PHP preg_match (.*) not matching past line breaks

Try setting the regex to dot-all (PCRE_DOTALL), so it includes line breaks (the extra 's' parameter at the end):

preg_match('/Para(.*)three/s', $row['file'], $m);

Add the multi-line modifier.

Eg:

preg_match('/Para(.*)three/m', $row['file'], $m)

Use the s modifier.

preg_match('/Para(.*)three/s', $row['file'], $m);
