Note that the keys are used in the comparison unlike in <function>array_intersect</function>. </simpara> <para> <example> <title><function>array_intersect_assoc</function> example</title> <programlisting role="php"> <![CDATA[ <?php $array1 = array ("a" => "green", "b" => "brown", "c" => "blue", "red"); $array2 = array ("a" => "green", "yellow", "red"); $result_array = array_intersect_assoc ($array1, $array2); /* $result_array will look like: Array ( [a] => green ) */ ?> ]]> </programlisting> </example> </para> <simpara> In our example you see that only the pair <literal>"a" => "green"</literal> is present in both arrays and thus is returned. The value <literal>"red"</literal> is not returned because in <varname>$array1</varname> it's key is <literal>2</literal> while the key of "red" in <varname>$array2</varname> it is <literal>1</literal>. </simpara> <simpara> The two values from the <literal>key => value</literal> pairs are considered equal only if <literal>(string) $elem1 === (string) $elem2 </literal>. In otherwords a strict type check is executed so the string representation must be the same. <!-- TODO: example of it... --> </simpara> <simpara> See also <function>array_diff</function> and <function>array_intersect</function>. </simpara> </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 --> -- PHP Documentation Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
