How can multiple instances of $xtplx->out("main") in different template files be managed effectively in PHP applications using xtemplate?

When using xtemplate in PHP applications, managing multiple instances of $xtplx->out("main") in different template files can be achieved by using unique identifiers or variables to distinguish between the different instances. This can be done by passing a parameter to the out() function to specify which instance should be output at a given time.

// Example of managing multiple instances of $xtplx->out("main") in different template files

// In template file 1
$xtplx->out("main", "template1");

// In template file 2
$xtplx->out("main", "template2");

// In main PHP file
if ($xtpl->out == "template1") {
    // Output content for template 1
} elseif ($xtpl->out == "template2") {
    // Output content for template 2
}
