What are the potential pitfalls of using numerical values as variables in PHP code?

Using numerical values as variables in PHP code can lead to confusion and make the code harder to read and maintain. It is best practice to use descriptive variable names that convey the purpose of the value being stored. This makes the code more understandable for yourself and others who may work on it in the future. 

// Bad practice: using numerical values as variables
$var1 = 10;
$var2 = 20;

// Good practice: using descriptive variable names
$firstNumber = 10;
$secondNumber = 20;
