 Foreach (array_expression as $value){

statement;

}

Foreach (array_expression as $key => $value){

statement;

}

for example

<?php

$arr = array(2,3,4,5) ;

foreach($arr as &$value){

$value = $value * 2;

}

//$arr now is array(4,6,8,10)

unset($value);//break the reference with the last element

//warning Reference of a $value and the last array element remain even after the foreach loop.It is recommended to destroy it by unset().

?>

<?php

$arr = array(”apply “,”orange”,”banana”);

reset($arr); //Set the internal pointer of an array to its first element

foreach($arr as $key => $value){

echo “Key:$key;Value:$value<br />\n”;

}

?>
