PHP SplHeap isCorrupted() Function

  • Last Updated : 23 Mar, 2021

The SplHeap::isCorrupted() function is an inbuilt function in PHP which is used to tell if the heap is in a corrupted state.

Generally, the Heap Data Structure are of two types:

  • Max-Heap: In a Max-Heap the key present at the root node must be greatest among the keys present at all of its children. The same property must be recursively true for all sub-trees in that Binary Tree.
  • Min-Heap: In a Min-Heap the key present at the root node must be minimum among the keys present at all of its children. The same property must be recursively true for all sub-trees in that Binary Tree.

Syntax:

bool SplHeap::isCorrupted()

Parameters: This function does not accept any parameter.

Return Value: This function returns true if the heap is corrupted, false otherwise.



Below programs illustrate the SplHeap::isCorrupted() function in PHP:

Example 1:

PHP




<?php 
  
// Create a new empty Mix Heap 
$heap = new SplMinHeap(); 
  
// Insert elements in min heap
$heap->insert('System'); 
$heap->insert('GFG'); 
$heap->insert('ALGO'); 
$heap->insert('C');
$heap->insert('Geeks'); 
$heap->insert('GeeksforGeeks'); 
  
// Check heap is in a corrupted
// state or not
var_dump($heap->isCorrupted());
  
?>

Output:

bool(false)

Example 2:

PHP




<?php 
  
// Create a new empty Max Heap 
$heap = new SplMaxHeap(); 
  
// Insert elements in max heap
$heap->insert('System'); 
$heap->insert('GFG'); 
$heap->insert('ALGO'); 
$heap->insert('C');
$heap->insert('Geeks'); 
$heap->insert('GeeksforGeeks'); 
  
// Check heap is in a corrupted
// state or not
var_dump($heap->isCorrupted());
  
?>

Output:

bool(false)
