array_search

[ligraci]

Hi to all!
I'm using for the first time the function array_search and I'd like to understand the error it gives to me. This is the code:

$array=array(1, 2, 3, 4);

function foo ($a, $b, $c, $d) {
$key1 = array_search($a, $array);
$key2 = array_search($b, $array);
echo $key1." ".$key2;
}

foo ($e, $f, $g, $h);

And this is the error:
Warning: Wrong datatype for second argument in call to array_search in URL on line n

Any idea?

Thanks a lot ^_

$array inside the function is a local variable, and is not the same as your pre-defined $array outside the function.

what you can do is, inside the function have this line:

function foo(...) {
global $array;
...
}

or you can have a fourth parameter in function arguments, to pass the array through that.

this should fix the problem.
