If the expressions inside the parentheses () evaluate to true, the code between braces {} is executed. If it is false, then the code between braces is skipped. It’s worth mentioning that the code which follows the closing brace } is executed in any case, ‘coz it’s not part of the conditional statement.

Not much, heh? Well, I’m not a history teacher, so we’ll skip that stuff. You can read it yourself when you have a good catch on PHP. (more…)
