few more steps but is readable and debugable. 
    
$url = "example.com/48555-animal-name.html";
$pos = 1; // how many / are expected before the id

$bits =explode('/', $url);
$idbits = explode('-',$bit[$pos]);
$id = $idbits[0];

    edit: ThePHPMaster is onto it, preg is faster and allows subtle changes as per the example

    Just use regex, and var_dump. Then just put the match[1] into a variable which you will use.
