How to execute a SELECT statement of the Orcal database in PHP and get the total number of rows and values of a column

How do I use PHP to execute a SELECT statement of the Orcal database and get the total number of rows and values of a column?
That's it:
$query = "Select Id,bt,fbsj from TZTG";
Here is the execution statement;
$rows = number of rows fetched;

for ($i =0; $i < $rows; $i + +)
{
The value of the first column is obtained here;


Somebody help me, hurry!
