This tutorial highlighted 3 different constructs you can use in your PHP scripts to repeat a block of code: while loops, do-while loops and for loops.
The for loop can be used in a restrictive "counter" type situation. The while loop can be used in a situation where a section of given code may or may not be processed depending on a condition. The do-while loop can be used when a section of code must be executed at least once but future loops are then dependent on the conditional expression.
When writing loop statements it's imperative to pay attention to how the variables are set and the escape conditional statement reads. Logic errors and typos can cause a loop to repeat indefinitely!
...And this concludes the tutorial; all this talk of donuts has made me hungry!
