You also need to create stored functions to simulate the built-in date functions provided by MySQL, which is not recommended. If you want to store a date value that is out of this range, you need to use a non-temporal data type like integer e.g., three columns, and each column for the year, month, and day. MySQL uses 3 bytes to store a DATE value. Instead, you follow the standard date format and use the DATE_FORMAT function to format the date the way you want. This format is fixed and it is not possible to change it.įor example, you may prefer to use mm-dd-yyyy format but you can’t. MySQL uses yyyy-mm-dd format for storing a date value. MySQL DATE is one of the five temporal data types used for managing date values. As you've seen, you can generally just use the SQL 'NOW()' function to insert into a SQL timestamp field, but if that doesn't work for some reason, you can also create a timestamp field in the proper format using just PHP and the date function.Summary: in this tutorial, we will introduce you to the MySQL DATE data type and show you some useful date functions to handle the date data effectively. I hope these timestamp examples have been helpful. Please see that page for more information on creating other dates and times (I'm mostly just worried about "now" at this moment).

You can then use this formatted timestamp string in a PHP MySQL insert. If you print this out, your $timestamp field will now contain contents like this: However, if you want to do this all in PHP (or need to, depending on what framework you're working with), you can get the current date and time in the proper format using just PHP, like this: So that’s one way to populate a SQL timestamp field in a SQL INSERT query. I just tested this with PHP and MySQL, and it works fine. (user_id, name, last_updated, date_created) If you’re using plain old PHP and a database like MySQL, you can use the SQL now() function to insert data into a SQL timestamp field like this: Note: You might not need to create a PHP dateįirst off, you may not need to create a date in PHP like this.
