WampServer

hello,
In order to access an oracle database from php, I had to activate the extension php_oci8_12c. But when I do, it does not appear in the phpinfo ().
On the other hand, I get in the php logs the error message
[13-Jan-2017 08:39:48 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'c:/wamp64/bin/php/php7.0.10/ext/php_oci8_12c.dll' -% 1 is not a Valid win32 application

thank you,

Did you also install the Oracle Client software. The PHP php_oci8_12c.dll is only and interface between PHP and the Oracle Client software that must be installed on your PC as well.

I just installed the oracle instant. but now, i have this error message when i start wamp
"The procedure entry point OCILobRead2 could not be located in the dynamic link library OCI.dll"
and then
""php Startup: Unable to load dynamic library 'c:/wamp/bin/php/php5.5.12/ext/php_oci8_11g.dll' - The specified module could not be found"

ps: i also changed my wamp version to wamp 2.5 32 bit

Did you load the Oracle12 client or the Oracle8 Client?

Oracle11,

I finally found what was wrong

May be a conflict issue between the Oracle clients on my machine. AnyWay, to solve the problem, I changed the position of Oracle Instant Client in the PATH to put it at the beginning of chain
