Altering an array

[spenceddd]

Hello,

 

I am just trying to work out how replace the contents of the following array:

 

Array

(

    [0] => Array

        (

        )

 

    [1] => Array

        (

            [0] => 18

            [1] => 7

            [2] => 5

            [3] => 4

        )

 

    [2] => Array

        (

            [0] => 48

            [1] => 7

        )

 

    [3] => Array

        (

            [0] => 7

            [1] => 5

            [2] => 4

        )

 

    [4] => Array

        (

            [0] => 48

            [1] => 18

            [2] => 7

            [3] => 5

            [4] => 4

        )

 

)

 

With a new array which replaces the sub array items with one item that is equal to the count of each sub array.. does that make sense? so the resulting array in this case would look like:

 

Array

(

    [0] => Array

        (

 

        )

 

    [1] => Array

        (

            [0] => 4

        )

 

    [2] => Array

        (

            [0] => 2

        )

 

    [3] => Array

        (

            [0] => 3

        )

 

    [4] => Array

        (

            [0] => 5

       

        )

 

)

does that make sense?

 

Not in particularly. Your formatting doesn't really help either.

Your array is a bit messy looking but...

see if this gives you what you expect

 

$new_array=array();
$i=0;
foreach($array as $sub)
{
   $num=count($sub);
$new_array[$i]=$num;
$i++;
}

Sorry for the nonsensicalness. I was rushing earlier.

 

Here goes again:

 

I have an array which contains a subset of arrays:

Array(    
    [0]=> Array(
                                         )
    [103] => Array(           
                          [0]=> 18
                          [1] => 7
                          [2] => 5
                          [3] => 4
                                         )
    [112] => Array (
                          [0] => 48
                          [1] => 7
                                         )
    [123] => Array (
                          [0] => 7
                          [1] => 5
                          [2] => 4
                                       )
    [140] => Array (
                          [0]=> 48
                          [1] => 18
                          [2] => 7
                          [3] => 5
                          [4] => 4
                                        )
)

What I am trying to is create another array which is derived from this. The subset arrays of the new array would contain just one entry which reflects the count of the original arrays subset counterpart. So the new array would look like this:

Array(    
    [100]=> Array(
                                         )
    [103] => Array(           
                          [0]=> 4
                                       )
    [112] => Array (
                          [0] => 2
                                       )
    [123] => Array (
                          [0] => 3
                                       )
    [140] => Array (
                          [0]=> 5
                                       )
)

Thanks for the reply teamatomic, I am just working through your suggestion now.

If your first array is called $a.

 

$new = array();
foreach ($a as $k => $v) {
  $new[$k] = array(count($v));
}

[sasa]

or

foreach ($a as $k => $v) {
  $a[$k][] = count($v);
}

[trq]

or

foreach ($a as $k => $v) {
  $a[$k][] = count($v);
}

 

All that does is add a new element to each inner array containing the count before it was added.
