htmlentities in PHP but preserving html tags
You can get the list of correspondances character => entity used by htmlentities
, with the function get_html_translation_table
; consider this code :
$list = get_html_translation_table(HTML_ENTITIES);var_dump($list);
(You might want to check the second parameter to that function in the manual -- maybe you'll need to set it to a value different than the default one)
It will get you something like this :
array ' ' => string ' ' (length=6) '¡' => string '¡' (length=7) '¢' => string '¢' (length=6) '£' => string '£' (length=7) '¤' => string '¤' (length=8) .... .... .... 'ÿ' => string 'ÿ' (length=6) '"' => string '"' (length=6) '<' => string '<' (length=4) '>' => string '>' (length=4) '&' => string '&' (length=5)
Now, remove the correspondances you don't want :
unset($list['"']);unset($list['<']);unset($list['>']);unset($list['&']);
Your list, now, has all the correspondances character => entity used by htmlentites, except the few characters you don't want to encode.
And now, you just have to extract the list of keys and values :
$search = array_keys($list);$values = array_values($list);
And, finally, you can use str_replace to do the replacement :
$str_in = '<p><font style="color:#FF0000">Camión español</font></p>';$str_out = str_replace($search, $values, $str_in);var_dump($str_out);
And you get :
string '<p><font style="color:#FF0000">Camión español</font></p>' (length=84)
Which looks like what you wanted ;-)
Edit : well, except for the encoding problem (damn UTF-8, I suppose -- I'm trying to find a solution for that, and will edit again)
Second edit couple of minutes after : it seem you'll have to use utf8_encode
on the $search
list, before calling str_replace
:-(
Which means using something like this :
$search = array_map('utf8_encode', $search);
Between the call to array_keys
and the call to str_replace
.
And, this time, you should really get what you wanted :
string '<p><font style="color:#FF0000">Camión español</font></p>' (length=70)
And here is the full portion of code :
$list = get_html_translation_table(HTML_ENTITIES);unset($list['"']);unset($list['<']);unset($list['>']);unset($list['&']);$search = array_keys($list);$values = array_values($list);$search = array_map('utf8_encode', $search);$str_in = '<p><font style="color:#FF0000">Camión español</font></p>';$str_out = str_replace($search, $values, $str_in);var_dump($str_in, $str_out);
And the full output :
string '<p><font style="color:#FF0000">Camión español</font></p>' (length=58)string '<p><font style="color:#FF0000">Camión español</font></p>' (length=70)
This time, it should be ok ^^
It doesn't really fit in one line, is might not be the most optimized solution ; but it should work fine, and has the advantage of allowing you to add/remove any correspondance character => entity you need or not.
Have fun !
Might not be terribly efficient, but it works
$sample = '<p><font style="color:#FF0000">Camión español</font></p>';echo htmlspecialchars_decode( htmlentities($sample, ENT_NOQUOTES, 'UTF-8', false) , ENT_NOQUOTES);
This is optimized version of the accepted answer.
$list = get_html_translation_table(HTML_ENTITIES);unset($list['"']);unset($list['<']);unset($list['>']);unset($list['&']);$string = strtr($string, $list);
