Now a day, many PHP applications have been developed keeping Oracle as database instead of MySQL and it’s a very common problem for those, using Oracle 11g in Windows 7 (64-bit) with PHP applications that the connection of Oracle database has been refused to connect. Here I have used Instant Client to connect Oracle database with my PHP application.
Instead of using separate installation of PHP and Apache, I have used here WAMP server. Just follow the step-by-step to connect Oracle database with PHP applications on the platform of Windows 7 (64-bit).
STEP 1. Install WAMP server and Oracle 11g at first.
STEP 2. For Windows 7 (64-bit), extract instantclient-basic-windows.x64-184.108.40.206.0.zip, downloaded from http://www.oracle.com/technetwork/topics/winx64soft-089540.html to C:\Windows\SysWOW64\instantclient_11_2 and set it on PATH variable for Environment variable.
STEP 3. Reboot the system now.
STEP 4. Allow PHP extension from php.ini as
extension=php_oci8_11g.dll (just remove the ";" from the start of the line)
STEP 5. Restart WAMP server.
STEP 6. Open the file to see the database name as D:\app\Farhan\product\11.2.0\dbhome_1\NETWORK\ADMIN\tnsnames.ora
LISTENER_ORCL = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) ORACLR_CONNECTION_DATA = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521)) ) (CONNECT_DATA = (SID = CLRExtProc) (PRESENTATION = RO) ) ) ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl.168.1.2) ) )
Here, the service name is found as "
STEP 7. Make the connection in PHP script as
oci_connect(your_username, your_password, "localhost/orcl.168.1.2");
