The golang’s function is a code block like C’s, but it can also be assigned to a variable as its other types.
If you are not familiar with the function, Codewalk: First-Class Functions in Go should be a good starting point for you. Already known it? Let’s go on.
First of all, look at this PHP codes:
function foobar() {
echo "Hello Golang\n";
}
$funcs = array(
"foobar" => "foobar",
"hello" => "foobar",
);
$funcs["foobar"]();
$funcs["hello"]();
It will print:
[email protected]:~/Desktop$ php foobar.php Hello Golang Hello Golang
