Geri JaxpTree nesne. Ağaç gibi ilişki aşağıdaki iç içe bir ağaca MySQL ile ilgili tablo çifti dönüştürmek gerekiyordu:

Ben ek ebeveyn referans (italik satırına bakınız) ile nesneyi döndürmek için çalıştığınızda, ben sonsuz özyineleme döngü ve PHP çöker yakalanmayın.

Ben burada yanlış Nereye gidiyorum?
