php - Difference between ( $value == 1 ) and ( $value == '1' ) -


मैं 

  के बीच के अंतर को जानना चाहता हूं अगर ($ value == 1 ) {// code}

और 

  यदि ($ value == '1') {// code}

$ मान पूर्णांक है जो मैं डेटाबेस (MySQL) से चयन करता हूं।
अवश्य, मैं इसे डेटाबेस में इंटरगेयर के रूप में सम्मिलित करता हूं।

कोई भी विधि क्षण के लिए सही तरीके से काम करता है, जो अधिक है सही तरीके से?

धन्यवाद।

सबसे सही तरीका है: 

  यदि ($ value === '1')

ऐसा इसलिए है क्योंकि MySQL में सभी (गैर-नल) मान स्ट्रिंग के रूप में लौटाए जाते हैं, क्योंकि यह नुकसान को रोकता है उच्च-सटीक भंडारण के लिए सटीकता की, जैसे कि BIGINT को 32-बिट प्रक्रिया, या निश्चित-बिंदु वास्तविक संख्या में भेजा जा रहा है।

हालांकि, आपको सबसे अधिक संभावना है: 

  यदि ($ value == 1)

वास्तव में, कौन परवाह करता है?

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
