How can PHP beginners effectively utilize the PHP manual for reference?

PHP beginners can effectively utilize the PHP manual for reference by using the search functionality to find specific functions or language constructs, reading through the documentation to understand how they work, and looking at examples provided to see how they are used in practice.

// Example of using the PHP manual to understand the array_map function
$array = [1, 2, 3, 4, 5];
$multiplied_array = array_map(function($value) {
    return $value * 2;
}, $array);
print_r($multiplied_array);
