If <parameter>pad_size</parameter> is positive then the array is padded on the right, if it's negative then on the left. If the absolute value of <parameter>pad_size</parameter> is less than or equal to the length of the <parameter>input</parameter> then no padding takes place. It is possible to add most 1048576 elements at a time. </para> <para> <example> <title><function>array_pad</function> example</title> <programlisting role="php"> <![CDATA[ <?php $input = array(12, 10, 9); $result = array_pad($input, 5, 0); // result is array(12, 10, 9, 0, 0) $result = array_pad($input, -7, -1); // result is array(-1, -1, -1, -1, 12, 10, 9) $result = array_pad($input, 2, "noop"); // not padded ?> ]]> </programlisting> </example> </para> <para> See also <function>array_fill</function> and <function>range</function>. </para> </refsect1> </refentry> <!-- Keep this comment at the end of the file Local variables: mode: sgml sgml-omittag:t sgml-shorttag:t sgml-minimize-attributes:nil sgml-always-quote-attributes:t sgml-indent-step:1 sgml-indent-data:t indent-tabs-mode:nil sgml-parent-document:nil sgml-default-dtd-file:"../../../../manual.ced" sgml-exposed-tags:nil sgml-local-catalogs:nil sgml-local-ecat-files:nil End: vim600: syn=xml fen fdm=syntax fdl=2 si vim: et tw=78 syn=sgml vi: ts=1 sw=1 -->
