How to get the Date from Filenames?

[lopes_andre]

Hi,

 

I have the following situation:

 

Array ( 
[5] => GeoLiteCity_20090601.zip 
[6] => GeoLiteCity_20090701.zip 
[7] => GeoLiteCity_20090801.zip 
[8] => GeoLiteCity_20090901.zip 
[9] => GeoLiteCity_20091001.zip 
[10] => GeoLiteCity_20091101.zip 
[11] => GeoLiteCity_20091201.zip 
[12] => GeoLiteCity_20100101.zip 
[13] => GeoLiteCity_20100201.zip 
[14] => GeoLiteCity_20100301.zip 
[15] => GeoLiteCity_20100401.zip 
[16] => GeoLiteCity_20100501.zip 
[17] => GeoLiteCity_20100601.zip 
[18] => GeoLiteCity_20100701.zip 
[19] => GeoLiteCity_20100801.zip 
[20] => GeoLiteCity_20100901.zip 
[21] => GeoLiteCity_20101001.zip 
[22] => GeoLiteCity_20101101.zip 
[23] => GeoLiteCity_20101201.zip 
     ) 

 

I have this array with filenames, the patern for the name of the file is NAME_DATE.zip

 

I need to get from this array the most recent file(GeoLiteCity_20101201.zip). Which is the best way of doing this task?

 

Give me some clues.

If the last index of that array is always the latest file, you could just use:

$latest = array_pop($files);

Depending on how you sorted.
