Question

I am trying to get the value from the array based on the key.

I have

$array1{
 '0' =>'text1',
 '1' =>'text2',
 '2' =>'text3'
}


$array2{
 '0' =>'123',
 '1' =>'456',
 '2' =>'789'
}

 //$source could be text1,text2 or text3
 //I want to show 123, 456 or 789 based on the value passed in
       if(in_array($source, $array1)){
         $id=array_keys($array1,$source);
         echo $array2[$id];
       }

I got an error saying ‘illegal offset type‘ becasue of $array2[$id].

Are there anyways to fix this? Thanks a lot!

I think you need array_search. Try:

if($id = array_search($source, $array1))
     echo $array2[$id];
