Question

I created a function that should in theory create an array from another array (basically what i want to do its bring it down 1 level).

My problem is that somehow the code creates another array inside the new array when it shouldn’t…. and even more the output is rather strange.
The final array should all be in the same level but somehow it creates it multidimensional and with extra values.

The problem seems to be in the loop, but i can’t see where

any help is appreciated.

    public function pullCompetencyByCID ( $cID ) {
                    $sql = 'SELECT * FROM ldc_competency_'.$this->lang.' WHERE cID='.$cID;
                    $result = $this->db->query($sql)->fetchAll(PDO::FETCH_ASSOC);                   
                         foreach ( $result as $key2 => $val2 ){
                                switch ($key2){
                                    case 'cName':       $cName = $val2;         
                                                        break;
                                    case 'cID':         $cID = $val2;
                                                        break;
                                    case 'cLevel':      $cLevel = $val2;
                                                        break;
                                    case 'cDetails':    $cDetails = $val2;
                                                        break;
                                    case 'cSummary':    $cSummary = $val2;
                                                        break;
                                }
                        }
                    $pullCompetency = array('cName'=>$cName,'cID'=>$cID, 'cLevel'=>$cLevel, 'cDetails'=>$cDetails, 'cSummary'=>$cSummary);          

                    return $pullCompetency;
    }

The output of that code is

 Array ( 
    [cName] => Array ( 
                        [cID] => 2 
                        [cName] => dos
                        [cLevel] => 2
                        [cDetails] => doss
                        [cSummary] => dosssss 
                         ) 
    [cID] => 2
    [cLevel] => 
    [cDetails] => 
    [cSummary] => 
)

The output of just the $result is

Array ( 
    [0] => Array ( 
                    cID] => 2 
                    [cName] => dos 
                    [cLevel] => 2 
                    [cDetails] => doss 
                    [cSummary] => dosssss
                     )
     )

to avoid confusion the desired result should be

 Array ( 
        [cID] => 2 
        [cName] => dos 
        [cLevel] => 2 
        [cDetails] => doss 
        [cSummary] => dosssss
         )

Since you’re doing ->fetchAll(), $result is going to be a 2-D array of results:

foreach ( $result as $key2 => $val2 ){
                      ^-- row number
                               ^--- array row contents

you then stuff that sub-array into your new array, causing your sub-arrays.
