they both do exactly the same - there is no better or worse Smilie
btw - it is almost always a bad idea to increase the hard limits for a non-root user ... and to set nofiles to unlimited

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. List of possible limits returned +-----------+---------------------------------------------------+ |Limit name | | | | | | | Limit description | | | | +-----------+---------------------------------------------------+ | core | | | | | | | The maximum size of the core file. When 0, not | | | core files are created. When core files are | | | larger than this size, they will be truncated at | | | this size. | | | | | totalmem | | | | | | | The maximum size of the memory of the process, | | | in bytes. | | | | |virtualmem | | | | | | | The maximum size of the virtual memory for the | | | process, in bytes. | | | | | data | | | | | | | The maximum size of the data segment for the | | | process, in bytes. | | | | | stack | | | | | | | The maximum size of the process stack, in bytes. | | | | | rss | | | | | | | The maximum number of virtual pages resident in | | | RAM | | | | | maxproc | | | | | | | The maximum number of processes that can be cre- | | | ated for the real user ID of the calling process. | | | | | memlock | | | | | | | The maximum number of bytes of memory that may | | | be locked into RAM. | | | | | cpu | | | | | | | The amount of time the process is allowed to use | | | the CPU. | | | | | filesize | | | | | | | The maximum size of the data segment for the | | | process, in bytes. | | | | |openfiles | | | | | | | One more than the maximum number of open file | | | descriptors. | | | | +-----------+---------------------------------------------------+ EXAMPLES
Example #1 Example use of posix_getrlimit(3) <?php $limits = posix_getrlimit(); print_r($limits); ?> The above example will output something similar to: Array ( [soft core] => 0 [hard core] => unlimited [soft data] => unlimited [hard data] => unlimited [soft stack] => 8388608 [hard stack] => unlimited [soft totalmem] => unlimited [hard totalmem] => unlimited [soft rss] => unlimited [hard rss] => unlimited [soft maxproc] => unlimited [hard maxproc] => unlimited [soft memlock] => unlimited [hard memlock] => unlimited [soft cpu] => unlimited [hard cpu] => unlimited [soft filesize] => unlimited [hard filesize] => unlimited [soft openfiles] => 1024 [hard openfiles] => 1024 ) NOTES
Note This is a not POSIX function, but is common on BSD and System V systems. If the system does not support this function, then it will not be included at compile time. This may be checked with function_exists(3). SEE ALSO
