    <p>I have sort of a "beginning" of a solution. I wrote this function (Sorry about the spacings):</p> <pre><code>&lt;?php set_time_limit(0); // Just to get the remote filesize function checkFilesize($url, $user = "", $pw = ""){ ob_start(); $ch = curl_init($url); curl_setopt($ch, CURLOPT_HEADER, 1); curl_setopt($ch, CURLOPT_NOBODY, 1); if(!empty($user) &amp;&amp; !empty($pw)){ $headers = array('Authorization: Basic ' . base64_encode("$user:$pw")); curl_setopt($ch, CURLOPT_HTTPHEADER, $headers); } $ok = curl_exec($ch); curl_close($ch); $head = ob_get_contents(); ob_end_clean(); $regex = '/Content-Length:\s([0-9].+?)\s/'; $count = preg_match($regex, $head, $matches); return isset($matches[1]) ? $matches[1] : "unknown"; } // Split filesize to threads function fileCutter($filesize,$threads){ $calc = round($filesize / count($threads)); $count = 0; foreach($threads as $thread){ $rounds[$count] = $calc; $count++; } $count = 0; foreach($rounds as $round){ $set = $count + 1; if($count == 0){ $from = 0; } else { $from = ($round * $count); } $cal = ($round * $set); $final[$count] = array('from'=&gt;$from,'to'=&gt;$cal); $count++; } // Correct the "Rounded" result $end = end($final); $differance = $filesize - $end['to']; if (strpos($differance,'-') !== false) {} else {$add = '+';} $end_result = ($end['to'].$add.$differance); $value=eval("return ($end_result);"); $end_id = end(array_keys($final)); $final[$end_id]['to'] = $value; // Return the complete array with the corrected result return $final; } $threads = array( 0=&gt;'test', 1=&gt;'test', 2=&gt;'test', 3=&gt;'test', 4=&gt;'test', 5=&gt;'test', ); $file = 'http://www.example.com/file.zip'; $filesize = checkFilesize($file); $cuts = fileCutter($filesize,$threads); print_r($cuts); ?&gt; </code></pre> <p>(Again, Sorry. :) )</p> <p>It gives "directions" to split the file in specific bytes. I've tried to do something like so:</p> <pre><code>foreach($cuts as $cut){ $start = $cut['from']; $finish = $cut['to']; $f = fopen($file, "rb"); fseek($f, $start, SEEK_SET); while(!(ftell($f) &gt; $finish)){ $data = fgetc($f); } fclose($f); </code></pre> <p>But it's going to a endless loop. What is the problem? or, is there another solution in PHP to split and combine files?</p>

    1. COLook at http://stackoverflow.com/a/12407208/1226894 it can split by line or size ... you should also look at http://stackoverflow.com/a/10271542/1226894

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.
