经典循环例子

<HTML><HEAD><TITLE>经典循环例子</TITLE></HEAD><BODY><?    for($counter = 1; $counter <= 6; $counter++)        //循环6次    {        print("<B>counter is $counter</B><BR>n");    //打印6次    }    ?></BODY></HTML>

for的高级运用

<HTML><HEAD><TITLE>for的高级运用</TITLE></HEAD><BODY><?    /*     ** 打印必要的说明文字     */    print("<B>距离星期一还有几天?</B>n");    print("<OL>n");    for($currentDate = date("U");          //定义$currentDate时间格式        date("l", $currentDate) != "Monday"; //判断是不是当前系统时间是Monday        $currentDate += (60 * 60 * 24))     //当前时间加上1天    {        /*         ** 打印时间名称         */        print("<LI>" . date("l", $currentDate) . "n");    }    print("</OL>n");?></BODY></HTML>

函数的简单调用:

<HTML><HEAD><TITLE>简单的函数</TITLE></HEAD><BODY><FONT SIZE=5><?    function printBold($inputText)       //定义function printBold()    {        print("<B>" . $inputText . "</B>");   ////打印$inputText    }    print("这行没有加重!<BR>n");         //直接打印字符串    printBold("这行加重了!!!");         //调用function printBold()函数    print("<BR>n");    print("这行没有加重!<BR>n");         //直接打印字符串?></FONT></BODY></HTML>

有返回值的函数

<HTML><HEAD><TITLE>有返回值的函数</TITLE></HEAD><BODY><FONT SIZE=5><?    function makeBold($inputText)    //定义function makeBold()函数    {        $boldedText = "<B>";        $boldedText .= $inputText;        $boldedText .= "</B>";        return($boldedText);        //返回变量$boldedText    }    print("这行没有加重!!!<BR>n");    //直接打印字符串        print(makeBold("这行被加重了!!!") . "<BR>n");
//调用function makeBold()函数    print("这行没有加重!!!<BR>n");    //直接打印字符串?></SIZE></BODY></HTML>
