PHP loops are used to execute the same block of code again and again, as long as a certain condition is true.

In PHP, we have the following loop types:

• while – loops through a block of code as long as the specified condition is true
• do...while – loops through a block of code once, and then repeats the loop as long as the specified condition is true
• for – loops through a block of code a specified number of times
• foreach – loops through a block of code for each element in an array

The following chapters will explain and give examples of each loop type.
