Question

I just want to make a function like array_merge ( array $array1 [, array $... ] )
or simple function like myfunc($st1, $st2, $st3, $st4, $st5, etc)

function make_my_merge($) {
     ..... operation to be performed ......
}

Answer 1

Use func_get_args() to access all arguments (as an array) passed to the function. Additionally, you can use func_num_args() to get a count of all arguments passed in.

function make_my_merge () {
    if ( func_num_args() ) {
        $args = func_get_args();
        echo join( ", ", $args );
    }
}

// Foo, Bar
make_my_merge("Foo", "Bar");

// Foo, Bar, Fizz, Buzz
make_my_merge("Foo", "Bar", "Fizz", "Buzz");
