Core PHP: The while Loop (5.4)

Loops

When writing code, you may want the same block of code to run over and over again. Instead of adding several almost equal code-lines in a script, we can use loops to perform a task like this.

The while Loop

The while loop executes a block of code as long as the specified condition is true.
Syntax:

while (condition is true) {
   code to be executed;
}

If the condition never becomes false, the statement will continue to execute indefinitely.
