What role does proper syntax, such as including semicolons, play in preventing white screen errors in PHP scripts?

Proper syntax, including using semicolons at the end of each statement, is crucial in preventing white screen errors in PHP scripts. Missing semicolons can cause PHP to interpret code incorrectly, leading to syntax errors that result in a blank white screen. By ensuring that all statements are properly terminated with semicolons, you can avoid these errors and ensure that your PHP script runs smoothly.

<?php

// Incorrect code with missing semicolons causing white screen error
$variable1 = "Hello"
$variable2 = "World"

echo $variable1 . " " . $variable2;

?>
```

```php
<?php

// Corrected code with semicolons added to prevent white screen error
$variable1 = "Hello";
$variable2 = "World";

echo $variable1 . " " . $variable2;

?>
