Why there is nothing about oci8 in phpinfo() for oracle database connections once oci8 has been installed?

Hello everybody,

 

 

I'm trying to setup a connection from PHP to an oracle database by using OCI8. According to the documentation, upon a successfull installation, I'm supposed to see some information about OCI8 in phpinfo().

 

Problem: Nothing shows up in phpinfo about OCI8

 

Just to see what would be the output I run the very same PHP test script in the article

 

<?php

    $conn = oci_connect('myuser', 'mypassword', 'localhost/DB01');

    $stid = oci_parse($conn, 'select table_name from user_tables');

    oci_execute($stid);

    echo "<table>\n";

    while

        (

            (

                $row =

                    oci_fetch_array

                    (

                        $stid, OCI_ASSOC+OCI_RETURN_NULLS

                    )

            )

            != false

        )

    {

        echo "<tr>\n";

        foreach ($row as $item)

        {

            echo "  <td>".

                ($item !== null ? htmlentities($item, ENT_QUOTES) :

                    " ")."</td>\n";

        }

        echo "</tr>\n";

    }   

    echo "</table>\n";

?>

 

And the output was

 

 

Fatal error: Call to undefined function oci_connect() in /var/www/html/myscript.php on line ...

 

Which shows that something serious is missing.

 

As a result, I would like to ask you to kindly take a look to the below details about how I proceeded in order to setup OCI8 and to see where I made mistake(s)

 

 

Here are some details about my working platform

 

OS: Linux Fedora Core 17 (64 bits)
 
DBMS: Oracle Enterprise Edition 11gR2 (11.2.0.1.0)
 
PHP Version: 5.4.13
 
Apache version: 2.2.23

 

 

I installed OCI8 based on the following article (except that I already had both server and client installed on the same physical machine, therefore I didn't need to install/reinstall the instant client)

http://www.oracle.com/technetwork/articles/technote-php-instant-084410.html

 

So being as ROOT I run the following

 

# pecl install oci8

Which gave me the following output

# pecl install oci8

So looking at the above bold output, I think we can say that there is however some link between the installed oci and my oracle server.

 

Also, I added to the /etc/sysconfig/httpd configuration file the following environment variables which had already been defined in ~/.bash_profile

 

# Configuration file for the httpd service.

#
# Note: With previous versions of httpd, the MPM could be changed by
# editing an "HTTPD" variable here.  With the current version, that
# variable is now ignored.  A particular systemd service must be
# chosen corresponding to the desired MPM:
#
#   httpd.service         => prefork MPM
#   httpd-worker.service  => worker MPM
#   httpd-event.service   => event MPM
#
# Use systemctl to stop/start between MPMs, and to disable/enable
# whichever service is required to start at boot time.
#

#
# To pass additional options (for instance, -D definitions) to the
# httpd binary at startup, set OPTIONS here.
#
#OPTIONS=

#
# This setting ensures the httpd process is started in the "C"
# locale by default:
#
LANG=C

 


PassEnv ORACLE_BASE
PassEnv ORACLE_HOME
PassEnv LD_LIBRARY_PATH64
PassEnv LD_LIBRARY_PATH
PassEnv TNS_ADMIN
PassEnv NLS_LANG
PassEnv ORACLE_SID

 

Once the variables were defined I restarted the httpd

 

 

service httpd restart

 

Yet, the same problem, no oci8 in phpinfo()

 

Could someone kindly make some clarification?

 

 

Thanks in advance,

Load up a page via your webserver that outputs phpinfo() and then look for the Loaded Configuration File entry. It's common that the webserver uses a different php.ini file than the CLI version of PHP. You will need to make sure you add the extension in both php.ini files.

Hello there,

 

 

Thank you very much for your attention to my problem.

 

First of all, after a bit googling I understood that the environment variables inside /etc/sysconfig/httpd as I specified by using PassEnv are those used internally by apache and have nothing to do with the OS environment variables. Apparently for OS environment variables the same syntax applies as ~/.bash_profile.

 

So instead of adding

PassEnv ORACLE_BASE
PassEnv ORACLE_HOME
PassEnv LD_LIBRARY_PATH64
PassEnv LD_LIBRARY_PATH
PassEnv TNS_ADMIN
PassEnv NLS_LANG
PassEnv ORACLE_SID

I added the following lines at the end of /etc/sysconfig/httpd

ORACLE_BASE=/u01/app/oracle
export ORACLE_BASE

ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export ORACLE_HOME

LD_LIBRARY_PATH64=$LD_LIBRARY_PATH64:$ORACLE_HOME/lib:$ORACLE_HOME/network/lib
export LD_LIBRARY_PATH64

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$LD_LIBRARY_PATH64
export LD_LIBRARY_PATH

TNS_ADMIN=$ORACLE_HOME/network/admin
export TNS_ADMIN

NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
export NLS_LANG

ORACLE_SID=db01
export ORACLE_SID

 

However, I'm not sure that these variables are actually being taken into account by Apache because when I restart the server, here is what I can read in the log file

# cat /var/log/httpd/error_log

#

Looking for the missing file

# locate libclntsh.so.11.1
/home/oracle/oracle_extract_folder/database/stage/ext/lib/libclntsh.so.11.1
/u01/app/oracle/product/11.2.0/db_1/inventory/Scripts/ext/lib/libclntsh.so.11.1
/u01/app/oracle/product/11.2.0/db_1/inventory/backup/2012-06-25_12-08-41PM/Scripts/ext/lib/libclntsh.so.11.1
/u01/app/oracle/product/11.2.0/db_1/lib/libclntsh.so.11.1

Yet /u01/app/oracle/product/11.2.0/db_1/lib/ is exactly what I specified as LD_LIBRARY_PATH in /etc/sysconfig/httpd. So it seems that (maybe) apache doesn't see my environment variables.

 

 

Load up a page via your webserver that outputs phpinfo() and then look for the Loaded Configuration File entry.

I proceeded accordingly as you said when I see the output of the phpinfo() in my browser

I have

 

Loaded Configuration File = /etc/php.ini

 

It's common that the webserver uses a different php.ini file than the CLI version of PHP

Very interesting, I didn't even know that there are two different php.ini files

However, it seems that on my system both of them point to the same file

 

# php -i | grep Configuration

Configuration File (php.ini) Path => /etc

Loaded Configuration File => /etc/php.ini

Configuration

#

 

I'm really confused !

Ok, I solved the problem.

 

It was SELinux which was blocking the library load. Now I have OCI8 entry in phpinfo(). At the same time as we saw before the PHP in command line could detect OCI8, maybe this means that SELinux doesn't have the same impact in CLI as in GUI.

I also wrote a test SQL script (SELECT employee_id FROM employees WHERE department_id = 100) and the result was printed on the screen perfectly.

So for those who may have encountered the same problem with the same environment parameters I'm going to give a summary of how I proceeded in the case where it might be helpful for others.

My environment
OS: Linux Fedora Core 17 (X86_64)
Oracle version: Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit
Apache version (httpd): Apache 2.0
PHP version: 5.4.13


Before the installation
Before the installation I disabled SELinux. At the time of writing I'm not an expert of SELinux so I don't know any rule modification in order to modify SELinux policy accordingly allowing to OCI8 module to load oracle libraries. As a result I finally disabled completely the SELinux on my system which may have serious security impacts! This can be done in the following way (being as root)
 

 

# vim  /etc/selinux/config
 

 

The file content is something similar to the following
 

 

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted
 

So what I did was that I put a comment at the beginning of the line SELINUX=enforcing and instead I added a new line right after that line which was SELINUX=disabled.

Finally I rebooted the system.


Installation:
- Make sure that all oracle environment variables are defined in ~/.bash_profile of the user who installs OCI8. Otherwise you will have to enter manually the path to $ORACLE_HOME. I tested both ways and each method works pretty well. Yet I find the first one more elegant because it detects automatically everything

- In my case, PHP, Apache and Oracle server were all on the same physical machine, therefore I didn't need to install the Oracle Instant client. All the required oracle libraries for OCI8 were therefore already available.

- being as ROOT, I run the following (I don't know whether this was mandatory but I prefered to stop httpd before installing OCI8)
 

 

# pecl install oci8
 

(On my machine pecl was already there, if not you can install it by using yum)

- Once installation is over, at the end of the installation report in the terminal you will get something like this
 

Build process completed successfully
Installing '/usr/lib64/php/modules/oci8.so'
install ok: channel://pecl.php.net/oci8-1.4.9
configuration option "php_ini" is not set to php.ini location
You should add "extension=oci8.so" to php.ini



The two bold lines above shows what you have to put in your php.ini file (on my computer this file is in /etc/php.ini)
So I updated the php.ini file in the following way:

 

;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Dynamic Extensions ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
 
; If you wish to have an extension loaded automatically, use the following
; syntax:
;
;   extension=modulename.extension
                       .
                       .
                       .
extension=oci8.so
                       .
                       .
                       .
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
; Paths and Directories ;
;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;
 
; UNIX: "/path1:/path2"
;
;
                       .
                       .
                       .
extension_dir="/usr/lib64/php/modules"
 

Then you have to define the required oracle environment variables for Apache. According to what I read in  http://www.oracle.com/technetwork/topics/php/underground-php-oracle-manual-098250.html and in several forums while I was googling for this problem and also based on my own tests, it seems to me that depending on which Apache version you're using, the syntax for declaring the environment variables in /etc/sysconfig/httpd is not the same.

Here is what I added at the end of the file /etc/sysconfig/httpd

 

.
.
.
ORACLE_BASE=/u01/app/oracle
ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/db_1/lib:/u01/app/oracle/product/11.2.0/db_1/network/lib
TNS_ADMIN=/u01/app/oracle/product/11.2.0/db_1/network/admin
NLS_LANG=AMERICAN_AMERICA.WE8MSWIN1252
ORACLE_SID=db01
 


I tried to use the export keyword before the variable names but it didn't work for me, yet I saw in other forums that there were people who apparently had used that syntax successfully. So again it is a matter of personal observation. For me using Apache 2.0, only the above syntax works. Also if I use $ in order to expand the environment variables it doesn't work
so for example instead of writing
 

 

ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME/network/lib
 

 

I had to write explicitly the expanded values myself, that is,
 

ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
LD_LIBRARY_PATH=/u01/app/oracle/product/11.2.0/db_1/lib:/u01/app/oracle/product/11.2.0/db_1/network/lib
 


Once this is done, restart httpd
 

# service httpd start
 


If everything went well, normally you will see the OCI8 entry if you run phpinfo() in a test PHP script.

Hope this may help others,

Dariyoosh
