- do-while loops are very similar to while loops, except the truth expression is checked at the end of each iteration instead of in the beginning.
- In PHP do-while is used to provide a control condition.
- In do-while the block of code executed once and then condition is evaluated. If the condition is true, the statement is repeated as long as the specified condition is true.
