How can debugging techniques in PHP help identify syntax errors and improve code readability?

Debugging techniques in PHP can help identify syntax errors by providing error messages that point to the specific line where the issue occurs. This can help developers quickly locate and fix errors in their code. Additionally, debugging tools like Xdebug can provide detailed information about variables and function calls, helping to improve code readability by allowing developers to better understand how their code is executing. Example:

<?php

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

?>
```

To fix the syntax error in the code above, we need to add a semicolon at the end of the `$name` assignment line:

```php
<?php

// Fixed code with added semicolon
$name = "John";
echo "Hello, $name!";

?>
