More precisely, this function decodes all the entities (including all numeric entities) that a) are necessarily valid for the chosen document type — i.e., for XML, this function does not decode named entities that might be defined in some DTD — and b) whose character or characters are in the coded character set associated with the chosen encoding and are permitted in the chosen document type. All other entities are left as is. Parameters ¶ string The input string. flags A bitmask of one or more of the following flags, which specify how to handle quotes and which document type to use. The default is ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401 . Available flags constants Constant Name Description ENT_COMPAT Will convert double-quotes and leave single-quotes alone. ENT_QUOTES Will convert both double and single quotes. ENT_NOQUOTES Will leave both double and single quotes unconverted. ENT_SUBSTITUTE Replace invalid code unit sequences with a Unicode Replacement Character U+FFFD (UTF-8) or � (otherwise) instead of returning an empty string. ENT_HTML401 Handle code as HTML 4.01. ENT_XML1 Handle code as XML 1. ENT_XHTML Handle code as XHTML. ENT_HTML5 Handle code as HTML 5. encoding An optional argument defining the encoding used when converting characters. If omitted, encoding defaults to the value of the default_charset configuration option. Although this argument is technically optional, you are highly encouraged to specify the correct value for your code if the default_charset configuration option may be set incorrectly for the given input. The following character sets are supported: Supported charsets Charset Aliases Description ISO-8859-1 ISO8859-1 Western European, Latin-1. ISO-8859-5 ISO8859-5 Little used cyrillic charset (Latin/Cyrillic). ISO-8859-15 ISO8859-15 Western European, Latin-9. Adds the Euro sign, French and Finnish letters missing in Latin-1 (ISO-8859-1). UTF-8 ASCII compatible multi-byte 8-bit Unicode. cp866 ibm866, 866 DOS-specific Cyrillic charset. cp1251 Windows-1251, win-1251, 1251 Windows-specific Cyrillic charset. cp1252 Windows-1252, 1252 Windows specific charset for Western European. KOI8-R koi8-ru, koi8r Russian. BIG5 950 Traditional Chinese, mainly used in Taiwan. GB2312 936 Simplified Chinese, national standard character set. BIG5-HKSCS Big5 with Hong Kong extensions, Traditional Chinese. Shift_JIS SJIS, SJIS-win, cp932, 932 Japanese EUC-JP EUCJP, eucJP-win Japanese MacRoman Charset that was used by Mac OS. '' An empty string activates detection from script encoding (Zend multibyte), default_charset and current locale (see nl_langinfo() and setlocale()), in this order. Not recommended. Note: Any other character sets are not recognized. The default encoding will be used instead and a warning will be emitted. Return Values ¶ Returns the decoded string. Changelog ¶ Version Description 8.1.0 flags changed from ENT_COMPAT to ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML401 . 8.0.0 encoding is nullable now.

Notes ¶ Note: You might wonder why trim(html_entity_decode(' ')); doesn't reduce the string to an empty string, that's because the ' ' entity is not ASCII code 32 (which is stripped by trim()) but ASCII code 160 (0xa0) in the default ISO 8859-1 encoding.

It seems that ENT_XML1 and ENT_XHTML are identical when decoding. up down 7aidan at php dot net ¶20 years ago This functionality is now implemented in the PEAR package PHP_Compat.

Requires iconv. function decodeHtmlEnt($str) { $ret = html_entity_decode($str, ENT_COMPAT, 'UTF-8'); $p2 = -1; for(;;) { $p = strpos($ret, '&#', $p2+1); if ($p === FALSE) break; $p2 = strpos($ret, ';', $p); if ($p2 === FALSE) break; if (substr($ret, $p+2, 1) == 'x') $char = hexdec(substr($ret, $p+3, $p2-$p-3)); else $char = intval(substr($ret, $p+2, $p2-$p-2)); //echo "$char\n"; $newchar = iconv( 'UCS-4', 'UTF-8', chr(($char>>24)&0xFF).chr(($char>>16)&0xFF).chr(($char>>8)&0xFF).chr($char&0xFF) ); //echo "$newchar<$p<$p2<<\n"; $ret = substr_replace($ret, $newchar, $p, 1+$p2-$p); $p2 = $p + strlen($newchar); } return $ret; } up down -1Daniel A. ¶7 years ago I wanted to use this function today and I found the documentation, especially about the flags, not particularly helpful. Running the code below, for example, failed because the flag I used was the wrong one... $string = 'Donna's Bakery'; $title = html_entity_decode($string, ENT_HTML401, 'UTF-8'); echo $title; The correct flag to use in this case is ENT_QUOTES. My understanding of the flag to use is the one that would correspond to the expected, converted outcome. So, ENT_QUOTES for a character that would be a single or double quote when converted... and so on.
