note 58442 added to function.utf8-encode

I was searching for a function similar to Javascript's unescape(). In most cases it is OK to use url_decode() function but not if you've got UTF characters in the strings. They are converted into %uXXXX entities that url_decode() cannot handle. I googled the net and found a function which actualy converts these entities into HTML entities (&#xxx;) that your browser can show correctly. If you're OK with that, the function can be found here: http://pure-essence.net/stuff/code/utf8RawUrlDecode.phps But it was not OK with me because I needed a string in my charset to make some comparations and other stuff. So I have modified the above function and in conjuction with code2utf() function mentioned in some other note here, I have managed to achieve my goal: <?php /** * Function converts an Javascript escaped string back into a string with specified charset (default is UTF-8). * Modified function from http://pure-essence.net/stuff/code/utf8RawUrlDecode.phps * * @param string $source escaped with Javascript's escape() function * @param string $iconv_to destination character set will be used as second paramether in the iconv function. Default is UTF-8. * @return string */ function unescape($source, $iconv_to = 'UTF-8') { $decodedStr = ''; $pos = 0; $len = strlen ($source); while ($pos < $len) { $charAt = substr ($source, $pos, 1); if ($charAt == '%') { $pos++; $charAt = substr ($source, $pos, 1); if ($charAt == 'u') { // we got a unicode character $pos++; $unicodeHexVal = substr ($source, $pos, 4); $unicode = hexdec ($unicodeHexVal); $decodedStr .= code2utf($unicode); $pos += 4; } else { // we have an escaped ascii character $hexVal = substr ($source, $pos, 2); $decodedStr .= chr (hexdec ($hexVal)); $pos += 2; } } else { $decodedStr .= $charAt; $pos++; } } if ($iconv_to != "UTF-8") { $decodedStr = iconv("UTF-8", $iconv_to, $decodedStr); } return $decodedStr; } /** * Function coverts number of utf char into that character. * Function taken from: http://sk2.php.net/manual/en/function.utf8-encode.php#49336 * * @param int $num * @return utf8char */ function code2utf($num){ if($num<128)return chr($num); if($num<2048)return chr(($num>>6)+192).chr(($num&63)+128); if($num<65536)return chr(($num>>12)+224).chr((($num>>6)&63)+128).chr(($num&63)+128); if($num<2097152)return chr(($num>>18)+240).chr((($num>>12)&63)+128).chr((($num>>6)&63)+128) .chr(($num&63)+128); return ''; } ?> ---- Manual Page -- http://www.php.net/manual/en/function.utf8-encode.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+58442 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+58442&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+58442&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+58442&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+58442&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+58442&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+58442&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+58442&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+58442&report=yes Search -- http://master.php.net/manage/user-notes.php
