What are some best practices for referencing PHP documentation when unsure about a function?

When unsure about a PHP function, it is best practice to refer to the official PHP documentation. The PHP manual provides detailed information about each function, including its parameters, return values, and examples of usage. By consulting the documentation, you can ensure that you are using the function correctly and effectively in your code. 

// Example of referencing PHP documentation for the 'strpos' function
$haystack = 'Hello, World!';
$needle = 'World';
$position = strpos($haystack, $needle);
if ($position !== false) {
    echo "The needle was found at position: $position";
} else {
    echo "The needle was not found in the haystack";
}
