Remove elements in a row of an array [duplicate]

Question

I'm developing an API which produces results in JSON format, when I encoded results into JSON using PHP, it shows every element in the row of the array. I use MySQL to grab data.

foreach($search as $item) {
    echo json_encode($item);
}

This will output

{"id":"1","name":"A","tag":"a A","url":"A"} {"id":"2","name":"B","tag":"b B","url":"B"}

Is there a way to dump TAG element so it won't appear in JSON encoded results?

Wouldn't it be easier only selecting the columns in your SQL SELECT statement that are needed for the JSON output? — dbf

foreach($search as $item) {
    unset($item['tag']);
    echo json_encode($item);
}

you can do it by unset()

You can remove the element from the array before json_encode

foreach($search as $item) {
    unset($item['tag']);
    echo json_encode($item);
}
