In PHP, how do I deep copy strings with SPL?

To deep copy strings in PHP using the Standard PHP Library (SPL), you can create a function that clones the string into a new variable. However, since strings are immutable in PHP, the deep copy is simply done by assigning the string to a new variable.

Here’s an example of how to do this:


        <?php
        // Original string
        $originalString = "Hello, World!";
        
        // Deep copy the string
        $deepCopiedString = $originalString;
        
        // Modifying the deep copied string
        $deepCopiedString .= " How are you?";
        
        echo "Original String: " . $originalString . "<br>";
        echo "Deep Copied String: " . $deepCopiedString;
        ?>
