Foreach loop through multidimensional array in PHP

Use the PHP nested loop

You can simply use the foreach loop in combination with the for loop to access and retrieve all the keys, elements or values inside a multidimensional array in PHP.

Let's take a look at the following example to understand how it basically works:

<?php
// Multidimensional array
$superheroes = array(
    "spider-man" => array(
        "name" => "Peter Parker",
        "email" => "[email protected]",
    ),
    "super-man" => array(
        "name" => "Clark Kent",
        "email" => "[email protected]",
    ),
    "iron-man" => array(
        "name" => "Harry Potter",
        "email" => "[email protected]",
    )
);
 
// Printing all the keys and values one by one
$keys = array_keys($superheroes);
for($i = 0; $i < count($superheroes); $i++) {
    echo $keys[$i] . "{<br>";
    foreach($superheroes[$keys[$i]] as $key => $value) {
        echo $key . " : " . $value . "<br>";
    }
    echo "}<br>";
}
?>
