copied!<p>I'd say, try to <a href="http://php.net/unserialize" rel="noreferrer"><code>unserialize</code></a> it ;-)</p> <p>Quoting the manual :</p> <blockquote> <p>In case the passed string is not unserializeable, FALSE is returned and E_NOTICE is issued.</p> </blockquote> <p>So, you have to check if the return value is <code>false</code> or not <em>(with <code>===</code> or <code>!==</code>, to be sure not to have any problem with <code>0</code> or <code>null</code> or anything that equals to <code>false</code>, I'd say)</em>.</p> <p>Just beware the notice : you might want/need to use the <a href="http://www.php.net/manual/en/language.operators.errorcontrol.php" rel="noreferrer">@ operator</a>.</p> <p>For instance :</p> <pre><code>$str = 'hjkl'; $data = @unserialize($str); if ($data !== false) { echo "ok"; } else { echo "not ok"; } </code></pre> <p>Will get you :</p> <pre><code>not ok </code></pre> <p><br> EDIT : Oh, and like @Peter said (thanks to him!), you might run into trouble if you are trying to unserialize the representation of a boolean false :-(</p> <p>So, checking that your serialized string is not equal to "<code>b:0;</code>" might be helpful too ; something like this should do the trick, I suppose :</p> <pre><code>$data = @unserialize($str); if ($str === 'b:0;' || $data !== false) { echo "ok"; } else { echo "not ok"; } </code></pre> <p>testing that special case before trying to unserialize would be an optimization -- but probably not that usefull, if you don't often have a false serialized value.</p>
