PHP - Get Rid Off The Last Delimiter

I am trying to split a variable only if it has an integer. Here is what I want to do:

$id = 1234-54678;

should be split into and then placed into two variables:

$id1 = 54678;
$id2 = 1234;

Sometimes the variable may not have a delimiter in which case I would like it to be $id1

example:
$id = 54678;

should go directly to

$id1 = 54678;

I am a php rookie and don't know which way is best to do this (explode, split, etc.) so I would appreciate any help you can give me.

Hi New to php code, been trown in at the deep end.
Keep getting error message Warning: preg_replace(): No ending delimiter
it is to do with these 3 lines only

$is_sera = preg_replace("'","\"", $is_sera);
$is_sera = preg_replace("%","", $is_sera);
$is_sera = preg_replace("\?","", $is_sera);

can any one tell me what the ending delimiter error means/is

thanks in advance

I'm having trouble with a role in a wordpress site that I made
I think the script was that I installed another version, so I
some adjustments in it, among those changes have modified this function

if (@$_GET['src'] && !@$PHPTHUMB_CONFIG['allow_local_http_src'] && eregi('^http://'.@$_SERVER['HTTP_HOST'].'(.+)', @$_GET['src'], $matches)) {
   $phpThumb->ErrorImage('It is MUCH better to specify the "src" parameter as "'.$matches[1].'" instead of "'.$matches[0].'".'."\n\n".'If you really must do it this way, enable "allow_local_http_src" in phpThumb.config.php');
}


for this:

$phpThumb->ErrorImage('It is MUCH better to specify the "src" parameter as "'.$matches[1].'" instead of "'.$matches[0].'".'."\n\n".'If you really must do it this way, enable "allow_local_http_src" in phpThumb.config.php');

It was supposed to make some images appear as thumbnails on the home page
my site, but they do not appear and I got the following error:

Warning: preg_match() [function.preg-match]: No ending delimiter '^' found in /home/pontocom/public_html/wp-content/themes/Comfy/scripts/phpThumb/phpThumb.php on line 160



Is there some way that I can take to fix this error?

I am working on taking out the Deprecated functions from my site so while replacing ereg with preg_match I get the below error. Per a message I found on the internet it says to replace ereg with preg_match and everything should work. Can anyone assist me with fixing this error?

Error: Warning: preg_match() [function.preg-match]: Delimiter must not be alphanumeric or backslash
