PHP: Unable to load dynamic library 'php_oci8.dll' , the procedure entry point ocilobread2 could not be located

Situation:

The Apache service wasn't starting

in the Apache error.log file I was getting the following error:

"Warning: PHP Startup: Unable to load dynamic library 'C:/php/ext/php_oci8.dll' - The specified procedure could not be found. \r \n in Unknown on line 0"

the I tried to execute from windows console the php command and I got the following error in an emerging window:

"the procedure entry point ocilobread2 could not be located in the dynamic link library oci.dll"

And also, in the PHP console, I got the error that I mentioned in the beginning of this post : "... Unable to load dynamic library .... "

Solution:

- download and unzip instantclient_10_2

- set PATH variable with the instantclient_10_2 folder route ie (C:\instantclient_10_2) . Note: Is VERY important that the instantclient path must be added at beginning of PATH variable or VERIFY the PATH variable in order to avoid having other routes to a different instanclient.

- check up php command in console

- restart APACHE
