PHP Html_entity_decode () turns HTML entities into character prototypes

PHP Html_entity_decode () applies to PHP 4.3.0+, which converts HTML entities into characters.

Html_entity_decode (a string containing an HTML entity, optionally how to decode quotes, optional character encoding sets)

If the string contains a character set that cannot be recognized, it is ignored and replaced by Iso-8859-1. You can use PHP htmlentities () to convert HTML tags, quotes, and other strings outside of the ASCII character set to HTML entities.

How to decode quotes:

Ent_compat-Default. Decodes only double quotes.

Ent_quotes-decodes double quotes and single quotes.

Ent_noquotes-does not decode any quotes.

Character encoding set:

Iso-8859-1-Default. Western europe.

Iso-8859-15-Western Europe (add Euro symbols and French, Finnish letters).

UTF-8-ASCII compatible Multi-byte 8-bit Unicode

Cp866-dos dedicated Cyrillic Character Set

Cp1251-windows dedicated Cyrillic Character Set

PHP Html_entity_decode () turns all HTML entities into character prototypes
PHP Html_entity_decode () instance

Although using PHP htmlentities () can only be HTML materialized for HTML tag strings, you can use PHP Html_entity_decode () to convert all HTML-materialized characters to characters.

<?php   
function ShowCode ($s) {return str_replace (' & ', ' &amp; ', $s);}   
Since the output is still the original character after being converted into an HTML entity, the & is replaced with &amp; You can output the source code

format, and if you don't use this replacement, you can see the same result by looking at the output $html source code.   
       
$weigeti = '--> ' e.v-get.com ' <--';   
       
$html = Htmlentities ($weigeti, ent_quotes);   
       
echo ShowCode ($html);   
Output "--&gt;&quot; e.v-get.com&quot;&lt;--"   
       
$entity = Html_entity_decode ($html);   
echo ShowCode ($entity);   
Output "-->" e.v-get.com "<--"   
       
$entity _noquotes=html_entity_decode ($html, ent_noquotes);   
Echo ShowCode ($entity _noquotes);   
Output "-->&quot; e.v-get.com&quot;<--"   
?>
