    <p>I've got a program that takes 3 arrays (which are the same length, can contain 500 items or so) and writes them to a text file.</p> <p>However I'm getting an issue with writing larger files. The arrays are coordinates and timestamps of a canvas drawing app so I can control the length. I've found that once files start getting larger than 2mb it doesn't save the file. The maximum file I've managed to save has been 2.18mb. From a related question <a href="https://stackoverflow.com/questions/3325917/php-having-trouble-uploading-large-files">PHP: Having trouble uploading large files</a> I've determined that the cause is most likely due to having this hosted on a free hosting server. I've looked at phpinfo() and here are the 4 relevant numbers:</p> <pre><code>memory_limit 16M max_execution_time 30 upload_max_filesize 5M post_max_size 5M </code></pre> <p>Here is the relevant writing code: </p> <pre><code>// retrieve data from the JS $x_s = $_GET['x_coords']; $y_s = $_GET['y_coords']; $new_line = $_GET['new_lines']; $times = $_GET['time_stamps']; print_r($_GET); $randInt = rand(1,1000); // first want to open a file $file_name = "test_logs/data_test_" . $randInt . ".txt"; $file_handler = fopen($file_name, 'w') or die("Couldn't connect"); // For loop to write the data for ($i = 0; $i &lt; count($x_s); $i++){ // If new line want to write new line! if (!$new_line[$i]){ if ($i!=0){ // If not the first line fwrite($file_handler, "LINE_END\n"); } fwrite($file_handler, "LINE_START\n"); } // Write the x coord, y coord, timestamp fwrite($file_handler, $x_s[$i] . ", ". $y_s[$i] .", ". $times[$i]. "\n"); // If last line then write last LINE_END if ($i == (count($x_s)-1)){ fwrite($file_handler, "LINE_END\n"); } } fclose($file_handler); </code></pre> <p>I've setup a php server on my localhost and have access to the error log. This is what I am getting.</p> <pre><code>[Fri Mar 23 20:03:02 2012] [error] [client ::1] request failed: URI too long (longer than 8190) </code></pre> <p>PROBLEM RESOLVED: The issue was that I was using GET to send large amounts of data, which was appended to the URI. Once the URI reached 8190 characters it had an error. Using POST solves this.</p>

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.
