filesize
I know in php if you use the function filesize it will return the size of the file in bytes, but is there an easy way to get the size in MB.
Cheers

posix_getrlimit
POSIX_GETRLIMIT(3) 1 POSIX_GETRLIMIT(3)
posix_getrlimit - Return info about system resource limits
SYNOPSIS
array posix_getrlimit (void )
DESCRIPTION
posix_getrlimit(3) returns an array of information about the current resource's soft and hard limits.
Each resource has an associated soft and hard limit. The soft limit is the value that the kernel enforces for the corresponding resource.
The hard limit acts as a ceiling for the soft limit. An unprivileged process may only set its soft limit to a value from 0 to the hard
limit, and irreversibly lower its hard limit.
RETURN VALUES
Returns an associative array of elements for each limit that is defined. Each limit has a soft and a hard limit.

| | core files are created. When core files are |

| | |
| | The maximum size of the memory of the process, |
