如何摆脱重复的价值......

foreach($get_all as $key => $value) 
    {
        $v = 1;
        foreach($value as $loc) 
        {
            foreach($loc as $l)
            {
                $new[] = $l['id'];
            }
        }
        $new = array_unique($new);  
        $total = count($new);   
        unset($new);
        if($v)
        {
            $v =0 ;
            $body .= "<tr><td>{$value[0][0]['location']}</td><td>{$total}</td></tr>";
            continue;
        }
    }

上面的代码给出了输出：

Koramangala 63
Koramangala 63
Indiranagar 36
Koramangala 63
Indiranagar 36
MG Road 16
Koramangala 63
Indiranagar 36
MG Road 16
BTM 35

但我需要的是：

Koramangala 63
    Indiranagar 36
    MG Road 16
    BTM 35

我需要什么来获得所需的输出？/ ??

你可以这样做

$printed = array(); // initialize an array to store the printed values
foreach($get_all as $key => $value) 
{
    $v = 1;
    foreach($value as $loc) 
    {
        foreach($loc as $l)
        {
            $new[] = $l['id'];
        }
    }
    $new = array_unique($new);  
    $total = count($new);   
    unset($new);
    if($v)
    {
        $v =0 ;
        if (!in_array($value[0][0]['location'], $printed)){ //check if not already printed
            $body .= "<tr><td>{$value[0][0]['location']}</td><td>{$total}</td></tr>";
            $printed[]=$value[0][0]['location']; //store the printed location to the array
        }
        continue; //this is not required as it is the last line
    }
}

注意：我不知道您使用$v的原因（可能您只发布了相关部分）。您的数据结构不明确，因此这可能不是最佳（优化）选项。
