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

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
