How can unexpected parse errors be resolved in PHP scripts?

Unexpected parse errors in PHP scripts can be resolved by carefully reviewing the code for syntax errors, such as missing semicolons, parentheses, or curly braces. Additionally, using a code editor with syntax highlighting can help identify any mistakes. Finally, running the script through a PHP syntax checker can pinpoint the exact location of the error.

<?php
// Example code snippet with a missing semicolon causing a parse error
echo "Hello, World" // missing semicolon here
?>
```

To resolve the parse error in the code snippet above, simply add a semicolon at the end of the `echo` statement like this:

```php
<?php
// Fixing the missing semicolon to resolve the parse error
echo "Hello, World"; // semicolon added here
?>
