Saving timestamp in mysql table using php

Question

I have a field in a MySQL table which has a timestamp data type. I am saving data into that table. But when I pass the timestamp (1299762201428) to

Answer 1

If I know the database is MySQL, I'll use the NOW() function like this:

INSERT INTO table_name
   (id, name, created_at) 
VALUES 
   (1, 'Gordon', NOW()) 

Answer 2

You can use now() as well in your query, i.e. :

insert into table (time) values(now());

It will use the current timestamp.

Answer 3

pass like this

date('Y-m-d H:i:s','1299762201428')

Answer 4

Some things to clarify:

• MySQL timestamp field type doesn't store unix timestamps but rather a datetime-kind value.
• UNIX timestamp is a number of a regular int type.
• The timestamp you're talking about is not a regular unix timestamp but a timestamp with milliseconds.

therefore the correct answer would be

$timestamp = '1299762201428';
$date = date('Y-m-d H:i:s', substr($timestamp, 0, -3));

Answer 5

This should do it:

  $time = new DateTime; 

Answer 6

I'm guessing that the field you are trying to save the value in is a datetime field it's not but the same seems to be true for timestamps. If so mysql expects the format to be Year-month-day Hour:minute:second. In order to save the timestamp you will have to convert the field to numeric using a query like

alter table <table_name> change <field> <field> bigint unsigned

If you are using the current time you can use now() or current_timestamp.
