I have a file called PhotoGallery.sdf and was wondering how to connect to this db with php, or if it is even possible?
Maybe point me to the right documentation. I found query strings for this, but not a db connect string...

I have been developing a plugin for Wordpress and I am stuck at point where I have to connect my plugin to a database remotely.
I know the procedural way of estabilishing the connection to a database which looks something like this $link = mysqli_connect("hostname", "username", "password", "database");
The $link variable will either return true or false depending on connection status, in my case the plugin is not allowed to connect to my MySQL server due to Administrator restrictions.
I have few questions regarding this.
What do you do in cases like these? If one enables the access via MySQL dashboard on a single database to make the connection, would that make a database vulnerable to injections or less protected?
If the previous is the right way, how do you pass the parameters properly to a function without revealing the plain credentials?
Is there any other way to implement this logic to get the needed data that plugin requires?
P.S. I have already tried looking up here for an answer without luck, the PHP documentation also did not help.
I have some doubts about connecting the database
how do i connect the PHP file with database(php my admin)?
what code should i give to check the correct and incorrect passwords?
how do i connect the database with my html page?
Actually i had tried a lot of programs to connect them, But in vain.
I have completed the layouts. Just the database connectivity is pending.
You must first make an acc on phpmyadmin and the connection shoul be like this:
$con=new mysqli("localhost","yourusername","yourpass","the database u want to work on");
This is the connection to a db.
I think u dont know php and thats why are u asking. U better learn and read about this. Check www.w3schools.com for php lessons.
I would like to create a website that shows analysis of my Odb database. Therefore I need to extract data from orientdb, in a "live way" i.e connect and open the database via php, query my database and stock into variables the results. I found one API written in php that is supposed to stream data from Odb but it's not working.
Do you know if there is any way to do like the php command mysqli (that connect to mysql and allows you to query the database) but with orientDb ??
Thank you
I hope will be of help, to these two links:
OrientDB-PHP
Graph-in-php-through-OrientDB
the guides are shown to connect to OrientDB via php.
So I'm brand spanking new to mysql and php.
I'm set up with Mysql workbench and I'm practicing building a site using Notepad++ and just run it through Chrome. All I want to do is create a sign up page, which I'm assuming I use a .php page on the site, where it would be a username and password. That's it. I can't seem to find any tutorials on how to connect mysql to the .php page, or how to create a sign in page. Any help would be appreciated!
Welcome to PHP!
Typically a connection is established on a PHP page with something along the lines of this:
$conn = mysqli_connect("localhost","[username]","[password]","[databasename]") or die("Error " . mysqli_error($conn));
The "or die" will produce an error if there's a problem establishing a connection. Also, this uses the newer "mysqli_" method for connection; make sure when you call this connection in future that you use mysqli_ methods (there are still traditional "mysql_" methods available, but are depreciated).
Hope this helps!

I would like to clear my doubts in hooking up of MySQL database with XCode.
My application would need to retrieve data from MySQL as there would be a login screen.
As such, in order for me to retrieve data from my database, there is a need for me to create a database using MySQL and connect it using PHP and then connect PHP to XCode?
I am a greenhorn in application developing but I am tasked to do it for my school.
I would need great help in creating a PHP in connecting MySQL(it would be good if its steps-by-steps guide). I would really truly appreciate your kind generous reply.
Thank you in advance!
It is very simple to connect to a MySQL database with PHP. There are a couple of APIs for this, mysql and mysqli. Mysqli is probably the better one to use, but mildly denser. The Mysql one works like this:
$db = mysql_connect("host:port", "username", "paswword");
mysql_select_db("my_db", $db);
# say we want to select everything from the table Persons
$result = mysql_query("SELECT * FROM Persons");
while ($row = mysql_fetch_array($result))
{
# do your magic
# columns are accessed in a zero based array
# such as $row[0], $row[1], etc.
# look at mysql_fetch_assoc to see how to access
# using the column names
}
mysql_close($db);
There's what looks like an older but still valid W3c tutorial here and the MySQL PHP API reference there. To learn about the API differences read the Overview of the MySQL PHP drivers.
As the other answers have stated you'll want the PHP to output something like JSON or XML to communicate with your app and the XCode.
This tutorial follows the whole process through step by step from creating a web service to implementing the web service in your app. I found it super easy to follow.

It sounds like you need some sort of WebService. What you can do is just create your PHP pages and let them output a set format (say JSON or XML). Then in your Obj-C application just do the webrequests and parse the results.
There might be some existing solutions which you can use, Webservice is the keyword here.
Here what sounds better to connect to a mysql database, your best bet is to use JSON/SOAP/XML/PHP websevices to talk between your database and your app..
The reason database connection directly from the device is a bad idea, is that you have to enable global external access to it for it to work. You can keep your data safer by having scripts on your server do the communication to the database.
One example of how to do this is create PHP pages that export XML data as your mysql data export , and use GET POST methods to post data to PHP pages to write to your database..
