What is the importance of properly naming variables in PHP coding?

Properly naming variables in PHP coding is important for readability, maintainability, and avoiding errors. Descriptive variable names make it easier for other developers (or even yourself in the future) to understand the purpose of the variable and how it is used in the code. It also helps in debugging and troubleshooting issues. Avoid using vague or generic names like $x or $temp, instead use meaningful names that reflect the purpose of the variable. 

// Bad variable naming
$x = 10;
$temp = "Hello";

// Good variable naming
$age = 25;
$message = "Hello, World!";
