It's not quite making sense to me though... My understanding of IF

for my knowledge :)
No, that's not how it works. If the condition is met, the contents of
the if block are executed. If not, and there is an ELSE block, those
commands are executed. Then, the script continues after the whole
if/then/else structure.
Maybe you are thinking of an IF/ELSEIF/ELSEIF/.../ELSE structure?
if ( $row[5] == "Level1" ) {
// your commands
} elseif ( $row[5] == "Level2" ) {
// your commands
} else {
// your commands
}
This would work in the way you are thinking. Hope this helps your
understanding.
Hi Roberto,
Thanks for pointing that out, I think it looks better then having a
bunch of related if statements with an else at the end anyway. :)
Always helps when you use the right tools for the job! :)
well, the right tool for the job is a matter of choice.
Maybe I want to use a switch statement instead.
switch($row[5]) {
case 'Level1':
// Your code
break;
case 'Level2':
// Your code
break;
default:
// if none of the case statements above match, then this will be used
break;
}
Just another way to complete the same task
