    <simpara>
     Similar to <function>fgets</function> except that
     <function>fgetcsv</function> parses the line it reads for fields
     in <acronym>CSV</acronym> format and returns an array containing
     the fields read.  The optional third <parameter>delimiter</parameter>
     parameter defaults as a comma, and the optional <parameter>enclosure</parameter> 
     defaults as a double quotation mark.  Both <parameter>delimiter</parameter>
     and <parameter>enclosure</parameter> are limited to one character.  If
     either is more than one character, only the first character is used.
    </simpara>
    <note>
     <simpara>
      The <parameter>enclosure</parameter> parameter was added in PHP 4.3.0.
     </simpara>
    </note>
    <simpara>
     The <parameter>handle</parameter> parameter must be a valid file pointer to a file
     successfully opened by <function>fopen</function>,
     <function>popen</function>, or <function>fsockopen</function>.
    </simpara>
    <simpara>
     The <parameter>length</parameter> parameter must be greater than the longest 
     line to be found in the CSV file (allowing for trailing line-end characters).
    </simpara>
    <simpara>
     <function>fgetcsv</function> returns &false; on error, including
     end of file.
    </simpara>
    <note>
     <simpara>
      A blank line in a CSV file will be returned as an array
      comprising a single <type>null</type> field, and will not be treated 
      as an error.
