     between 5 and 15 (inclusive), for example, use <TT

    </P

>&#13;     In older versions of PHP, you had to seed the random number generator
     before use with <A

CLASS="function"
>srand()</B
></A
>. Since 4.2.0 this is no
     longer necessary.

>Note: </B

      In versions before 3.0.7 the meaning of
      <TT
CLASS="parameter"
><I
>max</I
></TT
> was <TT
CLASS="parameter"
><I
>range</I
></TT
>. To
      get the same results in these versions the short example should
      be <TT
CLASS="literal"
>rand (5, 11)</TT
> to get a random number
      between 5 and 15.
