သင်ကိုယ်တိုင်စမ်းကြည့်ပါ

ဥပမာရှင်းလင်းချက်:

gettype() function သည်ကွဲပြားသော variable အမျိုးအစားများ (အရေးပါသောအချက်, string, string, string, string, array နှင့် boolean) ကိုစစ်ဆေးရန်အသုံးပြုသည်။ ဥပမာအားဖြင့်, ကိန်းရှင် variable ကို $a , gettype($a) string "integer" ကိုပြန်ပို့လိမ့်မည်။ Floating Point Variable အတွက် $b သည် string variable ကို $c အတွက် "double" variable "string" အတွက်ပြန်လာလိမ့်မည်။ အကယ်. Variable သည် PHP 7.2 နှင့်နောက်ပိုင်းတွင် gettype() "resource (closed)" နှင့်အစောပိုင်းဗားရှင်းများ၌ "unknown type" ပြန်ပို့နိုင်သည်။
