Displaying only immediate children (only one level) pages using get_pages() function

Displaying only immediate children (only one level) pages in WordPress. For example, I have page and sub page structure like:

Page 1
  Page 11
     Page 111
     Page 112
  Page 12
  Page 13
Page 2
  Page 21
  Page 22
     Page 221
     Page 222

Let’s suppose, you need to list all children pages of Page 1, i.e. Page 11Page 12Page 13. But you don’t want to be listed Page 111Page 112 and so on which is WordPress’s default behavior.

Let us assume that ID of Page 1 is 5 then:

$result = get_pages('child_of=5&hierarchical=0&parent=5);

Notice the child_of and parent must have same value. This function will get only three page – Page 11Page 12Page 13 and not Page 111, Page 112 and so on.

by using extract() function, we can create variables with associative arrays elements

varaible names are element keys and variable values are element values

echo $x;  //10
echo $y;  //20
echo $abc;  //scott
