How about:

count(preg_grep("/118\-bonsplans\.com/", file("acct-2012-08-24-0001.csv")));

The first argument to preg_grep is a regular expression pattern. The second is an array to search through. It returns an array of the items in the searched array that matched.

You can try with the following code:

$handle = fopen('acct-2012-08-24-0001.csv', 'r');
$counter = 0;
if ($handle) {
while (($buffer = fgets($handle, 4096)) !== false) {
    if (stristr($buffer, '118-bonsplans.com')) $counter += 1;
}
fclose($handle);
}
echo $counter;
