array_shift和explode有效吗？

Question

I wonder if they disabled array_shift in > PHP 5.2.6

$realid = array_shift(explode("-", $id));

Because this code was working fine on my server PHP Version 5.2.6, while is not working in another server with higher PHP version.

If so, is there anyway I can do the following:

For a URL like this 87262-any-thing-here.html how can I get only the number, 87262, so that I will use it to call any entry from database:

$qryrec="select * from mytable where id='$realid'";
$resultrec=mysql_query($qryrec) or die($qryrec);
$linerec=mysql_fetch_array($resultrec);

Is there any way to do the same without array_shift?

Answer 1

Use

$realid = explode("-", $id);
$realid = $realid[0];
