What are some best practices for naming variables when working with arrays in PHP?

When working with arrays in PHP, it is important to use clear and descriptive variable names to improve code readability and maintainability. Variable names should indicate the purpose or content of the array, avoiding generic names like $arr or $data. Use camelCase or snake_case naming conventions for variables to enhance clarity. 

// Example of naming variables when working with arrays in PHP
$userList = ['John', 'Jane', 'Alice', 'Bob']; // Good variable name indicating the content of the array

// Avoid using generic variable names like $arr or $data
$names = ['John', 'Jane', 'Alice', 'Bob']; // Unclear variable name that does not indicate the content of the array
