Glad I could help. The problem you faced earlier could happen if you tried to use the timestamp column values directly in the php date() function. If you see the database your timestamp columns would have values in the following format for its timestamp columns: '1970-01-01 00:00:01' This isn't the same as the unix timestamp integer value. -----Original Message----- From: Stephen Sunderlin [mailto:stephen.sunderlin@xxxxxxxxxxx] Sent: Saturday, September 22, 2007 11:27 PM To: 'Naintara' Cc: 'PHP-DB Mailing List' Subject: RE: Notice: A non well formed numeric value encountered Naintara, That worked! I must have made a syntax error.

Look it up in the MySQL reference, it's very easy to use. You'll have something like contact_created_date If a contact was created today, it'll be something like SELECT DATE_FORMAT(contact_created_date, '%M %d, %Y'); =>September 22, 2007 Where contact_created_date is your field. -----Original Message----- From: Stephen Sunderlin [mailto:stephen.sunderlin@xxxxxxxxxxx] Sent: Saturday, September 22, 2007 10:38 PM To: 'Naintara'; 'PHP-DB Mailing List' Subject: RE: Notice: A non well formed numeric value encountered I have 3 Timestamp fields in a contact manager that record Edit date, Create Date and Merge Date. Doesn't matter to me how it is stored at this point however when I tried to call it up as just Month, Day, Year (with out the timestamp) in php I got the "A non well formed numeric value encountered" NOTICE. You say I can convert a mysql timestamp value at will in the program (which I think I am trying to do) and it is not working. Must I convert it with a MYSQL function or a PHP function. Any other ideas? -----Original Message----- From: Naintara [mailto:naintara@xxxxxxxxxxxx] Sent: Saturday, September 22, 2007 12:49 PM To: 'PHP-DB Mailing List' Subject: RE: Notice: A non well formed numeric value encountered That's a good question. I'm really not sure about which way is better, but yes, you could use UNIX_TIMESTAMP() to query a datetime value from a MySQL field, convert it to the UNIX timestamp value within the query, and then retrieve it in your record set. UNIX_TIMESTAMP() [MySQL function] Or you could use php to convert a datetime value to UNIX timestamp. mktime() [php function] You could store the timestamp value in the database itself, and convert at will in the program. So many choices... I really wouldn't know which to recommend, a lot depends on usage. The datetime column takes more storage than an integer column, but it's human-readable. If you mean storing an timestamp integer value in a particular database field, that should also be fine. There are a whole lot of issues with datetime related functions, like DST (daylight savings time) or timezones, if all that is critical, you may look into it. There is a TIMESTAMP field type in MySQL, the usage has changed in MySQL 4.1 and up. This is useful for recording time/date of db updates. For usual work, I find that a datetime data type column works for me. Then, if I know what I will be using the datetime value for, I sometimes format the date within the query itself using DATE_FORMAT() as I like to get the results that way rather than change it, of course, if you may be presenting the datetime value in different ways, or if you want the flexibility, then use php. I hope this helps somewhat. -----Original Message----- From: Stephen Sunderlin [mailto:stephen.sunderlin@xxxxxxxxxxx] Sent: Saturday, September 22, 2007 9:24 PM To: 'Naintara'; 'PHP-DB Mailing List' Subject: RE: Notice: A non well formed numeric value encountered Thank you for your response. The notice is in the Subject Line of the email: Notice: A non well formed numeric value encountered So you are saying I have to convert the current yyyy-mm-dd:HH:MM:SS date format, to UNIX timestamp value then call Date() to format the UNIX timestamp as Month, Day, Year? If so, is it recommended to do that at the database level or the program level. I guess it would make sense to convert all dates to UNIX timestamp for database storage then convert at necessary. Any insight would be helpful.

Perhaps a timezone notice? Lookup the date() function in the php manual. The time parameter should be a unix timestamp value, so $CTS should contain an integer value. You can also find ways to convert the time value you have to unix timestamp, in the manual. -----Original Message----- From: Stephen Sunderlin [mailto:stephen.sunderlin@xxxxxxxxxxx] Sent: Saturday, September 22, 2007 7:48 PM To: 'PHP-DB Mailing List' Subject: Notice: A non well formed numeric value encountered I'm getting the above NOTICE with the following statement: Echo date('d/m/y',$CTS); Where $CTS = 2007-09-22 10:09:31 And 31/12/69 is being echoed.
