What is the significance of variable naming conventions in PHP, and how can they impact code functionality?

Variable naming conventions in PHP are significant for code readability and maintainability. Consistent naming conventions help developers easily understand the purpose of variables and make the code more organized. Inconsistent or unclear variable names can lead to confusion and errors in the code. By following a naming convention, such as using camelCase or snake_case, developers can improve the overall quality of their code. 

// Bad variable naming
$var = 10;
$myvariable = "Hello";

// Good variable naming
$myVar = 10;
$myVariable = "Hello";
