What is the significance of checking the PHP manual for function capabilities before implementation?

Checking the PHP manual for function capabilities before implementation is significant because it ensures that the function you are using behaves as expected and meets your requirements. It also helps you understand the parameters and return values of the function, which can prevent unexpected behavior in your code. By consulting the manual, you can make informed decisions about which functions to use and how to use them effectively.

// Example of checking the PHP manual for function capabilities before implementation
$number = 10;

// Using the pow function to calculate the square of a number
$square = pow($number, 2);

echo $square;
