    <para>
     Returns the numeric position of the last occurrence of
     <parameter>needle</parameter> in <parameter>haystack</parameter>.
    </para>

    <para>
      If <parameter>needle</parameter> is not found,
      <function>iconv_strrpos</function> will return &false;.
    </para>

    &return.falseproblem;

    <para>
      If <parameter>haystack</parameter> or <parameter>needle</parameter> is
      not a string, it is converted to a string and applied as the ordinal
      value of a character.
    </para>

    <para>
      In contrast to <function>strpos</function>, the return value of
      <function>iconv_strrpos</function> is the number of characters that
      appear before the needle, rather than the offset in bytes to the
      position where the needle has been found. The characters are counted
      on the basis of the specified character set <parameter>charset</parameter>.
    </para>
      
    <para>
      See also <function>strrpos</function>, <function>iconv_strpos</function>
      and <function>mb_strrpos</function>.
