PHP 5.2 array_push 插入空值

Question

您好，我在迭代和推送数组中的值时遇到了一个奇怪的问题（为了更好地查看，我使用 json 数据）。下面是我在我的 foreach 中使用的数据，用于下面的数据。我实际上不知道问题是什么，但我正在使用 php 5.2

doc_no2: "1400010004"
}
]

这是我的代码

public function create($aData)
{

    $aValues = array();


    foreach ($aData as $key => $aReport) 
    {


        $sData = implode(',', $aReport);


        array_push($aValues, "(". $sData. ")");

    }
    echo json_encode($aValues);die();


}

当我回显 $aValues 时，这里是输出

[
null,
"(SOLD,1000004711,PAZ PHARMACY,1000004711,PAZ PHARMACY,20,Pharma Sales,E000071970,IGLORIA, JOAN DELICANO,DA,20170707,1700004713,1400009658,5120008912,RC - RECLASS,72783.62,8734.0344,64049.5856,INDEPENDENT,Reg Accnt-Non-Chain,0000123001,TRADE RECEIVABLE,,RC - Tech Reason,RC - Tech Reason,09,001,2017,1,1400009658)",
null,
null
]

Answer 1

它们显示为空，因为 json_encode 数据失败（格式不正确？）。确保您传递的数据格式正确，以便进行编码。
