Description:
------------
The anonymous functions wouldn't really be complete without dereferencing, making
it easier for developers to split their code up into chunks, and having one return
value. Database calls that are only going to be called once for example, but need
to be stored in an array. There's no point making a whole function for it and no
point setting it to a variable to be run once.
Test script:
---------------
$my_array = [
'key_1' => function() {
return mt_rand();
}(),
'database' => function() {
$db = new PDO("mysql:host=127.0.0.1; port=3306;", "root",
"");
$sth = $db->prepare("SELECT * FROM users WHERE username=?
LIMIT 1");
$sth->bindParam(1, 'Test');
$sth->execute();
return $sth->fetch(PDO::FETCH_ASSOC);
}()
];
Expected result:
----------------
An array with two values, a random value on 'key_1' and an associative array on
'database'.
Actual result:
--------------
Parse error: syntax error, unexpected '(', expecting ']' in php shell code on
line
4
When leaving out the parentheses; two closure classes.
