Ta’rif va qo‘llanilishi
current() funksiyasi massivdagi joriy elementning qiymatini qaytaradi.
Har bir massivda o‘zining "joriy" elementiga ishora qiluvchi ichki ko‘rsatkich bo‘ladi; u dastlab massivga qo‘shilgan birinchi elementga o‘rnatiladi.
Maslahat: Bu funksiya massivning ichki ko‘rsatkichini siljitmaydi.
Tegishli metodlar:
- end() - ichki ko‘rsatkichni massivdagi oxirgi elementga siljitadi va uni chiqaradi
- next() - ichki ko‘rsatkichni massivdagi keyingi elementga siljitadi va uni chiqaradi
- prev() - ichki ko‘rsatkichni massivdagi oldingi elementga siljitadi va uni chiqaradi
- reset() - ichki ko‘rsatkichni massivning birinchi elementiga siljitadi
- each() - joriy elementning kaliti va qiymatini qaytaradi hamda ichki ko‘rsatkichni oldinga siljitadi
