undefined function codeigniter

When I call the search_array function, I get this error:

Call to undefined function search_array()

Even if I make all the function public, it doesn't work. How is this possible? 

 function search_array($needle, $haystack) {
     if(in_array($needle, $haystack)) {
          return true;
     }
     foreach($haystack as $element) {
          if(is_array($element) && search_array($needle, $element))
               return true;
     }
   return false;
}

public function do(){
   $excist = $this->search_array($test[2], $allValuta);
}

Modify your codes to be like this:

function search_array($needle, $haystack) {
     if(in_array($needle, $haystack)) {
          return true;
     }
     foreach($haystack as $element) {
          if(is_array($element) && $this->search_array($needle, $element))
               return true;
     }
   return false;
}

public function do(){
   $excist = $this->search_array($test[2], $allValuta);
}

Tell me if it works.

In codeigniter, to call a function you should use $this->. So add $this-> to search_array()

Like this,

if(is_array($element) && search_array($needle, $element))

to

f(is_array($element) && $this->search_array($needle, $element))
                        ^     ^

Are you in a class ? If not, you are defining a function search_array(). So you should not call it with **$this->**search_array(...), this scheme is the use for a method of a class.

In short : remove the $this->
