我怎麼能爆多維數組

Question

我從檢索數據庫，保存多維array..i要添加

數組值| array..i的

兩者之間成員值試圖這提在什麼我試圖結束基本破滅功能..

我有環提及下面

$sql = "SELECT `categories` FROM `jos_js_res_record` WHERE `categories` LIKE '%Autumn Market Session%' OR `categories` LIKE '%Farmer Market Profiles%' OR `categories` LIKE '%Spring Market Session%' OR `categories` LIKE '%Summer Market Session%' OR `categories` LIKE '%Winter Market Session%' ORDER BY `user_id`"; 

$db->setQuery($sql); 

$unserial = $db->loadObjectList(); 

foreach ($unserial as $dataElement) { 
    $categories = unserialize($dataElement->categories); 

if (is_array($categories)) { 

foreach ($categories as $unserKey => $unserailData) { 

print $unserailData; 
    } 

} 

echo '<br />'; 

} 

我試圖下面的代碼行在每個循環的第二行但顯示錯誤

$comma_separated = implode(",", $unserailData); 

請引導我如何解決第二個數組中的值$ unserailData？

在$ unserailData數據看起來像下面

Answer 1

以下應該工作，如果我正確讀取您的要求：

$sql = "SELECT `categories` FROM `jos_js_res_record` WHERE `categories` LIKE '%Autumn Market Session%' OR `categories` LIKE '%Farmer Market Profiles%' OR `categories` LIKE '%Spring Market Session%' OR `categories` LIKE '%Summer Market Session%' OR `categories` LIKE '%Winter Market Session%' ORDER BY `user_id`"; 

$db->setQuery($sql); 

$unserial = $db->loadObjectList(); 

foreach ($unserial as $dataElement) { 
    $categories = unserialize($dataElement->categories); 
    if (is_array($categories)) { 
     echo implode('|', $categories); 
    } elseif (is_string($categories)) { 
     echo $categories; 
    } 
    echo '<br />'; 
}

我作出了以下伎倆，但在代碼中提到@Robbie更乾淨，所以我與他的代碼替換我的代碼。

我做這一招

foreach ($unserial as $dataElement) { 
    $categories = unserialize($dataElement->categories); 
if (is_array($categories)) 
{ 
foreach ($categories as $unserKey => $unserailData) { 
$arr2[] = $unserailData; 
} 
$imploded = implode(" | ", $arr2); 
print_r($imploded); 
$arr2 = array(); 
} 

else{ 
echo "Category not stored correctly"; 
} 
echo '<br />'; 
}
