When using a random number it returns a decimal. Does using it as an array index automagically int() it?
Take a look at the scalar we're creating:
$myarray[rand(@myarray)];
You'll notice that
rand is being passed
@myarray. Since rand is expecting a scalar,
@myarray is interpreted in a scalar context. Therefore, it returns the length of the array (52 in this case), which will cause rand to generate a random number from 0 to 51, which fits the array index quite nicely. Perhaps this would have been more clear:
$myarray[rand($#myarray)];
Cheers,
Ovid
