1D -> 2D String array conversion


Yes, it's possible. For example (you'd have to tailor it depending on the exact result you want to achieve)

public static String[][] convertTo2D(
String[] arr, int x, int y ) {
  //if ( arr.length != x * y ) throw new
IllegalArgumentException();
  String[][] ret = new String[x][y];
  for( int i_x = 0, i = 0; i_x < x; i_x++ )
    for( int i_y = 0; i_y < y; i_y++, i++ ) {
      //if ( i >= arr.length ) return ret;
      ret[i_x][i_y] = arr[i];
    }
  return ret;
}

This should help you get started. The var_dump is basicly for debugging showing you the contents of the variable. foreach($data as $foo) { if(is_array($foo) { foreach($foo as $bar) { var_dump($bar); } } else { var_dump($foo); } } Consider that this could also be solved in a recursive fashion. function printNestedArray($foo) { if(is_array($foo) === false) {

Notice: Array to string conversion when using Foreach
I think the cause of the error is in line 3 and 4 of the first code block you posted: $this->errors[] = array(); $this->succes[] = array(); Try changing those lines into: $this->errors = array(); $this->succes = array(); In your code you create an array and immediately set the first element of the array to be an array. You can see that in the var_dump you posted: array(2) { [0]=

Looks like in the $custom_image just the path to the image is required but you are assigning the whole $_FILES[] compound array to it. Try replacing this line $custom_image=$_FILES['custom_image']; in your code with this, $custom_image=$_FILES['custom_image']['tmp_name']; and see if it works
