What is the difference between php and go?
This article mainly explains "what is the difference between php and go?". The content of the explanation is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the difference between php and go?"
Bitwise XOR of PHP
The ASCII value of echo "'Y' is:". Ord ('Y'). The ASCII value of PHP_EOL;echo "8 is:". Ord (8). The ASCII value of PHP_EOL;echo "8' is:". Ord ('8'). PHP_EOL;echo "'Y' ^ 8 =". ('Y' ^ 8). PHP_EOL; / / 8echo "'Y' + 8 =". ('Y' + 8). PHP_EOL; / / 8echo "Y' ^'8' =". ('Y' ^'8'). PHP_EOL; / / aecho "89 ^ 8 =". (89 ^ 8). PHP_EOL; / / 81echo "'89'^ 8 =". ('89'^ 8). PHP_EOL / / 8x parsing / / Y ascii 89 ^'8' ascii 56max / 89 ^ 8 = 1011001ax / ^ 000000A / = 1010001 = 64 + 16 + 4 + 1 = 81max / 89 ^ 56 = 1011001Accord / ^ 0111000pm / = 1100001 = 64 + 32 + 1 = 97 = a # the ASCII value of result'Y' is: 568' ASCII value is 'Y' + 8 = 8 years Y'^'8' = a89 ^ 8 = 81'89 ^ 8 = 81
When php is a non-numeric string and integer operation, the value is 0
Bitwise XOR of Go
Func main () {fmt.Println ("'Y' ^ 8 =",'Y' ^ 8) fmt.Println ("'Y' ^'8' =",'Y' ^'8') fmt.Println ("89 ^ 8 =", 89 ^ 8)} # result'Y' ^ 8 = 81 ^ Y' ^ 8' = 9789 ^ 8 = 81
Go is still relatively rigorous, converting rune to corresponding ascii code values for operation.
