pathname to the Apache apxs tool apxs
4.--with-mysql=DIR

Include MySQL support. DIR is the MySQL base directory, if no DIR is passed or the value is
mysqlnd the MySQL native driver will be used
5.--with-mysqli=FILE
加入mysqli支持,没有设置默认是mysqlnd
Include MySQLi support. FILE is the path to mysql_config. If no value or mysqlnd is passed
as FILE, the MySQL native driver will be used
6.--with-pdo-mysql=DIR
加入pdo支持,默认为自带驱动mysqlnd
PDO: MySQL support. DIR is the MySQL base directory If no value or mysqlnd is passed as DIR, the
MySQL native driver will be used
7.--with-mysql-sock=SOCKPATH
指定mysql套接字文件位置,如果没指定则搜索默认位置
MySQL/MySQLi/PDO_MYSQL: Location of the MySQL unix socket pointer.
If unspecified, the default locations are searched
8.--enable-sockets
开启sockets支持
Enable sockets support
9.--with-libxml-dir=DIR
libxml2 安装位置
SimpleXML: libxml2 install prefix
10.--enable-mbstring
使php支持对多字节字符串的处理
Enable multibyte string support
11.--with-gd=DIR
Include GD support. DIR is the GD library base install directory BUNDLED
12.--with-curl=DIR

14.--enable-zip Include Zip read/write support
15.--enable-calendar
支持日历转换
Enable support for calendar conversion
16.--with-zlib=DIR

Include ZLIB support (requires zlib >= 1.0.9)
17.--enable-bcmath
打开图片大小调整,用到zabbix监控的时候用到了这个模块
Enable bc style precision math functions
18. --enable-soap Enable SOAP support
19.--with-iconv-dir=DIR XMLRPC-EPI: iconv dir for XMLRPC-EPI

GD: Set the path to FreeType 2 install prefix
21.--with-jpeg-dir=DIR
打开对jpeg图片的支持
GD: Set the path to libjpeg install prefix
22.--with-png-dir=DIR
打开对png图片的支持
GD: Set the path to libpng install prefix
23.--without-sqlite3=DIR
自PHP5.3起默认启用SQLite3 扩展,可以在编译时使用--without-sqlite3禁用SQLite3 扩展
Do not include SQLite3 support. DIR is the prefix to SQLite3 installation directory.
24.--enable-exif
开启图片的元数据支持
Enable EXIF (metadata from images) support
25.--enable-ftp Enable FTP support
26.--with-pcre-dir
FILTER: pcre install prefix
27.--disable-fileinfo

31.--enable-fpm Enable building of the fpm SAPI executable
--with-fpm-user=USER Set the user for php-fpm to run as. (default: nobody)
--with-fpm-group=GRP Set the group for php-fpm to run as. For a system user, this
should usually be set to match the fpm username (default: nobody)
32.--enable-posix
开启posix扩展支持
33.--enable-pcntl
开启pcntl扩展
34.--with-pear=DIR Install PEAR in DIR [PREFIX/lib/php]
--without-pear Do not install PEAR

需要单独安装的扩展
gd库, mbstring, mhash和mcrypt
1.指定了--with-apxs2=/usr/local/apache/bin/apxs以后，就不要再激活--enable-fpm和--enable-fastCGI，apxs是以php module的模式加载PHP的.
2.Mysql在编译了Mysql开发library以后，可以不用指定mysql的路径.
3.PHP编译存在基础的依赖的关系，编译PHP首先需要安装XML扩展，因为php5核心默认打开了XML的支持，其他的基础库，相应需要
4.GD -> zlib, Png, Jpg, 如果需要支持其他，仍需要根据实际情况编译扩展库，ttf库需要freetype库的支持。
5.--enable-magic-quotes，是一个极其不推荐的参数，当然，如果你需要PHP为你做这些底下的工作，实际上他也没有很彻底的解决问题。
6.-with-openssl 需要openssl库

mysqli是MySQL团队提供的MySQL驱动，具有很多实用的功能和典型特征。不过他不是MySQL于PHP平台最好的选择，PDO被证实，是一个简易、高并发性，而且易于创建和回收的标准接口。不过PDO也经历了5.3以前的内存溢出的问题，在5.3以后，在读取Oracle的LOB资源时，若不对内存进行限制，仍会内存溢出。
如果是生产环境,好像pear、shmop、ftp等，都不推荐使用,语言，都有很好很快速的选择，无需局限于使用PHP去实现。不熟悉的类库和不常用的库，也不推荐使用。
magic-quote、session.auto_start、PHP服务器信息、PHP报错信息等在编译完成后，应该第一时间关闭，避免暴露服务器信息。
PHP对应的Web Server模式，Module、fastcgi、fpm只需要一种即可，服务器不是你的试验田。fastcgi可以选择Nginx和lighttpd，其实Nginx也是使用lighttpd的spwan-fcgi进行fcgi进程管理的。fpm是使用PHP自身去管理多进程，有点类似一个后端代理。无论什么模式，在发布产品服务器，都应该做进程和线程调优，做足够多的性能及压力方面的测试，找出最好的进程数组合。
选好一种PHP OPCode cache的扩展，这个也是很重要的，linux 2.6核心下，fcgi下,xcache有较好的实践经验，其他的在并发数增加以后，性能衰减严重。
如果真的想体验宁可编译多几个PHP版本，也不要针对一个版本的PHP集合各种扩展，适应各种环境，这会让把你自己逼进窘境的。

DIR is the MySQL base directory                          If no value or mysqlnd is passed as DIR, the                          MySQL native driver will be used  --with-zlib-dir=DIR     PDO_MySQL: Set the path to libz install prefix  --with-pdo-oci=DIR      PDO: Oracle OCI support. DIR defaults to \$ORACLE_HOME.                          Use --with-pdo-oci=instantclient,prefix,version                          for an Oracle Instant Client SDK.                          For example on Linux with 11.2 RPMs use:                            --with-pdo-oci=instantclient,/usr,11.2                          With 10.2 RPMs use:                            --with-pdo-oci=instantclient,/usr,10.2.0.4  --with-pdo-odbc=flavour,dir                          PDO: Support for 'flavour' ODBC driver.              include and lib dirs are looked for under 'dir'.              'flavour' can be one of:  ibm-db2, iODBC, unixODBC, generic              If ',dir' part is omitted, default for the flavour              you have selected will be used. e.g.:                --with-pdo-odbc=unixODBC              will check for unixODBC under /usr/local. You may attempt              to use an otherwise unsupported driver using the \"generic\"              flavour.  The syntax for generic ODBC support is:                --with-pdo-odbc=generic,dir,libname,ldflags,cflags              When built as 'shared' the extension filename is always pdo_odbc.so  --with-pdo-pgsql=DIR    PDO: PostgreSQL support.
