PHP 独特的语法混合了C、Java、Perl以及PHP自创的语法。它可以比CGI或者Perl更快速地执行动态网页。下面就来和大家说说几个php技巧吧。
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<=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 $browseinfo;
//调用方法$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',

'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',

'eps' => 'application/postscript',
'ai' => 'application/postscript',
'wmf' => 'application/x-msmetafile',
'css' => 'text/css',
'htm' => 'text/html',
'html' => 'text/html',

'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
