phpzlib擴展
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).

; 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

; 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"

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？
