What are some tips for debugging PHP code effectively to identify syntax errors?

One tip for debugging PHP code effectively to identify syntax errors is to carefully review the error messages provided by the PHP interpreter. These messages often point to the exact line and character where the syntax error occurred. Another tip is to use a code editor with syntax highlighting to easily spot syntax errors. Additionally, using an online PHP syntax checker tool can help quickly identify and fix syntax errors in your code.

```php
<?php

// Example code snippet with a syntax error
$name = "John";
echo "Hello, $name"

?>
```

In this code snippet, the syntax error is missing a semicolon at the end of the `echo` statement. Adding a semicolon at the end will fix the syntax error.
