Explain working of loops in array.

Answer in Brief

Using Foreach loop:

The foreach statement is used to loop through arrays.
For each pass, the value of the current array element is assigned to $value and the array pointer is moved by one and in the next pass, the next element will be processed.

Example:

<?php
$Student_name = arrayO’Magilan”, “Iniyan”, “Nilani” “Sibi” “Shini”); foreach ($Student_name as $value) { echo “$value <br>”;
}
?>

Using For Loop:

To loop through and print all the values of an indexed array.

Example:

<?php$cars = arrayC’Volvo”, “BMW”, “Toyota”);
$arrlength = count(cars);
for($x = 0; $x < $arrlength; $x++){
echo $cars[$x];
echo “<br>”;
}
?>

What will be displayed in a browser when the following PHP code is executed;

<?php
for ($counter = 10; $counter < 10;
$counter = $counter + 5){
echo “Hello”;
 }
?>

$count=12;
do{
printf(“%d squared=%d<br/>”,
$count, pow($count,2));
} while($count<4);
?>

What will be the output of the code.
