How can the PHP manual be utilized to better understand function usage in PHP?

To better understand function usage in PHP, the PHP manual can be utilized as a comprehensive resource. By referring to the manual, developers can find detailed information about each function, including its parameters, return values, and usage examples. This can help clarify any confusion and ensure that functions are being used correctly in PHP code. 

```php
// Example of using the PHP manual to understand function usage
// Let's say we want to use the implode() function to concatenate array elements into a string

$array = array('Hello', 'World', '!');
$string = implode(' ', $array); // concatenate array elements with a space separator

echo $string; // Output: Hello World !
```

By looking up the implode() function in the PHP manual, developers can learn about its parameters (delimiter and array), return value (concatenated string), and see examples of how to use it effectively in their code. This can help improve understanding and usage of functions in PHP.
