Bug Type: Arrays related
Operating System: Red Hat Linux 7.2
PHP Version: 4.2.2
New Comment:
I agree that it would be a great thing if foreach() could manage empty
or uninitialized arrays without throwing any error...
Because in my script I have to replace each occurence of this:
foreach ($a as $val) {
...
}
with :
if (is_array($a)) {
foreach ($a as $val) {
...
}
}
which is quite a hassle to do.
Take a look at the following example:
$a = '';
while ($a) {
//...
}
foreach ($a AS $val) {
//...
}
Why doesn't the "while" throw an error if the "foreach" does???
I guess it wouldn't be much to change in PHP source code???

Super! Thanks.
Is there any chance that in the future foreach will be able to handle
null arrays. I'm used to foreach in perl and if I remember correctly it
doesn't mind unitialized arrays. But I might be wrong ...
Anyway, I'm more than happy with a clarification in the docs.

FYI: I clearified this in the manual, it will show up in a few days
online.

Neglectful coding? Why do you consider it neglectful coding if I do
this for an array but good coding for a string? PHP treats null strings
as empty strings, why doesn't it do the same for arrays?
All I want to know is, what is the documented behaviour for foreach on
a null array. If there is no documented behaviour, let's add to the
documentation. Something like:
"foreach will fail on an unitialized (null) array".
I had assumed that since PHP is usually treats null strings as empty
strings it would do the same with null arrays. I was wrong. I tried to
find documentation on what foreach will do in the case of a null array
and could not find any.
I agree with you that this is neglectfull coding. It would be nice if
there was documentation to back it up :)
