Because xampp does not have 64bit version for window
So, here is the solution to resolve some issues below:
1. Warning: PHP Startup: Unable to load dynamic library 'D:\xampp\php\ext\php_oci8.dll' - %1 is not a valid Win32 application.
2. PHP Startup: Unable to load dynamic library 'D:\xampp\php\ext\php_oci8.dll' - The specified module could not be found.
Solution:
1. Download oracle instanceclient 32bit
http://www.oracle.com/technetwork/topics/winsoft-085727.html
(instantclient-basic-nt-12.1.0.2.0.zip)
2. Extract instantclient (Ex: D:\instantclient_12_1)
3. Configure Windows PATH environment variable, add more:
D:\xampp\php\ext;D:\instantclient_12_1
4. Configure php.ini, enable extension php_oci.dll
extension=php_oci8.dll (remove ; character)
Note: check your oracleclient version (11g, 12c, ...), if cannot enable php_oci8, try to download files from here: http://windows.php.net/downloads/pecl/releases/oci8/2.0.8/php_oci8-2.0.8-5.6-ts-vc11-x86.zip
extract those files to xampp/php/ext/ folder, then restart apache again
5. Restart xampp or restart PC (if necessary)
6. Check again
C:\Users\namdt5>php -m | find "oci"
oci8
Done.
