ifs within ifs

[Anon]

How can I put an if within an if? I can with elseif, but once elseif finds a true value, it stopps. How would I go about this?

You can use one "if", multiple "elseif"s, and end with one "else". Like this:

if ($blah=="A") { echo "A"; }
elseif ($blah=="B") { echo "B"; }
elseif ($blah=="C") { echo "C"; }
else { echo "Not A, B, or C."; }

You can use "if"s within "if"s. Like this:

if ($blah=="A")
{
if ($show=="Yes") { echo "Here is an A."; }
else { echo "You don't want to see an A."; }
}
elseif ($blah=="B")
{
if ($show=="Yes") { echo "Here is a B."; }
else { echo "You don't want to see a B."; }
}
else { echo "No A's and no B's."; }

My example is meaningless except to show you how if's go within if's. Have fun.

Arron's response is probably what you needed. But when you find yourself with a long sequence of if-then-else blocks you might be better using a "switch" statement. Not necessarily more efficient, but I find them easier to read and maintain:
