What are the best practices for avoiding numbered variables in PHP code?

Avoiding numbered variables in PHP code is important for code readability and maintainability. Instead of using numbered variables like $var1, $var2, etc., it is recommended to use descriptive variable names that indicate the purpose of the variable. This makes the code easier to understand for both the original developer and anyone who may need to work on the code in the future. Example: 

// Bad practice: using numbered variables
$var1 = 'foo';
$var2 = 'bar';

// Good practice: using descriptive variable names
$firstVariable = 'foo';
$secondVariable = 'bar';
