Mistakes are possible in any type of programming, but PHP frameworks help to limit these mistakes greatly by providing good quality code that is tried and true from the start of the development process. Repetitive coding seems to promote mistakes now and then, and frameworks all but eliminate that problem.
That being said, there are still things to be careful of when utilizing any PHP framework. For instance, unless you are an expert in PHP programming, you should always opt for using a popular framework with plenty of support and an active user base (see below for examples of popular PHP frameworks). There are many frameworks out there that have little or no support, and/or they were created by individuals with limited knowledge of PHP. These types of frameworks can cause your applications to not function properly, and worse case scenario, could cause catastrophic security issues with your website.
Another somewhat common mistake is not ensuring your database and web server is compatible with the particular framework. For example, Seagull PHP Framework recommends the following configuration:
PHP: PHP 4.3.0 is the minimum, later versions work fine, as do versions PHP 5.1.1 and above. Avoid anything in the 5.0.x series
MySQL: MySQL 4.0.x, 4.1.x and 5.0.x are all supported. You can also use 3.23.x.
Apache: Seagull works fine with 1.3.x and 2.x series of Apache
If you don’t meet these requirements, you won’t be observing the best performance possible from your chosen framework. Even if you are an expert in PHP, you should always go over the documentation of the framework to confirm compatibility before trying it out.
Similar to the previously mentioned common mistake, not following the recommended installation process of your PHP framework can also give you some headaches. Take Seagull as an example again – the Seagull wiki has a detailed rundown of the framework’s installation process that has several key steps that are sometimes easily overlooked by careless or unsuspecting developers. The key is to take your time setting up the framework and follow the installation instructions to the “T” – The time you’ll save actually developing applications later will more than make up for the few extra minutes spent installing the framework correctly the first time.
