The title is in the question (EDIT: 😛 I mean the question is in the title), basically can I call variable $x before defining it further down the page?

I am not quite sure to understand your point but if you want to write
you will not get “2” as a result.
PHP will usually not issue a warning when you reference a variable that has not yet been assigned a value. PHP will create it on the fly and assign it the null value which will then be casted to whatever scope you have. For example
will print 5 because in this case $b will be interpreted as beeing 0.
I hope this will help
