How to use while loop in PHP
In this article, I will explain how the while loop can be used in PHP.
while Loop in PHP
-
The while loop executes a block of code while a condition is true.
-
The while statement is simple, it executes the statement repeatedly as long as the end of condition.
-
In the while loop, condition is checked every time at the beginning of the loop.
Syntax
|
while (condition)
{
code to be executed;
}
|
When the condition is true then the code block will be executed. After the code has executed the condition will again be evaluated and the loop will continue until the condition is found to be false.
Example
The following example show a loop that starts with a=1. The loop will continue to run as long as a is less than, or equal to 10. I will increase by 1 each time the loop runs.
