I installed Wamp  amp  expected everything to work out of the box  Not so  I have 2 Oracle clients on my x64 Windows machine  instant and full   If anyone else has a similar setup  the trick is to make sure the instant client is  a  in your Path environment variable and  b  precedes the full client in the Path variable  There s a really brief section on Windows here but it gave the answer

Alright  folks   First  use    lt  php  phpinfo      gt     and determine your PHP Version  located at the very top  e g  7 0 xxx  and also  your PHP Version architecture  x64 or x86 and also  Thread Safe or Not THread Safe  located in the first table as  Thread Safety     Disabled  obviously means  Not Thread Safe    It is absolutely critical that the following three pieces of software that you will need are    for the same major version of PHP  7 0 for 7 0 xxx  same version of Oracle as the version you are accessing  11g  12g  etc  the same Not Thread Safe   Thread Safe version of PHP all for the same architecture    If any of the following are for a different architecture  Not Thread Safe Thread Safe version  PHP major version number  or database version  you ll get errors    1  PHP for Windows  2  OCI8 PECL Drivers for PHP  https   pecl php net package oci8   3  Oracle Instant Client   Remember  If you are connecting to an 11g Oracle instance  you need an 11g driver   Second  install the correct PHP  OCI8 PECL Driver  and instant client   I chose   d  php  for php d  oci  for instant client unzip the contents of the OCI8 PECL Driver into d  php ext    Third  modify d  php php ini according the instructions given by Oracle   1  set the extension directory 2  set only one of the following    a  for 11g drivers  use extension php oci8 11g dll   b  for 12c drivers  use extension php oci8 12c dll   c  for other oracle DB drivers  use the correct oracle extension    Fourth  Add d  oci   or whatever your instant client install location is  to your system PATH   Fifth  reboot your PC   Sixth  on a command prompt  type  where oci   and verify that your Instant Client install path version of oci dll is present   Seventh  go to d  php  and type  php -m  and you should see OCI8 in the list   If you do not see OCI8 in the list of modules after typing  php -m   open up d  php errorlog txt  If you see something like   PHP Warning   PHP Startup  Unable to load dynamic library  ext php oci8 11g dll  -  1 is not a valid Win32 application    then either instant client or your PECL driver download is not the same architecture as your PHP version   If you see something like   PHP Warning   PHP Startup  Unable to load dynamic library  ext php oci8 12c dll  - The specified procedure could not be found    then you are using the wrong OCI8 PECL driver for your version of instant client   Hope this helps

I installed WAMPServer 2 5  32-bit  and also encountered an oci connect error  I also had Oracle 11g client  32-bit  installed  The common fix I read in other posts was to alter the php ini file in your C  wamp bin php php5 5 12 directory  however this never worked for me  Maybe I misunderstood  but I found that if you alter the php ini file in the C  wamp bin apache apache2 4 9 directory instead  you will get the results you want  The only thing I altered in the apache php ini file was remove the semicolon to extension php oci8 11g dll in order to enable it  I then restarted all the services and it now works  I hope this works for you
