意外的T_FOREACH

Question

我試圖迴應這個Foreach，我不確定正確的方法來做到這一點。我已經嘗試在foreach中創建一個變量並對其進行迴應，但那隻會回顯數組的最後一個值。請讓我看看這樣做的正確方法：

$client->sendMsgSpecial("Glows Updated", "Your glows have succesfully been updated. The following have been updated: " . 
foreach($glows as $value) { 
echo $value . ', '; 
} 
. "", "glows"); 

Answer 1

試着用implode代替產生一個這樣的字符串。

$glowVar = implode(',', $glows); 
$client->sendMsgSpecial("Glows Updated", "Your glows have succesfully been updated. The following have been updated: " . $glowVar . ", "glows"); 

或者，如果想嘗試，然後用自己的方式 -

$str = ''; 
foreach($glows as $value) { 
    $str .= $value . ', '; 
} 
$client->sendMsgSpecial("Glows Updated", "Your glows have succesfully been updated. The following have been updated: " . $str . ", "glows"); 

Answer 2

不能呼應的方法調用。使用一個變量。

$message = "Your glows have succesfully been updated. The following have been updated: "; 
foreach($glows as $value) { 
    $message .= $value . ', '; 
} 

然後用變量調用你的方法。

$client->sendMsgSpecial("Glows Updated", $message, "glows"); 

簡短的回答，但希望它有幫助。
