There are 3 types of loop in PHP: while (condition) { code_goes_here; } do { code_goes_here; } while (condition); for(expr1, expr2, expr3) { code_goes_here; } In terms of the ‘for’ loop above, ‘expr1’ being the starting expression, i.e. $i=0. expr2 being the condition that must be satisfied to keep the loop running, i.e. $i < 100. expr3 being the expression evaluated each time the loop runs, i.e. $i++.

The important point being that all strings remain intact: […]
