Hi list. Basically, I'm still learning new things about php and I was wondering if things inside an if statement get 'looked at' by a script if the condition is false. For example, would this mysql query get executed if $number = 0 ? If ($number == 1) {
    mysql_query($blah)
} I know that's not really valid php, but hope it gets my point across. I was just wondering from an optimisation perspective, as I don't want sql commands being executed when they don't need to be (unnecessary server usage). Thanks in advance for your responses. Alex.

Stuff inside an if statement will be compiled (So it has to be free of syntax errors and such), but it won't be executed unless the condition is true. Regards, Adam Zey.
