The parameters can be given an index with the <literal>=></literal> operator. Read the section on the <link linkend="language.types.array">array type</link> for more information on what an array is. </para> <para> <note> <para> <function>array</function> is a language construct used to represent literal arrays, and not a regular function. </para> </note> </para> <para> Syntax "index => values", separated by commas, define index and values. index may be of type string or numeric. When index is omitted, a integer index is automatically generated, starting at 0. If index is an integer, next generated index will be the biggest integer index + 1. Note that when two identical index are defined, the last overwrite the first. </para> <para> The following example demonstrates how to create a two-dimensional array, how to specify keys for associative arrays, and how to skip-and-continue numeric indices in normal arrays. <example> <title><function>array</function> example</title> <programlisting role="php"> <![CDATA[ <?php $fruits = array ( "fruits" => array ("a"=>"orange", "b"=>"banana", "c"=>"apple"), "numbers" => array (1, 2, 3, 4, 5, 6), "holes" => array ("first", 5 => "second", "third") ) ?> ]]> </programlisting> </example> </para> <para> <example> <title>Automatic index with <function>array</function></title> <programlisting role="php"> <![CDATA[ <?php $array = array( 1, 1, 1, 1, 1, 8=>1, 4=>1, 19, 3=>13); print_r($array); ?> ]]> </programlisting> <para> will display : <screen role="php"> <![CDATA[ Array ( [0] => 1 [1] => 1 [2] => 1 [3] => 13 [4] => 1 [8] => 1 [9] => 19 ) ]]> </screen> </para> </example> Note that index '3' is defined twice, and keep its final value of 13. Index 4 is defined after index 8, and next generated index (value 19) is 9, since biggest index was 8. </para> <para> This example creates a 1-based array. <example> <title>1-based index with <function>array</function></title> <programlisting role="php"> <![CDATA[ <?php $firstquarter = array(1 => 'January', 'February', 'March'); print_r($firstquarter); ?> ]]> </programlisting> <para> will display : <screen> <![CDATA[ Array ( [1] => January [2] => February [3] => March ) ]]> </screen> </para> </example> </para> <para> See also <function>array_pad</function>, <function>list</function>, <link linkend="control-structures.foreach">foreach</link>, 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 -->
