我将表单发布数据以数组格式存储在 MySQL 数据库中，但是当我获取值时它不是数组，它变成了字符串。

有我的取值：

Array ( [First_Name] => Rahul [Last_Name] => Singh [Street] => 210 Adhichini [City] => New Delhi [California_Automobile_Insurance_Quote] => California Automobile [ZIP_/_Postal_Code] => 110092 [E-Mail_Address] => rahulsingh4ut@gmail.com [Primary_Phone_Number] => 8470016156 [Alternate_Phone_Number] => 7503963073 [Date_of_Birth] => 25/05/1990 [Marital_Status] => Single [License_(State,_Number)] => DLI123 [Year] => 2012 [Make] => TVS [Model] => Apache 160 [VIN] => TVS123 [Cylinders] => CY000 [Do_you_rent_or_own_your_home?] => Rent [Do_you_currently_have_insurance?] => No [Current_Insurance_Provider] => No I. Prov [last_insurance] => No [Comprehensive_Deductible] => No [Collision_Deductible] => No [Bodily_Injury_Liability] => Bodily [Property_Damage_Liability] => Property Damage [Uninsured_Motorist_Bodily_Injury] => Uninsured [Uninsured_Motorist_Property_Damage] => Motorist Property Da [Underinsured_Motorist_-_Bodily_Injury_Limits] => Motorist - Bodily [Underinsured_Motorist_-_Property_Damage_Limits] => 05 [Medical_Pay_/_PIP] => 2016 [Towing] => Delhi [What_percentage_of_your_vehicles_total_use_time_is_driven_by_you?] => 45 [How_many_miles] => 15000 [accidents_or_minor_violations] => 5Yr )

MySQL 不支持array 数据类型将数据存储在列中。

标签： php mysql arrays

【解决方案1】：

我认为您使用序列化函数将数据发布到数据库并使用反序列化函数检索数据。这是最好的

$serialized_data = serialize(array('Math', 'Language', 'Science'));  
echo  $serialized_data . '<br>';

【解决方案2】：

您不能真正在 MySQL 中存储数组，但是您可以选择将数组转换为 JSON String 或 Serialized String。很难想象在 MySQL 数据库中存储 Array... 你可以这样做（例如）：

<?php
     // THIS IS JUST AN EXAMPLE, IN REALITY, YOU HAVE TO CLEAN UP
     // ALL THE DATA COMING FROM YOUR $_POST GLOBAL TO AVOID RISKS OF SQL INJECTION.
     $postDataForDB = json_encode($_POST);
     // NOW YOU CAN SAVE THE RESULTING JSON ENCODED DATA TO DATABASE...

或者；您也可以像这样使用数据的序列化版本：

<?php
     // AGAIN; THIS IS JUST AN EXAMPLE, IN REALITY, YOU HAVE TO CLEAN UP
     // ALL THE DATA COMING FROM YOUR $_POST GLOBAL TO AVOID RISKS OF SQL INJECTION.
     $postDataForDB = serialize($_POST);
     // NOW YOU CAN SAVE THE RESULTING SERIALIZED DATA TO DATABASE...
