西安网站建设--西安做网站的几个PHP小技巧

1、关于PHP重定向

方法一:header("Location:index.php");

方法二:echo"<script>window.location=\"$PHP_SELF\";</script>";

方法三:echo"<METAHTTP-EQUIV=\"Refresh\"CONTENT=\"0;URL=index.php\">";


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<=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="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,'4.90')){

$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();

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";

?>

//只要改动对应文件头就可以输出.doc.xls等文件的格式了
