Could someone explain to me the difference between using => or ->? Is there any logical difference? Thanks!

If you can add into your question the case where you thought the two symbols might be interchangeable, that might make for a unique question. I should be interested to that code in any case. – halfer Jan 19 '14 at 19:49

=> is used when defining arrays, and also in foreach loops that use keys, e.g.
$foo = array('bar' => 'baz');
foreach ($array as $key => $value) {...}
-> is used to refer to object members, e.g.
$obj->method();
$obj->property;
They are never interchangeable.

@AbhiBeckert added `foreach` example. AFAIK they are the only two uses... – George Brighton Jan 19 '14 at 19:15

@DamienPirsy checke the language specification, I'm aware of at least 4 of them, but there are probably more. – Abhi Beckert Jan 19 '14 at 19:39

@Abhi, I should be interested too what the other uses are - you've got me curious! – halfer Jan 19 '14 at 19:47

@AbhiBeckert Nope, I'm trying but can't find the other 2 uses (besides arrays and foreach) you're talking about. Please stop being mysterious and tell us! :) – Damien Pirsy Jan 19 '14 at 19:51
