Could you please give some examples?

Hello,

I'm just a new PHP self-learner, and so curious about how is this tool works?
How can i use it?

I have did this line.
$mmap = mmap_open('new.txt', 1024, 0);

but what's next?
print_r($mmap); ? it give nothing.

Thanks for your time.

@SSDMAD in your case $mmap will be a stream resource that can be used with fread(), fwrite(), fseek() and fclose()

@calcinai Thank you for your time.

Its work for me now. like so.

$filename = "a.txt";
$mmap = mmap_open($filename, filesize($filename), 0);
while($contents = fread($mmap, 1024){
	echo $contents."\n";
}
fclose($mmap);

I just want to ask more. Did it should have fclose($mmap) or its not necessary? and did this will make files so fast to read as expected in C? And one more question, Can i read the file line by line? or i have to explode the contents?
