Assignment Operators

   
Operator     Example         Meaning
=            $var = 5;       Assign 5 to $var
+=           $var += 3;      Add
-=           $var -= 2;      Subtract
.=           $str.="ing";    Concatenate ing to $str
*=           $var *= 2;      Multiply $var by 2
/=           $var /= 2;      Divide $var by 2
**=          $var **= 2;     Square $var
%=           $var %= 2;      Divide $var by 2
x=           $str x= 2;      Repeat value of $str 2 times
<<=          $var <<= 1;     Left-shift bits in $var one position
>>=          $var>>= 2;      Right-shift bits in $var two positions
&=           $var &= 1;      One is bitwise-ANDed to $var
|=           $var |= 2;      Two is bitwise-ORed to $var
^=           $var ^= 2;      Two is bitwise-exclusive ORed to $var
