How can one effectively handle multidimensional arrays in PHP to avoid the need for complex variable manipulation?

When working with multidimensional arrays in PHP, it can be challenging to access and manipulate nested values without complex variable manipulation. One way to effectively handle multidimensional arrays is by using foreach loops to iterate through the arrays and access the values directly. This approach simplifies the process and makes it easier to work with nested data structures. 

// Example of handling multidimensional arrays using foreach loop
$multiArray = [
    'first' => [
        'name' => 'John',
        'age' => 30
    ],
    'second' => [
        'name' => 'Jane',
        'age' => 25
    ]
];

foreach ($multiArray as $key => $innerArray) {
    echo $key . ': ' . $innerArray['name'] . ' is ' . $innerArray['age'] . ' years old.' . PHP_EOL;
}
