For Loop?

[Gunderak]

Could anyone possible explain what this does and how it is useful?
When I use it, it just returns the maximum number it can.

PHP Code:

for(temp.i = 0; temp.i < 99 temp.i ++){

It repeats all the script within the loop for as many times as defined.

PHP Code:

// Initiate the variable 'temp.i' at 0
// If temp.i < 20, increase temp.i++
// for each time it needs to do this(temp.i++), it will run the 
// script inside of the loop
for(temp.i = 0; temp.i < 20; temp.i ++) {  
  echo(i);
} 


This is useful when you need to do something repetitive, like compare a single value to each element in an array.

PHP Code:

temp.val = 67;
temp.arr = {2,56,23,34,6,78,67,2,34,45,67,8,23424,6,854,21};
// Create a loop the size of the array
for (temp.i = 0; temp.i < arr.size(); temp.i++) {
  // compare the defined val to each element in the array
  // by using the defined temp.i(which is incremented each loop)
  // to scan through the entire array
  if (val == arr[temp.i]) {
    echo("Teehee! Found you!");
    // there's no need to keep scanning the array, so you
    // may as well stop looping, which you do via break
    break;
  }
}

Ah ok, thanks for that.
I understand now.
