Ⅰ win2008 iis php 如何開啟壓縮

因為在做一個項目,項目裡面伺服器主要提供數據,但是數據多了文件就大了,比較浪費流量和時間,我們便用Gzip來處理。我在本機上是apache,伺服器上是IIS6.0,用的是php,那麼我就在這里分享一下。

IIS 的 GZIP 壓縮

1.首先備份 IIS 的配置文件, 復制C:.xml到另外的備份文件夾中. C:.xml是 IIS 的核心配置文件,該文件的完整性一但被破壞,IIS 將無法正常運行,嚴重到需要重新安裝系統.

2. 在開始菜單中啟動 Internet 信息服務(IIS)管理器,右鍵點擊「網站」屬性,打開「服務」選項卡,勾選「HTTP 壓縮」的兩個選項。「臨時目錄」和「臨時目錄最大容量」可根據需要自行設置。設置完成後點擊確定。

3. 右鍵點擊「網站」下方的 「Web服務擴展」,添加一個新的Web服務擴展,擴展名填寫為「HTTP Compression」或其他,都可以。「要求的文件」添加:c:windowssystem32inetsrvgzip.dll ,並勾選「設置擴展狀態為允許」,完成後點擊確定。

4.下面的步驟有些復雜,如果沒有確定的把握能理解,最好不要嘗試,右鍵點擊「Internet 信息服務的」「本地計算機」屬性,勾選「允許直接編輯配置資料庫」並確定。

5. 在開始菜單中運行 notepad C:.xml ,打開metabase.xml 文件,請在任何改動前再次確認該文件已經備份。

6. 用文本編輯器打開metabase.xml ,用查找功能找到「IIsCompressionScheme」,共有3處,都在一起,分別是deflate、gzip和 Parameters,deflate也是一種壓縮格式,不過性能上不如gzip。需要修改的是deflate和gzip這兩段,參數基本一樣,都要修改。

HcDynamicCompressionLevel是用來設置壓縮率,默認是0,最高是10。低壓縮級別生成稍大一些的壓縮文件,但對 CPU 和內存資源的總體影響較小。高壓縮級別通常會生成較小的壓縮文件,但會佔用較多的 CPU 時間和內存。有人說設置成9性價比最高。

HcFileExtensions是用來設置壓縮的靜態文件擴展名,默認是htm、html、txt,根據網站的自身情況添加擴展名,最基本的是js、css。添加時注意原有的換行格式。

HcScriptFileExtensions是用來設置壓縮的動態文件擴展名,默認是asp、dll和exe,根據需要自行添加擴展名,無外乎 aspx、php等。可以將這一項的默認刪除留空,這樣所有的動態響應都以壓縮方式發送。另外,還將動態壓縮 HcFileExtensions 中所有未指定的靜態文件類型,並且因此不將它們放入緩存。同樣地,必須將 HcDoDynamicCompression 設置為 true,以進行動態壓縮。

PHP Gzip

/*
*壓縮數據
*/
publicstaticfunctionob_gzip($content)//$content就是要壓縮的頁面內容,或者說餅干原料
{
if(!headers_sent()&&//如果頁面頭部信息還沒有輸出
extension_loaded("zlib")&&//而且zlib擴展已經載入到PHP中
strstr($_SERVER["HTTP_ACCEPT_ENCODING"],"gzip"))//而且瀏覽器說它可以接受GZIP的頁面
{
$content=gzencode($content."OK",9);//此頁已壓縮」的注釋標簽,然後用zlib提供的gzencode()函數執行級別為9的壓縮,這個參數值范圍是0-9,0表示無壓縮,9表示最大壓縮,當然壓縮程度越高越費CPU。

//然後用header()函數給瀏覽器發送一些頭部信息,告訴瀏覽器這個頁面已經用GZIP壓縮過了!
header("Content-Encoding:gzip");
header("Vary:Accept-Encoding");
header("Content-Length:".strlen($content));
}
return$content;//返回壓縮的內容,或者說把壓縮好的餅干送回工作台。
}

Ⅱ 使用phpize建立php擴展,執行make後報錯,錯誤如下,求解

解決方法

下載zlib-1.2.3.tar.gz放在/usr/local目錄下執行以下命令:
tar -zxvf zlib-1.2.3.tar.gz
cd zlib-1.2.3
./configure
vi Makefile
找到 CFLAGS=-O3 -DUSE_MMAP
在後面加入-fPIC,即變成CFLAGS=-O3 -DUSE_MMAP -fPIC
make && make install

然後再進入/usr/local/httpd-2.4.3這個目錄執行下面的語句:
./configure --prefix=/usr/local/apache2 --with-apr=/usr/local/apr/bin/apr-1-config --with-apr-util=/usr/local/apr-util/bin/apu-1-config --with-pcre=/usr/local/pcre/bin/pcre-config --with-zlib-1.2.3=/usr/local/zlib-1.2.3 --enable-so

Ⅲ php安裝的問題,無法載入 mysql 擴展,請檢查 PHP 配置

首先你需要將PHP安裝目錄下的php_mysql.dll和php_mysqli.dll(我的在D:\apptools\php5\ext目錄下)復制到c:\windows\system32目錄下,然後修改php.ini文件(需要放到c:\windows目錄下),關鍵是extension=php_mysql.dll 和extension_dir = "D:/apptools/php5/ext"。
我的配置是這樣的:

[PHP]

;;;;;;;;;;;
; WARNING ;
;;;;;;;;;;;
; This is the default settings file for new PHP installations.
; By default, PHP installs itself with a configuration suitable for
; development purposes, and *NOT* for proction purposes.
; For several security-oriented considerations that should be taken
; before going online with your site, please consult php.ini-recommended
; and http://php.net/manual/en/security.php.

;;;;;;;;;;;;;;;;;;;
; About php.ini ;
;;;;;;;;;;;;;;;;;;;
; This file controls many aspects of PHP's behavior. In order for PHP to
; read it, it must be named 'php.ini'. PHP looks for it in the current
; working directory, in the path designated by the environment variable
; PHPRC, and in the path that was defined in compile time (in that order).
; Under Windows, the compile-time path is the Windows directory. The
; path in which the php.ini file is looked for can be overridden using
; the -c argument in command line mode.
;
; The syntax of the file is extremely simple. Whitespace and Lines
; beginning with a semicolon are silently ignored (as you probably guessed).
; Section headers (e.g. [Foo]) are also silently ignored, even though
; they might mean something in the future.
;
; Directives are specified using the following syntax:
; directive = value
; Directive names are *case sensitive* - foo=bar is different from FOO=bar.
;
; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one
; of the INI constants (On, Off, True, False, Yes, No and None) or an expression
; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").
;
; Expressions in the INI file are limited to bitwise operators and parentheses:
; | bitwise OR
; & bitwise AND
; ~ bitwise NOT
; ! boolean NOT
;
; Boolean flags can be turned on using the values 1, On, True or Yes.
; They can be turned off using the values 0, Off, False or No.
;
; An empty string can be denoted by simply not writing anything after the equal
; sign, or by using the None keyword:
;
; foo = ; sets foo to an empty string
; foo = none ; sets foo to an empty string
; foo = "none" ; sets foo to the string 'none'
;
; If you use constants in your value, and these constants belong to a
; dynamically loaded extension (either a PHP extension or a Zend extension),
; you may only use these constants *after* the line that loads the extension.
;
;
;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
; All the values in the php.ini-dist file correspond to the builtin
; defaults (that is, if no php.ini is used, or if you delete these lines,
; the builtin defaults will be identical).

;;;;;;;;;;;;;;;;;;;;
; Language Options ;

; be supported on the target server. For portable, redistributable code,
; be sure not to use short tags.

; Output buffering allows you to send header lines (including cookies) even
; after you send body content, at the price of slowing PHP's output layer a
; bit. You can enable output buffering ring runtime by calling the output
; buffering functions. You can also enable output buffering for all files by
; setting this directive to On. If you wish to limit the size of the buffer
; to a certain size - you can use a maximum number of bytes instead of 'On', as
; a value for this directive (e.g., output_buffering=4096).
output_buffering = On

; You can redirect all of the output of your scripts to a function. For
; example, if you set output_handler to "mb_output_handler", character
; encoding will be transparently converted to the specified encoding.
; Setting any output handler automatically turns on output buffering.
; Note: People who wrote portable scripts should not depend on this ini
; directive. Instead, explicitly set the output handler using ob_start().
; Using this ini directive may cause problems unless you know what script
; is doing.
; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"
; and you cannot use both "ob_gzhandler" and "zlib.output_compression".
; Note: output_handler must be empty if this is set 'On' !!!!
; Instead you must use zlib.output_handler.
;output_handler =

; Transparent output compression using the zlib library
; Valid values for this option are 'off', 'on', or a specific buffer size
; to be used for compression (default is 4KB)
; Note: Resulting chunk size may vary e to nature of compression. PHP
; outputs chunks that are few hundreds bytes each as a result of
; compression. If you prefer a larger chunk size for better
; performance, enable output_buffering in addition.
; Note: You need to use zlib.output_handler instead of the standard
; output_handler, or otherwise the output will be corrupted.

; implications and is generally recommended for debugging purposes only.
implicit_flush = Off

; The unserialize callback function will be called (with the undefined class'

serialize_precision = 100

; Whether to enable the ability to force arguments to be passed by reference
; at function call time. This method is deprecated and is likely to be
; unsupported in future versions of PHP/Zend. The encouraged method of
; specifying which arguments should be passed by reference is in the function
; declaration. You're encouraged to try and turn this option Off and make
; sure your scripts work properly with it in order to ensure they will work

; then turn on safe_mode_gid.

; When safe_mode is on, UID/GID checks are bypassed when
; including files from this directory and its subdirectories.
; (directory must also be in include_path or full path must
; be used when including)

; When safe_mode is on, only executables located in the safe_mode_exec_dir
; will be allowed to be executed via the exec family of functions.
safe_mode_exec_dir =

; Setting certain environment variables may be a potential security breach.
; This directive contains a comma-delimited list of prefixes. In Safe Mode,
; the user may only alter environment variables whose names begin with the
; prefixes supplied here. By default, users will only be able to set
; environment variables that begin with PHP_ (e.g. PHP_FOO=BAR).
;
; Note: If this directive is empty, PHP will let the user modify ANY
; environment variable!
safe_mode_allowed_env_vars = PHP_

; This directive contains a comma-delimited list of environment variables that
; the end user won't be able to change using putenv(). These variables will be
; protected even if safe_mode_allowed_env_vars is set to allow to change them.
safe_mode_protected_env_vars = LD_LIBRARY_PATH

; open_basedir, if set, limits all file operations to the defined directory

Ⅳ 怎麼用PHP在HTML中生成PDF文件

php有很多開源的生成PDF的類庫你直接搜下就能找到
類似這樣的插件基本都輸出同樣格式就可以;
這下邊是個案列:
require_once('tcpdf.php');
//實例化
$pdf = new TCPDF('P', 'mm', 'A4', true, 'UTF-8', false);

// 設置文檔信息
$pdf->SetCreator('Helloweba');
$pdf->SetAuthor('yueguangguang');
$pdf->SetTitle('Welcome to helloweba.com!');
$pdf->SetSubject('TCPDF Tutorial');
$pdf->SetKeywords('TCPDF, PDF, PHP');

// 設置頁眉和頁腳信息
$pdf->SetHeaderData('logo.png', 30, 'Helloweba.com', '致力於WEB前端技術在中國的應用',
array(0,64,255), array(0,64,128));
$pdf->setFooterData(array(0,64,0), array(0,64,128));

// 設置頁眉和頁腳字體
$pdf->setHeaderFont(Array('stsongstdlight', '', '10'));
$pdf->setFooterFont(Array('helvetica', '', '8'));

// 設置默認等寬字體
$pdf->SetDefaultMonospacedFont('courier');

// 設置間距
$pdf->SetMargins(15, 27, 15);
$pdf->SetHeaderMargin(5);
$pdf->SetFooterMargin(10);

// 設置分頁
$pdf->SetAutoPageBreak(TRUE, 25);

// set image scale factor
$pdf->setImageScale(1.25);

// set default font subsetting mode
$pdf->setFontSubsetting(true);

//設置字體
$pdf->SetFont('stsongstdlight', '', 14);

$pdf->AddPage();

$str1 = '歡迎來到Helloweba.com';

$pdf->Write(0,$str1,'', 0, 'L', true, 0, false, false, 0);

//輸出PDF
$pdf->Output('t.pdf', 'I');

Ⅵ 在centos7安裝zlib庫,部署php環境用的,可能沒裝成功,後續安裝提示它安

1、典型的LNMP安裝問題
2、首先你得准備編譯環境
yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel openldap openldap-devel nss_ldap openldap-clients openldap-servers bison lynx
3、下載所需MySQL/nginx/php等安裝包
4、安裝nginx和mysql沒有先後順序
5、安裝php依賴包,安裝php,安裝php擴展及優化包
6、詳細的安裝步驟可以網上查LNMP安裝步驟

Ⅷ PHP擴展不載入問題,怎麼解決

方法一(已通過測試)已經內置有php_curl.dll,在ext目錄下,此DLL用於支持SSL和zlib.
1.在php.ini中找到有extension=php_curl.dll, 去掉前面的注釋.
2.設置extension_dir=c:\php\ext, 刷新PHP頁面時報錯, 說找不到模塊php_curl.dll.
拷貝php_curl.dll 到windows\system32,還是同樣的錯.
3.在網上找了一下,需要將:
libeay32.dll, ssleay32.dll, php5ts.dll, php_curl.dll
都拷貝到system32目錄下,重啟apache即可.
方法二也可試試:
1.這個php_curl.dll就依賴兩個文件(ssleay32.dll和libeay32.dll)如果這兩個文件沒有配置對那麼就會提示找不到此動態庫,這兩個文件在php的目錄下面。
2.解決辦法:在Apache的httpd.conf的文件中配置一下:
LoadFile "D:/webserver/php/ssleay32.dll"
LoadFile "D:/webserver/php/libeay32.dll"
3.然後重啟一下apache服務就ok了。

Ⅸ 在伺服器配置PHP的時候需要開通幾個擴展,請問這幾個擴展對我的網站有何用

網路不誤導你 ,我也是網路的,擴展全開都行,不妨礙你用就是了,幹嘛非要這么細致的分析每個擴展的作用呢?給你一份快餐,要麼你吃了,要麼你不吃。你會分析其他的情況嗎?
