PHP Gurus Please Come In: Variable Function Definition?

[Gias Kay]

Hi gurus lol

I have three function definitions here:


function int_register() {
$num_args = func_num_args();
for ($i = 0; $i < $num_args; $i ++) {
$parameter = func_get_arg($i);
if (isset($_REQUEST[$parameter])) {
global $$parameter;
$$parameter = intval($_REQUEST[$parameter]);
}
}
}

function string_register() {
$num_args = func_num_args();
for ($i = 0; $i < $num_args; $i ++) {
$parameter = func_get_arg($i);
if (isset($_REQUEST[$parameter])) {
global $$parameter;
$$parameter = trim(escape_string(htmlentities($_REQUEST[$parameter])));
}
}
}

function array_register() {
$num_args = func_num_args();
for ($i = 0; $i < $num_args; $i ++) {
$array = func_get_arg($i);
if (isset($_REQUEST[$array])) {
$process = "";
foreach ($_REQUEST[$array] as $rip) {
$process[] = trim(escape_string(htmlentities($rip)));
}
global $$array;
$$array = array();
foreach ($process as $parameter) {
array_push($$array, $parameter);
}
}
}
}

As you can see, there are lots of similar parts inside the definitions of these three functions; as such I am trying to find a way to compress them into one code bloc.

I've tried the variable function concept but it didn't work:


$lolz = array('int_register', 'string_register', 'array_register');
foreach ($lolz as $lol) {
function $lol() {
[DEFINITIONS]
}
}

I know it would be way lot easier if I redo the functions into something like:

function register($flag) {
switch ($flag) {
case "int":
[DEFINITION]
}
}
But I regard this as a last resort and would not do so if there are other solutions. So... is there really any other solution?
