How can error messages be helpful in debugging PHP code?

Error messages in PHP can be helpful in debugging code by providing specific information about what went wrong, such as syntax errors, undefined variables, or unexpected behaviors. By carefully reading and understanding these error messages, developers can pinpoint the issue and make necessary corrections to their code. Additionally, error messages can help in identifying potential security vulnerabilities and improving the overall quality of the code. Example PHP code snippet: 

```php
<?php
// Example code with a syntax error
$variable = 10
echo $variable;
?>
```

In this example, the error message will indicate that there is a syntax error on line 2 due to the missing semicolon. By adding the semicolon after `$variable = 10;`, the code will execute without any issues.
