Hey all,
I have a problem with the following code i have written and was wondering if anyone can help?
The function below works fine if you define more than 2+ possible 'responses'. BUT, if theres only 1 'response' defined it wont work correctly. According to the PHP function 'array_rand($foo, number)', if no 'number' is set, the default is 1. So i have tried removing the value '2' in the function array_rand($myOutArray,2) but then the function wont work.
Any suggestions on what have i done wrong, i am sure i have overlooked something!
Thanks for any help. 
<?php
// Define the message,
$message = "Hello everyone!";
// Create an array of keywords that we want to search for in the message
$keyword=array(
"hello",
"hi",
"hey"
);
// Create an array of random responses
$response=array(
"Hey there!",
"Hello!",
"Hi!"
);
// This is the function which searches the message for any keywords and displays a random
// response if any keyword is found in the message (does nothing if no matches found, which is ok).
function checkForWord($myFindArray, $myOutArray, $message){
foreach ($myFindArray as $val) {
$pos = strripos($message,$val);
if ($pos !== false) {
$random_keys = array_rand($myOutArray,2);
$result = $myOutArray[$random_keys[0]];
return $result;
}
}
}
// Calls the function,
echo checkForWord($keyword, $response, $message);
?>
