What are some best practices for structuring PHP code to avoid syntax errors like "unexpected end of file"?

To avoid syntax errors like "unexpected end of file" in PHP, it is important to properly structure your code by ensuring that all opening braces ({) have a corresponding closing brace (}) and that all control structures (if statements, loops, etc.) are properly closed. Additionally, using an integrated development environment (IDE) with syntax highlighting can help identify missing or misplaced braces. Example PHP code snippet:

<?php

// Incorrect code with missing closing brace
if ($condition) {
    echo "Condition is true";
```

Corrected PHP code snippet:
```php
<?php

// Corrected code with proper closing brace
if ($condition) {
    echo "Condition is true";
}
