如何从文本文件中解析日期？

Question

I am parsing a date from a text file. Here my text file:

#Tue Jul 15 15:40:44 CEST 2015

This is how I am parsing it:

foreach ($linesArray AS $line) {
    if (strlen($line) && $line[0] == '#') {
       $date = strtotime(substr($line, 1));
       $strDate = date("y-m-d H:i:s", $date);
    }

But I get a different date as a result:

echo $strDate;

15-07-21 14:40:44

You need to always (mostly) specify what format are you parsing the date from. Basically, you need to build a string that works with your date format. All of the possible format parameter strings can be found here: http://php.net/manual/en/function.date.php

This should work for your date formatting:

$date = "Tue Jul 15 15:40:44 CEST 2015";
$formatted = DateTime::createFromFormat('* M d H:i:s T Y',$date);
var_dump($formatted->format("Y-m-d H:i:s"));
