Question

I store backups of databases in a directory structure

year/month/day/time/backup_name

an example would be

basics_mini/2012/11/05/012232/RATIONAL.0.db2inst1.NODE0000.20110505004037.001 basics_mini/2012/11/06/012251/RATIONAL.0.db2inst1.NODE0000.20110505003930.001

note that timestamp from the backup file cannot be used. Before the automation testing starts the server time is set to 5.5.2011

So the question is how I can get the latest file if I pass the “base directory” (basics_mini) to some function that I am going to code. My thoughts are that I list the base directory and sort by time to get the year. Then I do the same for month, day and time.

I wonder if there is any “easier” solution to that in php.

Answer 1

Well, you can fetch whole directory tree at once and get last elem from it:

$baseFolder = './backup_mini' ;

$arr = glob("{$baseFolder}/*/*/*/*", GLOB_ONLYDIR);
$lastDir = array_pop($arr);
