Are there any best practices for efficiently removing specific entries from multidimensional arrays in PHP?

When removing specific entries from multidimensional arrays in PHP, one efficient approach is to use a combination of array_filter() and array_map() functions. The array_filter() function can be used to filter out the entries that need to be removed based on a specified condition, and then array_map() can be used to reindex the array if needed. 

// Sample multidimensional array
$multiArray = [
    ['id' => 1, 'name' => 'John'],
    ['id' => 2, 'name' => 'Jane'],
    ['id' => 3, 'name' => 'Alice'],
];

// Remove entry with id 2
$removeId = 2;

// Filter out the entry with specified id
$filteredArray = array_filter($multiArray, function($entry) use ($removeId) {
    return $entry['id'] != $removeId;
});

// Reindex the array if needed
$filteredArray = array_values($filteredArray);

// Output the updated array
print_r($filteredArray);
