Random String

[brmcdani]

Iam tring to pull a random string out of an array.  I have it working but it output's 2 strings and I just want it to output 1.  I have tried changing the code up from $keys = array_rand($rand, 2); to $keys = array_rand($rand, 1); but it still won't work.  Here is my complete code snippet:

 

$rand = array("asfd", "ghdg", "kfdr", "sdas", "hdsa", "gdsd", "ijko");

$keys = array_rand($rand, 2);

echo "Verification letters:  ";

echo $rand[$keys[0]] . "\n";

echo $rand[$keys[1]] . "\n";

From the manual:

If you are picking only one entry, array_rand()  returns the key for a random entry. Otherwise, it returns an array of keys for the random entries.

 

Did you take that into account when switching from 2 to 1?

Yeah it says it can "take 1 or more random entries out of an array"

 

I just do not understand why it won't take 1 when I enter in 1

You didn't listen to what he said. When grabbing only 1 random key it doesn't return an array. So $keys[0] and $keys[1] are non-existent. If you were only doing one you'd have to do: echo $rand[$keys];

You could always force it to be an array: $keys = (array) array_rand($rand, 1);
