PHP While

WHILE : executes the nested statements repeatedly, as long as the while expression evaluates to true.

FOR: It is used for executing a block of statements repeatedly until a given condition returns false.

do-while : It loops are very similar to while loops, except the truth expression is checked at the end of each iteration instead of in the beginning.

break : It ends execution of the current for, foreach, while, do-while or switch structure.

continues : It skips the current iteration of the loop and continues with the next iteration.
