PHP - Newbi variable question

[XeonGX]

Hello everyone,
I was wondering if there is a way to use only part of a php variable.
For example, if
<?php
$word = 'word1242';
echo $word;
?>
the output should be 1242, instead of word1242.
PS I've got a really long list, so I can't really change the $word to 1242.

Any help would be much appreciated.

in the list that you have, is "word" the thing you want to take off all of them ??

I dont really want to change the list, because its also used for something else.
I was looking more for a code when outputing the code.

So "word" is the string you want to remove from each item in the list, but without actually editing the list ??

foreach( array( 'word1234', 'word2345', 'word3456' ) as $word )
{
	printf( "%s<br />\n", substr( $word, 4 ) );
}

Draw your attention to

substr( $word, 4 )

I just tried this, it doesn't seem to work. It would output word1234 word2345 word 3456.

EDIT:
I played around with some javascript codes, and got it to work. lol

<script language="JavaScript"><!--
var word="<? echo $word; ?>";
var num1=word.charAt(4);
var num2=word.charAt(5);
var num3=word.charAt(6);
var num4=word.charAt(7);
var num=num1 + num2 + num3 + num4;
document.write(num);
//--></script>

If it's just and always the word, word you could:

<?php
$array = array('word1234', 'word4321');
foreach($array as $word) {
$word2 = explode("word", $word);
echo $word2[0];
}
?>
