How to use loops

[horsebox]

I don't really know how to use loops I've been using the for loop for everything but I keep running into the same problem. When I need to do something once inside the loop like for example echo $variable it does it 50 times because its inside the loop. How do you do something only once when you're inside a loop thats set to repeat multiple times?

 

For example say I have the loop

for ($ibr=0; $ibr<=10; $ibr++) { $var[$ibr] = $ibr + 4; echo $variable; }

or whatever and need to repeat the $ibr + 4 part 10 times but only need to echo the $variable once what would I do? The way it is there it will echo the $variable 10 times.

Move it outside the loop?

Either like Daniel stated, or.. I guess you could do the pointless method of this..

for ($ibr=0; $ibr<=10; $ibr++) {
    $var[$ibr] = $ibr + 4; 
    if($ibr == '1') { 
        echo $variable;
    }
}
