reading file and highlighting a line.

[Mad_T]

Hi
I'm reading a file and then displaying it line by line.
What I want is if the user specifies an 'id' then the corresponding line is BOLD.

The URL I'm trying with is file.php?id=2, so all lines should be normal but line 2 should be bold.

This is what I've got, but it doesn't seem to work.

foreach ($lines as $line_num => $line)
{

   			if ($line_num === $_REQUEST['id']) {
   			echo "<b>BLAH</b>";
   			} else {
   			echo "BLAH";
		}
}

Any ideas ? thanks

[font=monospace]$_REQUEST['id'][/font], like all variables from a form, is a string. If you're comparing it to an integer, then a type-sensitive comparison with [font=monospace]===[/font] will fail, because a string is not an integer.

Thanks for the reply.

Could you point me in the right direction for comparing it.

Thanks

The first on the list of comparison operators.
