PHP到MS-SQL Server

Question

I am attempting to get a site using PHP to connect to my Microsoft SQL Server, below is everything I can think of:

Server : 2012
SQL Server : 2012
PHP : 7.2.6
Code :

<?php 
$serverName = "ServerName";
$connectionInfo = array( "Database"=>"DBname", "UID"=>"user.name", "PWD"=>"K5zUtwDdzyX8T1vmvtEL");
$conn = sqlsrv_connect( $serverName, $connectionInfo);
if( $conn==true ) {
    echo "Connection established.<br />";
}else{
    echo "Connection could not be established.<br />";
    die( print_r( sqlsrv_errors(), true));
}
?>

Other :

• The Site and SQL Server are on different machines
• Both boxes are Windows
• PHP was installed manually not through IIS
• Only error I receive is "500 Internal Server Error"
• I have installed the drivers from Microsoft

If there is anything I have left out please let me know and I will promptly provide it. I have been lost for quite some time, I am open to any suggestions.

Thank You, I enabled the error display using your link which then displayed the error:

Fatal error: Call to undefined function sqlsrv_connect()

Which led me to this post: Fatal error: Call to undefined function sqlsrv_connect() so adding the below to my ini file resolved that issue.

extension = php_sqlsrv_72_nts_x64.dll
