怎么将数据库里面内容以不同的颜色显示在页面下

<br />$style = array(0=>"red",1=>"yellow",2=>"gree");<br />根据数据库的值 输出样式<br />

<br />	$ar1=array(0,1,2);<br />	$ar2=array(0,1,2);<br />	$ar3=array(0,1,2);<br />	$ar4=array(0,1,2);<br />	$ar5=array(0,1,2);<br />	$ar6=array(0,1,2);<br />	$ar7=array(0,1,2);<br />	<br /><br /><table border="1" cellspacing="0" cellpadding="0" width="600"><br />	for($i=0;$i<count($ar1);$i++){<br />		echo "<tr>";<br />		echo "<td>".$ar1[$i]."</td>";<br />		echo "<td>".$ar2[$i]."</td>";<br />		echo "</tr>";<br />	}<br /></table><br /><br />

<br /><style type="text/css"><br />.r{<br />background-color:red;<br />}<br />.y{<br />background-color:yellow;<br />}<br />.g{<br />background-color:green;<br />}<br /></style><br /><script src="http://code.jquery.com/jquery-latest.js"></script><br /><script type="text/javascript"><br />	$(function(){<br />		$("#abv").click(function(){<br />			$("tr td").each(function(){<br />				if($(this).text()==0){<br />					$(this).addClass("r");<br />				}else if($(this).text()==1){<br />					$(this).addClass("y");<br />				}else{<br />					$(this).addClass("g");<br />				}<br />			});<br />		});<br />	})<br /> </script><br /><input type="button" id="abv" value="测试用按钮"/><br /><table border="1" cellspacing="0" cellpadding="0" width="600"><br /> <tr><br />	<td/>0</td><br />	<td>2</td><br />	<td>2</td><br />	<td>1</td><br />	<td>2</td><br />	<td>2</td><br />	<td>1</td><br /> </tr><br /> <tr><br />	<td>2</td><br />	<td>2</td><br />	<td>1</td><br />	<td/>1</td><br />	<td>1</td><br />	<td>2</td><br />	<td>0</td><br /> </tr><br /> <tr><br />	<td/>0</td><br />	<td>1</td><br />	<td>2</td><br />	<td/>0</td><br />	<td>1</td><br />	<td>2</td><br />	<td>0</td><br /> </tr><br /></table><br /><br />

<style type="text/css"><br />.col_0 {<br />background-color:red;<br />}<br />.col_1 {<br />background-color:yellow;<br />}<br />.col_2 {<br />background-color:green;<br />}<br /></style>

while($row=mysql_fetch_array($result))<br />{<br />  echo '<tr>';<br />  for($i=0; $i<7; $i++) {<br />    echo "<td class='col_{$row[$i]}'>{$row[$i]}</td>";<br />  }<br />  echo '</tr>';<br />}
