PHP Tutorial » PHP Loops While
In this chapter you will learn how to repeat the code using loops in PHP.
PHP loop
Often, when writing code, you want the same block of code to be run multiple times, a certain number of times. So instead of adding more or less nearly identical lines of code to a script, we can use loops.

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 types of loop:

while - loop a block of code as long as the specified condition is true
do ... while - execute the command once, then repeat the loop as long as the specified condition is true
for - loops through a block of code a specified number
foreach - loops through a block of code for each element in an array

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

Syntax
while (state is true) {
code to execute;
}



Example explained:
$x = 1; - Initialize the loop counter ($ x) and set the start value to 1
$x <= 5 - Continue the loop as long as x is less than or equal to 5
$x ++; - Increase the value of the loop counter by 1 for each iteration
