这里有新鲜出炉的PHP面向对象编程,程序狗速度看过来!

PHP开源脚本语言

PHP(外文名: Hypertext Preprocessor,中文名:“超文本预处理器”)是一种通用开源脚本语言。语法吸收了C语言、Java和Perl的特点,入门门槛较低,易于学习,使用广泛,主要适用于Web开发领域。PHP的文件后缀名为php。


本文讲解是在mac系统下安装php开发环境,MAC本来就自带了 php,但是很多扩展没有安装,所以选择了重新安装php并升级到最新版,下面说说安装步骤,感兴趣的同学参考下.

brew简介:

Brew 是 Mac 下面的包管理工具,通过 Github 托管适合 Mac 的编译配置以及 Patch,可以方便的安装开发工具。 Mac 自带ruby 所以安装起来很方便,同时它也会自动把git也给你装上。官方胜博发888手机平台: http://brew.sh
 
安装方法:

ruby -e "$(curl -fsSL https://raw.github.com/Homebrew/homebrew/go/install)"

使用以下方法可以查看brew是否安装成功,以及目前的版本:

liondeMacBook-Pro:~ lion$ brew -v
Homebrew 0.9.5

添加brew的PHP扩展库:

liondeMacBook-Pro:~ lion$ brew update
liondeMacBook-Pro:~ lion$ brew tap homebrew/dupes
liondeMacBook-Pro:~ lion$ brew tap homebrew/php
liondeMacBook-Pro:~ lion$ brew tap josegonzalez/homebrew-php

 
可以使用brew options php55命令查看安装时可以有哪些选项,因为我之前安装过curl、libxslt、openssl所以,在选项中会提示是否使用brew安装的相关扩展:

liondeMacBook-Pro:Library lion$ brew options php55
--disable-opcache
  Build without Opcache extension
--disable-zend-multibyte
  Disable auto-detection of Unicode encoded scripts (PHP 5.2 and 5.3 only)
--homebrew-apxs
  Build against apxs in Homebrew prefix
--with-apache
  Enable building of shared Apache 2.0 Handler module, overriding any options which disable apache
--with-cgi
  Enable building of the CGI executable (implies --without-apache)
--with-debug
  Compile with debugging symbols
--with-fpm
  Enable building of the fpm SAPI executable (implies --without-apache)
--with-gmp
  Build with gmp support
--with-homebrew-curl

--HEAD
  install HEAD version

开始安装PHP5.5.15,安装后的php-fpm.ini以及php.ini都在目录:/usr/local/etc/php/5.5/下面

liondeMacBook-Pro:Library lion$ brew install php55 --with-mssql --with-homebrew-openssl --with-homebrew-libxslt --with-homebrew-curl --with-fpm --with-debug --with-gmp --with-imap --with-tidy --with-libmysql

==> Caveats
This formula is keg-only, which means it was not symlinked into /usr/local.
Mac OS X already provides this software and installing another version in
parallel can cause all kinds of trouble.
Generally there are no consequences of this for you. If you build your
own software and it requires this formula, you'll need to add to your
build variables:
  LDFLAGS: -L/usr/local/opt/curl/lib
  CPPFLAGS: -I/usr/local/opt/curl/include

==> Caveats
The php.ini file can be found in:
  /usr/local/etc/php/5.5/php.ini
✩✩✩✩ PEAR ✩✩✩✩
If PEAR complains about permissions, 'fix' the default PEAR permissions and config:
  chmod -R ug+w /usr/local/Cellar/php55/5.5.15/lib/php
  pear config-set php_ini /usr/local/etc/php/5.5/php.ini
✩✩✩✩ Extensions ✩✩✩✩
If you are having issues with custom extension compiling, ensure that
you are using the brew version, by placing /usr/local/bin before /usr/sbin in your PATH:
   PATH="/usr/local/bin:$PATH"
PHP55 Extensions will always be compiled against this PHP. Please install them
using --without-homebrew-php to enable compiling against system PHP.
✩✩✩✩ PHP CLI ✩✩✩✩
If you wish to swap the PHP you use on the command line, you should add the following to ~/.bashrc,
~/.zshrc, ~/.profile or your shell's equivalent configuration file:
   export PATH="$(brew --prefix homebrew/php/php55)/bin:$PATH"
✩✩✩✩ FPM ✩✩✩✩
To launch php-fpm on startup:
  * If this is your first install:
    mkdir -p ~/Library/LaunchAgents
    cp /usr/local/Cellar/php55/5.5.15/homebrew.mxcl.php55.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php55.plist
  * If this is an upgrade and you already have the homebrew.mxcl.php55.plist loaded:
    launchctl unload -w ~/Library/LaunchAgents/homebrew.mxcl.php55.plist
    cp /usr/local/Cellar/php55/5.5.15/homebrew.mxcl.php55.plist ~/Library/LaunchAgents/
    launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php55.plist
The control script is located at /usr/local/Cellar/php55/5.5.15/sbin/php55-fpm
Mountain Lion comes with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /usr/local/sbin is before /usr/sbin in your PATH:
 PATH="/usr/local/sbin:$PATH"
You may also need to edit the plist to use the correct "UserName".
Please note that the plist was called 'homebrew-php.josegonzalez.php55.plist' in old versions
of this formula.
To have launchd start php55 at login:
  ln -sfv /usr/local/opt/php55/*.plist ~/Library/LaunchAgents
Then to load php55 now:
  launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php55.plist
==> Summary
 /usr/local/Cellar/php55/5.5.15: 477 files, 43M, built in 3.9 minutes

过程中如果出现configure: error: Cannot find OpenSSL's <evp.h>这样的错误,请执行以下命令,将xcode进行更新:

xcode-select --install

在PHP5安装完成的提示中写到,如何进行PHP5和mac自带的php以及php-fpm替换,执行以下命令后,我们可以看到当前的php版本已经是最新的了:

liondeMacBook-Pro:~ lion$ echo 'export PATH=/usr/local/bin:$PATH' >> ~/.bash_profile
liondeMacBook-Pro:~ lion$ echo 'export PATH=/usr/sbin:$PATH' >> ~/.bash_profile
liondeMacBook-Pro:~ lion$ echo 'export PATH=/usr/local/sbin:$PATH' >> ~/.bash_profile
liondeMacBook-Pro:~ lion$ source ~/.bash_profile 
liondeMacBook-Pro:~ lion$ php -v
PHP 5.5.15 (cli) (built: Aug 14 2014 15:37:16) (DEBUG)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.5.0, Copyright (c) 1998-2014 Zend Technologies
liondeMacBook-Pro:~ lion$

 
使用brew search php55-命令,可以查看还有哪些扩展可以安装,然后执行brew install php55-XXX就可以了。

liondeMacBook-Pro:~ lion$ brew search php55-
php55-amqp    php55-igbinary    php55-msgpack    php55-runkit     php55-varnish
php55-apcu    php55-imagick    php55-mysqlnd_ms   php55-scrypt     php55-vld

php55-binpack    php55-intl    php55-opcache    php55-solr      php55-xcache
php55-blitz   php55-ioncubeloader   php55-parsekit    php55-sphinx     php55-xdebug
php55-boxwood    php55-jsmin     php55-pcntl     php55-spl-types   php55-xhgui

php55-dbase   php55-libvirt    php55-phalcon    php55-sundown    php55-yac
php55-dbus    php55-lz4    php55-proctitle   php55-svm      php55-yaf
php55-dmtx    php55-lzf    php55-propro     php55-swoole     php55-yaml
php55-ev     php55-mailparse   php55-protobuf    php55-thrift     php55-yar
php55-gearman    php55-mcrypt     php55-pspell     php55-tidy      php55-yaz
php55-geoip   php55-memcache    php55-pthreads    php55-timezonedb   php55-yp
php55-gmagick    php55-memcached   php55-raphf     php55-tokyotyrant    php55-yrmcds
php55-graphdat    php55-midgard2    php55-redis     php55-twig      php55-zmq
php55-htscanner   php55-mongo     php55-redland    php55-uploadprogress   php55-zookeeper
php55-http    php55-mosquitto   php55-riak      php55-uuid

我安装的是以下php5.5几个扩展:

liondeMacBook-Pro:~ lion$ brew install php55-imagick php55-igbinary php55-ev php55-gmagick php55-geoip php55-memcache php55-memcached php55-thrift php55-xdebug php55-sphinx composer

接下来我们测试php-fpm的配置是否正确,以及是否正确启动:

#测试php-fpm配置是否正确
liondeMacBook-Pro:bin lion$ php-fpm -t
[14-Aug-2014 16:14:30] NOTICE: configuration file /usr/local/etc/php/5.5/php-fpm.conf test is successful
liondeMacBook-Pro:bin lion$ php-fpm -c /usr/local/etc/php/5.5/php.ini -y /usr/local/etc/php/5.5/php-fpm.conf -t
[14-Aug-2014 16:14:48] NOTICE: configuration file /usr/local/etc/php/5.5/php-fpm.conf test is successful
#启动php-fpm
liondeMacBook-Pro:bin lion$ launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.php55.plist
#查看9000端口是否在运行
liondeMacBook-Pro:bin lion$ lsof -i:9000
COMMAND  PID USER  FD  TYPE       DEVICE SIZE/OFF NODE NAME
php-fpm 51241 lion  8u IPv4 0xce9d0f6417637937   0t0 TCP localhost:cslistener (LISTEN)
php-fpm 51243 lion  0u IPv4 0xce9d0f6417637937   0t0 TCP localhost:cslistener (LISTEN)
php-fpm 51244 lion  0u IPv4 0xce9d0f6417637937   0t0 TCP localhost:cslistener (LISTEN)
php-fpm 51245 lion  0u IPv4 0xce9d0f6417637937   0t0 TCP localhost:cslistener (LISTEN)
#关闭掉php-fpm进程,再查看9000端口,没有监听了
liondeMacBook-Pro:bin lion$ ps aux|grep php-fpm|grep -v 'grep'|awk '{print $2}'|xargs kill -9
liondeMacBook-Pro:bin lion$ lsof -i:9000
liondeMacBook-Pro:bin lion$

设置PHP-FPM开机运行(其实在安装完成的提示中,也有说明):

ln -sfv /usr/local/opt/php55/*.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php55.plist
