Why Does Using PHP\'s `date()` Function with \'Y-M-D G:i:s\' Format Fail to Insert into MySQL\'s Datetime Column?

MySQL Datetime Format Requirement for PHP's date() Function

When attempting to insert the result of the PHP date() function into a MySQL datetime type column, it's crucial to specify the correct format. Using the format 'Y-M-D G:i:s' may result in the insertion of "0000-00-00 00:00:00" instead of the intended date and time value.

Solution

The reason for this is the use of 'M' and 'D', which represent textual representations of the month and day. MySQL, however, expects a numeric representation of the date and time, in the format 'YYYY-MM-DD HH:MM:SS'.

To resolve this issue, modify the date() function to use 'm' and 'd', which represent the numeric equivalents. The correct format to use would be 'Y-m-d H:i:s'.

Additionally, it's recommended to use G to represent the 12-hour format and H to represent the 24-hour format. Leading zeros should also be included for consistency. Therefore, the final corrected format would be 'Y-m-d H:i:s'.
