Question

I’m very new in PHP, and would like to do a foreach loop that won’t repeat a result if the same item has been output before.

Here’s my code:

    foreach ( $attachments as $id => $attachment ) {
        echo ($attachment->post_title);
    }

As you can see, the word would be pulled by echo ($attachment->post_title);.

Is there a way to do some checking and avoid duplicates?

Many thanks for your help.

$outputted = array();

foreach($attachments as $id => $attachment) {
   if (!isset($outputted[$attachment->post_title])) {
      echo $attachment->post_title;
      $outputted[$attachment->post_title] = true;
   }
}
