If you want to display the first characters from a string in PHP, use “substr”.
Check the example.
1 2 3 | <html> $myfile_raw = substr($myfile_raw, 0, 5000); |
It will return the first 5000 characters from the string.
If you use:
2 3 4 | <html> $myfile_raw = substr($myfile_raw, 50, 5000); |
It will echo the characters starting from 50 to 5000.
