What best practices should be followed when replacing specific words or phrases in a text with dynamic values in PHP?

When replacing specific words or phrases in a text with dynamic values in PHP, it is best practice to use placeholders or tokens in the original text and then replace them with the dynamic values using PHP's str_replace() function. This approach helps to maintain the original structure of the text and makes it easier to update the dynamic values in the future. 

// Original text with placeholders
$text = "Hello, [name]! Your [product] is ready for pickup.";

// Dynamic values
$name = "John";
$product = "iPhone";

// Replace placeholders with dynamic values
$text = str_replace("[name]", $name, $text);
$text = str_replace("[product]", $product, $text);

echo $text;
