Question

在我的项目中我使用excel表插入数据，但我无法将日期格式数据插入mysql。这是我的代码。我给出了完整的代码以便更好地理解。 dob和join_date在日期格式中。

<?php session_start();

我的excel表是。

我正在获取dob和join_date中所有记录的毛坯。

Answer 1

通常，Excel“日期”是MS序列化时间戳，衡量自1900年1月1日（或1904年1月1日，如果在Apple Mac版MS Excel上创建）以来的天数....这不是一个unix时间戳，也不是格式化的日期字符串。

PHPExcel提供了许多方法，可以将这个日期转换为unix时间戳，或者转换为PHP DateTime对象，然后可以将其格式化以便输入SQL语句。

假设情况属实，那么对于列N和P，您需要使用

$dto = PHPExcel_Shared_Date::ExcelToPHPObject($cell->getValue());

然后您可以使用DateTime对象的format()方法转换为Y-m-d格式化字符串

或

$dto = PHPExcel_Shared_Date::ExcelToPHP($cell->getValue());

转换为unix时间戳，然后可以使用date()

进行格式化

excel日期格式不插入mysql
