What does the placeholder %title represent in PHP code?

The placeholder %title in PHP code is typically used as a placeholder for a variable that will be replaced with a specific value when the code is executed. It is commonly used in functions like sprintf() or printf() where you want to insert a variable value into a string. To use the %title placeholder, you need to provide the actual value that will replace it when the code is executed. This can be done by passing the value as an argument to the function that contains the placeholder. Example PHP code snippet:

```php
$title = "Welcome to our website!";
$message = sprintf("Hello, %title", $title);
echo $message;
```

In this code snippet, the %title placeholder is replaced with the value of the $title variable when the sprintf() function is executed. The output will be "Hello, Welcome to our website!".
