count array in PHP giving unexpected output

I have 2 following data:

$temp = Array
(
    [@url] => url
    [@type] => image/jpeg
    [@expression] => full
    [@width] => 644
    [@height] => 429
)

$count_total = count($temp); // gives me 5, how can it give me total = 1?

Array
(
    [0] => Array
        (
            [@url] => url1
            [@type] => image/jpeg
            [@expression] => full
            [@width] => 800
            [@height] => 621
        )

    [1] => Array
        (
            [@url] => url2
            [@type] => application/x-shockwave-flash
        )

)
this is total:2 // this is correct

How can I get first array count as 1?

It is counting the amount of elements in the array. The first is giving you 5 because the array has 5 elements. The second is giving you 2 because it is a multi-array containting 2 elements (arrays).

To make it return one you can put the array inside of an array, so like this:

Array([0] => Array())

I hope this answered your question.

$temp = Array 
       (
       [0] => Array
              (
                   [@url] => url
                   [@type] => image/jpeg
                   [@expression] => full
                   [@width] => 644
                   [@height] => 429
               )
       );

$count_total = count($temp); //gives you 1

Problem is that in your first block of code you are trying to count number of elements of array which in second block is insido of another array.

If you got single result, you do the following:

$temp = Array
(
    [@url] => url
    [@type] => image/jpeg
    [@expression] => full
    [@width] => 644
    [@height] => 429
);

Single result:

$new_temp[0] = $temp;

Now you get:

count($new_temp); // get 1

This will give you the count 1

$temp[] = Array
(
    [@url] => url
    [@type] => image/jpeg
    [@expression] => full
    [@width] => 644
    [@height] => 429
)

$count_total = count($temp);

     $temp = Array
     (
         [0] => Array
             (
            [@url] => url1
            [@type] => image/jpeg
            [@expression] => full
            [@width] => 800
            [@height] => 621
        )
)

 $count_total = count($temp);

if your array is above, you can get count as 1;

The array below(given by you)

$temp = Array
(
[@url] => url
[@type] => image/jpeg
[@expression] => full
[@width] => 644
[@height] => 429
)

have 5 values with indexes @url, @type, @expression, @width, @height. So it always will give you the count 5.

If you want to get count 1. You have to do like below

$temp = Array(
    array(
        [@url] => url
        [@type] => image/jpeg
        [@expression] => full
        [@width] => 644
        [@height] => 429
    )
);

Here count($temp) will give you output 1
