PHP OCIi 12c XAMPP Configuration

Resolve it by following these steps: Make sure you download and install Oracle instantclient at: http://www.oracle.com/technetwork/topics/winsoft-085727.html, but note: Take note of your Oracle database version; use Version 12.1.x for Oracle Database 12c and Version 11.1.x for 11g releases. In either case, make sure you download the Basic Lite version of the Oracle instantclient. After that, do add the location of your Oracle instantclient to your System variable Path under your Environment Variables. Do equally ensure that you have both the PHP of your xampp and its extavailable and set there as well (if not, do add them). Then, proceed to add a new System variable with TNS_ADMIN as a variable name and the location to Oracle instantclient as the variable value. Also, define your User variables PATH with the same the location to Oracle instantclient as value. After this stage, restart your computer for a full propagation of the newly defined environment variables. Once on, you may open your Windows Command Prompt and run where oci* to ensure that you had your environment variables well defined; the response should look like this: C:\Users\flex>where oci* C:\oraclexe\app\oracle\product\11.2.0\server\bin\oci.dll C:\oraclexe\app\oracle\product\11.2.0\server\bin\ocijdbc11.dll C:\oraclexe\app\oracle\product\11.2.0\server\bin\ocijdbc11.sym C:\oraclexe\app\oracle\product\11.2.0\server\bin\ociw32.dll C:\instantclient_11_2\oci.dll C:\instantclient_11_2\oci.sym C:\instantclient_11_2\ocijdbc11.dll C:\instantclient_11_2\ocijdbc11.sym C:\instantclient_11_2\ociw32.dll C:\instantclient_11_2\ociw32.sym If not, you must have missed something and need to revisit the process, ensuring to completing it effectively. You may now proceed to your php.ini file (provided environment variables are well defined) and enable your oci extensions (php_oci8.dll and php_oci8_11g.dll) by uncommenting them; you can achieve that by simply removing the semi column (;) before the said extensions. Do remember to save your php.ini file, then, restart or start your Apache if it isn't already running. To check your PHP oci8 configurations are enabled, you may go back to your Windows Command Prompt and run: php --ri oci8; the response should be similar to the one below: C:\Users\flex>php --ri oci8 OCI8 Support => enabled OCI8 DTrace Support => disabled OCI8 Version => 2.1.1 Revision => $Id: 86f22a208f89dcd5b305e82929a7429683968b11 $ Oracle Run-time Client Library Version => 11.2.0.4.0 Oracle Compile-time Instant Client Version => 10.2 Directive => Local Value => Master Value oci8.max_persistent => -1 => -1 oci8.persistent_timeout => -1 => -1 oci8.ping_interval => 60 => 60 oci8.privileged_connect => Off => Off oci8.statement_cache_size => 20 => 20 oci8.default_prefetch => 100 => 100 oci8.old_oci_close_semantics => Off => Off oci8.events => Off => Off Statistics => Active Persistent Connections => 0 Active Connections => 0 Alternatively, you can create a PHP file with as<?php phpinfo(); ?> content, then open it in your browser and search for oci8 occurrences; it should show enabled there as well.
