copied!<p>There are mainly two possible ways to achieve this:</p> <ol> <li><p>Serialize the data in some way:</p> <pre><code>$postvalue = serialize($array); // client side $array = unserialize($_POST['result']; //server side </code></pre> <p>And then you can unserialize the posted values with <code>unserialize($postvalue)</code> Further information on this is <a href="http://php.net/manual/en/function.serialize.php">here in the php manuals</a>.</p> <p>Alternativley you can use the <code>json_encode()</code> and <code>json_decode()</code> functions to get a json formatted serialized string. You could even shrink the transmitted data with <code>gzcompress()</code> (note that this is performance intensive) and secure the transmitted data with <code>base64_encode()</code> (to make your data survive in non-8bit clean transport layers) This could look like this:</p> <pre><code>$postvalue = base64_encode(json_encode($array)); //client side $array = json_decode(base64_decode($_POST['result'])); //server side </code></pre> <p>A not recommended way to serialize your data (but very cheap in performance) is to simply use <code>implode()</code> on your array to get a string with all values separated by some specified character. On serverside you can retrieve the array with <code>explode()</code> then. But note that you shouldn't use a character for separation that occurs in the array values (or then escape it) and that you cannot transmit the array keys with this method.</p></li> <li><p>Use the properties of special named input elements:</p> <pre><code>$postvalue = ""; foreach ($array as $v) { $postvalue .= '<input type="hidden" name="result[]" value="' .$v. '" />'; } </code></pre> <p>Like this you get your entire array in the <code>$_POST['result']</code> variable if the form is sent. Note that this doesn't transmit array keys. However you can achieve this by using <code>result[$key]</code> as name of each field.</p></li> </ol> <p>Every of this methods got their own advantages and disadvantages. What you use is mainly depending on how large your array will be, since you should try to send a minimal amount of data with all of this methods.</p> <p>An other way to achieve the same is to store the array in a server side session instead of transmitting it client side. Like this you can access the array over the <code>$_SESSION</code> variable and don't have to transmit anything over the form. For this have a look at <a href="http://ch.php.net/manual/en/session.examples.basic.php">a basic usage example of sessions on php.net</a></p>
