What are the best practices for deleting specific entries (key and value) from a multidimensional array in PHP?

When deleting specific entries (key and value) from a multidimensional array in PHP, you can use the unset() function to remove the specified key and its corresponding value. This function will completely remove the key-value pair from the array, effectively deleting the entry. 

// Sample multidimensional array
$multiArray = array(
    "key1" => array("value1", "value2"),
    "key2" => array("value3", "value4"),
    "key3" => array("value5", "value6")
);

// Deleting a specific entry from the multidimensional array
unset($multiArray["key2"]);

// Output the modified array
print_r($multiArray);
