Why is the value of a variable more important than its name in PHP functions?

The value of a variable is more important than its name in PHP functions because functions operate on the values passed to them, not the variable names. As long as the value passed to a function is correct, the function will work as intended regardless of the variable name. It is crucial to ensure that the correct values are passed to functions to achieve the desired outcome.

// Example of passing values to a function
function addNumbers($num1, $num2) {
    return $num1 + $num2;
}

$number1 = 5;
$number2 = 10;

$result = addNumbers($number1, $number2);
echo $result; // Output: 15
