Hi @ all:
Question: what is quickly?
if( true == isset( $var ) ){}
or
if( isset( $var ) ){}
Can somebody explain ( not think or believe ), what happend on the Zend
Engine when the first or the second code will be use?
Regards
Carlos
The _exact_ same thing happens.
#1 (with the == true) results in an extra opcode compared to the other,
thus making it a very very very tiny bit "slower". But other than that,
there is _no_ difference _at all_. And trust me, you won't see _any_
difference in execution time by changing the first into the other, it's
so infintissimally tiny.
