Example of converting UTF8 binary and plaintext strings using PHP,

This example describes how PHP converts UTF8 binary and plaintext strings. We will share this with you for your reference. The details are as follows:

<? Php/************ this program is compiled by yunke. Take on php software development when you are free. * satisfy the curiosity of new users, look at what the binary of the UTF-8 looks like dropping ***************************/define (" B ", "<br>"); $ a = "FE"; $ a1 = "FF"; $ s = 16; $ e = 2; echo $ s. "hexadecimal ". $. "indicates ". $ e. "in hexadecimal format ". base_convert ($ a, $ s, $ e ). b; echo $ s. "hexadecimal ". $ a1. "indicates ". $ e. "in hexadecimal format ". base_convert ($ a1, $ s, $ e ). b; $ str = "Who are we with computer rr? "; $ Strlen = strlen ($ str); $ n = 0; echo $ str. '(Binary UTF-8 representation ):'. b; $ str_bin = ''; while ($ n <$ strlen) {$ t = ord ($ str [$ n]); $ stra = base_convert ($ t, 10, 2); if (strlen ($ stra) <8) {$ stra = "0 ". $ stra;} $ str_bin. = $ stra; $ n ++;} echo $ str_bin. B; // has been translated as binary $ str_bin = "1110100010101110101000011110011110101110100101111110011010011100101110100110000101110011111001101000100010010001111001001011101110101100111001101001100010 101111111010001011000010000001111011111011110010011111 "; // enter the binary here. The program is encoded as the plaintext output $ chr =''; $ str = ''; for ($ I = 0; $ I <strlen ($ str_bin); $ I ++) {$ chr. = $ str_bin [$ I]; if ($ I + 1) % 8 = 0) {$ str. = chr (base_convert ($ chr, 2, 10); $ chr = NULL;} echo $ str; // The plaintext of the binary UTF8 source code?>

Running result:

In hexadecimal mode, FE is represented as binary mode. In binary mode, FF is represented as binary mode. In binary mode, rr is 1111111016. Who are we? (Binary UTF-8): 1110100010101110101000011110011110101110100101111110011010011100101110100111001001110010111001101000100010010001111001001011101110101100111001101001100010101111111010001011000010000001111011111011110010011111 computers as Who Are We?
