How can the variable assignment $text = $endausgabe; help in ensuring that text is progressively modified when replacing words in PHP?

When replacing words in PHP, it is important to ensure that the changes are applied progressively to the original text. By assigning the current state of the text to a new variable before making any modifications, you can maintain the original text while updating the new variable with each change. This ensures that each replacement is applied to the updated text, rather than the original text.

$text = "This is a sample text to demonstrate word replacement.";
$endausgabe = $text;

// Make word replacements
$endausgabe = str_replace("sample", "modified", $endausgabe);
$endausgabe = str_replace("text", "content", $endausgabe);

echo $endausgabe;
