function stored inside array

Question

i want to call function store inside array but before i do it i want to check if it is function,string or any other type.

please take a look at my code

$a=new stdClass();
$array = array(function() {
return "Bhavik Patel";
}, "1213",$a);

foreach ($array as $key => $value) {
    if (is_object($value)) {
        echo $value() . "<br/>";
    } else {
        echo $value . "<br/>";
    }
}

by doing this i can check if value is object then i call it but if i pass object it gives (pf course this will give error)

my intention is to find if value is function then call it.

Dear i know how to store function in array. please read carefully what i trying to do — Bhavik Patel

We cannot take that, but don't worry, it won't be closed, and the box you are seeing, is only you who can see, not anyone else — Mr. Alien

To check specifically for anonymous functions you can test the value against \Closure like so:

if ($value instanceof \Closure) {
    echo $value(), "\n";
} else {
    echo $value;
}

The problem with is_callable() is that if your value is "explode", it will return true which is obviously not what you want.

@BhavikPatel Try $value = 'explode'; $value(); and you will see what I mean :)

is_callable() will help you, but notice that if you pass an array like this

array('object or class','method')

is_callable() return true, so you'd better to check it isn't an array

if (is_callable($value) && !is_array($value)) {.....}

see is_callable

A string can also be a callable :)

Try [is_callable][1] in PHP. I have tested it, it works for me.
