So far, there hasn’t been much PHP code in this tutorial. That’s one of the strengths of symfony: it doesn’t force you to write code that symfony can generate itself based on simple data. However, you will need to write a few lines of PHP for the tags in the model. First, let’s explore the model’s structure.
We’ll use a great feature of the symfony framework called the administration generator to create a site administration panel. The administration generator uses the relational schema as a guideline to create a data manipulation interface.

Although it can be run as an interpreted script like other scripting languages, it is designed first and foremost around dynamically generating HTML pages. Combined with a robust set of libraries and one of the best, most comprehensive programming manuals on the web, you can do some totally sweet stuff with it. Read the rest of this entry »
