Integer hech bolmaganda bitta raqamdan tashil topishi.Decimal bolmasligi.
Yuqoridagi namunada "$x" bu integer, PHP var_dump(); funksiya integerga qaytish uchun.
PHP Float namuna:

*- koryapmizki, bu yerda $cars array, chunki array koplab amallardan iborat.
PHP String function:
Funksiya strlen(); dan iborat, yani string+length=strlen
Bu satrni olchamini, undagi belgilar sonini aniqlaydi va ekranga uzatadi:
  1. <?php
