php inverted comma in a variable
<p>I am trying to assign a string to a variable like that</p>

<p><code>$start "&lt;?xml version="1.0" encoding="utf-8"?&gt;"</code></p>

<p>Its giving me error
PHP Parse error:  syntax error, unexpected T_DNUMBER</p>

<p>I think its because I am inserting " between and also ? 
How to solve this ?</p>
