သင်ကိုယ်တိုင်စမ်းကြည့်ပါ

ဥပမာရှင်းလင်းချက်:

PHP တွင် Boolean Value သည် string တွင်နံပါတ်များပါ true သည့်တိုင် "32" သည်ကိန်းအမျိုးအစားတစ်ခုမဟုတ်ပါ။ ဒါကြောင့် $d အတွက်စစ်ဆေးမှုများနှင့် $e FALSE ပြန်လာလိမ့်မည်။ အလားတူပင် $f သည် string တစ်ခုဖြစ်ပြီး၎င်း၏အကြောင်းအရာသည် "null" ဖြစ်သော်လည်း၎င်းသည်ကိန်းဂဏန်းအမျိုးအစား FALSE , Floating Point နံပါတ်များသည် $c ကဲ့သို့သောကိန်းဂဏန်းများ FALSE သိသာထင်ရှားသည့် is_int($c) မဟုတ်ပါ,
