Cant get last array value

Question

I dont understand why my array gets cut in loop?

Array
(
    [0] => Array
        (
            [name] => order
            [value] => asd
        )

    [1] => Array
        (
            [name] => item
            [value] => aa
        )

    [2] => Array
        (
            [name] => quant
            [value] => 5
        )

    [3] => Array
        (
            [name] => price
            [value] => 20
        )

)

My php code with for loop:

for($i = 0; $i < count($json_array); $i++)
{
    echo $json_array[$i]['name'];
}

The result I'm getting is: orderitemquant but why last value price is gone? What is wrong with this code?

Are you sure $json_array is what you think it is? try printing out the array values first to make sure print_r($json_array); — JConstantine

I get orderitemquantprice so you are misrepresenting something. There should be no spaces in your output for instance. Are you leaving out the logic that creates the space? — Esailija

I give up, if this is the complete code, I have no idea how this can be happening — Draiken

Have you tried using foreach? In my opinion it suits better for iterating your array.

foreach($json_array as $sub_array) {
    echo $sub_array['name'];
}

Try this, off by one error:

for($i = 0; $i =< count($json_array); $i++)
{
    echo $json_array[$i]['name'];
}

Another answer with the same suggestion got too many negative votes and was deleted. There is no mistake in writing like the author of the question has written. It really depends on situation and there is no reason to add = sign to comparison as we are counting from zero to three. Your code counts from zero to four, which is definitely incorrect and will result in an error as $json_array[5]['name'] does not exist. Your answer is only correct if you want to count from one.

Okay sorry, you're right. I'll let it be existing here so this won't be repeated!
