The chr function is used to convert ASCII codes into characters. 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. The following is a function provided by PHP to

Returns a string representing the number of parameters I represent. For example,CHR returns the character "a". the valid range of parameters I is 0 to 1. 111(0x10ffff), the value of the other range throws an exception ValueError. The inverse function of the conversion is Ord (), which converts a string into a numeric value. Examples:#chr () function print (' 0x5a: ',

Copy CodeThe code is as follows: $lenth = 19;$str = "How will the long title of the news show only a few words in front, followed by ..." To replace it? ";echo strlen ($str) ?> Copy the Code code as follows: /*@ Another method, use the Ord () function:@ Applies to gb2312 encoding:*/$str = "How will the long title of the news show only a few words in front, followed by ..." To replace it? ";function Gb2312_substr ($STR, $limit) {$restr = ";for ($i =0; $i $restr. = Ord ($str [$i]) >127?

Why does Str_repeat,str_pad use CHR to return ASCII code in some cryptographic algorithms in PHP? Consider the following encryption algorithm: function Custom_hmac ($algo, $data, $key, $raw _output = False){$algo = Strtolower ($algo);$pack = ' H '. strlen ($algo (' Test '));$size = 64;$opad = Str_repeat (Chr (0x5C), $size);$ipad = Str_repeat (Chr (0x36), $size)

Oracle provides the following explanations for ASCII and CHR functions:ASCII (x) gets the ASCII value of the character X, CHR () and ASCII () have the opposite effect.That is, the ASCII function is used to convert characters into their corresponding ASCII code, while the CHR function is opposite;Here are some simple examples:Select ascii ('x'), ASCII ('y'), ASCII

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 0X00

Use chr($i)The ASCII can be printed smoothly, however, when $i>=19968 (the Unicode starting value of the Chinese character is 4E00 decimal), it is not possible to print out the characters. Such as: Although there are other methods, such as: //代码2$character = html_entity_decode('一', ENT_QUOTES, 'UTF-8'); But why doesn't code 1 print out Chinese characters? Reply content: The use chr($i) can prin
