Installing Oracle in WAMP environment

Installing Oracle in WAMP environment

Installing Oracle in WAMP environment
Download Oracle Express Edition (Free download) from the link.
Download Oracle SQL Developer which is a free download too from the link below:
If you dont have any experience working with Oracle SQL Developer, you can read this article
Install wamp server 2.5
enable php_oci8.dll extension in php modules
You need to download “Instant Client Downloads for Microsoft Windows (32-bit)“. Download Version Instant Client Package from the link above.
Place the files in any directory eg: C:\WampDeveloper\Tools\Oracle\instantclient_11_2
Then modify the System’s PATH environmental variable with the end location. This is important as otherwise its DLLs (OCI.dll) will not be found/loaded by PHP’s php_oci8_11g.dll: C:\WampDeveloper\Tools\Oracle\instantclient_11_2
Restart the wamp server.
Try this in any php code file for testing of oracle & php database connection.

if ($conn = oci_connect('hr', 'hr', '//localhost/xe'))
    //print 'Successfully connected to Oracle Database!';
    $errmsg = oci_error();
    print 'Oracle connection failed, Please check username, password and service name in oci_connect: ' . $errmsg['message'];

You can use hostname “//localhost/xe” or “(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))(CONNECT_DATA=(SID=xe)))” in the connection statement.
I had an inspiration from this article
