[PHP] A php bug or?..
Hi everyone,
As we all know, count() returns 1 if the variable
is not an array.
Question is: why in the world does it this? If a variable is *notA* an array,
it contains *zero* array elements.
You can answer: but no, man, you can say
$x=world;
$y=$x{3}; // $y=l
so the variable is treated or can be treated as an array.
Well. If strings are treated like arrays, why count($x) doesn't return 5
instead of 1?
Just asking.

I'm assuming it has to do with the value, if not an array or object, being cast
as an array. Thus, non-false equivalent values get cast into an array of size 1:
?php
var_dump((array)1);
var_dump((array)null);
// Output
array(1) {
[0]=
int(1)
}
array(0) {
}

Using count() will return the number of items passed in the first
parameter. If it's an array, each element is an item. If it's a
string, the string is an item. If it's an object, logically, the
items depend on what is contained in the object. However, at no time
does it return the number of characters within a string --- instead,
as you likely know, you'd use strlen().

Hello Daniel, DPB does it return the number of characters within a string --- instead, DPB as you likely know, you'd use strlen(). For sure.

The manual explains what the function does - you may want to check it out cos it does the same for all the other functions too. Returns the number of elements in var. If var is not an array or an object with implemented Countable interface, 1 will be returned. There is one exception, if var is NULL, 0 will be returned. IOW, if you pass it a variable, that has one element, so it returns 1. An array may have 0 to many elements, and null, logically, has none.

No, actually, if it's a string, it's a single item --- thus, 1. The documentation should probably reflect that as well. It wasn't always this way before, though --- in older version of PHP5 it returned 0, and in all versions of PHP4 it did as well. Also, keep in mind that a blank string still constitutes a string and will return 1, but null or nonexistent variables will still return 0. -- /Daniel P.

[PHP] (Apache|php) Bug using modproxy
Hi all,
First time on the list... sorry for any errs.
I am using mod_proxy to pass requests to an internal server in our
lan. The setup looks like
Enduser---INet_link-Mod_proxy_serverLan---PHP_script
Now,
this does not work:
Enduser---https---Apache_mod_proxy-http---Destination_server.
* When a user submits a form (php) with a file upload and $_POST
vars, the $_POST array is mangled (missing) elements and the $_FILES
array is empty
while this works:
Enduser---http---Apache_mod_proxy-http---Destination_server.
* When a user submits a form with a file upload and $_POST vars,
Everything is all good
lmwangi
So something bad? happens when you use https in the request. Anyone
able to reproduce this. Is it a php bug (i doubt it) but you never
know until u waddle through the mod_proxy voodoo.
Here is a sample script
snip
?php
if(isset($_POST['btnSubmit'])){
print_r($_POST);
print_r($_FILES);

Re: [PHP] Re: PHP bug within multi. dimensional arrays?
Matthew Weier O'Phinney wrote:

Hi there,
I am outputting an multidim. array. That works fine, except one thing. The first
letter of the value inside dimension 1 always gets printed.
For example:
I fill the arrays:
while ($row = mysql_fetch_object($result)){
$cat[$row-main_id][name]= $row-main_name;
$cat[$row-main_id][$row-sub_id][name] = $row-sub_name;
}
First off, if you're creating associative arrays, you should quote the
keys:
$cat[$row-main_id]['name'] = $row-main_name;
If you don't do so, PHP assumes you're using a constant value for the
key name.
Then I output them:
foreach ($cat AS $maincat){
echo $maincat[name].':';
Quote your keys!
foreach($maincat AS $subcat){
You do realize that the above will also loop over the index 'name',
right?...
echo $subcat[name].$br;
and since it does, the first element in that array is 'name', which
isn't an array, but a string. Since the 'name' constant isn't defined,
it will interpret that as 'true', or 1, and so it takes the first
character of that string.
I think you'll find the 'name' constant evaluates to FALSE, which in turn
casts to zero, which will give you the first element of the given array,
but as you pointed out its a string not an array so you get the first
char (because php allows array-like access to the individual chars in
a string) ... if it had evaluated to TRUE you would be getting the second
char.
the rest of your explaination is spot on.
}
echo $br;
}
Which does result in:
Europe:E
Germany
UK
North America:N
US
CA
As you can see I get the extra letters N and E. Is this an php error or did I do
something wrong?
So, what you should probably do is create an additional layer in your
multi-dimensional array for the subcategories, and have it of the form
sub_id = sub_name:
$cat[$row-main_id]['subs'][$row-sub_id] = $row-sub_name;
Then loop over that:
foreach ($cat as $main_cat) {
echo $maincat['name'] . :\n;
foreach ($maincat['subs'] as $sub_id = $sub_name) {
echo $sub_name$br; // could also use $sub_id here if
// desired

You should probably do some studying up on multidimensional and/or
nested arrays so you can get a better handle on this stuff.
If you need to be able to add multiple names for a sub_id, do it as an
array:
$cat[$row-main_id]['subs'][$row-sub_id][] = $row-name1;
$cat[$row-main_id]['subs'][$row-sub_id][] = $row-name2;
$cat[$row-main_id]['subs'][$row-sub_id][] = $row-name3;
However, this will break your loop above -- you'll need another layer of
looping added in:
foreach ($cat as $main_cat) {
echo $maincat['name'] . :\n;
foreach ($maincat['subs'] as $sub_id = $names) {
foreach ($names as $name) {

So I thought to myself.. well I should post to bugs.php.net and tell them that I to can reproduce the bug. So I did. Well to make an already long story short.. it looks like after a couple of hours bugs.php.net has removed my post. My question to you is.. is there any reason why they would remove my post? For me.. since I do not write that many lines of code for one run of a script it really didn¹t matter much to me, but since they removed my post.. it's beginning to make me wonder what's going on.. Hopefully someone can shed some light! Well Eugene.. it looks like your post was removed also. We are wondering if it is automatic when a bug is deemed bogus or if there is some other reason.. But then again it takes awhile for it to be removed.. so if it was a script that does it, Im not sure why it would take that long to run.. I really have no clue of what's going on.. and so far only one person on OS X, Mr. Blanchard himself, has not had this problem.. as far as I know. So I don't think they would be ignoring this.. I would be curious to hear what Rasmus had to say.. since I think he would know the innerworkings of php plus the bugs.php.net site.. Anyways hopefully something can be figured out!
