How to execute a custom function from the function itself?

Question

PHP

How to call a function in PHP header and pass parameters to it?
For example:myFunc('helloworld',function(){ echo "test" });

Answer 1

We check whether the variable is a value or a function, if it is a function, then we call it

myFunc('helloworld', function(){ 
    echo "test" 
});

function myFunc($key, $object){
    return is_callable($object) ? call_user_func($object):$object;
}

Answer 2

For example like this:

function myFunc($text, $func)
{
    $func($text);
}

myFunc("blabla", function($param) { echo $param;});

Answer 3

$hello = function($name = '') {
    return "Hello $name";
};
echo $hello('John'); // Hello John
