Not many people know what a disk defrag is; as a matter of fact most people who own a computer have no it is. This article is written to help you figure out how to run a disk defrag so that you can get your computer running as efficiently as possible.
While is some Looping statements in PHP
The while statement will execute a block of code if and as long as a condition is true.
while (condition)
{code to be executed;}
The following example demonstrates a loop that will continue to run as long as the variable i is less than, or equal to 5. i will increase by 1 each time the loop runs:
<html>
<body>
<?php
$i=1;
while($i<=5)
{
echo “The number is ” . “$i” . “<br />”;
$i++;
}
?>
</body>
</html>
And output is
The number is 1
The number is 2
The number is 3
The number is 4
The number is 5
