I have a question about using if statements with variables that are
sometimes arrays and sometimes not arrays.
I have a function that returns either the contents of a database row or
false.
For example:
$variable = callfunction()
In this case, callfunction would either return the contents of a row in
a database or simply false.
Lets assume that, for instances of this question, callfunction returns
false and $variable is now equal to false.
function callfunction()
{
return false;
}
If I then use:
if ($variable['alias'])
Will the if statement result in false because that is the only value of
$variable (noting that $variable has NOT been initiated as an array,
this is the first time it has been refrenced as an array)?
