Description:
------------
Hi
Just try this
$tmp="flight&Hotel&Car";
if($tmp=="flight&Hotel&Car"){
echo "Hello vinod";
}else{
echo "Bye vinod";
}
to your surprise it will display "Bye vinod" where as it should have
displayed "Hello vinod".
Its really astonishing that nobody pointed this error in php.
Reproduce code:
---------------
$tmp="flight&Hotel&Car";
if($tmp=="flight&Hotel&Car"){
echo "Hello vinod";
}else{
echo "Bye vinod";
}
Expected result:
----------------
Hello vinod
Actual result:
--------------
Bye vinod
