php - PHP remove duplicates in foreach after substr results

Question

How can I remove the duplicates after my substr output in the foreach loop? Currently it outputs the stripped string in multiples. I would like the output to only list a unique "$workername" to avoid duplicates being listed

foreach ($block as $blocks) {
    $worker = $block['pools']['snowgem']['workers'];
    foreach($worker as $workers) {
        //$workers = array_unique($workers);
        $workername = substr($workers['name'], 0, strpos($workers['name'], "."));
        echo $workername."<br>";
    }
}

Sample output:

s1a5Ja3hPfP8FZgABzN8nYSU2uFgKetDTtL

使用一个数组来存储输出的值，并检查你是否已经输出了这个值

    $outputed_values = array();
    foreach ($block as $blocks) {
        $worker = $block['pools']['snowgem']['workers'];
        foreach($worker as $workers) {
            //$workers = array_unique($workers);
            $workername = substr($workers['name'], 0, strpos($workers['name'], "."));
            if (!in_array($workername, $outputed_values)){
               echo $workername."<br>";
               array_push($outputed_values, $workername);
            }
        }
     }
