This is a crucial piece of information for SYBASE users:
If you are using the free, but old, 11.x client libs from sybase,
then compile with option "--with-sybase-ct=$SYBASE"
substitute $SYBASE with the appropriate directory name.
option --with-sybase (without ct) can somehow be used to talk to old MS-SQL servers, but only with the 11.x client libs.
If you are using free, or have legally obtained, 12.x client libs from sybase, then compile with option "--with-sybase-ct=$SYBASE/$SYBASE_OCS"
substitute $SYBASE/$SYBASE_OCS with the appropriate directory name.
Database issues
This section holds common questions about relation between PHP and databases. Yes, PHP can access virtually any database available today.
- I heard it's possible to access Microsoft SQL Server from PHP. How?
-
On Unix machines you can use PDO_ODBC or the Unified ODBC API.
On Windows machines you can also use PDO_SQLSRV or SQLSRV.
Also see the answer to the next question.
- Can I access Microsoft Access databases?
-
If you are running PHP on a Unix box and want to talk to MS Access on a Windows box you will need Unix ODBC drivers. » OpenLink Software has Unix-based ODBC drivers that can do this.
Another alternative is to use an SQL server that has Windows ODBC drivers and use that to store the data, which you can then access from Microsoft Access (using ODBC) and PHP (using the built in drivers), or to use an intermediary file format that Access and PHP both understand, such as flat files or dBase databases. On this point Tim Hayes from OpenLink software writes:
Using another database as an intermediary is not a good idea, when you can use ODBC from PHP straight to your database - i.e. with OpenLink's drivers. If you do need to use an intermediary file format, OpenLink have now released Virtuoso (a virtual database engine) for NT, Linux and other Unix platforms. Please visit our » website for a free download.
One option that has proved successful is to use MySQL and its MyODBC drivers on Windows and synchronizing the databases. Steve Lawrence writes:
- Install MySQL on your platform according to instructions with MySQL. Latest available from » http://www.mysql.com/ No special configuration required except when you set up a database, and configure the user account, you should put % in the host field, or the host name of the Windows computer you wish to access MySQL with. Make a note of your server name, username, and password.
- Download the MyODBC for Windows driver from the MySQL site. Install it on your Windows machine. You can test the operation with the utilities included with this program.
- Create a user or system dsn in your ODBC administrator, located in the control panel. Make up a dsn name, enter your hostname, user name, password, port, etc for you MySQL database configured in step 1.
- Install Access with a full install, this makes sure you get the proper add-ins... at the least you will need ODBC support and the linked table manager.
- Now the fun part! Create a new access database. In the table window right click and select Link Tables, or under the file menu option, select Get External Data and then Link Tables. When the file browser box comes up, select files of type: ODBC. Select System dsn and the name of your dsn created in step 3. Select the table to link, press OK, and presto! You can now open the table and add/delete/edit data on your MySQL server! You can also build queries, import/export tables to MySQL, build forms and reports, etc.
Tips and Tricks:
- You can construct your tables in Access and export them to MySQL, then link them back in. That makes table creation quick.
- When creating tables in Access, you must have a primary key defined in order to have write access to the table in access. Make sure you create a primary key in MySQL before linking in access
- If you change a table in MySQL, you have to re-link it in Access. Go to tools>add-ins>linked table manager, cruise to your ODBC DSN, and select the table to re-link from there. you can also move your dsn source around there, just hit the always prompt for new location checkbox before pressing OK.

To enable SQL Server access from ubuntu 16.04:
* Run these commands:
```
sudo curl https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
curl https://packages.microsoft.com/config/ubuntu/16.04/prod.list > mssql-release.list
sudo mv mssql-release.list /etc/apt/sources.list.d
sudo apt-get update
sudo ACCEPT_EULA=Y apt-get install msodbcsql unixodbc-dev
sudo apt-get install php7.1-dev
sudo apt-get install autoconf
sudo pecl install pdo_sqlsrv-4.1.6.1
```
* Confirm ODBC driver installation:
```
odbcinst -q -d -n "ODBC Driver 13 for SQL Server"
```
* Update the php.ini file: run` php --ini` to find the path to your php.ini file
* Add this line to /path/to/php.ini
```
extension=pdo_sqlsrv.so
```
* Run `php -i` to confirm SQLSRV support was added
* NOTE: extensions (on my computer) were installed here:
`/usr/local/lib/php/extensions/no-debug-non-zts-20160303/`
* Test user access directly on the Windows server running MSSQL:
```
sqlcmd -S ip_address -U username -P password -d database -q "select * from table_name"
```
* On the Windows server: open port 1433 in your firewall
* Install the FreeTds utils to test the connection:
```
sudo apt-get install freetds-bin
tsql -H mssql.host.ip.address -U username -P password -D database -p 1433
```
* Formulate the correct DSN (Data Source Name):
See: http://php.net/manual/en/ref.pdo-sqlsrv.connection.php
* Sample PHP Code:
```
<?php
// Database params
$tcp = '192.168.3.126';
$port = 1433;
$user = "test";
$password = "Password123";
$database = "test";
// Open connection
try {
// Database connect -- use one of the two statements below
$dsn = 'sqlsrv:Server=tcp:' . $tcp . ',' . $port . ';Database=' . $database;
$dbh = new PDO( $dsn, $user, $password, array());
// SQL prepare
$sql = "SELECT * FROM prospects";
$sth = $dbh->prepare($sql);
// Execute
$sth->execute();
// Fetch results
$row = $sth->fetch(PDO::FETCH_ASSOC);
if ($row) {
$output = '<pre>';
$output .= implode("\t", array_keys($row)) . PHP_EOL;
$output .= implode("\t", $row) . PHP_EOL;
while ($row = $sth->fetch(PDO::FETCH_NUM)) {
$output .= implode("\t", $row) . PHP_EOL;
}
}
} catch (PDOException $e) {
$output .= $e->getMessage();
}
$output .= '</pre>';
echo $output;
```
