Question

If I have a table that has a TIMESTAMP column, and I want to retrieve only the rows that were added after a php variable that was set by $time=strtotime(“now”) was created, how would I format the query syntax?

$q= “SELECT * FROM webchat_lines WHERE author = ‘someone’ *{between $time and CURRENT_TIMESTAMP}* ORDER BY id DESC LIMIT 20″;

Answer 1

Try:

$q = "SELECT *
      FROM webchat_lines
      WHERE author='someone'
        AND timestamp BETWEEN FROM_UNIXTIME($time) AND NOW()
      ORDER BY id DESC
      LIMIT 20";

This uses FROM_UNIXTIME($time) to convert the strtotime output (seconds since 1970-xx-xx etc) to a date so it can be compared to your timestamp column. NOW() is an alias for CURRENT_TIMESTAMP().
