Chr (), UNICHR () and Ord ()The CHR () function returns a corresponding character by using an integer (that is, 0~255) within range (256) as a parameter. UNICHR () is just like it, except that the Unicode character is returned, and the parameter range of the UNICHR () added from Python 2.0 depends on how your Python is compiled. If it is configured to USC2 Unicode, then it is allowed to range (65536) or 0X0000-0XFFFF, if configured as UCS4, then this

Park,unpark,ord These 3 functions, in our work, they are not much estimated. In my most recent job, because communication requires a binary stream, the interface is received in PHP. At that time, a lot of information was consulted. Because they are less used, and few friends use them in their work. At work, I've come to understand that Park,unpark,ord is powerful for binary byte processing. Let me introduce
At work, I gradually learned that park, unpark, and ord are powerful in processing binary bytes. Next I will introduce them one by one. The three functions park, unpark, and ord are not used much in our work. In my recent work, binary stream is used for communication, and the interface is received in php. At that time, I checked a lot of materials. Because they are rarely used, and few friends will use them
Chr (), unichr (), and ord ()
The chr () function uses a range (0 to 256 ~ 255) an integer is used as a parameter and a corresponding character is returned. Unichr () is the same as it, but only returns Unicode characters. The parameter range of unichr () added from Python 2.0 depends on how your Python is compiled. If Unicode is configured as USC2, the allowed range is range (65536) or 0x0000-0xFFFF. If it is configured as UCS4, the value should be r

In php, ord intercepts Chinese strings and solves garbled characters. In the following two examples, we use ord to identify the ascii characters of the instance to refer to www.111cn for Chinese garbled characters. netphperphp4103 below we give two examples are the use of ord instance character ascii judgment to encourage the emergence of Chinese garbled problem,

DescribeThe Ord () function is the Chr () function (for 8-bit ASCII strings) or the UNICHR () function (for Unicode objects), which returns the corresponding ASCII value, or Unicode value, as a parameter with a character (a string of length 1). If the given Unicode character exceeds your Python definition range, a TypeError exception is thrown.GrammarThe following is the syntax for the Ord () method:Ord (c)

Chr function is used to convert ASCII code to characters
The ORD function is used to convert characters to ASCII code
ASCII code is the computer can display the character of the code, its value range is 0-255, including punctuation, letters, numbers, Chinese characters and so on. In the programming process, the specified characters are often converted to ASCII code for comparison.
Below is a PHP-supplied function that converts ASCII code and chara
Php intercepts Chinese strings without garbled characters (ord (), substr () function)
This article introduces two functions in php that intercept Chinese strings without garbled characters, namely the ord () function and substr () function. For more information, see.Note in php Programming: according to the UTF-8 coding specification, count three consecutive characters as a single character.Let's

This article provides a detailed analysis of how to use the pack, unpack, and ord functions of binary stream interface application instances. For more information, see pack, unpack and ord are powerful in processing binary bytes. Next I will introduce them one by one. In our work, we do not have much estimation to use them.

The ord function is used to convert characters into ASCII codes.
ASCII code is the encoding of characters that can be displayed by a computer. Its value ranges from 0 to 255, including punctuation, letters, numbers, and Chinese characters. During programming, the specified characters are often converted into ASCII codes for comparison.

At work, I also learned that Pack,unpack,ord is powerful for binary byte processing. Let me introduce them to you. In our work, there is not much estimation of their use. I am in a recent job, because the communication needs to use the binary stream, and then the interface is received in PHP. At that time, a lot of information was consulted. Because they are really less used, they are seldom used by friends in their work. At work, I also learned that

The problem with Ord ()
The manual says that it is converted to ASCII, but ASCII has only 127 characters. Why does Ord ("I") still be able to output the results?
------Solution--------------------
Who tell U ASCII only 127?
Plus the extension should have 256.
Ord () is the conversion of the first character of a string into an ASCII code. Chinese is a double
