这样的两个话语能否结合为一句

这样的两个语句能否结合为一句。

$get_rows = mysql_num_rows("select id from news where class_type='类别'");<br /><br />if($get_rows){<br />  $get_list=mysql_fetch_array("select * from news where class_type='类别'");<br />  .......循环显示<br />}

------解决思路----------------------
很遗憾，非但不能合并为一句，相反要分作三句

$rs = mysql_query("select id from news where class_type='类别'");<br />if($get_rows = mysql_num_rows($rs)) {<br />  $get_list = mysql_fetch_array($rs);<br />  .......循环显示<br />}

------解决思路----------------------

<br />$rs = mysql_query("select id from news where class_type='类别'");<br /><br />$get_list = array();<br /><br />while($row = mysql_fetch_array($rs) ){<br />    array_push($get_list, $row['id']);<br />}<br />$get_rows = count($get_list);<br />
