Question

Well,I am learning the web development and currently working on PHP and mySQL,I am just totally a newbee to database concepts.To be honest Iam not sure when to create a table or when to create a database.I need some suggestions and help from you.

Okay I have these doubt kindly clear me this.I am not much aware of this but how much security does php file concepts provide us. Is there any harm in using file concepts of php?

Okay let me tell you these I want to save some data that user has entered into a text file on the server, the data might be like some message or something like his information,I wanted to save the data in a file and then save its directory path in the database. and while retrieving the data just get the file path from the database then retrieve it from the text file. Is this a good or bad idea of doing it? or should I need to save the user data in the database itself?

Similarly I also want to save the path of the images or pictures in the database and then just put the path in <img>tag.I got no one here to help me with this questions.So please help me with this,Any help is greatly appreciated.

Kindly let me know what is the way I should choose to do ?

Answer 1

For images and other file-bound resources, it makes sense to store the image on the file system and the path to it in the database. After all, file systems are great for storing files. You can store the file as a binary field in the database, so that’s certainly an option. There are pros and cons either way. Personally, I prefer to keep the files on the file system.

I’m not sure where you’re going with this:

the data might be like some message or something like his information,I wanted to save the data in a file and then save its directory path in the database

Is there a particular reason why this data needs to be in a file? Or are you just not sure how to store it in a database? If the data is structured and consistently organized then I can’t imagine a reason not to keep it in a relational database. (And even if it isn’t as structured, I’d probably still look into a database over the file system for this sort of thing.)

Images and other non-relational resources are generally file-bound, so keep them in files. But if you’re just storing text in a text file for no other reason than that’s what you’ve always done, I’d recommend using a database.
