    <p>My script puts together a set of htaccess rules based on information passed into it and gives the user a downloadable text file with the rules printed out inside. The idea is that an administrator fills out some form information, clicks a downloadable link, gets a text file with the rules printed out inside, opens the file, copies the rules and pastes them into the htaccess file of their domain.</p> <p>I've managed to put together the script that produces these rules. However, the text file seems to ignore all newline characters that I print to it. The tabs work, but the newlines do not. It must have something to do with the encoding I'm using with the header() function calls, but I'm not sure what I'm doing wrong. No amount of Googling as seemed to point me in the right direction. Any input would be appreciated.</p> <p>Here's the code:</p> <pre><code>header('Content-Type: application/octet-stream'); header('Content-Disposition: attachment; filename="htaccess.txt"'); header('Content-Transfer-Encoding: binary'); $id = addslashes( $_GET['id']); $location = addslashes( $_GET['location'] ); $location = substr($location, strpos($location, '/', 9 ) + 1 ) . ( ( substr( $location, strlen($location) - 1 ) == '/' ) ? '' : '/' ); $regEx = '([0-9a-zA-Z-_]*)'; $lines = array(); for( $x = 0; $x &lt; 10; $x++ ) { $line = 'RewriteRule ^' . $location; for( $y = 1; $y &lt;= $x; $y++ ) $line .= $regEx . '/'; $line .= '*$' . "\t\t\t\t\t"; $line .= "http://localhost/redirect.php?ring=$id"; $line .= ( $x &gt;= 1 ) ? '&amp;link=$1' : ''; $line .= ( $x &gt; 1 ) ? '&amp;tag' . ( $x - 1 ) . '=$' . $x . ' [NC]' . "\n" : "\n"; $lines[] = $line; } foreach( $lines as $line ) echo $line; </code></pre>

    1. COI tried "\n" and "\r\n" and I got the same result. I'm testing it on a windows machine. However, I'm using XAMPP to run a virtual Apache server on my computer to do my testing. The server it will eventually be hosted on is Linux. Maybe I'll try uploading it there and see what I get.

    2. COOk... thats strange. During my testing, I was opening the text file in Notepad and getting the same exact result. I tried opening it in Wordpad and it works.... weirdly. I tried the "\n\r" combination and it still doesn't work in notepad, but it double spaced now in Wordpad. I tried Mike B's idea of using PHP_EOL, but that didn't seem to change anything. I thought maybe I was getting a cached version, so I cleared my browser cache and added some Cache control headers, but it wasn't until I re-entered the URL did I start seeing changes I made..... weeeeird.

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.
