How can PHP developers effectively navigate and utilize the PHP manual for reference?

PHP developers can effectively navigate and utilize the PHP manual by using the search functionality to quickly find relevant functions, parameters, and examples. They should also familiarize themselves with the structure of the manual, including the function reference, language reference, and appendices. Additionally, developers can contribute to the manual by providing feedback or corrections to ensure its accuracy and usefulness.

// Example of using the PHP manual to find information on the 'array_map' function
// Search for 'array_map' in the PHP manual to find the function reference page
// Read the description, parameters, return value, and examples to understand how to use 'array_map' effectively
// Implement the function in your code based on the information provided in the manual

$array = [1, 2, 3, 4, 5];
$multipliedArray = array_map(function($value) {
    return $value * 2;
}, $array);

print_r($multipliedArray);
