  • Wildan Maulana | wildan [at] tobethink.com #3 The Definitive Guide to symfony Running Symfony Doc. v. 0.1 - 14/04/09
  • Requirement
    • Symfony requires at least PHP 5.2. Make sure you have it installed by opening a command line and typing this command:
    > php -v PHP 5.2.6-2ubuntu4 with Suhosin-Patch 0.9.6.2 (cli) (built: Oct 14 2008 20:06:32) Copyright (c) 1997-2008 The PHP Group Zend Engine v2.2.0, Copyright (c) 1998-2008 Zend Technologies
  • Symfony Installation Method
    • Use sandbox if you just wanna see what is symfony capable of
    • Use PEAR installation method, it is recommended for most people
    • Use Subversion (SVN) installation, it is meant to be used by advanced PHP developers, who want to take advantage of the latest patches, add features of their own, and/or contribute to the symfony project. Btw, I prefer using SVN installation method
  • Installing the Sandbox
    • The sandbox is a simple archive of files. It contains an empty symfony project including all the required libraries (symfony, lime, Prototype with Scriptaculous, Doctrine and Propel with Phing), a default application, and basic configuration. It will work out of the box, without specific server configuration or any additional packages.
    • Download from : http://www.symfony-project.org/get/sf_sandbox_1_2.tgz
      • Unpack it to the root web directory (I assume you to use sf_sandbox/ directory)
      • Test the installation : > php symfony -V You will see sandbox version number : symfony version 1.2.0 (/path/to/the/symfony/lib/dir/used/by/the/sandbox)
    • Try to browse the sandbox by requesting this URL : http://localhost/sf_sandbox/web/frontend_dev.php/
  • Installing symfony Libraries
    • Using symfony PEAR package
    • Using Subversion (SVN)
  • Installing the symfony PEAR Package
    • Add the symfony channel to PEAR > pear channel-discover pear.symfony-project.com
    • To see the libraries available in this channel, type the following: > pear remote-list -c symfony
    • Now you are ready to install the latest stable version of symfony. Issue this command: > pear install symfony/symfony
    • downloading symfony-1.2.0.tgz ...
    • Starting to download symfony-1.2.0.tgz (1,283,270 bytes)
    • .................................................................
    • .................................................................
    • .............done: 1,283,270 bytes
    • install ok: channel://pear.symfony-project.com/symfony-1.2.0
    • Check that the installation succeeded > symfony -V
    • symfony version 1.2.0 (/path/to/the/pear/symfony/lib/dir)
  • Installing the symfony PEAR Package
    • The symfony libraries are now installed in directories as follows:
      • $php_dir/symfony/ contains the main libraries.
      • $data_dir/symfony / contains the web assets used by symfony default modules.
      • $doc_dir/symfony/ contains the documentation.
      • $test_dir/symfony/ contains symfony core unit and functional tests.
    • The _dir variables are part of your PEAR configuration. To see their values, type the following:
      • > pear config-show
  • Checking Out symfony from the SVN Repository
    • # > mkdir /path/to/symfony
    • # > cd /path/to/symfony
    • # > svn checkout http://svn.symfony-project.com/tags/RELEASE_1_2_0/
    • > php /path/to/symfony/data/bin/symfony -V
    • symfony version 1.2.0 (/path/to/the/svn/symfony/lib/dir)
    <?php require_once '/path/to/symfony/lib/autoload/sfCoreAutoload.class.php'; sfCoreAutoload::register(); class ProjectConfiguration extends sfProjectConfiguration { // ... }
  • Setting Up an Application
    • Creating the Project
    • Creating the Application
  • Creating Project For a PEAR installation, issue these commands: > mkdir ~/myproject > cd ~/myproject > symfony generate:project myproject For an SVN installation, create a project with these commands: > mkdir ~/myproject > cd ~/myproject > php /path/to/symfony/data/bin/symfony generate:project myproject apps/ cache/ config/ data/ doc/ lib/ log/ plugins/ test/ web/ Symfony will create a directory structure that looks like this:
  • Creating the Application
    • The project is not ready for viewing before you create at least one application in it.
    • To initialize application use the symfony generate:app command >php symfony generate:app frontend
    • This will create a frontend/ directory in the apps/ folder of the project root, with a default application configuration and a set of directories ready to host the file of your website:
    apps/ frontend/ config/ i18n/ lib/ modules/ templates/ web/ index.php frontend_dev.php index.php -> front controller in production environment frontend_dev.php -> front controller in development environment
  • Configuring the Web Server
    • There are several cases :
      • Setting Up a Virtual Host
      • Setting Up an Alias
      • Configuring a Shared-Host Server
  • Setting Up a Virtual Host <VirtualHost *:80> ServerName myapp.example.com DocumentRoot &quot;/home/steve/myproject/web&quot; DirectoryIndex index.php Alias /sf /$sf_symfony_data_dir/web/sf <Directory &quot;/$sf_symfony_data_dir/web/sf&quot;> AllowOverride All Allow from All </Directory> <Directory &quot;/home/steve/myproject/web&quot;> AllowOverride All Allow from All </Directory> </VirtualHost> Don't fortget to setup your DNS entry for your application address first
  • Setting Up an Alias
  • Configuring a Shared-Host Server
    • This is a little trickier, since host usually has spesific directory layout that you can't change
  • .htaccess Options +FollowSymLinks +ExecCGI <IfModule mod_rewrite.c> RewriteEngine On # uncomment the following line, if you are having trouble # getting no_script_name to work #RewriteBase / # we skip all files with .something #RewriteCond %{REQUEST_URI} ..+$ #RewriteCond %{REQUEST_URI} !.html$ #RewriteRule .* - [L] # we check if the .html version is here (caching) RewriteRule ^$ index.html [QSA] RewriteRule ^([^.]+)$ $1.html [QSA] RewriteCond %{REQUEST_FILENAME} !-f # no, so we redirect to our front web controller RewriteRule ^(.*)$ index.php [QSA,L] </IfModule>
  • Browse Your New App http://www.example.com/frontend_dev.php/
  • Troubleshooting
    • Parse error, unexpected ',', expecting '(' in .../symfony.php on line 19.
    • Allowed memory size of 8388608 bytes exhausted
    • Strict Standards: Implicit cloning object of class 'sfTimer'because of 'zend.ze1_compatibility_mode'
    • sfCacheException [message] Unable to write cache file&quot;/usr/myproject/cache/frontend/prod/config/config_config_handlers.yml.php&quot;
    • The include path of your system must include the path to the php command, and the include path of your php.ini must contain a path to PEAR (if you use PEAR).
    • Sometimes, there is more than one php.ini on a server's file system (for instance, if you use the WAMP package). Call phpinfo() to know the exact location of the php.ini file used by your application.
  • Symfony Resources
    • The symfony installation forum (http://www.symfony-project.org/forum/)
    • The archives of the users mailing-list (http://groups.google.fr/group/symfony-users)
    • The symfony wiki (http://trac.symfony-project.org/
  • Source Versioning
    • > svnadmin create $SVNREP_DIR/myproject
    • > svn mkdir -m &quot;layout creation&quot; file:///$SVNREP_DIR/myproject/trunk file:///$SVNREP_DIR/myproject/tags file:///$SVNREP_DIR/myproject/branches
    • > cd ~/myproject
    • rm -rf cache/*
    • rm -rf log/*
    • svn import -m &quot;initial import&quot; . file:///$SVNREP_DIR/myproject/trunk
    • > svn ls file:///$SVNREP_DIR/myproject/trunk/
    • > cd ~
    • > mv myproject myproject.origin
    • > svn co file:///$SVNREP_DIR/myproject/trunk myproject
    • > ls myproject
    • > cd ~/myproject
    • > chmod 777 cache
    • > chmod 777 log
    • > svn propedit svn:ignore log
    • > svn propedit svn:ignore cache
    • > export SVN_EDITOR=<name of editor>
    • > svn propedit svn:ignore log
    • > svn propedit svn:ignore cache
    • Write * , save and quit.
    • You're finished
  • Summary
    • For symfony 1 st time user, your best option is using the sandbox version
    • For real development, consider to use the SVN version
    • Once your project is initiated, it is a good habit to start a version-control process.
