[SOLVED] convert script snippet to function

[AV1611]

this simple script verifies that a number is VALID based on the following

 

number must be 4 NUMBERS decimal 3 NUMBER (4455.333)

first number must be > 100 (0100.123 is valid but 0099.123 is not valid)

number can contain no alpha characters (a123.123 is is not valid)

 

QUESTION:

 

can someone help me convert this to a function? I simply want to function to either output "VALID" or "INVALID" or TRUE/FALSE

 

$t1="4455.003";
// begin test of input number $t1
$TL = strlen($t1);
// Verify the number is 8 Characters Long
if($TL != {
echo '<br/>'.$t1.' Is Not A Valid Part Number Series...';
die();
}
$split=explode('.',$t1);
// Verify the number is divisible by a "."
if(!isset($split[0]) || !isset($split[1]) || isset($split[2])){
echo '<br/>'.$t1.' Is Not A Valid Part Number Series...';
die();
}
$L1=$split[0];
$L2=$split[1];
$LL1 = strlen($L1);
$LL2 = strlen($L2);
// Verify the number was divided in to ONLY two parts,
// not three and that the parts only contain numbers and
// the first number is 4 digits and the second number is 3 digits and
// the first number is at least 0100
if($LL1 != 4 || $LL2 !=3 || !is_numeric($L1) || !is_numeric($L2) || $L1 <= 99) {
echo '<br/>'.$t1.' Is Not A Valid Part Number Series...';
die();
}
else{
echo $L1.".".$L2." is a VALID Number";
echo "<br/>";
}

Grr... beaten

That really is quite easy... I need to start writing functions instead of doing everything long each time

 

Thanks for all the help.  That may be the clearest example of how to create a function from simple script.  It will go a long way in my learning...
