How to split string which not having spaces or etc.

[ghjk]

I want to split a string which not having spaces or etc. Ex:START44.98. It always having "START" and values is different.ex:00 .00, 000.00,0.00. I want to take only the numeric value. How can i do that. I can't use split. Because value will vary.
This is what i have done so far.

[PHP]
$mn=split(" ",$message) ;//start33.33 06-08-2008 15:02 1Stop
$mnn = $mn[0];//start33.33
[/PHP]

If you have the string "START123.4 56" and you want 123.456 out as a numeric value the following code will do just that.

[PHP]
$lcVar = "START123.4 56";
$lcNum = str_replace("ST ART", "", $lcVar) ;
$lnNum = floatVal($lcNum ) ;
echo $lnNum;
[/PHP]

Alternatively you could use
[PHP]
$lcVar = "START123.4 56";
$lcNum = substr($lcVar, 5) ;
$lnNum = floatVal($lcNum ) ;
echo $lnNum;
[/PHP]

There are many more solutions, some more complicated and some more thorough but if the format is guaranteed then the above offerings should work for you.
