Warning: Backing up all known pear.conf and .pearrc files
Warning: If you have a pre-existing pear install outside
         of homebrew-php, or you are using a non-standard
         pear.conf location, installation may fail.

==> Caveats
For 10.5 and Apache:
    Apache needs to run in 32-bit mode. You can either force Apache to start
    in 32-bit mode or you can thin the Apache executable.

To enable PHP in Apache add the following to httpd.conf and restart Apache:
    LoadModule php5_module    /usr/local/Cellar/php53/5.3.17/libexec/apache2/libphp5.so

The php.ini file can be found in:
    /usr/local/etc/php/5.3/php.ini

✩✩✩✩ PEAR ✩✩✩✩

If pear complains about permissions, 'Fix' the default PEAR permissions and config:
    chmod -R ug+w /usr/local/Cellar/php53/5.3.17/lib/php
    pear config-set php_ini /usr/local/etc/php/5.3/php.ini

✩✩✩✩ Extensions ✩✩✩✩

If you are having issues with custom extension compiling, ensure that this php is
in your PATH:
    PATH="$(brew --prefix josegonzalez/php/php53)/bin:$PATH"

PHP53 Extensions will always be compiled against this PHP. Please install them
using --without-homebrew-php to enable compiling against system PHP.

✩✩✩✩ FPM ✩✩✩✩

If you have installed the formula with --with-fpm, to launch php-fpm on startup:
    * If this is your first install:
        mkdir -p ~/Library/LaunchAgents
        cp /usr/local/Cellar/php53/5.3.17/homebrew-php.josegonzalez.php53.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php53.plist

    * If this is an upgrade and you already have the homebrew-php.josegonzalez.php53.plist loaded:
        launchctl unload -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php53.plist
        cp /usr/local/Cellar/php53/5.3.17/homebrew-php.josegonzalez.php53.plist ~/Library/LaunchAgents/
        launchctl load -w ~/Library/LaunchAgents/homebrew-php.josegonzalez.php53.plist

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.
Warning: Could not link php53. Unlinking...

==> Caveats
To finish installing xdebug for PHP 5.3:
  * /usr/local/etc/php/5.3/conf.d/ext-xdebug.ini was created,
    do not forget to remove it upon extension removal.
  * Restart your webserver.
  * Write a PHP page that calls "phpinfo();"
  * Load it in a browser and look for the info on the xdebug module.
  * If you see it, you have been successful!
