PHP 中的一些經驗積累

作者:snowai 

最近剛剛完成手中的項目,比較閑。來這兒轉轉,把積累的一些技巧分享給大傢!
1、關於php(做為現在的主流開發語言)重定向
方法一:header(“Location: index.php(做為現在的主流開發語言)“);
方法二:echo “<script>window.location =”$php(做為現在的主流開發語言)_SELF”;</script>”;
方法三:echo “<META HTTP-EQUIV=”Refresh” CONTENT=”0; URL=index.php(做為現在的主流開發語言)“>”;

2、獲取訪問者瀏覽器

<P class=php(做為現在的主流開發語言)>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 $browseinfo;
}
//調用方法$browser=browseinfo() ;直接返回結果



3、獲取訪問者操作系統
<P class=php(做為現在的主流開發語言)>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 $os;
}
//調用方法$os=os_infor() ;

);


5、php(做為現在的主流開發語言)生成excel文檔 <P class=php(做為現在的主流開發語言)>
<?
header(“Content-type:application/vnd.ms-excel”);
header(“Content-Disposition:filename=test.xls”);
echo “test1 “;
echo “test2
“;
echo “test1
