Answer 1

Just use like this :

foreach($fname as $name){
       $n=$name;
     }

Edit :

$fname=$this->input->post('first_name');
for($i=0;$i<count($fname);$i++) {
    echo $fname[$i];
}

Answer 2

change foreach like this

   foreach($fname as $name){
   $n=$name; //return only first character
 }

this working fine

OR You store all data (first_name) single cell try this

example: sample1,sample2

 $first_names= implode(",",$fname); 

Answer 3

You can use it like this:

foreach($this->input->post("first_name") as $name){
    $n=$name;
}

No need to assign post data to a variable.
