Question

I’ve got a really simple problem but I just can’t sort it, fairly new to PHP and MySQL which is why im struggling

Overview – I want to insert an ISO8601 date into MySQL DB table using PHP

I have a text.xml file that has a timestamp (under MeanPublic) in which is ISO8601 format, i.e. YYYY-MM-DDTHH:MM:SS

I can read the file in PHP, I can echo that ISO8601 date, however, if I insert it into MySQL it just logs 0000-00-00 00:00:00. I’ve tried stripping the “T” out of the date but doesnt work.

Ive tried setting the database table field in vchar, char, int, date, datetime, and time, just nothing. However, if I put in the insert a manual date/time it inserts ok.

It’s crucial that it logs as date/time because I need to run date/time queries later on these values

Here’s the code

if( ! $xml = simplexml_load_file('test.xml') ) 
    { 
        echo 'unable to load XML file'; 
    } 
    else 
    { 
        foreach( $xml as $MeanPublic ) 
        {
        $key = split(":", $MeanPublic->Key);
        $meanvalue = $MeanPublic->Mean;
        $FTSvalue = str_replace('T', ' ', $MeanPublic->Timestamp);

mysql_query("INSERT INTO table (totwhout, wbstamp) VALUES ($meanvalue, $FTSvalue)");
       }

Answer 1

You’ve probably already checked this, but are you putting single quotes around the timestamp value when constructing the query? Judging from your posted code, it doesn’t look like you are — MySQL expects the TIMESTAMP values to be passed like strings in that regard.
