hongster / Unicode Hexadecimal To UTF-8 String Conversion

Created March 23, 2015 06:40

Combine hex-to-string function with encoding conversion. In this example, the source string Unicode string encoded in hexadeciaml. The following code decodes it and convert it to UTF-8 string.

	<?php
	function hexToStr($hex){
	$string='';
	for ($i=0; $i < strlen($hex)-1; $i+=2){
	$string .= chr(hexdec($hex[$i].$hex[$i+1]));
	}
	return $string;
	}

	$s = '6df157335e0253575c71533a53576d7759279053003100300037003953f7002000200068007400740070003a002f002f007700770077002e006700700073002e0063006f006d002f006d00610070002e0061007300700078003f006c00610074003d00320033002e0031003200330026006c006e0067003d003100310033002e003100320033';

hongster / Change Character Encoding And Represent In Hexadecimal

Last active August 29, 2015 14:17

PHP encodes string in UTF-8. This code converts it to Unicode, and then represent it as hexadecimal.

	<?php
	function strToHex($string){
	$hex = '';
	for ($i=0; $i<strlen($string); $i++){
	$ord = ord($string[$i]);
	$hexCode = dechex($ord);
	$hex .= substr('0'.$hexCode, -2);
	}
	return $hex;
	}
