The most common task with arrays is to do something with every element—for instance, sending mail to each element of an array of addresses, updating each file in an array of filenames, or adding up each element of an array of prices. There are several ways to traverse arrays in PHP, and the one you choose will depend on your data and the task you’re performing.
Example:-
<!DOCTYPE html>
<html>
<body>
<?php
$array = array("Lux","Sampoo");
foreach($array as $value) {
print " $value";
}
?>
</body>
</html>Output:-
Lux Shampoo
Example:-
<!DOCTYPE html>
<html>
<body>
<?php
$fnames = ["Amit", "Rahul", "Vijay", "Ravi", "Roshan"];
$arrObject = new ArrayObject($fnames);
$arrayIterator = $arrObject->getIterator();
while( $arrayIterator->valid() ){
echo $arrayIterator->current() . "<br />";
$arrayIterator->next();
}
?>
</body>
</html>Output:-
