using "&" in variables

[digitalecartoons]

Im using this line to send variables to Flash:

 echo "&myVar=$myVar&"; 

Just because I noticed that on some php servers this doesn't work:

echo "myVar=$myVar"; 

But again, on some it does work.

What's the purpose of putting "&" characters in front and after the variable declarations? And what php server setting wants them to be there and which doesn't?

your adding the "&" to the string so basically it should make little or no difference maybe its building a query string then it could make a difference however would like to see your code
