How can the EVA principle be applied to improve efficiency in PHP code for data processing and output?

Issue: The EVA principle (Eliminate, Simplify, Automate) can be applied to improve efficiency in PHP code for data processing and output by identifying unnecessary code, simplifying complex logic, and automating repetitive tasks. PHP Code Snippet: 

// Eliminate unnecessary code
// Before: $result = $db->query("SELECT * FROM users WHERE status = 'active'");
// After: $result = $db->query("SELECT name, email FROM users WHERE status = 'active'");

// Simplify complex logic
// Before: if ($status == 'active' && $role == 'admin' && $department == 'IT') { ... }
// After: if ($status == 'active' && $role == 'admin') { ... }

// Automate repetitive tasks
// Before: foreach ($data as $row) { echo $row['name'] . ' - ' . $row['email']; }
// After: foreach ($data as $row) { echo "{$row['name']} - {$row['email']}"; }
