    <p>Apples and oranges.</p> <p>You can go to a drag race with a Hummer and complete the race but you will surely be in last compared to a Bugatti. Take a Bugatti off-road and it will definitely fall behind the Hummer.</p> <p>PHP is a server side scripting language. Data storage and retrieval is not the primary consideration in PHP.</p> <p>mySQL is a relational database management system. It's design is 100% purposed for data storage, retrieval, and security. </p> <p>What's your plan for data storage and retrieval in PHP? It seems like will have to do a lot of unnecessary work re-inventing the wheel to achieve this. Why would you? </p> <p>Without understanding what security concerns you are specifically worried about in mySQL there isn't much more to add.</p> <p>Edit: <a href="http://www.dummies.com/how-to/content/storing-data-with-php-flat-file-or-database.html" rel="nofollow">An article calling out the general differences.</a></p>

    1. COit was a simple question with probably a simple (and maybe big) answer that i don't know. what are the security implications of storing, let's say, non-malicious string/array data in a .php file? how someone could see it or modify it. also your analogy is pretty funny because chances are the bugatti wouldn't finish the off road course xD

    2. CO@wxiiir haha good point :) So to answer your question regarding access of data in flat php files.. it would be coupled with access to your file system. Consider the recent exploit of TimThumb (a popular thumbnail creating script in PHP) http://wpcandy.com/reports/timthumb-security-vulnerability-discovered. Exploiters figured out how to allow themselves to upload and execute arbitrary PHP code in the TimThumb cache directory. Now imagine if this PHP code simply dumped the contents of all files in the web directory... they now have all your data.

    3. COthis is good information. let's say that if i had this website that was hacked they could easily see the information that would be stored on plain php files (if i stored it this way). now the question is, why wouldn't they be able to see the information of my databases (if instead of using plain php files i would use a mysql database)? i guess that it wouldn't be of any difficulty for hackers to access the databases when able to execute any php code inside the website, maybe it would take them 10 more minutes at best than accessing the information on plain php files, am i wrong?

Querying!

 
Guidance
A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
