如何将j / m / y日期格式更改为时间戳？

Question

I tried convert to timestamp but not working, My code is below

$date = $objPHPExcel->getActiveSheet()->getCell('A' . $x)->getFormattedValue();//output value is 9/Feb/16

echo strtotime($date);//return value is empty

It's return empty value. I want to compare Excel sheet date and PHP returned date. Excel sheet returned date is like this -> 9/Feb/16

Answer 1

You just need to change slashes to minus symbol so strtotime will recognize you $date as date

$date = str_replace('/','-',$date);
echo strtotime($date); //output 1454976000

Answer 2

If the value in the cell is an MS Excel serialized timestamp, then you can get the "raw" value from the cell

$date = $objPHPExcel->getActiveSheet()
    ->getCell('A' . $x)->getValue();

which should return a number like 42409 for 2nd February 2016

Then use the built-in date/time conversion functions to convert that either to a unix timestamp, or to a PHP DateTime object

$date = PHPExcel_Shared_Date::ExcelToPHP($date); // returns a unix timestamp
echo date('Y-m-d H:i:s', $date);

or

$date = PHPExcel_Shared_Date::ExcelToPHPObject($date); // returns a DateTime object
echo $date->format('Y-m-d H:i:s');

Answer 3

$d = DateTime::createFromFormat('j/M/y', '9/Feb/16');
echo $d->getTimestamp();
