A solution without references and no implicit key names.

foreach ($array as $key => $innerArray) {
    foreach ($innerArray as $innerKey => $value) {
        if (false !== strpos($value, ' = ')) {
            unset($array[$key][$innerKey]);
            list($innerKey, $value) = explode(' = ', $value, 2);
            $array[$key][$innerKey] = $value;
        }
    }
}

foreach($array as &$title){
    $newTitle = array();
    $titleName = explode(' = ', $title[0] , 2);
    $newTitle['title'] = end($titleName);
    $titleNum = explode('-', $title[1] , 2);
    $newTitle[$titleNum[0]] = $titleNum[1];
    $titleContent = explode(' = ', $title[2] , 2);
    $newTitle['content'] = end($titleContent);  
    $title = $newTitle;
}

try this

foreach($array as $ky=>$val)  {
  echo $ky;
  var_dump(array_keys($val));
}

Why iterate? var_dump(array_keys($array)).

Joe Merra Over a year ago

i am try but i got 1-title1 2-title2 3-title3 4-title4

Robin Michael Poothurai Over a year ago

@Kenaniah because array_keys returns only parent key and if he wants to get title etc, he ca use array_keys

Kenaniah Over a year ago

@Robin, I get that, but your answer only references the keys. What you literally posted didn't use values at all.

@Robin, if I had a penny for every person I met who was as rude as you are, I'd probably have a penny.
