一个颜色轮换的简单例子,使用三元运算子,使程序简练。
我们曾经在网站上看过一些表格单元格的背景颜色是隔行变化的,其实用下面一段很小的一段代码就可以实现:
$color=(($coloralter++ %2)? e0e0e0:e8e8e8)
,即通过将变量累加和2取余,运用三元运算子来取得两个不同得颜色值。
示例如下: html head titletest/title meta content=text/html;
charset=gb2312 /head body bgcolor=#FFFFFF table width=750 border=0
cellspacing=1 cellpadding=1 ?php for ($i=0;$i5;$i++) { $color =
(($coloralternator++ %2) ? e0e0e0 : ff6666); echo tr
bgcolor=’.$color.’td大家好/td/tr; } ? /table /body /html

//此页面为php3.php ? include signup/mysql.inc; switch($part){ case 1
:$table=bbs_php;break; case 2 :$table=bbs_mysql;break; case 3
:$table=bbs_html;break; case 4 :$table=bbs_js; } //echo $part; ? html
