ExpertCodingMaster.Com: While loop in Php

While loops are used to execute a block of code again and again until a specified condition is true.
In while loop at first initialisation is done. In initialisation we assign any value to a variable.

<?php
/* suppose we want to print 1-20 */
$i = 1; // initialisation of varable
while($i<=20)
{
echo $i . "<br>";
$i++;
}
?>
</body>
</html>
