Hi, this is CI irrelevant, but i need ur help.

Im checking if $value exists in $Temp arary or not. The code as following:

Code:

$value = '123';    
        $Temp = array();
        if (!$Temp =[$value]) {
            $Temp =[$value] = '1';
        } else {
            echo $value.'exist in array';
