I am trying to print the contents of a multidimensional array using a while loop. only the word "array" is displayed 4 times on the browser
<?php
$cars = array
(
array("Volvo"),
array("BMW"),
array("Saab"),
array("Land Rover")
);
$i=0;
while ($i < count($cars)) {
$a = $cars[$i];
echo $a ."
";
$i++;
}
?>
