Question

好的，所以我有这个阵列。目前，如果表付款中存在多个付款金额和日期，则会提取多个付款金额如上所述，它将它们分开。我只希望它能够提取第一个付款日期和金额。不是多个。我尝试过的一切都是在最后破坏事物。任何帮助，将不胜感激。我完全难过了。

'payment_info' => array(
    'field' => 'payment_dates, payment_amounts, recurring_amount', 
    'table' => 'LEFT JOIN 
                   (SELECT site_id, 
                       CONVERT(GROUP_CONCAT(start_date SEPARATOR ", ") 
                           USING latin1) AS payment_dates, 
                       CONVERT(GROUP_CONCAT(amount SEPARATOR ", ") 
                           USING latin1) AS payment_amounts 
                    FROM payments 
                    GROUP BY site_id 
                    ORDER BY start_date) AS payment_info
                ON sites.site_id = payment_info.site_id 
                LEFT JOIN 
                   (SELECT site_id, amount AS recurring_amount 
                    FROM recurring_payments 
                    GROUP BY site_id 
                    ORDER BY payment_id DESC) AS recurring_amount 
                ON sites.site_id = recurring_amount.site_id'
),

在你的回报中$ x = explode（'，'，$ row ['payments_dates']）;并使用$ x [0]

与payments_amounts相同

php mysql数组限制
