On Windows NT, using Apache tested in PHP 4.0.1PL2, 4.0.2 for Win NT using
Apache CGI PHP. The function date() with MySQL date format of
YYYY-MM-DD HH:MI:SS
yields an error when using dates with a value lower than 1970-01-01 00:00:00.
The following error is actually reported:
Warning: unexpected error in date() in Program.php line XXX
Below is a script which reproduces this error:
$db_birth_date = "1969-09-13 00:00:00";
$birth_date = $parseDate($db_birth_date',"F j, Y");
function parseDate($date,$format) {
$dateString = date($format , strtotime($date));
return $dateString;
}
Have not tested this issue on UNIX system yet.

Your example code was buggy, below corrected one: <?php function parseDate($date,$format) { $dateString = date($format , strtotime($date)); return $dateString; } $db_birth_date = "1969-09-13 00:00:00"; $birth_date = parseDate($db_birth_date,"F j, Y"); echo $birth_date; ?> And this works just like it should (in Linux).. Please try this and report back. --JaniUser feedback: --------------------------- I was actually contacted on this issue once, and sent a corrected reply as follows. Keep in mind, this issue only occurs in _Windows_ versions of PHP including PHP 4.0.1pl2 and 4.0.2. UNIX varients do not seem effected.: I've written a specific script to show this issue: --- cut --- <?php for ( $i = 1900; $i < 2050; $i++) { $datep = "$i-01-01"; print "Trying: $datep ... "; print date("F j, Y", strtotime($datep)); print "<BR>"; // For clean display sake only } ?> --- cut --- I also tested this with dates in 12-31, and 1969 failed, so 1970-01-01 is the lowest possible date: --- cut --- Trying: 1900-01-01 ...

January 1, 1974 --- cut --- It seems likely that the date() function uses internal calls within the O/S somehow on Windows, as this would correlate to what Windows/MSDOS is (in)capable of doing. However, it hardly seems to be a desirable side-effect in a production quality programming language. Anyhow, let me know if there is other documentation you need from me. --------------------------------------- Editorial note: PLEASE answer next time using the web-interface.. =) --Jani
