php删除foreach中的重复值

Question

I have a foreach iterator, there are 500 group items in it. How do I remove duplicate values in a foreach?

foreach ($data as $data) {
if(!empty($data['name'])){  //check if have $data['name']
$name = $data['name'];
$id = $data['id'];
$date = $data['date'];
$link = $data['link'];
if(strpos($link, '.ads.')){
continue; //remove all the link contains `.ads.`
}else{
// if `$link` is not repeat, echo the below data. how to use array_unique, remove all the values which repear in `$link` part? 
echo $name;
echo $id;
echo $date;
echo $link;
} 
}

Answer 1

With array_unique:

foreach (array_unique($data) as $d) {
 // Do stuff with $d ...
}

Although you can technically call the array and its elements by the same name, it's bound to lead to programming errors and confusion afterwards.
