EXAMPLES
       Example #1

	      functionname(3) example

	      <?php
	      $serverName = "serverName/sqlexpress";
	      $connectionInfo = array( "Database"=>"dbName", "UID"=>"username", "PWD"=>"password");
	      $conn = sqlsrv_connect( $serverName, $connectionInfo);
	      if( $conn === false ) {
		   die( print_r( sqlsrv_errors(), true));
	      }

	      /* Set up a query to select an invalid column name. */
	      $sql = "SELECT BadColumnName FROM Table_1";

	      /* Execution of the query will fail because of the bad column name. */
	      $stmt = sqlsrv_query( $conn, $sql );
	      if( $stmt === false ) {
		  if( ($errors = sqlsrv_errors() ) != null) {
		      foreach( $errors as $error ) {
			  echo "SQLSTATE: ".$error[ 'SQLSTATE']."<br />";
			  echo "code: ".$error[ 'code']."<br />";
			  echo "message: ".$error[ 'message']."<br />";
		      }
		  }
	      }
	      ?>

NOTES
	By default, warnings generated on a call to any SQLSRV function are treated as errors. This means that if a warning occurs on a call to  a
       SQLSRV  function, the function returns FALSE. However, warnings that correspond to SQLSTATE values 01000, 01001, 01003, and 01S02 are never
       treated as errors. For information about changing this behavior, see sqlsrv_configure(3) and the WarningsReturnAsErrors setting.
