   read.

      <para>
       Must be greater than the longest line (in characters) to be found in
       the CSV file (allowing for trailing line-end characters). Otherwise the
       line is split in chunks of <parameter>length</parameter> characters,
       unless the split would occur inside an enclosure.
      </para>
      <para>
       Omitting this parameter (or setting it to 0 in PHP
       5.1.0 and later) the maximum line length is not limited, which is
       slightly slower.

       The optional <parameter>escape</parameter> parameter sets the escape character (one character only).
      </para>
      <note>
       <simpara>
        Usually an <parameter>enclosure</parameter> character is escpaped inside
        a field by doubling it; however, the <parameter>escape</parameter>
        character can be used as an alternative. So for the default parameter
        values <literal>""</literal> and <literal>\"</literal> have the same
        meaning. Other than allowing to escape the
        <parameter>enclosure</parameter> character the
        <parameter>escape</parameter> character has no special meaning; it isn't
        even meant to escape itself.
