In PHP, how do I deep copy strings for production systems?

In PHP, to deep copy strings, you can simply assign the string to a new variable since strings are immutable in PHP. However, if you need to ensure that complex objects or arrays are deep copied, you may use serialization or other techniques. Below is an example of deep copying a string.


        <?php
        // Original string
        $originalString = "Hello, World!";
        
        // Deep copy of the string
        $copiedString = $originalString;
        
        // Modify the copied string
        $copiedString .= " How are you?";
        
        // Display both strings
        echo "Original String: " . $originalString . "<br>";
        echo "Copied String: " . $copiedString;    
        ?>
