I am trying to upload an excel spreadsheet with a column that contains dates and also other text.

the date is in the format 1/24/2012 but when i load it into mysql it changes it to some decimal format e.g. 40932 ????

how can i just upload it as is, without it changing? o

What can i do i'm really stuck on this one!!!!

Any help would be most appreciated.

Excel holds date values as the "real" number of days since a base date, which can be either 1st January 1900 (the default for Windows versions of Excel) or 1st January 1904 (the default for Mac versions of Excel): the time is the fractional part, so midday on any given date is 0.5 greater than midnight. To add to the misery, Feb29th 1900 is a valid date for the Windows 1900 calendar.

Assuming the Windows 1900 calendar:

function ExcelToPHP($dateValue = 0) {

$myExcelBaseDate = 25569;

// Adjust for the spurious 29-Feb-1900 (Day 60)

if ($dateValue < 60) {

--$myExcelBaseDate;

}

// Perform conversion

if ($dateValue >= 1) {

$utcDays = $dateValue - $myExcelBaseDate;

$returnValue = round($utcDays * 86400);

if (($returnValue <= PHP_INT_MAX) && ($returnValue >= -PHP_INT_MAX)) {

$returnValue = (integer) $returnValue;

}

} else {

$hours = round($dateValue * 24);

$mins = round($dateValue * 1440) - round($hours * 60);

$secs = round($dateValue * 86400) - round($hours * 3600) - round($mins * 60);

$returnValue = (integer) gmmktime($hours, $mins, $secs);

}

// Return

return $returnValue;

} // function ExcelToPHP()

if Mac 1904 base, replace

$myExcelBaseDate = 25569;

// Adjust for the spurious 29-Feb-1900 (Day 60)

if ($dateValue < 60) {

--$myExcelBaseDate;

}

with

$myExcelBaseDate = 24107;

This will return a PHP date/time value (standard 1970 base date), that you can then format as you wish using date();
