PHP While Loop Statements

What is While Structure?

Explanation

While structure is another type of loop statements, where the condition is checked at first, the iteration will not stop even if the value changes while executing statements.

Syntax:


while(expr)
{Statements}//true

If the "expr" is true the statements are executed

Multiple statements can be combined using an alternate syntax

Syntax:


while(expr)
{Statements}//true
endwhile;

Example :


<?php
$c=1;
while ($c<=5)
{
echo $c;
$c++;
}
?>
Result :

12345

In the above example the "while" structure displays the numbers from 1 to 5.
