Example for named function with parameters

[gnanet]

Looked at the examples, and reading the php docs about call_user_func_array i was missing the example, how it can be used with a pre-defined function, including parameters.

I would suggest a rather extensive example:

// Define function that handling routes, and has a default value for the variable
function my_func($my_var = 'default value') {
  return 'This is a working pre-defined function. Parameter: '.$my_var;
}

// Add your index route
Route::add('/', function() {
  return my_func();
});

// Add your first route
Route::add('/browse/(.*)', function($var) {
  return my_func($var);
});

Sorry for this late answer. Holidays.

Try to use func_get_args() inside your predefined function. So you can have a variable number of arguments: https://www.php.net/manual/en/function.func-get-args.php

Not tested code:

function my_func() {
  // Get all the function args without defining them inside the function head
  $arg_list = func_get_args();

  // Print all function args
  print_r($arg_list);
  
  // Return your content
  if(count($arg_list)){
    return 'This is a working pre-defined function. Parameter: '.$arg_list[0];
  } else {
   return 'This is a working pre-defined function. Parameter: Nor args given';
  }
  
}

Route::add('/', 'my_func');

Route::add('/browse/(.*)', 'my_func');
