How can using English variable and function names improve code readability and maintainability in PHP?

Using English variable and function names can improve code readability and maintainability in PHP by making the code easier to understand for other developers. When variable names are descriptive and in English, it becomes clearer what each variable represents, leading to easier troubleshooting and debugging. Additionally, using English function names can make the purpose of each function more apparent, aiding in the overall comprehension of the codebase. 

// Bad example with non-descriptive variable names
$a = 5;
$b = 10;

function calc($x, $y) {
    return $x + $y;
}

// Good example with descriptive English variable and function names
$firstNumber = 5;
$secondNumber = 10;

function calculateSum($num1, $num2) {
    return $num1 + $num2;
}
