php使用while循环和mysql_fetch_array()函数获取(解析)mysql数据

源码如下：

 <?php
 /* by http://www.manongjc.com */
 $conn = @mysql_connect( \"localhost\", \"userName\", \"password\" ) or die( \"Err:Conn\" );

 $rs = @mysql_select_db( \"my_data \", $conn )  or die( \"Err:Db\" );

 $sql = \"select id,first_name from my_table order by first_name\";

 $rs = mysql_query( $sql, $conn );

 while( $row = mysql_fetch_array( $rs ) )
 {
   echo( \"ID: \" . $row[\"id\"] );
   echo( \" - FIRST NAME: \" . $row[\"first_name\"] . \"<br>\" );
 }

 ?>
