php weird json result array

I'm returning a json result out of a pdo query like this:
json_encode($query->fetchAll(PDO::FETCH_ASSOC));

And when i receive i do it like this:
$array	= json_decode($output,true);
print_r($array);

Open in new window

and gives me this:
Array
(
    [0] => Array
        (
            [packstamp] => pmarketing
        )

    [1] => Array
        (
            [packstamp] => peventos
        )

    [2] => Array
        (
            [packstamp] => psystem
        )

    [3] => Array
        (
            [packstamp] => ploja
        )

    [4] => Array
        (
            [packstamp] => pproject
        )

)

Open in new window

And the json string is this:
[{"packstamp":"pmarketing"},{"packstamp":"peventos"},{"packstamp":"psystem"},{"packstamp":"ploja"},{"packstamp":"pproject"}]

Open in new window

i can't parse this right....
I try to get the value of each packstamp like this:
foreach($array as $row) {
	echo trim($row['packstamp']);
}

Open in new window

And the result is always the same, the value of the first column "pmarketing,pmarketing,etc..." instead of "pmarketing,peventos,etc..."

I thought the foreach would the same as i do with the parse of the pdo array result, but i guess not...

Can someone help me?

Thx in advanced,
Miguel

correction... i was doing a return during my foreach in my production code..
it gives all results, the only problem is that repeats the results 5 times...
like this
pmarketing
peventos
psystem
ploja
pproject
pmarketing
peventos
psystem
ploja
pproject
pmarketing
peventos
psystem
ploja
pproject
pmarketing
peventos
psystem
ploja
pproject
pmarketing
peventos
psystem
ploja
pproject

Try this:

foreach ($array as $row) {
	print $row['packstamp'] . "\n";	
}

I am confused how you got that output without "\n".  

Regarding repeating results, did you put a foreach inside a foreach?  Can you give a little more code?  

I'm testing with this and it works fine for me.  

<?php
$array = json_decode('[{"packstamp":"pmarketing"},{"packstamp":"peventos"},{"packstamp":"psystem"},{"packstamp":"ploja"},{"packstamp":"pproject"}]', true);

foreach($array as $row) {
	echo trim($row['packstamp']);
}

This is a compound statement:

json_encode($query->fetchAll(PDO::FETCH_ASSOC));

Open in new window

Compound statements are PHP AntiPractice #9.  Don't write code like that - it's a sure signal that a programmer is not very experienced, and it's very hard to debug.   Instead, write one line of code on each line of the program script.  You probably want something like this so you can visualize the data that is returned from the PDOStatement object.

while ($row = $query->fetchAll(PDO::FETCH_OBJ))
{
    // ROW BY ROW PROCESSING IS DONE HERE
    foreach ($row as $key => $obj)
    {
        echo "$key: ";
        print_r($obj);
        echo PHP_EOL;
    }
}

Open in new window

Once you see the return data you will immediately have a better idea how to use it with JSON_Encode().   If you can make those changes and show us the output of the foreach() loop, then we can move right on to getting the JSON string right.

Ray,

Sorry for not telling the all story.
I don't use the "PDO::FETCH_ASSOC", in fact i don't use it at all.
I do like this:
$pdo->prepare($sql, array(PDO::ATTR_CURSOR => PDO::CURSOR_FWDONLY));
$query->execute();
and
$query->fetchAll();
And as always worked fine for me.
But since with json_encode was giving me this kind of array, i tried with "PDO::FETCH_ASSOC" (i saw it in stackoverflow). I'm only using this with json results.

I'm gonna try as you say.
