最近刚刚完成手中的项目，比较闲。来这儿转转，把积累的一些技巧分享给大家！ 1、关于PHP重定向方法一：header("Location: index.php"); 方法二：echo ""; 方法三：echo ""; 2、获取访问者浏览器 function browse_infor() { $browser="";$browserver=""; $Browsers =array("Lynx","MOSAIC","AOL","Opera","JAVA","MacWeb","WebExplorer","OmniWeb"); $Agent = $GLOBALS["HTTP_USER_AGENT"]; for ($i=0; $i 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, js => application/x-javascript, pdf => application/pdf, ps => application/postscript, eps => application/postscript, ai => application/postscript, wmf => application/x-msmetafile, css => text/css, htm => text/html, html => text/html, txt => text/plain, xml => text/xml, wml => text/wml, wbmp => image/vnd.wap.wbmp, mid => audio/midi, wav => audio/wav, mp3 => audio/mpeg, mp2 => audio/mpeg, avi => video/x-msvideo, mpeg => video/mpeg, mpg => video/mpeg, qt => video/quicktime, mov => video/quicktime, lha => application/x-lha, lzh => application/x-lha, z => application/x-compress, gtar => application/x-gtar, gz => application/x-gzip, gzip => application/x-gzip, tgz => application/x-gzip, tar => application/x-tar, bz2 => application/bzip2, zip => application/zip, arj => application/x-arj, rar => application/x-rar-compressed, hqx => application/mac-binhex40, sit => application/x-stuffit, bin => application/x-macbinary, uu => text/x-uuencode, uue => text/x-uuencode, latex=> application/x-latex, ltx => application/x-latex, tcl => application/x-tcl, pgp => application/pgp, asc => application/pgp, exe => application/x-msdownload, doc => application/msword, rtf => application/rtf, xls => application/vnd.ms-excel, ppt => application/vnd.ms-powerpoint, mdb => application/x-msaccess, wri => application/x-mswrite, ); 5、php生成excel文档 header("Content-type:application/vnd.ms-excel"); header("Content-Disposition:filename=test.xls"); echo "test1 "; echo "test2 "; echo "test1 "; echo "test2 "; echo "test1 "; echo "test2 "; echo "test1 "; echo "test2 "; echo "test1 "; echo "test2 "; echo "test1 "; echo "test2 "; ?> //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?"
