いくつかのPHPアプリケーションスキル

1. PHP リダイレクトについて
1. PHP リダイレクトについて
方法 1: header("Location:index.php");
方法 2: echo "window.location ="$ PHP_SELF" ;";
方法 3: echo "";

2 , Get訪問者のブラウザ
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);
$temp =explode( " ", $browserver); $browserver=$temp[0];
$browserver =preg_replace("/([d.] )/","1",$browserver); ;
$browser = "Netscape Navigator"
}
if (ereg("Mozilla",$Agent) && ereg("Opera",$Agent))
{
$temp =explode("(", $Agent); $Part=$temp[1];
$temp =explode(")", $browserver=$temp[1]; =explode(" ",$browserver);$browserver=$temp[2];
$browserver =preg_replace("/([d.] )/","1",$browserver);ブラウザーバー = " $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;
}
/ /呼び出しメソッド $browser=browseinfo(); 結果を直接返します

3. 訪問者のオペレーティング システムを取得します
関数 osinfo() {
$os=""; ["HTTP_USER_AGENT"];
if (eregi('win',$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('AIX' , $Agent)) {
$os="HPUX";
}
elseif (eregi('NetBSD',$Agent)) {
$os="NetBSD";
elseif (ereg('BSD',$Agent)) {
$os="BSD";
}
elseif (ereg('OSF1',$Agent)) {
$ os ="OSF1";
elseif (ereg('IRIX',$Agent)) {
$os="IRIX";
elseif (ereg('FreeBSD' , $Agent)) {
$os="FreeBSD";
if ($os=='') $os = "不明";
return $os;
//调用メソッド$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' =>
'png' => '画像/png',
'tif' =>'画像/tiff',
'tiff' =>'画像/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' => msmetafile'、

'css'、'text/css'、'
'htm'、'text/html'、'

);
5、php生成excel文档
header("Content-type:application/vnd.ms-excel");
header("Content-Disposition:filename=test.xls");
エコー「test1t」;
エコー「test2tn」;
エコー「test1t」;
エコー「test2tn」;
エコー「test1t」;
エコー「test2tn」;
エコー「test1t」;
エコー「test2tn」;
エコー「test1t」;
エコー「test2tn」;
エコー「test1t」;
エコー「test2tn」;
?>
//変更対応文件头就可出.doc .xls等文件格式了
6、時間比较问题
一例一例说明:比一论坛对当天播表的贴子用新图片标记
方法 1:
//$db->rows[$i][date] はデータベース内の datetime フィールド値です。
$today=time();
$theDay=date("Y-m-d H:i:s",$today-24*3600);
$newTag=$db->rows[$i][date]>=$theDay?"":"";
方法 2:
$newTag=$db->rows[$i][date]>=date("Y-m-d 00:00:00")?"
