Description:
------------
I have PHP 5.6.32 , Apache/2.4.29 (Unix), instant client 12_1 and OCI8 oci8-2.0.12. 

I used this manual http://php.net/manual/en/oci8.installation.php and steps: "For a manual install when the pecl command is not available, download the PECL OCI8 package"

After .configure and make and make install , I start apache and in error log I see this : 

PHP Warning:  PHP Startup: Unable to load dynamic library '/opt/freeware/lib/php/modules/oci8.so' - rtld: 0712-001 Symbol compiler_globals was referenced\n      from module /opt/freeware/lib/php/modules/oci8.so(), but a runtime definition\n\t    of the symbol was not found.\nrtld: 0712-001 Symbol executor_globals was referenced\n      from module /opt/freeware/lib/php/modules/oci8.so(), but a runtime definition\n\t    of the symbol was not found.\nrtld: 0712-001 Symbol core_globals was referenced\n      from module /opt/freeware/lib/php/modules/oci8.so(), but a runtime definition\n\t    of the symbol was not found. in Unknown on line 0

I have exported all needed Oracle environment variables in apache envvars.

Seems you're trying to load a non thread-safe extension into a
thread-safe PHP.  See the manual on how to properly build:
<http://php.net/manual/en/install.pecl.phpize.php>
<http://php.net/manual/en/install.pecl.static.php>

I configured the oci8.so now with 
./configure .......................

-same problem

Also tried to install with pecl/pear. Same result, same error.

How can i force to be "thread safe" oci8 extension?

phpize && ./configure … && make
 [2018-07-23 12:52 UTC] l dot strala at t-systems dot com

Assigning this to Christopher, perhaps Oracle got an idea (given it is AIX, which I remember having some interesting build issues throughout the years together with PHP)

- Make sure PHP command-line works first.

- Please post to https://community.oracle.com/community/database/developer-tools/php until we determine there actually is a bug.  Post more details such as exactly what you put in envvars.

PHP in command line works probably. Also OCI8. When I create simple phpinfo, and then php it in console then it shows info about OCI8. But when I open that php in browser it doesnt shows OCI8. Its interesting.

I'll assume you tested OCI8 in command line PHP and it works.

You need to make sure you are setting all required Oracle environment variables for Apache, make sure you are using the right syntax, and/or need to find a different way to pass the Oracle environment variables to Apache.  Setting the environment is a common problem but has various solutions depending on OS and Apache version.

I don't know about AIX, but on RH Linux, adding variables to /etc/sysconfig/httpd is the way to go.  You may or may not need to 'export' them. They may or may not expand environment variables on the right hand side of the '='.

I'll close this.  Follow up on OTN if you have further questions.
