Removing a space
<p>I have a variable</p>

<pre><code>$abc='akr:/9888/fk4f76mhn';
</code></pre>

<p>Another variable</p>

<pre><code>$url =  'http://alpha.com/zidd/id/'.$abc; 
</code></pre>

<p>Which is giving me</p>

<pre><code>http://alpha.com/zidd/id/ akr:/9888/fk4f76mhn 
</code></pre>

<p>A space is being introduced between <code>id/</code> and <code>akr:/9888/fk4f76mhn</code> which I do not want.</p>

<p>Is there anything wrong I am doing here?</p>
