    <para>
     <function>html_entity_decode</function> er det modsatte af
     <function>htmlentities</function>, da den konverterer alle HTML-entiteter
     til deres anvendelige tegn fra <parameter>string</parameter>.
    </para>
    <para>
     Den valgfrie anden <parameter>quote_style</parameter>-parameter lader dig
     definere hvad der skal gøres med 'enkelte' og "dobbelte" citationstegn.
     Den tager en af tre konstanter med <constant>ENT_COMPAT</constant> som
     standard:
     <table>
      <title>Tilgængelige <parameter>quote_style</parameter> konstanter</title>
      <tgroup cols="2">
       <thead>
        <row>
         <entry>Konstant Navn</entry>
         <entry>Beskrivelse</entry>
        </row>
       </thead>
       <tbody>
        <row>
         <entry><constant>ENT_COMPAT</constant></entry>
         <entry>Vil konvertere dobbelte citationstegn og lade enkelte
         være.</entry>
        </row>
        <row>
         <entry><constant>ENT_QUOTES</constant></entry>
         <entry>Vil konvertere både dobbelte og enkelte citationstegn.</entry>
        </row>
        <row>
         <entry><constant>ENT_NOQUOTES</constant></entry>
         <entry>Vil lade både dobbelte og enkelte citationstegn være.</entry>
        </row>
       </tbody>
      </tgroup>
     </table>
    </para>
    <para>
     ISO-8859-1 tegnsættet er standardværdi for den valgfrie tredje
     <parameter>charset</parameter>. Denne definerer tegnsættet brugt i
     konverteringen.

    $trans_tbl = array_flip($trans_tbl);
    return strtr($string, $trans_tbl);

     <note>
      <para>
       You might wonder why trim(html_entity_decode('&amp;nbsp;')); doesn't
       reduce the string to an empty string, that's because the '&amp;nbsp;'
       entity is not ASCII code 32 (which is stripped by
       <function>trim</function>) but ASCII code 160 (0xa0) in the default ISO
       8859-1 characterset.
