#28435 [Com]: array_count_values() problem
ID: 28435
Comment by: php_bugs at michaeldouma dot com

Bug Type: Arrays related
Operating System: Any
PHP Version: 4CVS-2004-05-18 (stable)
New Comment:
Why is this bug closed? I am now experiencing the same
problem with 5.0.1. The array from array_count_values
appears normal with vardump, but there is no way to
access the elements; neither as arrayname[2] nor
arrayname[2]. This worked fine with 4.3.x.
vardump of result from array_count_values
array(5) {
[3]=
int(2)
[2]=
int(1)
[1]=
int(1)
[0]=
int(1)
[0]=
int(0)
}
It looks like you'd be able to access the value with
arrayname[2], but you can't!

As said in :
- bug #9307
- bug #21918
- bug #22201
- and documentation of arrays :
http://www.php.net/manual/en/language.types.array.php
If a key is the standard representation of an integer, it will be
interpreted as such (i.e. 8 will be interpreted as 8, while 08 will
be interpreted as 08).
So the array_count_values must cast the integers contained in strings
to integers.
Actually, with standard PHP behavior, it's impossible to access
directly to those array elements which keys are strings containing
integers, as said in comment of June 18

Ok, I think you're right, we all should be looking forward working with
php5, rather than trying to fix old bugs in php4.

The php5 result seems more accurate than the php4 one. You got strings
in the $books array, no?
Changing this in php4 may break some code out there so maybe it'd be
best to just mention it as a 4-5 inconsistency.

I noticed this problem with PHP5 RC2 on a Win2k box as an
Apache2-module. I have some HMTL-Checkboxes and on the server side want
to check the selected values. My checkboxes are equally named
name=choice2[] what lets PHP generate an array
$_POST[choice2][0]
$_POST[choice2][1]
$_POST[choice2][2] etc. according to the selected values.
Each checkbox has it's unique value attribute.
To test for a certain value I reverse this array with
$arrTmp=array_count_values($_POST[choice2]);
I now want to access $arrTmp[1] to check if the checkbox with the
attribute value=1 was selected. The respective value was - if
selected - 1, otherwise it's not existent in the
$_POST[choice2]-Array. This did not work. $arrTmp[1] didn't work
either. It was no way possible to access a member of the array.
The other poster mentioned the indexes are generated as strings, I want
to point they cannot be accessed at all.
It worked best on PHP 4.3.6
Best,
Bernhard

Description:
I don't know if this is a php5 or php4 bug, but I'm sure something's
wrong here.
Whenever in php5 I do an array_count_values() on an array that
contains numeric values as strings the result array uses string keys
instead of the numeric values as indexes. This doesn't happen in php4.
I don't know what behaivor is correct.
I'm using the latest cvs versions of both php4 and php5 btw.
Reproduce code:
---
?php
$books = Array('10', '3', '6', '10');
$quantities = array_count_values($books);
var_dump($books);
var_dump($quantities);
?
Expected result:
This is what happens in php4:
array(4) {
[0]=
string(2) 10
[1]=
string(1) 3
[2]=
string(1) 6
[3]=
string(2) 10
}
array(3) {
[10]=
int(2)
[3]=
int(1)
[6]=
int(1)
}
Actual result:
--
This is what happens if php5:
array(4) {
[0]=
string(2) 10
[1]=
string(1) 3
[2]=
string(1) 6
[3]=
string(2) 10
}
array(3) {
[10]=
int(2)
[3]=
int(1)
[6]=
int(1)
}
