How do you want to compare them?

What about [man]strcmp/man?

[andy_117]

function validateMembersNum($x,$y)
{
echo("the first val". trim($x));
echo("<br />");
echo("the second val". trim($y));
$z = strcmp(strtolower($x) , strtolower ($y));
if($z == 1)
{
die("if correct return");

}
else
{
	die ("kill if string dont match");
}

Well, there are 2 things you need to do:

1. Explain what exactly are you trying to do, and why are you unable to accomplish it.

2. Comment your code.

validateMembersNum($membershipnumber = odbc_result($result,2),$membersnumber);
this is the call $membersnumber is a var posted in from a form and $membershipnumber is a value retuned from a database.

function validateMembersNum($x,$y)
{
//x and y are the passed parameters
// now i want to check that they are the same and return if they are and die if they are not the same

echo("the first val". trim($x));

echo("<br />");
echo("the second val". trim($y));
$z = strcmp(strtolower($x) , strtolower ($y));
if($z == 1)
{
	die("if correct return");		
}
else
{
	die ("passssssssssss");
}

}//end function
hope this help
