怎样利用PHP将从数据库中读取的数据保存再变量中？
利用echo $myrow1[xm_name];可以输出项目名称，利用echo $myrow2[zf];可以得到项目的总分，可是如何在php中将其保存在变量中呢？$xm_name=$myrow1[xm_name];和$xm_zf=$myrow2[zf];两句中变量echo后无结果。
$query1=mssql_query("select * from tb_xm where xm_pcid='$xmpc_id'"); <br>
while($myrow1=mssql_fetch_assoc($query1)){<br>
echo $myrow1[xm_name];<br>
$xm_name=$myrow1[xm_name];/***************/<br>
$query2=mssql_query("select sum(xmpf_small_zf) as zf from tb_xmpf where xmpf_xm='$myrow1[xm_name]'"); <br>
//echo $query2;<br>
echo "总分：";<br>
while($myrow2=mssql_fetch_assoc($query2)){<br>
echo $myrow2[zf];<br>
$xm_zf=$myrow2[zf];<br>
}<br>
