note 56514 modified in function.filesize by betz

A different way to get the filesize using a shell 'hack' (and therefore make your code somewhat platform dependent) is to do the following: <?php $file = "/test/file/location/test.txt"; $filesize = exec("du -h ${file}"); preg_match("/^([0-9\.]+[a-zA-Z]?)[\s]+[.*]/", $filesize, $matches); $filesize = $matches[1]; ?> The regex could probably be cleaner but it does the job. Note that the -h parameter I use here automatically formats the file size. Hence when I run this on an example file the value in $matches[1] is: 7.6M If you just want the raw size in bytes (but without problems when you hit 2 gig etc.) then remove the -h parameter from the exec line. --was-- [Self correction of my previous post, if admin could delete the earlier one it would be most appreciated] A different way to get the filesize using a shell 'hack' (and therefore make your code somewhat platform dependent) is to do the following: <?php $file = "/test/file/location/test.txt"; $filesize = exec("du -h ${file}"); preg_match("/^([0-9\.]+[a-zA-Z]?)[\s]+[.*]/", $filesize, $matches); $filesize = $matches[1]; ?> The regex could probably be cleaner but it does the job.
