Coder Therapy Session 43: Debugging the Unreliable Sock Drawer

Welcome to Coder Therapy Session 43! Today, we're tackling the age-old problem of debugging the Unreliable Sock Drawer.

We've got a special guest, a brilliant but slightly unhinged programmer who's been wrestling with this issue for weeks. Let's get into it.

Case Study: Unreliable Sock Drawer

The Unreliable Sock Drawer is a notorious bug that's been causing chaos in our client's laundry room. Here's the code snippet responsible:

        
            <?php
                // Initialize sock drawer state
                $socks = array();

                // Iterate over sock drawer
                foreach ($socks as $sock) {
                    // Check if sock is matching pair
                    if ($sock == $sock) {
                        // Add to matching pair list
                        $matching_socks[] = $sock;
                    }
                }

                // Print matching socks
                echo implode(' ', $matching_socks);
            ?>
        
    

What's the problem with this code?

• Is this a infinite loop?
• Is this code trying to match socks by name, not by color?
• Is this code trying to match socks by... self?
