    copied!<p>Update: I found the cause. It was because the file only had carriage returns. After replacing them with CR+LF (<code>\r\n</code>), it works normally on the server.</p> <p>Original post: </p> <p>I just uploaded my site to my webhost and I noticed a strange issue regarding POST data. On localhost, everything works as it should, but on the server for some reason the POST data seems to vanish in the middle of processing?</p> <p>The site submits data from a form to guestbookFormProcessor.php:</p> <pre><code>&lt;!doctype html&gt; &lt;html lang="en"&gt; &lt;head&gt; &lt;title&gt;Add Guestbook Comment&lt;/title&gt; &lt;meta charset="UTF-8" /&gt; &lt;/head&gt; &lt;body&gt; &lt;?php var_dump($_POST); // This returns data OK on the server // Process POST data $unsafeFormData = array_values($_POST); var_dump($unsafeFormData); // This returns nothing on the server! // anything after this point will not appear on the page, not even echos ?&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>But that outputs nothing at all on the server! </p> <p>If I add an <code>echo 'Test';</code>, it appears on the page, but if I add it <em>after</em> the <code>$unsafeFormData = array_values($_POST);</code> then it does <strong>not</strong> appear?!</p> <p>In fact, anything I add after that row, does not appear on the page. I also checked for any strange characters in the row, but it looks normal even to a hex editor. What could be wrong? It seems to be related to the array_values() function since this happens:</p> <p><code>var_dump($_POST);</code><br> array(5) { ["name"]=> string(4) "Juha" ["antispam"]=> string(1) "4" ["antispamIndex"]=> string(1) "1" ["message"]=> string(4) "Test" ["submit"]=> string(4) "Send" } </p> <p><code>var_dump($unsafeFormData);</code><br> (no output at all!)</p> <p>Why would the POST data disappear after array_values()?</p> <p>Thanks!</p>
