Connect to Mssql 2008 sever remotely through php - php

Quick question: I am having issues while trying to connect to a mssql 2008 server through php. The php script is located on a different server. Does the mssql server have to have php installed on it? or only the server which I am running the script from?

Only the server you are running PHP on. If there's a connection error, you may be having issues with you connection string or with the raw networking (for instance, the port you are trying to connect to is blocked on the remote server).

If you take a look at the documentation for mssql in PHP, you can see that it accepts both local and external addresses (computer or server, port).
The server running mssql, to which you're connecting, doesn't need PHP enabled.

PHP: Connecting PDO to SQL Server

I know that there is some discussion on PHP & SQL Server, but most of this is a few years old, and predates PHP; not much mentions PDO either.
I have a client who wants to access their SQL Server database from their web server. The Web Server is Apache running on Ubuntu Linux, while the SQL Server is running on a separate Windows box.
Most of what I have been able to find is dated, especially since PHP 7 came out.
What do I need to install to get PHP & PDO connecting to to a remote SQL Server?

Connection error to sql server when doing massive queries with sqlsrv

i was wondering if anyone knows why i am getting the following error.
I have an application doing massive queries to a SQL 2008 Server. The main application runs over PHP on linux , I call many php scripts simultanously to a windows server running PHP over xampp, this server queries the sql database and this is where I am getting the error.
On this windows server I hava PHP 5.4.4 with the sqlsrv extension. I have the sql server configured to handle unlimited connections. however when I send many API calls (thousands) i eventually start getting connection errors like the one below,
Unable to connect to server
I read that mssql conection can be tuned with the max_procs config, however I am using sqlsrv extension instead and I havent found any info regarding this .
Has anyone experienced this issue before.
Thanks in advanced.

MySQL Workbench 5.6 crashes on connection to localhost

I'm running Apache 2.2 and MySQL Workbench, and using PHP to access the database.
The problem is, when I try to open the database I've made, MySQL Workbench can't seem to connect to the localhost at port 80, and the program stops responding.
How can I fix this?
Update: After some time of the program simply not responding, it gave me this error message:
"Unhandled exception: Lost connection to MySQL server at 'waiting for initial communication packet', system error 10060 (code 2013)"
A wamp installation has a lot of issues. Instead, you can run a Virtual Machine with ubuntu and run there LAMP. it is way more reliable than running wamp that is not supposed to be "equal" in terms of your production environment - that for sure is linux based OS. Also, keep in mind that programs such skype blocks the port 80 and 443. Search what programs are using the port for mysql... that's why I don't develop AMP apps under windows, but under linux.

ADO and msqli connections very slow

I am experiencing a very slow ADO and mysqli connection for my production web server. The current software setup is windows 2008 server R2 Standard Edition SP1, Apache 2.4, PHP 5.3.10, MySql 5.5.24, Pear 1.94, Zend Engine version 2.30.
I've profiled the code using XDEBUG and it shows the initial connections taking around 1200ms each (regardless of page being visited), whereas on my local development machine and another test server the connections only takes around 8ms. The code for the website is all in sync through SVN except for the php, pear, mysql, and apache ini and conf files. I've done diffs on these to check for differences and there aren't any. The DB contents are a complete copy as well. Everything for the production server is hosted on the same machine so there aren't any firewall or internet issues.
The first connection profile has the following call stack:
ADOConnecton->Connect
ADODB_mysql->_connect
php::mysql_connect
The second one:
php::mysqli->mysqli
Any suggestions?
Usually the slowness in (first) connection depend on DNS resolution.
May be:
client to resolve the server name
server to resolve the client name to match an access rule
let the client/server let know the server/client address using the host file:
http://en.wikipedia.org/wiki/Hosts_(file)
I edited the Mysql my.ini to change the mysql service to only bind to the IPV4 loopback adapter.
[mysqld]
...
bind=127.0.0.1
I also changed the \public_html\conf\face.ini to use the IPV4 loopback address instead of local host. (Changed "localhost" to "127.0.0.1")
After that all issues went away. I'm not sure if it is because the machine has a half dozen IP addresses or its trying to decide whether to use IPV6 or IPV4.

Connecting to external MySQL DB from a web server not running MySQL

While I've been working with MySQL for years, this is the first time I've run across this very newbie-esq issue. Due to a client demand, I must host their website files (PHP) on a IIS server that is not running MySQL (instead, they are running MSSQL). However, I have developed the site using a MySQL database which is located on an external host (Rackspace Cloud). Obviously, my mysql_connect function is now bombing because MySQL is not running on localhost.
Question: Is it even possible to hit an external MySQL database if localhost is not running MySQL?
Apologies for the rookie question, and many thanks in advance.
* To clarify, I know how to connect to a remote MySQL server, but it is the fact that my IIS web server is not running ANY form of MySQL (neither server nor client) that is giving me trouble. Put another way, phpinfo() does not return anything about MySQL. *
Yes, you can use a MySQL database that's not on the same machine as Apache+PHP.
Basically, you'll connect from PHP to MySQL via a network connection -- TCP-based, I suppose ; which means :
MySQL must be configured to listen to, and accept connections on the network interface
Which means configuring MySQL to do that
And given the required privileges to your MySQL user, so he can connect from a remote server
And PHP must be able to connect to the server hosting MySQL.
Note, though, that habing MySQL on a server that's far away might not be great for performances : each SQL query will have to go through the network, and this could take some time...
If phpinfo is not returning anything about MySQL you need to install the MySQL plugin for PHP, easiest way to do that probably is to just upgrade PHP to the latest version. If not there is a .DLL file that you will need.
http://www.php.net/manual/en/mysql.installation.php
you will need to install the mysql extensions. this link should help: http://php.net/manual/en/install.windows.extensions.php
The MySQL server has nothing to do with PHP itself. What "mysql support" in PHP means is that it's been compiled with (or has a module loaded) that implements the MySQL client interface. For windows, it'd be 'mysql.dll', and on Unix-ish systems it'd be 'mysql.so'. Once those are loaded, then the various MySQL intefaces (mysql_xxx(), mysqli_xxx(), PDO, MDB2, etc...) will be able to access any MySQL server anywhere, as long as you have the proper connection string.
