Why am I getting a syntax error?
<p>Why is this php statement <code>$var1 += &amp; $var2</code> wrong?<br>
<strong>response to comments</strong>: i'm using it to store a smart database query, in fact $var2 is my database connection, i can't drop the reference because it would mean making too many copies of my database, as for the bitwise response <code>&amp;=</code> will do the increment also?</p>
