PHP Loops
Programs often need to do the same job many times: print every item in a list, or keep counting until a limit is reached. Instead of copying the code, you wrap it in a loop, and PHP runs it repeatedly for as long as a condition holds.
PHP offers four kinds of loop:
while- checks a condition first and keeps running the code while that condition stays truedo...while- runs the code one time without checking, then keeps repeating it while the condition stays truefor- repeats the code a set number of timesforeach- runs the code once for every element of an array
Each of these has its own lesson next, with working examples.
