Any equivalent to .= for adding to beginning of string in PHP?
<p>Just wondering if there is something like .= for adding text to the beginning of a string, e.g.:</p>

<pre><code>$foo =. $bar;
</code></pre>

<p>which doesn't work.</p>

<p>Edit - sorry for the stupidity... the example should be:</p>

<pre><code>$foo =. 'bar';
</code></pre>

<p>(which also doesn't work, but I wish did).</p>
