Removing row from array based on duplicate value of a key

Question

I have a array called $data['job_list'] which is as follows

[job_id] => 2 is present twice

What I want is that, the row with duplicate job_id => 2 should be removed

How can I achieve that??

I havent tested, but I think array_unique would do the job for you: php.net/manual/en/function.array-unique.php — bestprogrammerintheworld

$jobIds = array();

foreach ($jobs as $key => $job) {
    if (in_array($jobIds, $job['job_id'])) {
        unset($jobs[$key]);
        continue;
    }
    $jobIds[] = $job['job_id'];
}

print_r($jobs);

I would cycle though each "job" and create an array of Job IDs. If I see the same ID twice then I would remove the duplicate and store it somewhere else if needed.

As Matei Mihai stated, i made some minor changes in his script and bingo it solved..

Matei Mihai made a mistake regarding the data-type of arguments of the in_array() function

I fixed that.

here's my code

    $jobIds = array();

    for($i = 0;$i < count($data['job_list']); $i++ )
    {
        if (in_array($data['job_list'][$i]['job_id'], $jobIds))
            {
                unset($data['job_list'][$i]);
                continue;
            }
        $jobIds[] = $data['job_list'][$i]['job_id'];
    }
