What do you mean by looping? …

A loop is a statement that repeats over and over, while a certain condition is true. Or, to state it another way, it runs until a condition is false. A condition is the value or state you are testing. For example, if you want to repeat the same math program 50,000 times, you can write a loop that runs until it has processed 50,000 times.

Loops in PHP are used to execute the same block of code a specified number of times. PHP supports following four loop types.

• for − loops through a block of code a specified number of times.

• while − loops through a block of code if and as long as a specified condition is true.

• do...while − loops through a block of code once, and then repeats the loop as long as a special condition is true.

• foreach − loops through a block of code for each element in an array.
