Body
What you are doing is a very bad idea But lets first answer the actual question you are asking. To be able to do that you will have to actually process the file first in some kind of data structure that allows for that to be done. I'd presonally recommend an array in the form of <code>IP => AMOUNT</code>. For example (untested code): <pre><code>$fd = file($file); $ip_list = array(); for ($fd as $line) { list($ip, $amount) = explode("-", $line); $ip_list[$ip] = $amount; } </code></pre> Note that the code is not perfect as it would leave a space at the end of <code>$ip</code> and another in front of <code>$amount</code> due to the nature of your original data. But it works good enough just to point you in the right direction. A more "accurate" solution would involve regular expressions or modifying the original data source to a more convenient format. <hr> Now the real answer to your actual problem Your process will quickly become a performance bottleneck as you would have to open up that file, process it and write it all back again afterwards (not sure if you can do in-line editing of an open file) for every request. As you are trying to do some kind of per-IP hit count, there are a lot of better solutions to your problem: <ul> <li>Use an existing solution for it (like <a href="http://piwik.org/" rel="nofollow">piwik</a>)</li> <li>Use an actual database for your data</li> <li>Keep your file simple with just a list of IPs and post-process it off-line periodically to make it be the format you want</li> <li>You can avoid writing that file altogether if you have access to your webserver's logs (and they are setup to log every request with the originating IP) and you can post-process that file instead</li> </ul>

1. COI thought it was a bad idea, but i didn't understand why. As everyone suggested, i've done it with a database instead. Thanks for your help.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
