if I show you guys how to do this:
echo sillyFunc()['a'] . PHP_EOL;
using a few brackets and things do you promise not to laugh?
*it's a bit weird*
id like to see it.

don't say I didn't warn ya fellow nathan!
#!/usr/bin/php
<?php
function sillyFunc() {
return array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e'=>'some string');
}
echo !${~${''}='sillyFunc'}=&${''}().${~${''}}['e'] . PHP_EOL;
--- output ---
some string
To make things a little weirder yet here's the var's lol:
print_r(get_defined_vars());
[] => sillyFunc
[¹] => Array
(
[a] => 1
[b] => 2
[c] => 3
[d] => 4
[e] => some string
)
to reference the var holding "string sillyFunc" (any of):
echo ${''}; echo ${NULL}; echo ${FALSE};
to reference our array [¹] (yeah it is called ¹)
print_r(${~${''}});
here's a quick simplification + alternatives.
echo (!$array = sillyFunc()),$array['e'];
echo (!$array = sillyFunc()).$array['e'];
and a useful ternary one:
echo is_array($array = sillyFunc()) ? $array['e'] : '';
told you it was a bit weird [took me a couple hours to figure out]!
