If you are using a higher loglevel, you'll get a notice for a not existing array
key.
In the othercase
$array[$mykey] += 1;
will work without notice. But as the key does not exist, the value will be null
and right now I am not sure what
null + 1
evaluates to?
Well, works....
maro@marco-behnke:~$ php -a
Interactive shell
php > $array = array();
php > $array['foo'] += 1;
PHP Notice: Undefined index: foo in php shell code on line 1
PHP Stack trace:
PHP 1. {main}() php shell code:0
php > var_dump($array);
array(1) {
["foo"]=>
int(1)
}
BUT I stronly recommend not to do that.
make it this way:
$array[$mykey] = array_key_exists($mykey, $array) ? $array[$mykey] += 1 :
$array[$mykey] = 1;
or better:
if (array_key_exists($mykey, $array)) {
$array[$mykey] += 1;
} else {
$array[$mykey] = 1;
}
