Late to the game but I needed this functionality today and I realized that @Javier's and @iguito's answers could be combined into a simple solution. I also replaced the check for \n with PHP_EOL for my use case:

// Get your matches
preg_match_all( '[YOUR REGEX HERE]', $data, $matches, PREG_OFFSET_CAPTURE );

// This is my loop format, yours may need to be different
foreach ( $matches[0] as $match ) {

    // Get the line number for the current match 
    list( $before ) = str_split( $data, $match[1] );
    $line_number = substr_count( $before, PHP_EOL ) + 1;
    echo $line_number;

}
