foreach ($array as $date => $entries) { 
    foreach ($entries as $entry) { 
     if ($entry['category_slug'] == 'shopping') { 
      echo $date; // or return, or whatever 
      break 2; 
     } 
    }

使用簡單foreach

$keyword = 'shopping'; 
foreach ($arr1 as $k=>$arr) 
{ 
    foreach($arr as $k2=>$arr2) 
    { 
     if($arr2['category_slug']==$keyword) 
     { 
      echo $k; 
      //break; //<--- Uncommented since you need all the entries 
     } 
    } 
}

嘿我得到正確的輸出，但它不破它是未來多時間。如何打破它。價值不是固定時間。它可以變化。 – Muk

使用代碼中顯示的'break'。你看過演示了嗎？ –

是的，我已檢查演示。我想所有的日期，在循環不僅一個，我得到所有日期，但多次。我也使用break.please幫助我 – Muk

試試這個

// $ARR_INPUT is your array 

$keyword_search = "shopping"; 
$key_to_search = "category_slug"; 

$flag = 0; 
$output = ""; 
foreach($ARR_INPUT as $key1=>$arr1) 
{ 
    foreach($arr1 as $key2=>$arr2) 
    { 
     if($arr2[$key_to_search] == $keyword_search) 
     { 
      $output = $key1; 
      $flag = 1; 
      break; 
     } 
    } 
    if($flag==1) 
    { 
     break; 
    } 
} 

echo "Output : ".$key1;
