Answer 1

Let's do this with Recursive:
public function array_print(){
$myArray = array(
'type'=>'Array outside 1',
'name'=>'Array outside 2',
array(
'file_name'=>'second array',
array(
'file_ext'=>'third array',
array('text'=>'Fourth array inside thrid array')
)
)
);
Print "<pre>";
$output=array();
$result=$this->recursive($myArray);
print_r($result);
//Output value has key and value. I used ## as separator
foreach ($result as $value) {
$data = explode('##',$value);
$output[$data[0]] = $data[1];
}
print_r($output);
}
function recursive($array){
global $temp_data;
if(!empty($array)){
foreach($array as $key => $value){
//If $value is an array.
if(is_array($value)){
//We need to loop through it.
return $this->recursive($value);
} else{
$temp_data[]= $key.'##'.$value;
}
}
}
return $temp_data;
}
Using this we can loop through multidimensional array and store it in Global array. $myArray is your array.
