What steps can be taken to troubleshoot and debug PHP code that is producing unexpected errors, such as parse errors or syntax issues?

To troubleshoot and debug PHP code that is producing unexpected errors, such as parse errors or syntax issues, you can start by checking for any syntax errors in your code, such as missing semicolons or parentheses. You can also use a code editor with syntax highlighting to easily spot any errors. Additionally, you can try using an online PHP syntax checker tool to identify and fix any syntax issues in your code.

// Example PHP code snippet with syntax errors
<?php
$name = "John"
echo "Hello, $name!";
?>
```

```php
// Corrected PHP code snippet
<?php
$name = "John";
echo "Hello, $name!";
?>
