PHP Question
I have program written by someone whom I'm not able to contact. I'm needing to revise this script and I've run into an operator(??) I've never seen before and can't find a reference to it. Here's the snippet of code in question:
$MainContents =& ob_get_contents();
What does the =& mean?
Thanks. Any insights you can provide would be appreciated.

Welcome to TWF, Dami.
That's a reference. I've not used them, so all I can do is point you to the PHP Docs:

Well, I can see that's way beyond my meager abilities.
Thanks for the link, Mark. I'd searched there, but obviously not in the right area.

'&' is the bitwise AND operator, bits in both operands are set. any operator trailing a '=' such as +=, *=, %= etc will the left value the result of the operation between left and right value. for instance $a=5; $a*=10; // result is $a = 500.

i now see that it's =& not &=, doh on me.
$MainContents =& ob_get_contents();
assigns a reference to ob_get_contents in $MainContents

Howard, isn't the amp on the wrong side?

Thanks, guys, for the information. Sorry to take so long to acknowledge your comments. 99% of what you said was so over my head. I'll back up and bit and start with smaller steps.
