利用static实现表格的颜色隔行显示

我们用PHP从数据库查询数据,并将结果输出到浏览器上,如果结果有很多行,表格的bgcolor如果全是单色的,浏览者会感觉不太舒服。那麽怎样做使表格各行的颜色不同呢?
请看下面:

function getcolor()
{
static $colorvalue;//定义一个静态变量
if($colorvalue=="#ffffff")
$colorvalue="#000000";
else $colorvalue="#ffffff";
return($colorvalue);
}

print("

n");//下面输出10行
for($i=0;$i{ $bcolor=getcolor();//换背景颜色
print("n");
print("n");
print("");
}
print("
$i
n");
说明:
此程序中定义了一个静态变量static $colorvalue意思是在函数调用结束后,
此变量$colorvalue还保留值,没有消失。当再次调用getcolor()函数时,变量$colorvalue的值是上次函数调用结束时$colorvalue的值。
