What is the purpose of applying stripslashes to a textarea input in PHP?

When submitting form data through a textarea input in PHP, the data may contain backslashes (\) due to escaping characters. This can cause issues when displaying or processing the input, as the backslashes may be visible or affect the functionality of the application. To resolve this, we can use the stripslashes() function in PHP to remove the backslashes from the textarea input before using it in our application. 

// Example of applying stripslashes to a textarea input in PHP
$text = $_POST['textarea_input']; // Get the textarea input from the form submission
$clean_text = stripslashes($text); // Remove backslashes from the textarea input
// Now $clean_text can be safely used in the application without any backslashes
