In what ways can a non-programmer effectively troubleshoot and resolve issues with PHP code that is not functioning as expected in a web application?

Issue: One common issue with PHP code in web applications is syntax errors, which can cause the code to not execute properly. To troubleshoot this, carefully review the code for any missing semicolons, parentheses, or curly braces. Additionally, using an online PHP syntax checker can help identify and fix syntax errors.

// Example PHP code snippet with syntax error
<?php
echo "Hello, World!"
?>
```

```php
// Corrected PHP code snippet
<?php
echo "Hello, World!";
?>
