#33879 [NEW]: $string["otherstring"] = something | should produce a warning
From: sigge at hystrix dot se
Operating system:
PHP version: 5.0.4
PHP Bug Type: Strings related
Bug description: $string["otherstring"] = something | should produce a warning
Description:
------------
I recently had a bug in my code that overwrote an array with a string. I
missed the [], it happens.
But debugging was hard, and I had a bunch of $array["foo"] = "bar"; when
$array had been overwritten by a string.
As kind people on #php explained to me, PHP treats any string as 0. While
I can understand such behaviour, I think there should be a warning like
"you are treating a string as an array" or something.
This warning should probably not occur when the key is a number, as this
would return the character, but when accessing a string key of a string
makes no sense.
I can't see how this would break any backward compatibility, and it would
make debugging much easier!
Edit: I've now seen that there are similar bugs, all marked closed and
without any non-stock explanation.
I would really like to know why this "is expected", because to me, having
developed in PHP for two years, this wasn't expected at all, and caused me
a good headache.
Pardon me if I am spamming, I would prefer to add a comment to those bugs,
but can't.
Reproduce code:
---------------
$array = array();
$array = "string";
$array["foo"] = "bar";
Expected result:
----------------
Would be nice if it produced a warning on line 3, "Trying to access a
string as an array"
