Problem inserting parameters into a function

Question

Ok, I am trying to place parameters into a function that is called like so:

$parameters['function']($parameters['params']);

Here is the function and the parameters that I need to be placed into this:

$parameters['function'] = 'test_error';
$parameters['params'] = array(0 => $txt['sometext'], 1 => 'critical', 2 => true);

The test_error function takes 3 parameters:

1. The error to output
2. The type of error noted within a string value ('general', 'critical', etc. etc.).
3. Whether it should be echoed or not.

Here is the output I get: Here is a test error.ArraycriticalArray1

I know this function works perfect, but it only gives me the 1st parameter returned from it. What am I doing wrong here with the $parameters['params']??

EDIT: Here is the function:

function test_error($type = 'error', $error_type = 'general', $echo = true)
{
    global $txt;

    // Build an array of all possible types.
    $valid_types = array(
        'not_installed' => $type == 'not_installed' ? 1 : 0,
        'not_allowed' => $type == 'not_allowed' ? 1 : 0,
        'no_language' => $type == 'no_language' ? 1 : 0,
        'query_error' => $type == 'query_error' ? 1 : 0,
        'empty' => $type == 'empty' ? 1 : 0,
        'error' => $type == 'error' ? 1 : 0,
    );

    $error_html = $error_type == 'critical' ? array('<p class="error">', '</p>') : array('', '');
    $error_string = !empty($valid_types[$type]) ? $txt['dp_module_' . $type] : $type;

    // Should it be echoed?
    if ($echo)
        echo implode($error_string, $error_html);

    // Don't need this anymore!
    unset($valid_types);
}

Answer 1

You probably want call_user_func_array(). Each item of the array passed as the 2nd argument will be used as a function argument, for example:

call_user_func_array( $parameters['function'], $parameters['params'] );

Answer 2

See below.

http://www.php.net/manual/en/function.call-user-func-array.php

<?php
function foobar($arg, $arg2) {
    echo __FUNCTION__, " got $arg and $arg2\n";
}
class foo {
    function bar($arg, $arg2) {
        echo __METHOD__, " got $arg and $arg2\n";
    }
}


// Call the foobar() function with 2 arguments
call_user_func_array("foobar", array("one", "two"));

// Call the $foo->bar() method with 2 arguments
$foo = new foo;
call_user_func_array(array($foo, "bar"), array("three", "four"));
?>
