You can't call functions inside {} directly like this, but you can use variables-holding-the-function-name and call those!

You can't call functions inside {} directly like this, but you can use variables-holding-the-function-name and call those! (*and* you can use variable variables on it, too)

Found this little gem in Reddit comments:

$foo = 'abcde';
$strlen = 'strlen';
echo "$foo is {$strlen($foo)} characters long."; // "abcde is 5 characters long."

So, just discovered you can pass any string as a method name IF you enclose it with curly brackets. You can't define any string as a method alas, but you can catch them with __call(), and process them further as needed. Hmmm....

class foo {
  function __call($func, $args) {
    eval ($func);
  }
}

$x = new foo;
$x->{'foreach(range(1, 10) as $i) {echo $i."\n";}'}();
