A simple way to randomly choose between from two strings

[etrader]

I need a simple code like

$test1="1";
$test2="2";
$test=$test1|$test2;
echo $test;

to randomly catch the value of strings $test1 or $test2; as each time running the code, echo shows randomly one of the strings.

 

Could you please guide what the third line should be ?

Here's one way to do it, put the strings in an array:

$strings = array("1", "2", "3", "4");
$test = $strings[rand(0, count($strings)-1)];

oh thanks, I did not think of the powerfulness of array

Thanks again!
