PHP - Please Help Me Out On My Php Ecommerce Website

I actually bought an E-Commerce app an the issue with it is the app process is very slow while opening and while jumping from one page to another its an admin panel web based app so i want to know IF there is a way to solve the issue by coding a line or two

(Language used in the app and admin panel is "PHP')

I've been working on JSON and have found a way to send variables from the PHP to the JavaScript using AJAX and no JQuery.  For an ecommerce site does it make more sense to send the variables : description, title, cost, etc. to the JavaScript page,  or would it make more sense to echo the html on the PHP page?  The idea, right now, is a product page for editing and deleting product. 

Thanks,

Josh

Hey, I am looking for an ecommerce system or just the way how to achieve the following. I am wanting to store some MP3 sound files in a folder called for example 'sounds' on my web server. I then want to be able to stream the files onto my web pages but then I also want people to be able to purchase them. This is where I get confused, how can I achieve this without letting people just be able to download the 'sounds' directory off my web server. I am wanting to do this using PHP obviously. Thanks in advance for help

I'm trying to make a League of Legends (a video game) community website, both as a personal project and for practice.
Now the game has a lot of champions, each of whom have 5 unique abilities. Now, I thought about manually inputting all the details about each champion into a MySQL database, but that would long and tedious, and I don't really have the time for it now. Also, the game patches very oftern (like, once every 2 weeks) which changes many of the stats, etc. of the champion, and it is not possible for me to keep manually updating these every time there is a patch.

Fortunately, there is a League of Legends Wiki which has all the data I need in their specific champion pages, which they keep updated per patch. So I was wondering if there was any way to get the data from the divs in the wiki, and have it display on my site. What I want to do in my website is that whenever someone types a champion's name (in a post or whatever), I want it to display a hover-over dialog with some of the champions details. And a lot of other features such as that.

In plain English I need a way to :
> Tell PHP to go to the wiki's source code on a specific page
> Find a specific div container
> Get X data from there
> Pass X data into a function to display the hover-over

I think this way, I would not have to maintain a database as I can leech off the wiki's data.
I have not coded anything like this before, so I would like a few pointers as to how to achieve this. Any help will be appreciated!

I tried searching on google but couldn't find any relevant information, please redirect me to relevant source or help me with the code.

I want to pass a domain name in text field which will be scanned and then the script will display entire site map.

Not external links or links on a page. Sorry it is not easy for me to explain.

Eg. if i pass abc.com

Script will display

abc.com/12/adn.php
abc.com/asd/asd/
etc

Whatever their url format is.

All the links on that domain.
