PHP Code Snippets: You Need to Know What Browser is Running
By admin ( 2008-09-20 7454 views. )
While developing a CSS heavy site using Joomla there are times where you just have to know - is this IE or not. Luckily (really not luck, the PHP folks always have a toolset available that you might need) the PHP standard library has a function to determine the browser capability. At this point $browser is either "IE" or something else. That is really all you care to know typically. Then can do all the neato CSS different things you want to do. By the way, the $browsercap has a boatload of other stuff that you may care about.

PHP Code Snippets: How to Rebuild the Symfony Data Model Layer
By admin ( 2006-12-26 7216 views. )
I find that when developing I would normally use some other tool, such as phpmyadmin, to modify the structure of an existing database that I am using in a Symfony project. These are the steps to update the Symfony data model code generated from an acompanying MySql database. I find I have to run these steps often while developing the application. Assuming you are shelled into the root of your application directory. Also assumes that propel.ini points to your database. 1) We generate the schema using step 1. This will generate the schema.yml file in your app/config directory. 2) While YML is nice, we really need XML so, we use this step 2command. Again, this is quite verbose and not really human readable. 3) Finally, generate the code we use in base and peer classes using step 3. The actual database access layer code is generated in the app/lib/model directory with names like Tablename.php and TablenamePeer.php. You normally use these objects for all database access. This also generates all the BaseTablename.php and BaseTablenamePeer.php files in your app/lib/model/om directory. These are used as base classes in the previous code set. This the first of a series of shorts on developing in Symfony
