Interpreting the practical application of PHP recursive Array

We arePHP recursive array code:

 
 

  
  
<?Php
  
  
Ignore_user_abort (); // after the connection is interrupted (for example, the browser is closed), the following script continues to be executed until the processing is completed.
  
  
Set_time_limit (0 );
  
  
$Get_data=File_get_contents("Php: // input ");
  
  
$ExplodeExplodeexplodedata= Explode ("&", $ get_data );
  
  
Foreach ($ explodedata as $Key=>$ Value) // restore the Array
  
  
{
  
  
List ($ realkey, $ realvalue) = explode ("=", $ value );
  
  
$ Data [urldecode ($ realkey)] = urldecode ($ realvalue );
  
  
}
  
  
// Now the $ data array is the same as that in a. php. Next, you can operate the $ data array as needed.
  
  
//......
  
  
?>
 
 

The code above is the detailed code of PHP recursive array. I don't know if it helps beginners of PHP.
