Hi friends.
I have a little confusion when reading a php book.
In one of the first chapters, it teaches me about 'operator precedence'.
Here is the extract from the book:
Here ’ s a list of all the operators you ’ ve encountered so far, in order of precedence (highest first):
Precedence of Some PHP Operators (Highest First)
++ - - (increment/decrement)
(int) (float) (string) (array) (object) (bool) (casting)
! (not)
/ % (arithmetic)
+ - . (arithmetic)
< < = > > = < > (comparison)
== != === !== (comparison)
& & (and)
|| (or)
= += - = = /= .= %= (assignment)
and
xor
or
......... the problem i am having is that I do not understand why (what appears to be) the concatenation operator is classed as an arithmetic operator?
I really don't get it. Can someone explain?
Paul.
