PHP read remote database transfer speed problem?

I now have some pages to hang on to someone else's website, and then to read data from my database to those pages display, if the direct mysql_connect () connection to read the data will not be very slow? Will there be a big problem? Because you also want to buy items on those pages, and then jump to our back-office payment ...

Test it and you'll know.

It is not recommended to do so. Let him host the server in your same network section of the machine room. Make the server an intranet data, then two front-end read the intranet data server data

Remote operation must be slower, that's all.
The problem is that remote operations require open access, with a slight careless exposure of your data to each other.
This should not be what you want, because there are still payments to our backstage

Hello ·
So, we have a shopping backstage, but the front-end want to put on the co-operation of the site (there may be multiple sites), and then on the cooperation of the site has a number of separate pages dedicated to our site products, and then click on the purchase jumped to us to pay the deal.
Do you think such an idea is realistic, good to achieve it? Is the main security this piece of difficulty is not very high?

If it is through someone else's website to hang their own things, just make a link, in fact, nothing, if it involves payment or something, or cautious point good.

I understand what you mean, you want to put the merchandise on your platform on the other merchant's website. In fact, you do not need to open MySQL permissions, because the other people have access to the database is not safe for you.
You can learn about other ways of interacting with data, such as XML or webserver, and you provide them with an interface that is much better than the permissions you give them directly to their database operations.

If it is not the same engine room, under the same switch, the speed is very slow, the best way is to do an API interface to each other to let the other side to tune
