复制代码 1、关于PHP重定向- 方法一:header("Location: index.php");
- 方法二:echo "<scrīpt>window.location ="$PHP_SELF";</scrīpt>";
- 方法三:echo "<META HTTP-EQUIV="Refresh" CONTENT="0; URL=index.php">";
复制代码 2、获取访问者浏览器- function browse_infor()

3、获取访问者操作系统- function osinfo() {
- $os="";

- }
- if ($os=='') $os = "Unknown";
- return $os;
- }
复制代码 //调用方法$os=os_infor() ;
4、文件格式类- $mime_types = array(
- 'gif' => 'image/gif',
- 'jpg' => 'image/jpeg',
- 'jpeg' => 'image/jpeg',
- 'jpe' => 'image/jpeg',
- 'bmp' => 'image/bmp',
- 'png' => 'image/png',
- 'tif' => 'image/tiff',
- 'tiff' => 'image/tiff',
- 'pict' => 'image/x-pict',
- 'pic' => 'image/x-pict',
- 'pct' => 'image/x-pict',
- 'tif' => 'image/tiff',
- 'tiff' => 'image/tiff',
- 'psd' => 'image/x-photoshop',
- 'swf' => 'application/x-shockwave-flash',

- 'ppt' => 'application/vnd.ms-powerpoint',
- 'mdb' => 'application/x-msaccess',
- 'wri' => 'application/x-mswrite',
- );
复制代码 5、php生成excel文档- <?
- header("Content-type:application/vnd.ms-excel");
- header("Content-Disposition:filename=test.xls");
- echo "test1t";
- echo "test2tn";
- echo "test1t";
- echo "test2tn";
- echo "test1t";
- echo "test2tn";
- echo "test1t";
- echo "test2tn";
- echo "test1t";
- echo "test2tn";
- echo "test1t";
- echo "test2tn";
- ?>
复制代码 //改动相应文件头就可以输出.doc .xls等文件格式了
6、时间比较问题
举一个简单例子说明:比如一个论坛对当天发表的贴子用new图片标记一下。
方法一:- //$db->rows[$i][date]中为数据库中datetime字段值.
- $today=time();
- $theDay=date("Y-m-d H:i:s",$today-24*3600);
- $newTag=$db->rows[$i][date]>=$theDay?"<img src='../image/newinfor.gif'>":"";
复制代码 方法二:- $newTag=$db->rows[$i][date]>=date("Y-m-d 00:00:00")?"<img src='../image/newinfor.gif'>":"";
复制代码 //提取页面和浏览器提交的变量,作用相当于使PHP.INI开了全局变量- @extract($_SERVER, EXTR_SKIP);
- @extract($_SESSION, EXTR_SKIP);
- @extract($_POST, EXTR_SKIP);
- @extract($_FILES, EXTR_SKIP);
- @extract($_GET, EXTR_SKIP);
- @extract($_ENV, EXTR_SKIP);
复制代码 //得到ip地址- $ip=$_SERVER['REMOTE_ADDR'];
- $ip1 = getenv('HTTP_X_FORWARDED_FOR');
- if (($ip1 != "") && ($ip1 != "unknown")) $ip=$ip1;
复制代码 //读取文件函数- function readfromfile($file_name) {
- if (file_exists($file_name)) {
- $filenum=fopen($file_name,"r");
- flock($filenum,LOCK_EX);
- $file_data=fread($filenum, filesize($file_name));
- rewind($filenum);
- fclose($filenum);
- return $file_data;
- }
- }
复制代码 //写入文件函数- function writetofile($file_name,$data,$method="w") {
- $filenum=fopen($file_name,$method);
- flock($filenum,LOCK_EX);
- $file_data=fwrite($filenum,$data);
- fclose($filenum);
- return $file_data;
- }
复制代码 //页面快速转向- function turntopage($url="index.php",$info = "页面转向中...",$second=2){
- print "<html>n<head>n<title>页面转向中....</title>n";
- print "<meta http-equiv="refresh" content="$second;url=$url">n";
- print "<style type="text/css">n<!--n";
- print "td { font-family: "Verdana", "Arial";font-size: 12px}n";
- print "A {COLOR: #000000; TEXT-DECORATION: none}n";
- print "-->n</style>n";
- print "</head>n<body>n";
- print "<table width="100%" border="0" align="center">n";
- print " <tr>n";
- print " <td height="200"> </td>n";
- print " </tr>n";
- print " <tr>n";
- print " <td align="center">n";
- print " <table width="60%" border="0" cellpadding="8" bgcolor="#AA9FFF">n";
- print " <tr>n";
- print " <td height="30" align="center">页面转向提示信息</td>n";
- print " </tr>n";
- print " <tr>n";
- print " <td align="center">$info</td>n";
- print " </tr>n";
- print " <tr>n";
- print " <td align="center">n";
- print " <a href="$url">如果你的浏览器不支持自动跳转,请按这里</a></td>n";
- print " </tr>n";
- print " </tr>n";
- print " </table></td>n";
- print " </tr>n";
- print " <tr>n";
- print " <td height="200"> </td>n";
- print " </tr>n";
- print "</table>n";
- print "</body>n</html>";
- exit;
