In what ways can a PHP developer improve their code structure and readability by following recommended practices for variable naming and data manipulation functions like explode()?

When it comes to improving code structure and readability in PHP, using meaningful variable names and following recommended practices for data manipulation functions like explode() can make a significant difference. By choosing descriptive variable names, developers can easily understand the purpose of each variable at a glance. Additionally, using explode() with clear delimiter parameters and storing the result in appropriately named variables can enhance code readability and maintainability.

// Original code
$data = "John,Doe,30";
$info = explode(",", $data);
$firstName = $info[0];
