Get first and last 100 characters of a text file

Question

I have a text file and within that text file, there are just few lines but contains about 5-10 million characters. I'm using file_get_contents but because it reads the whole file so the performance become very slow and hangs sometimes when executing. Is there a more efficient way to get first and last 100 characters?

Answer 1

try this to get first 100 characters:

$fp = fopen('test.txt', 'r');
$data = fread($fp, 100);
echo $data;
fclose($fp);

and get last 100 characters:

$fp = fopen('test.txt', 'r');
fseek($fp, -100, SEEK_END);
$data = fread($fp, 100);
echo $data;
fclose($fp);
