It only returns an associative array. This is the way <function>mysql_fetch_array</function> originally worked. If you need the numeric indices as well as the associative, use <function>mysql_fetch_array</function>. </para> <para> If two or more columns of the result have the same field names, the last column will take precedence. To access the other column(s) of the same name, you either need to access the result with numeric indices by using <function>mysql_fetch_row</function> or add alias names. See the example at the <function>mysql_fetch_array</function> description about aliases. </para> <para> An important thing to note is that using <function>mysql_fetch_assoc</function> is <emphasis>not significantly</emphasis> slower than using <function>mysql_fetch_row</function>, while it provides a significant added value. </para> <example> <title>An expanded <function>mysql_fetch_assoc</function> example</title> <programlisting role="php"> <![CDATA[ <?php $conn = mysql_connect("localhost", "mysql_user", "mysql_password"); if (!$conn) { echo "Unable to connect to DB: " . mysql_error(); exit; } if (!mysql_select_db("mydbname")) { echo "Unable to select mydbname: " . mysql_error(); exit; } $sql = "SELECT id as userid, fullname, userstatus FROM sometable WHERE userstatus = 1"; $result = mysql_query($sql); if (!$result) { echo "Could not successfully run query ($sql) from DB: " . mysql_error(); exit; } if (mysql_num_rows($result) == 0) { echo "No rows found, nothing to print so am exiting"; exit; } // While a row of data exists, put that row in $row as an associative array // Note: If you're expecting just one row, no need to use a loop // Note: If you put extract($row); inside the following loop, you'll // then create $userid, $fullname, and $userstatus while ($row = mysql_fetch_assoc($result)) { echo $row["userid"]; echo $row["fullname"]; echo $row["userstatus"]; } mysql_free_result($result); ?> ]]> </programlisting> </example> <para> See also <function>mysql_fetch_row</function>, <function>mysql_fetch_array</function>, <function>mysql_query</function>, and <function>mysql_error</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 -->
