如何从包含unix时间戳中的日期字段的表中获取记录？

Question

I am storing my date by using the time() function in PHP. I have a search section in my program.And the field for date is done by jquery datepicker. This is my date format eg: 14/12/2012.

The problem is the filed in table is timestamp. How can i select the actual date from this date string using MySQL query?

I am using codeigniter as framework. Is there any function to do this?

Please help me.

Answer 1

time() in PHP simply returns a unix time stamp - seconds since Jan 1/1970. MySQL timestamp, date, and datetime fields are NOT directly compatible with that value, but you can convert between the two easily:

SELECT UNIX_TIMESTAMP(yourtimestampfield) AS php_compatible_time_value, ...

Note that MySQL's date string format is yyyy-mm-dd . You cannot use your dd/mm/yyyy format unless you convert to MySQL's expected format.

Answer 2

$date = '14/12/2012';
$d = explode('/',$date);
$timestamp = mktime(0, 0, 0, $d[1], $d[0], $d[2]); 

And then you use $timestamp in your query

Of course you're gonna need different approaches for dates in different format UK/US etc. mm/dd/yyyy or dd/mm/yyyy
