I want clear the repeat values. here is the answer form Tomalak Geret'kal, thanks him. It can clear the repeat name.

$names = Array();

foreach ($status_list['data'] as $data) {
   $names[] = $data['name'];
}

$names = array_unique($names);  // not print the same name.

foreach ($names as $name) {
   echo $name;
}

for I still want to echo $id. I tired 2 method here:

$names = Array();

foreach ($status_list['data'] as $data) {
   $names[] = $data['name'];
   $id[] = $data['id'];
}

$names = array_unique($names);  // not print the same name.

foreach ($names as $name) {
   echo $name;
   echo $id; // no result
}



$names = Array();

foreach ($status_list['data'] as $data) {
   $names[] = $data['name'];
}

$names = array_unique($names);  // not print the same name.

foreach ($names as $name) {
   echo $name;
   echo $data['id']; // all the id is the last people. 
}

How to do the right method? Thanks.

Try this:

$data = array_unique($status_list['data']);

foreach ($data as $i) {
    echo $i['name'];
    echo $i['id'];
}

By using $names = array_unique($names); you only put all the names in the array $names.

EDIT: well i agree with Tomalak Geret'kal, cause it makes no sense to echo the ID but you could try the following:

foreach ($status_list['data'] as $data) {
   $names[] = $data['name'];
   $ids[] = $data['id'];
}

$names = array_unique($names);  // not print the same name.
$ids = array_unique($ids);  // not print the same name.

$i = 0

foreach ($names as $name) {
    echo $name;
    echo $ids[$i];
    $i ++;
}

This makes no sense.

You only had duplicates because you were discarding all information other than "Name", which was not a unique field.

When you bring the id field (which is unique) into the picture, you no longer have any duplicates in the result.

So, just write:

foreach ($status_list['data'] as $data) {
   echo $data['name'] . " " . $data['id'] . "
";
}

$names = Array();
$names=array("0"=>1,"1"=>"1","2"=>"2","3"=>"2","4"=>"23"); //same value in array

$names = array_unique($names);  // not print the same name.

foreach ($names as $name) {
      echo "
".$name;
}
