<?php

// open in read-only mode
$db = dbase_open('/tmp/test.dbf', 0);

if ($db) {
  $record_numbers = dbase_numrecords($db);
  for ($i = 1; $i <= $record_numbers; $i++) {
      // do something here, for each record
  }
}

?>

Trying to get number of records in 1 of my "MySQL" tables. My database has 3 tables in it. How does it know which table to count records in.

Spent an hour and a half looking through Google links to dbase_numrecords, every place I go has a mirror image of the same example, but does not specify which table.

I understand, $db is the string that holds the name of the database. Or should it be the name of the table in the database.
