Will strtok(null) cause any bugs?
<p>PHP script to read in user action requests and parse them to their components. Example, user types in <code>SET Colour = Blue</code> or <code>describe Chocolate Cake = The best cake ever!</code> I'm using like this:</p>

<pre><code>$actionKeyword = strtok( $actionRequest, " " ); // keyword followed by space
$name = strtok( "=" ); // Then name followed by equals
$description = strtok(null); // get the rest of the string
</code></pre>

<p>I could not find anything on getting the rest of the string. PHP.net's example was using spaces to tokenize each word but there was no character I could think of that might not be part of the description. This solution works in my tests.</p>

<p>Is there a side effect or special case this would fail on? Or is this a perfectly safe and acceptable way of getting the rest of the line?</p>
