How can PHP beginners effectively navigate and manipulate multidimensional arrays?

PHP beginners can effectively navigate and manipulate multidimensional arrays by using nested loops to iterate through the arrays. They can access specific elements by specifying the key of each dimension. Additionally, functions like array_push() and array_pop() can be used to add or remove elements from the arrays. 

// Example of navigating and manipulating a multidimensional array
$students = array(
    "Alice" => array("Math" => 90, "Science" => 85),
    "Bob" => array("Math" => 88, "Science" => 92)
);

// Accessing a specific element
echo $students["Alice"]["Math"]; // Output: 90

// Adding a new student
$students["Charlie"] = array("Math" => 95, "Science" => 87);

// Removing a student
unset($students["Bob"]);
