Avoid using characters like (0,o,O,1,i,l) in generating random passwords.
<?php
function randomPassword($length = 6) {
// Non-ambiguous chars
$alphabet = 'ABCDEFGHJKLMNPQRSTUVWXYZ23456789';
$alphamax = strlen($alphabet) - 1;
$password = '';
for ($i = 0; $i < $length; $i++) {
$password .= $alphabet[mt_rand(0, $alphamax)];
}

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;
}

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';
