[1]一个显示天气预报的程序
    来源: 互联网  发布时间: 2013-11-30
刚开始学PHP，先编写了一个程序，放在自己的主页上，可以显示天气预报，当然还很不完善，希望大家给提意见。程序如下：
<?
$fcont=file("http://www.bjmb.gov.cn/today.asp");
$arr=array();
for($i=0;$i<count($fcont);$i++){
    $tmp=$fcont[$i];
    $tmp=ereg_replace("<br>"," ",$tmp);
    if(!strstr(strtolower($tmp),"img")){
        $tmp=trim(strip_tags($tmp));
    } else {
        $st=ereg_replace("><",">⌒<",$tmp);
        $stt=split("⌒",$st);
        foreach($stt as $key => $value){
            if(strstr($value,"img") ){
                $tmp=$value;
                $tmp=ereg_replace("src=","width=30 height=30 align=absmiddle src="/blog_article/,$tmp);_br/_                if(strstr($tmp,/index.html"bt9.jpg") || strstr($tmp,"colline.gif")) $tmp="";
            }
        }
    }
    if(trim($tmp)!="" && trim($tmp)!="　") $arr[]=$tmp;
}
$yb=array();
for($i=2;$i<count($arr)-6;$i++){
    $yb[]=$arr[$i];
}
?>
<br>
<SCRIPT LANGUAGE="JavaScript">
<!--
syb="";
<?
$exp="-3-7-9-14-18-20-25-";
for ($i=1;$i<count($yb);$i++){
    if (!strstr($exp,"-".(string)($i+1)."-")){
?>
    syb=syb+'<?=$yb[$i];?> ';
<?}}?>
document.write("<?=$yb[0]?>"+":");
document.write("<marquee width=400 align=middle scrollamount=5 scrolldelay=200>"+syb+"预报</marquee>");
//-->
</SCRIPT>
本来获取的语句只需要执行一次，然后将获取的数据和旧数据比较，是否是新的，如果是新的，替换掉旧数据，否则，不替换。这是有规律可寻的，先判断时间，一般比预报时间晚一个小时的话，肯定可以获取最新的预报数据了。不过现在我没有考虑那么多，以后再说吧！

[3]php中文本数据翻页（留言本翻页）
    来源: 互联网  发布时间: 2013-11-30
在mysq中介绍翻页的文章不少,而文本数据表格式的翻页介绍的很少，这里我就简单的说一下翻页

主要介绍以下翻页思想
1、留言本的翻页
2、文本论坛的翻页

————————————————————————
留言本的翻页：
——————————————————————————————
这个在文本数据表中的翻页是最简单的翻页，这样说明一下

golbal file
    Data.dat    ---    NOTE FILE USE
    user.dat    ---     Forum File use
Data.dat
_______________________________________________________________________
[1]    [POSTUSER]     [TITLE]        [MEM]        [POSTTIME]    [IP]
[2]    [POSTUSER]     [TITLE]        [MEM]        [POSTTIME]    [IP]
[3]    [POSTUSER]     [TITLE]        [MEM]        [POSTTIME]    [IP]
[4]    [POSTUSER]     [TITLE]        [MEM]        [POSTTIME]    [IP]
[5]    [POSTUSER]     [TITLE]        [MEM]        [POSTTIME]    [IP]

说明：
     其中的[1,2,3,4,5....]是我自己添加进去的，主要是为了大家更好的理解

index.php source:.

写的仓促，另外中间有不少因为考虑到使用PHP4.20所以就改变了一下，比如说PHP_SELF已经采用_SERVER["PHP_SELF"]等
