PHP应用技巧小总结：几个有用的小技巧_[PHP教程]

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 = "browserbrowserver";
}
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',
'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
