Well, although it is strongly not recommended to disable Include common files option for Custom File if you want to get data from database into a Custom File, however, as matter of fact, PHPMaker v2025 has still the ability to allow us to disable that option, after I reading this following post: What is the equiv. of loading system libraries? - #7 by yaaryvp
So, if you want to obviously to disable that option (again, it is strongly not recommended), here is the code to get data from database into a Custom File with disabling the Include common files option for v2025:
<?php
namespace PHPMaker2025\demo2025;
use DI\ContainerBuilder;
// Autoload
require_once "vendor/autoload.php";
// Require files
require_once "src/constants.php";
require_once "src/config.php";
require_once "src/phpfn.php";
require_once "src/userfn.php";
$containerBuilder = new ContainerBuilder();
$containerBuilder->useAttributes(true);
// Add definitions
$containerBuilder->addDefinitions("src/definitions.php");
// Dispatch container build event
DispatchEvent(new ContainerBuildEvent($containerBuilder), ContainerBuildEvent::NAME);
// Build PHP-DI container instance
$container = $containerBuilder->build();
echo "<h3>Custom File without Include common files option</h3>";
$sql = "SELECT `Model` FROM `models`"; // define your SQL
$stmt = ExecuteQuery($sql); // execute the query
$value = ""; // initial value
if ($stmt->rowCount() > 0) { // check condition: if record count is greater than 0
while ($row = $stmt->fetchAssociative()) { // loop
$value .= $row["Model"] . "<br>"; // in case the result returns more than one record, display it and separated by line break
} // end loop
echo "Here is the Models list: <br>" . $value; // display the result
} else { // if there are no result
echo "No record found."; // display the message
} // end of check condition
?>
