mac环境中使用brew安装php5.5.15

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，希望对大家有所帮助

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。官方网站：
 
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 Include Curl support via Homebrew --with-homebrew-libxslt Include LibXSLT support via Homebrew --with-homebrew-openssl Include OpenSSL support via Homebrew --with-imap Include IMAP extension --with-intl Include internationalization support --with-libmysql Include (old-style) libmysql support instead of mysqlnd --with-mssql Include MSSQL-DB support --with-pdo-oci Include Oracle databases (requries ORACLE_HOME be set) --with-pgsql Include PostgreSQL support --with-phpdbg Enable building of the phpdbg SAPI executable (PHP 5.4 and above) --with-thread-safety Build with thread safety --with-tidy Include Tidy support --without-bz2 Build without bz2 support --without-mysql Remove MySQL/MariaDB support --without-pcntl Build without Process Control support --without-pear Build without PEAR --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

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 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：
