# Connecting To an Oracle DB with PHP

Posted on 2009-07-08

Hello,

I'm trying to connect to a oracle database using PHP.  I have already enable the extension OCI8 and tried to connect. However when I try to connect I get the error message:

Fatal error: Call to undefined function oci_connect() in C:\wamp\www\test\connection2.php on line 15

Below is the code I'm using to connect. For some reason, i think Its not recognizing the OCI. If anyone see anything wrong with my code please let me know thanks.
$c = oci_connect("username","password","localhost/xe");  0 Question by:Robert Thomas [X] ###### Welcome to Experts Exchange Add your voice to the tech community where 5M+ people just like you are talking about what matters. • Help others & share knowledge • Earn cash & points • Learn & ask questions • 3 • 3 6 Comments LVL 9 Expert Comment ID: 24811952 Are you sure you enabled the Oracle extension. Can you try do get the results from phpinfo() from your server? To do this: - Create a new php file - Put in the code below - Open the php file through your webserver in a brwoser <?php phpinfo(); ?>  0 LVL 9 Expert Comment ID: 24811987 If it is enabled you should get something like: OCI8 Support => enabled Version => 1.2.4 Revision =>$Revision: 1.269.2.16.2.38 $Active Persistent Connections => 0 Active Connections => 0 Oracle Version => 10.1 Compile-time ORACLE_HOME => /ORACLE/app/oracle/product/client Libraries Used => Temporary Lob support => enabled Collections support => enabled If it's not enabled you should check if you've edited the right php.ini file. If everything is ok try the code below to create a testpage to see if the connection succeeds. I see that you're using "localhost/xe" in your connection. Try to use the local ip address "127.0.0.1" to connect. Windows might create problem by using the value "localhost". <?php if ($conn = oci_connect('hr', 'hr', '//127.0.0.1:1521/xe')) {
print 'Successfully connected to Oracle Database XE!';
oci_close($conn); } else {$errmsg = oci_error();
print 'Oracle connect error: ' . \$errmsg;
}
?>

I think I properly enable oci8. But its not showing on the information page. I went into the php.ini file and enable it in the the extension area by taking away the ";".  But I just found the OCI8 section below. Probably a stupid question, but do I need to un-comment and enable all the scripts in that section?

If the extension is not showing on the info page than you did not enable it. You probably have multiple php.ini  files.
Can you search your server/computer for the php.ini files.

If you want to set different settings like max connection etc then you can enable th settints in the OCI8 section.

I've checked there appears to be only one.  The only place oci8 appears in the php info in the configure command:

cscript /nologo configure.js "--enable-snapshot-build" "--enable-debug-pack" "--with-pdo-oci=C:\php-sdk\oracle\instantclient10\sdk,shared" "--with-oci8=C:\php-sdk\oracle\instantclient10\sdk,shared"

Is there any possible way that the extension could be blocked by another extention?

I had to edit the the system path and install the system client before the oci8 extension could be used.
