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 方式一：header("Location: index.php"); 方式二：echo "<script>window.location =/"$PHP_SELF/";</script>"; 方式三：echo "<META HTTP-EQUIV=/"Refresh/" CONTENT=/"0; URL=index.php/">"; 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<=7; $i++) { if (strpos($Agent,$Browsers[$i])) { $browser = $Browsers[$i]; $browserver =""; } } if (ereg("Mozilla",$Agent) && !ereg("MSIE",$Agent)) { $temp =explode("(", $Agent); $Part=$temp[0]; $temp =explode("/", $Part); $browserver=$temp[1]; $temp =explode(" ",$browserver); $browserver=$temp[0]; $browserver =preg_replace("/([/d/.]+)/","//1",$browserver); $browserver = " $browserver"; $browser = "Netscape Navigator"; } if (ereg("Mozilla",$Agent) && ereg("Opera",$Agent)) { $temp =explode("(", $Agent); $Part=$temp[1]; $temp =explode(")", $Part); $browserver=$temp[1]; $temp =explode(" ",$browserver);$browserver=$temp[2]; $browserver =preg_replace("/([/d/.]+)/","//1",$browserver); $browserver = " $browserver"; $browser = "Opera"; } if (ereg("Mozilla",$Agent) && ereg("MSIE",$Agent)) { $temp = explode("(", $Agent); $Part=$temp[1]; $temp = explode(";",$Part); $Part=$temp[1]; $temp = explode(" ",$Part);$browserver=$temp[2]; $browserver =preg_replace("/([/d/.]+)/","//1",$browserver); $browserver = " $browserver"; $browser = "Internet Explorer"; } if ($browser!="") { $browseinfo = "$browser$browserver"; } else { $browseinfo = "Unknown"; } return $browseinfo; } //调用方式$browser=browseinfo() ;直接返回结果 3、获取访问者操作系统 function osinfo() { $os=""; $Agent = $GLOBALS["HTTP_USER_AGENT"]; if (eregi(\\\'win\\\',$Agent) && strpos($Agent, \\\'95\\\')) { $os="Windows 95"; } elseif (eregi(\\\'win 9x\\\',$Agent) && strpos($Agent, \\\'4.90\\\')) { $os="Windows ME"; } elseif (eregi(\\\'win\\\',$Agent) && ereg(\\\'98\\\',$Agent)) { $os="Windows 98"; } elseif (eregi(\\\'win\\\',$Agent) && eregi(\\\'nt 5/.0\\\',$Agent)) { $os="Windows 2000"; } elseif (eregi(\\\'win\\\',$Agent) && eregi(\\\'nt\\\',$Agent)) { $os="Windows NT"; } elseif (eregi(\\\'win\\\',$Agent) && eregi(\\\'nt 5/.1\\\',$Agent)) { $os="Windows XP"; } elseif (eregi(\\\'win\\\',$Agent) && ereg(\\\'32\\\',$Agent)) { $os="Windows 32"; } elseif (eregi(\\\'linux\\\',$Agent)) { $os="Linux"; } elseif (eregi(\\\'unix\\\',$Agent)) { $os="Unix"; } elseif (eregi(\\\'sun\\\',$Agent) && eregi(\\\'os\\\',$Agent)) { $os="SunOS"; } elseif (eregi(\\\'ibm\\\',$Agent) && eregi(\\\'os\\\',$Agent)) { $os="IBM OS/2"; } elseif (eregi(\\\'Mac\\\',$Agent) && eregi(\\\'PC\\\',$Agent)) { $os="Macintosh"; } elseif (eregi(\\\'PowerPC\\\',$Agent)) { $os="PowerPC"; } elseif (eregi(\\\'AIX\\\',$Agent)) { $os="AIX"; } elseif (eregi(\\\'HPUX\\\',$Agent)) { $os="HPUX"; } elseif (eregi(\\\'NetBSD\\\',$Agent)) { $os="NetBSD"; } elseif (eregi(\\\'BSD\\\',$Agent)) { $os="BSD"; } elseif (ereg(\\\'OSF1\\\',$Agent)) { $os="OSF1"; } elseif (ereg(\\\'IRIX\\\',$Agent)) { $os="IRIX"; } elseif (eregi(\\\'FreeBSD\\\',$Agent)) { $os="FreeBSD"; } if ($os==\\\'\\\') $os = "Unknown"; return $os; } //调用方式$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\\\', \\\'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/t"; echo "test2/t/n"; echo "test1/t"; echo "test2/t/n"; echo "test1/t"; echo "test2/t/n"; echo "test1/t"; echo "test2/t/n"; echo "test1/t"; echo "test2/t/n"; echo "test1/t"; echo "test2/t/n"; ?> //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 举一个简朴例子说明:比如一个论坛对当天发表的贴子用new图片标记一下。 方式一： //$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\\\'>":""; 方式二： $newTag=$db->rows[$i][date]>=date("Y-m-d 00:00:00")?"<img src=\\\'../image/newinfor.gif\\\'>":""; 7、PHP中对数据库操作的封装 我的例子.........见上面附件！ 返回类别: 教程 上一教程: 十天学会php之第二天 下一教程: PHP安装攻略:在Windows 9x下的安装和配置 您可以阅读与"经验积累，献给PHP兴趣者！！！"相关的教程: · PHP教程.经验技巧(上) · PHP教程.经验技巧(中) · PHP4实际应用经验篇(1) · PHP4实际应用经验篇(6) · PHP4实际应用经验篇(2) |
