PHP话语在MYSQL中查询多张表 并显示在页面上

PHP语句在MYSQL中查询多张表 并显示在页面上
用PHP语句实现查询多张表 表的字段是相同的、表名不同。例如：
           abc201202,abc201203,abc201204...表名按月建的表
我新手不知道怎么一次遍历多张表，提取MYSQL中的数据。    
------解决思路----------------------

<br />$table = array("abc201202","abc201203","abc201204");<br />$result =array();<br />foreach($table as $table_name) {<br />      $sql = "select * from ".$table_name;<br />      $rec =mysql_query($sql);<br />      while($row=mysql_fetch_row($rec)) {<br />           $result[] = $row;<br />      }<br />}<br />

------解决思路----------------------

<br /><br />$select = array();<br />$table = array("abc201202","abc201203","abc201204");<br />foreach($table as $v) {<br />   $select[] = "(select * from $v)";<br />}<br /><br />$sql = join(' UNION ', $select);<br />$res = mysql_query($sql);<br /><br />

------解决思路----------------------

<br />$table = array("abc201202","abc201203","abc201204");<br />$result=array();<br />$count = count($table)-1;//减去一个数组下标<br />for ($i=0;$i<$count;$i++){<br />      $sql = $sql." select * from '".$table[$i]."' union all";<br />}<br />$sql=$sql." select * from '".$table[$count]."'";<br />$rec =mysql_query($sql);<br />      while($row=mysql_fetch_row($rec)) {<br />           $result[] = $row;<br />      }<br />
