Why PHP can't use Sqlsrv_connect with cmd - php

Question

I make sure that I can run website with WampServer,and also can connect the Sql Server.However,I run the bat file by the operating system scheduler,that return error:
OK,Can Run PHP
Fatal error: Uncaught Error:Call to undefined function sqlsrv_connect() in C:\wamp64\www\shell.php
Stack trace:
#0{main}
thrown in C:\wamp64\www\shell.php
My configuration : WampServer 3.0.6 64bits (PHP 7.0.10, Apache 2.4.23)
There are my steps:
First: I wrote a bat file in \wamp64\bin\php\php7.0.10
C:\wamp64\bin\php\php7.0.10\php.exe -q C:\test.php
PAUSE
Second: The function sql_connect is basic on php
echo "OK,Can Run PHP";
$serverName = "------";
$uid = "------";
$pwd = "------";
$connectionInfo = array("UID"=>$uid, "PWD"=>$pwd, "Database"=>"------","characterset"=>"utf-8");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn == false){
echo "Error<br>";
die( print_r( sqlsrv_errors(), true));
}
else{
echo "OK<br>";
}
Third: Put the bat in the operating system scheduler(Win7 64bit)
The cmd also can work by php -v and php -f.I think that cmd can work PHP with bat on the operating system scheduler because it answer "OK,Can Run PHP".
And then,the problem maybe is in "sqlsrv_connect()".
However,I really don't know that why the function "sqlsrv_connect()" can work in localhost website but can't work cmd without website. Please help me!!
