Question

I have a problem, I have this result below and I want to remove the same timestamp.

Sample Result:

Array
(
[0] => [1341100800000, 0]
[1] => [1341100800000,85]
[2] => [1343779200000,54]
[3] => [1343779200000, 0]
)

Expecting Output

Array
(
[0] => [1341100800000,85]
[1] => [1343779200000,54]
)

I’m thinking of using explode then substr function to get the value. Here is what I came up so far..

$explode = array();
    foreach($string_format as $key => $value) {
        $explode[] = explode(',', substr($value, 1));
        if((isset($explode[0]) && $explode[0][0] == $explode[1][0])) {
            unset($explode[0]);
        }
        //print_r($explode);

    }
