How to parse this complex array in PHP?

Question

I have this structure coming from an array dump:

0 => 
object(stdClass)[3]
  public 'start' => string '12:30:00' (length=8)
  public 'end' => string '12:45:00' (length=8)
  public 'structure' => 
    object(stdClass)[5]
      public 'structure_id' => int 5
      public 'structure_name' => string 'LABORATORY 1' (length=18)
  public 'specialist' => 
    object(stdClass)[6]
      public 'specialist_id' => int 222
      public 'specialist_surname' => string 'Smith' (length=7)
      public 'specialist_name' => string 'John' (length=9)
      public 'specialist_signature' => string 'Dr.' (length=3)
  public 'price' => float 80.5
1 => 
object(stdClass)[3]
  public 'start' => string '12:30:00' (length=8)
  public 'end' => string '12:45:00' (length=8)
  public 'structure' => 
    object(stdClass)[5]
      public 'structure_id' => int 5
      public 'structure_name' => string 'LABORATORY 4' (length=18)
  public 'specialist' => 
    object(stdClass)[6]
      public 'specialist_id' => int 222
      public 'specialist_surname' => string 'White' (length=7)
      public 'specialist_name' => string 'Jack' (length=9)
      public 'specialist_signature' => string 'Dr.' (length=3)
  public 'price' => float 80.5
2 => 
object(stdClass)[3]
  public 'start' => string '12:30:00' (length=8)
  public 'end' => string '12:45:00' (length=8)
  public 'structure' => 
    object(stdClass)[5]
      public 'structure_id' => int 5
      public 'structure_name' => string 'LABORATORY 9' (length=18)
  public 'specialist' => 
    object(stdClass)[6]
      public 'specialist_id' => int 222
      public 'specialist_surname' => string 'Brown' (length=7)
      public 'specialist_name' => string 'Lester' (length=9)
      public 'specialist_signature' => string 'Dr.' (length=3)
  public 'price' => float 80.5

How to parse it with PHP? In particular, I would like to assign values to normal PHP variables in order to print them or to put into an HTML table.

Why go through all the overhead of assigning values from this array of objects to variables; just access them as they are when you need them — Mark Baker

You can access this structure like this

echo $object[0]->start;
echo $object[0]->end;
echo $object[0]->structure->specialist_id;

This will result

12:30:00
12:45:00
5

Why do you need variables for this? That will result in too many vars. Instead use a loop to iterate over the object and access the inner objects using "->"

Great,Jabran!!! :-) I define $object by passing to this variable the object coming from the array (which is actually a JSONed array). So I've solved this way: $object = json_decode($response->result); $response->result comes from a CURL call, which queries a web service and get 'result' in return. Again, thank you!!! :-)

You need to make use of the extract() on PHP

<?php
$size = "large";
$var_array = array("color" => "blue",
                   "size"  => "medium",
                   "shape" => "sphere");
extract($var_array, EXTR_PREFIX_SAME, "wddx");
echo "$color, $size, $shape, $wddx_size\n";
?>

OUTPUT :blue, large, sphere, medium
