Unable to load dynamic library 'php_oci8_11g.dll'

Please help me to connect the oracle database 11g through Laravel 5.7

I spend 4 days still don't make it out just drive me crazy

。My config: Win7-Sp1-64Bit,Xampp-v3.2.2,PHP-7.2.1,Laravel-5.7.1

。I placed the file OCI8-php_oci8-2.1.8-7.2-ts-vc15-x64 (oci8.dll, oci8_11r.dll, oci8_12g.dll) in xampp/php/ext

。I've created Environment Variables in User variables & System variables :

PATH: C:\instantclient_18_3 or C:\instantclient_12_2

TNS_ADMIN: C:\instantclient_18_3 or C:\instantclient_12_2

。Also tried to install：

32bit-instantclient-basic-nt-12.2.0.1.0.zip

32bit-instantclient-basic-nt-12.1.0.2.0.zip

64bit-instantclient-basic-windows.x64-18.3.0.0.0dbru.zip

64bit-instantclient-basic-windows.x64-12.2.0.1.0.zip

OCI8 still can't be loaded in http://localhost/index.php

and I run the command php -m still come out the same result:

Warning: PHP Startup: Unable to load dynamic library 'php_oci8_11g.dll' (tried: C:\xampp\php\ext\php_oci8_11g.dll (%1 is not a valid Win32 application.), C:\xampp\php\ext\php_php_oci8_11g.dll.dll (The specified module could not be found.)) in Unknown on line 0 PHP Warning: PHP Startup: Unable to load dynamic library 'php_oci8_12c.dll' (tried: C:\xampp\php\ext\php_oci8_12c.dll (%1 is not a valid Win32 application.), C:\xampp\php\ext\php_php_oci8_12c.dll.dll (The specified module could not be found.)) in Unknown on line 0
