php - 基于值唯一的多维数组(不是数组键)

Question

<分区>

Answer 1

$input = array( /* your data */ );
$temp  = array();
$keys  = array();

foreach ( $input as $key => $data ) {
    unset($data['id']);
    if ( !in_array($data, $temp) ) {
        $temp[]     = $data;
        $keys[$key] = true;
    }
}

$output = array_intersect_key($input, $keys);

或

$input = array( /* your data */ );
$temp  = $input;

foreach ( $temp as &$data ) {
    unset($data['id']);
}

$output = array_intersect_key($input, array_unique($temp));
