Warning This extension is deprecated as of PHP 5.5.0, and will be removed in the future. Instead, the MySQLi or PDO_MySQL extension should be used. See also MySQL: choosing an API guide and related FAQ for more information. Alternatives to this function include: omysqli_fetch_row(3) o PDOStatement::fetch array mysql_fetch_row (resource $result) DESCRIPTION
Returns a numerical array that corresponds to the fetched row and moves the internal data pointer ahead. o $ result -The result resource that is being evaluated. This result comes from a call to mysql_query(3).

Example #1 Fetching one row with mysql_fetch_row(3) <?php $result = mysql_query("SELECT id,email FROM people WHERE id = '42'"); if (!$result) { echo 'Could not run query: ' . mysql_error(); exit; } $row = mysql_fetch_row($result); echo $row[0]; // 42 echo $row[1]; // the email value ?> Note This function sets NULL fields to the PHP NULL value. mysql_fetch_array(3), mysql_fetch_assoc(3), mysql_fetch_object(3), mysql_data_seek(3), mysql_fetch_lengths(3), mysql_result(3).
