mac下面安装php5.4

苹果下面安装php5.4还算是比较方便的，主要是默认为php5.3，想用trait的时候，没5.4跑不了

苹果下面安装php5.4还算是比较方便的，主要是默认为php5.3，想用trait的时候，没5.4跑不了啊。。

于是直接使用brew install php54，结果报错，查了下资料，原来，需要：

• brew tap josegonzalez/homebrew-php
• brew tap homebrew/dupes
• brew install php54 --with-mysql --with-intl --with-fpm --without-apache

因为有装nginx。所以就without-apache了。。。

安装好后，brew 会告诉你：

    The php.ini file can be found in:  
        /usr/local/etc/php/5.4/php.ini  
    ???? PEAR ????  
    If PEAR complains about permissions, 'fix' the default PEAR permissions and config:  
        chmod -R ug+w /usr/local/Cellar/php54/5.4.13/lib/php  
        pear config-set php_ini /usr/local/etc/php/5.4/php.ini  
    ???? Extensions ????  
    If you are having issues with custom extension compiling, ensure that this php is  
    in your PATH:  
        PATH="$(brew --prefix josegonzalez/php/php54)/bin:$PATH"  
    PHP54 Extensions will always be compiled against this PHP. Please install them  
    using --without-homebrew-php to enable compiling against system PHP.  
    ????? INTL Support ?????  
    icu4c is broken as of mxcl/homebrew#03ed757c, so you will need to install intl as  
    a separate extension:  
        brew install php54-intl  
    ???? FPM ????  
    To launch php-fpm on startup:  
        * If this is your first install:  
            mkdir -p ~/Library/LaunchAgents  
            cp /usr/local/Cellar/php54/5.4.13/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/  
            launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist  
        * If this is an upgrade and you already have the homebrew-php.josegonzalez.php54.plist loaded:  
            launchctl unload -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist  
            cp /usr/local/Cellar/php54/5.4.13/homebrew-php.josegonzalez.php54.plist ~/Library/LaunchAgents/  
            launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php54.plist  
    The control script is located at /usr/local/Cellar/php54/5.4.13/sbin/php54-fpm  
    Mountain Lion comes with php-fpm pre-installed, to ensure you are using the brew version you need to make sure /sbin is before /usr/sbin in your PATH:  
      PATH="/sbin:$PATH"  
    You may also need to edit the plist to use the correct "UserName".  
    Please note that the plist was called 'org.php-fpm.plist' in old versions  
    of this formula.  
    To have launchd start php54 at login:  
        ln -sfv /usr/local/opt/php54/*.plist ~/Library/LaunchAgents  
    Then to load php54 now:  
        launchctl load ~/Library/LaunchAgents/homebrew.mxcl.php54.plist  
    Warning: /usr/local/sbin is not in your PATH  
    You can amend this by altering your ~/.bashrc file  

记下这些路径和使用方法，以后会用得到
