what does the operand += mean?

does it mean the value on the right should be added to to the value on the left and the left variable changes to the sum of the 2?

a friend just asked me and i don't even know.

a += b;

is the same as:

a = a + b;

Code:

a += b

is exactly equal to

Code:

a = a + b

any other blatently obvious code shortcuts for a n00b?

i can see where there might be a need for a "geral programming" tutorial category now.

here's different types of operators from the PHP manual:

Code:

a-- // a - 1
a++ // a + 1
a @= b // a @ b where @ is one of: -,+,/,*,<<,>>,>>>,|,&,^,%
--a // a - 1 prefix
++a // a + 1 prefix
