Instead of foreach loop, how can I use in_array()?

Question

In codeigniter, in my controller file, I fetch data from model. To validate the results I use foreach loop and there is no problem. But instead of using foreach I want to use in_array() to control if variable is in database result array or not . Here is code :

function _remap($method,$params = array()){ 

//in construct, I use $this->model
if (isset($params[0])) {

    $this->db->distinct('*****');
    $this->db->from('*****');
    $this->db->where('****',****);

    $query = $this->db->get();

    if (in_array($params[0],$query->results())) {
        echo "in_array works";
    }
}

But not echoing anything. How can I do it?Thanks.

It returns query result as an array of objects. Use result_array() to return a pure array and then try using in_array — verisimilitude

According to the manual you could use result_array(). Otherwise you will get back an object. Of course you cannot use in_array for an object.

Also according to the manual you could change your code to

if (in_array($params[0], $query->first_row('array')) {
  // ...

I wonder why this was downvoted? Anyways, I wonder the parameter isn't just put the in query?

Yeah, I am wondering too. But you could help and make justice :)! I have no idea about codeigniter, I just used my general programming senses (and Google)

The in_array is just to be used for only checking a value in the value-list
e.g. array("Mac", "NT", "Irix", "Linux");

in_array wont work for your situation, because it returns object array.

I would suggest to write a helper method, that does the job you want and returns True or False. Information on how to do it can be found here
