Function with different number of arguments

[Mardoxx]

I got the idea when helping here: http://www.phpfreaks.com/forums/index.php/topic,267209.0.html

 

I've created this very sketchy function for pushing string variables into a function:

(hopefully you can see how it works)

<?php
function arg_splitter($input,$arg_count=false,$args_num='args_num') {
$split = preg_replace('/\$|\"/','', preg_split('/\"[\s,]+\$/',$input));
/*  First this splits the inputted string on any number of commas
 *	or spaces inbetween the characters " and $
 *  then it replaces all $ and " characters with nothing
 *	my regex skillz suck.
 */
foreach ($split as $key=>$val) {
	$split[$key] = explode("=",$val);	
	$assocarray[$split[$key][0]] = $split[$key][1]; //creates associative array so you can use extract on it
}
if($arg_count) {
	$assocarray[$args_num]=count($assocarray);
}
return $assocarray;
}


function newfn($inputs) {

extract(arg_splitter($inputs,true,'arg_count')); // Only line needed to be added

if(isset($override) && !is_null($override)) {
	echo "O MAYN, WE GOT OVERRIDDEN!!!!\n<br />";
	echo "\$override = $override\n<br />";
	return;
}
echo "\$a = $a\n<br />";
echo "\$b = $b\n<br />";
echo "\$c = $c\n<br />";
echo "\$d = $d\n<br />";
echo "\$arg_count = $arg_count\n<br /><br />";
}

echo "Test 1: \n<br />";
newfn('$a="apple",$b="banana", $c="carrot",$d="date"');
echo "Test 2: \n<br />";
newfn('$override="apple, banana, carrot, duck"');
?>

 

gives an output of:

 

Test 1:
$a = apple
$b = banana
$c = carrot
$d = date
$arg_count = 4

Test 2:
O MAYN, WE GOT OVERRIDDEN!!!!
$override = apple, banana, carrot, duck 

 

 

Any easier/other way of doing this?

 

 

thanks

Why not just pass the data as an array to begin with, wouldn't that just be easier?

 

function newfn(array $data) {
    foreach($data as $key => $value) {
        // do whatever...
    }
    // whatever here
}

newfn(array('a'=>'apple', 'b'=>'banana', 'c'=>'carrot', 'd'=>'date'));

lol yeah

 

then just a eval("$$key = $value;");

 

(just incase you had newfn(array('a'=>'apple', 'b'=>'array(\'44\'=>\'o hai\')'));

or something )

 

hehe

 

so simple!

 

thanks

Or just do what you did in your other one, instead of eval.... extract

[Mardoxx]

can extract handle arrays and stuff?

[KevinM1]

can extract handle arrays and stuff?

 

What do you think extract() is for?

[trq]

Or....

 

function test() {
  print_r(func_get_args());
}

test(1, 2, 'foo', array(1,5,'blah'), 'what');

[Mardoxx]

no, because then you have to remember what order you entered them in

[Mardoxx]

can extract handle arrays and stuff?

 

What do you think extract() is for?

 

extract(array('a' = > array('a' => 'not this'), 'b' => 'bus'))

 

doesn't work

 

 

//edit fix`d

 

idk why i was evaling...

 

 <?php function newfn(array $data) {
    foreach($data as $key => $value) {
        $$key = $value; //works fine
    }
    // whatever here
} ?>
