PHP中如何给数组id值添加CUS字符串前缀 实现拼接输出

要实现固定前缀CUS和查询得到的ID拼接，仅需修改数组中id字段的赋值逻辑，使用PHP的字符串拼接运算符.连接两个值即可，修改后的完整代码如下：

while ($row = mysqli_fetch_assoc($empRecords)) {
$data[] = array(
        "id"=> "CUS" . $row['id'],
        "name"=>$row['name'],
        "id_no"=>$row['id_no'],
        "address"=>$row['address'],
        "grmadiv"=>$row['grmadiv'],
        "mobile"=>$row['mobile'],
        "branch"=>$row['branch'],
        "loanOfcr"=>$row['loanOfcr'],
        "collectOfcr"=>$row['collectOfcr']
    );
}

如果后续业务需要用到纯数字格式的原始ID，也可以新增一个字段单独存储，避免后续需要拆分前缀的麻烦：

// 新增origin_id字段保存原始数字ID示例
while ($row = mysqli_fetch_assoc($empRecords)) {
$data[] = array(
        "id"=> "CUS" . $row['id'],
        "origin_id"=> $row['id'],
        "name"=>$row['name'],
        "id_no"=>$row['id_no'],
        "address"=>$row['address'],
        "grmadiv"=>$row['grmadiv'],
        "mobile"=>$row['mobile'],
        "branch"=>$row['branch'],
        "loanOfcr"=>$row['loanOfcr'],
        "collectOfcr"=>$row['collectOfcr']
    );
}
