文章内容PHP中的一些经验积累修改时间:[2008/09/0820:30]阅读次数:[528]发表者:[起缘]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:");方法二:echo"=\"$PHP_SELF\";/script方法三:echo"METAHTTP-EQUIV="Refresh"CONTENT="0;URL="2、获取访问者浏览器functionbrowse_infor(){$browser="";$browserver="";$Browsers=array("Lynx","MOSAIC","AOL","Opera","JAVA","MacWeb","WebExplorer","OmniWeb");$Agent=$GLOBALS["HTTP_USER_AGENT"];for($i=0;$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="NetscapeNavigator";}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="InternetExplorer";}if($browser!=""){$browseinfo="$browser$browserver";}else{$browseinfo="Unknown";}return$browseinfo;}//调用方法$browser=browseinfo();直接返回结果3、获取访问者操作系统functionosinfo(){$os="";$Agent=$GLOBALS["HTTP_USER_AGENT"];if(eregi(win,$Agent)&&strpos($Agent,95)){$os="Windows95";}elseif(eregi(win9x,$Agent)&&strpos($Agent,)){$os="WindowsME";}elseif(eregi(win,$Agent)&&ereg(98,$Agent)){$os="Windows98";}elseif(eregi(win,$Agent)&&eregi(nt5\.0,$Agent)){$os="Windows2000";}elseif(eregi(win,$Agent)&&eregi(nt,$Agent)){$os="WindowsNT";}elseif(eregi(win,$Agent)&&eregi(nt5\.1,$Agent)){$os="WindowsXP";}elseif(eregi(win,$Agent)&&ereg(32,$Agent)){$os="Windows32";}elseif(eregi(linux,$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)){$os="IBMOS/2";}elseif(eregi(Mac,$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$mime_types=array(gif=>image/gif,jpg=>image/jpeg,jpeg=>image/jpeg,jpe=>image/jpeg,bmp=>image/bmp,png=>image/png,tif=>image/tiff,tiff=>image/tiff,pict=>image/x-pict,pic=>image/x-pict,pct=>image/x-pict,tif=>image/tiff,tiff=>image/tiff,psd=>image/x-photoshop,swf=>application/x-shockwave-flash,js=>application/x-javascript,pdf=>application/pdf,ps=>application/postscript,eps=>application/postscript,ai=>application/postscript,wmf=>application/x-msmetafile,css=>text/css,htm=>text/html,html=>text/html,txt=>text/plain,xml=>text/xml,wml=>text/wml,wbmp=>image/,mid=>audio/midi,wav=>audio/wav,mp3=>audio/mpeg,mp2=>audio/mpeg,avi=>video/x-msvideo,mpeg=>video/mpeg,mpg=>video/mpeg,qt=>video/quicktime,mov=>video/quicktime,lha=>application/x-lha,lzh=>application/x-lha,z=>application/x-compress,gtar=>application/x-gtar,gz=>application/x-gzip,gzip=>application/x-gzip,tgz=>application/x-gzip,tar=>application/x-tar,bz2=>application/bzip2,zip=>application/zip,arj=>application/x-arj,rar=>application/x-rar-compressed,hqx=>application/mac-binhex40,sit=>application/x-stuffit,bin=>application/x-macbinary,uu=>text/x-uuencode,uue=>text/x-uuencode,latex=>application/x-latex,ltx=>application/x-latex,tcl=>application/x-tcl,pgp=>application/pgp,asc=>application/pgp,exe=>application/x-msdownload,doc=>application/msword,rtf=>application/rtf,xls=>application/,ppt=>application/,mdb=>application/x-msaccess,wri=>application/x-mswrite,);5、php生成excel文档header("Content-type:application/");header("Content-Disposition:filename=");echo"test1\t";echo"test2\t";echo"test1\t";echo"test2\t";echo"test1\t";echo"test2\t";echo"test1\t";echo"test2\t";echo"test1\t";echo"test2\t";echo"test1\t";echo"test2\t";>//改动相应文件头就可以输出.等文件格式了6、时间比较问题举一个简单例子说明:比如一个论坛对当天发表的贴子用new图片标记一下。 方法一://$db->rows[$i][date]中为数据库中datetime字段值.$today=time();$theDay=date("Y-m-dH:i:s",$today-24*3600);$newTag=$db->rows[$i][date]>=$theDay"":"";方法二:$newTag=$db->rows[$i][date]>=date("Y-m-d00:00:00")"":"";7、PHP中对数据库操作的封装我的例子.........见本文附件!PHP中对数据库操作的封装的例子。
