Mac に PHP5.4 を Homebrew でインストールしたのでメモ。

デフォルトでは、PHPのFormulaは無いので、homebrew-phpを使ってインストールします。

==> make install
==> /usr/local/Cellar/php54/5.4.16/bin/pear config-set php_ini /usr/local/etc/php/5.4/php.ini
==> Caveats
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/php54/5.4.16/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/php54/5.4.16/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/php54/5.4.16/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/php54/5.4.16/sbin/php54-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 '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
