Are there any specific characters or symbols that need to be used for line breaks in PHP?

In PHP, the specific character used for line breaks is "\n". This character is used to create a new line in a string, allowing for better formatting and readability. To include line breaks in your PHP code, simply add "\n" wherever you want a new line to start.

// Example of using line breaks in PHP
$text = "This is line 1.\nThis is line 2.";
echo $text;
```

Output:
```
This is line 1.
This is line 2.
