When indexing a string, the string is cast to an integer:
(int)'file' == 0
When in a conditional expression, the string is cast to a boolean:
(bool)'file' == true
It isn't necessarily a fatal error, consider:
$keys[ '3' ]

Can someone explain the following to me?
echo "DEBUG:\n";

var_dump($keys['file']);
var_dump(isset($keys['NOTEXISTING']));
var_dump(isset($keys['file']));
exit;
DEBUG:
string(19) "myConsoleController"
string(1) "m"
bool(true)
bool(true)
Now, it seems that $keys['file'] == $keys[0], which makes sense why
the issets
return true. However...
if ('file') echo 'true';
will print moo, therefore 'file' == 1, not 0. Why is this different
when using
it as a string offset?
IMO, using a string as a string offset, a fatal error should be
raised.
