PHP转换数组以逗号分隔的字符串

Question

I can't seemn to make this work could someone help identify what is incorrect:

$result = mysql_query("SELECT accounts_client_email.client_email FROM accounts_client_email WHERE accounts_client_email.accounts_client_id = 1", $con);

while( $row = mysql_fetch_assoc( $result)){
$new_array[] = $row; // Inside while loop
}

$tags = implode(', ', array($new_array));

echo $tags;

Answer 1

You aren't adding correctly to the array, it should be:

$new_array[] = $row['client_email'];

And you are encapsulating the array into another array unnecessarily;

use:

$tags = implode(', ', $new_array);

Or echo $tags; will just output "Array"
