I think this is as close as you can get:
As you want the line count per file, you need to read every file entirely; I don't see much chance to improve on speed...

substr_count
SUBSTR_COUNT(3) 1 SUBSTR_COUNT(3)substr_count - Count the number of substring occurrencesSYNOPSIS
int substr_count (string $haystack, string $needle, [int $offset], [int $length])
DESCRIPTION substr_count(3) returns the number of times the $needle substring occurs in the $haystack string. Please note that $needle is case sensi-
tive.
Note
This function doesn't count overlapped substrings. See the example below!
PARAMETERS
o $haystack
- The string to search in
o $needle
- The substring to search for
o $offset
- The offset where to start counting
o $length
- The maximum length after the specified offset to search for the substring. It outputs a warning if the offset plus the length is
greater than the $haystack length.
RETURN VALUES
This function returns an integer.

EXAMPLES
Example #1
A substr_count(3) example
<?php
$text = 'This is a test';
echo strlen($text); // 14
echo substr_count($text, 'is'); // 2
// the string is reduced to 's is a test', so it prints 1
echo substr_count($text, 'is', 3);
// the text is reduced to 's i', so it prints 0
echo substr_count($text, 'is', 3, 3);
// generates a warning because 5+10 > 14
echo substr_count($text, 'is', 5, 10);
// prints only 1, because it doesn't count overlapped substrings
$text2 = 'gcdgcdgcd';
echo substr_count($text2, 'gcdgcd');
?>
