PHP: %-sign in string?
<p>I have gotten a PHP script which uses an array to store configuration data, like <code>$config["maxPosts"] = 5;</code>.<br>
Some of the settings need to be given as a string. In an example file, that looks like this:</p>

<pre><code>$config["welcomeMsg"] = "Welcome home, %name%";
</code></pre>

<p>What does the <code>%</code> mean in that case?</p>
