PHP While Loops

The idea of a loop is to do something over and over again until the task has been completed.
In PHP, we have the following looping statements:
  • while - loops through a block of code while a specified condition is true
  • do...while - loops through a block of code once, and then repeats the loop as long as a 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 while loop executes a block of code while a condition is true.

Syntax

1

    while (condition)
    {
    code to be executed;
    }
The do...while statement will always execute the block of code once, it will then check the condition, and repeat the loop while the condition is true.
