If you're after just a simple search, you could use fgets to grab the line and strpos to search it.

PHP Code:


			
// line: {"one":8405219,"two":4552659,"three":6640965}

$search = '"three":6640965';



$fp = fopen('misc.txt', 'r');



$result = 'No result';

while( ! feof($fp))

{

    $line = fgets($fp, 70);

    if (strpos($line, $search) !== FALSE)

    {

        $result = trim($line);

        break;

    }

}

fclose($fp);



echo $result;

For me, searching through a 46MB file with lines like yours took under two seconds to not find a match (worst case scenario).
