PHP Basics – Looping Statements
1.While Loop
<?php
/*
* Author : Anthoniraj
* Created on Jan 8, 2008
* Program Name : 11whileloop.php
*/
//Formal While loop
$x=1;
while ($x<=10)
{
echo “The Value of X is $x <br>”;
$x++;
}
//Alternate Syntax
$z=10;
while ($z>0):
echo “The Value of Z is $z <br>”;
$z–;
endwhile;
?>
2.Do-While Loop
<?php
/*
* Author : Anthoniraj
* Created on Jan 8, 2008
* Program Name : 12dowhile.php
*/
$i=1;
do
{
echo $i;
$i++;
}while($i<=10);
?>
3. For Loop
<?php
/*
* Author : Anthoniraj
* Created on Jan 9, 2008
* Program Name : 13forloop.php
*/
//Normal for loop
echo “The Normal For loop <br>”;
for ($i=0;$i<=5;$i++)
{
echo “$i <br>”;
}
//alternate syntax
echo “The Alternate For loop <br>”;
for ($i=0;$i<=5;$i++) :
echo “$i <br>”;
endfor;
//foreach loop used to iterate only Arrays in PHP
echo “The For Each loop <br>”;
$arr = array(1,2,3,4,5,6);
foreach ($arr as $value)
{
echo “$value <br>”;
}
//another for each loop
$a = array (“x”=>10,”y”=>20,”z”=>30);
foreach ($a as $key => $value)
{
echo “$key => $value <br>”;
}
?>
