The DOMNode::isSameNode() function is an inbuilt function in PHP which indicates if two nodes are the same node or not.
Syntax:
bool DOMNode::isSameNode( DOMNode $node )
Parameters: This function accepts a single parameter $node which holds the node to be compared.
Return Value: This function returns TRUE on success or FALSE on failure.
Below given programs illustrate the DOMNode::isSameNode() function in PHP:
Program 1:
<?php // Create a new DOMDocument $dom = new DOMDocument();
// Create a paragraph element with a namespace $p_element = $dom ->createElementNS(
'my_namespace' , 'p' , 'GeeksforGeeks' );
// Append the child to DOMDocument $dom ->appendChild( $p_element );
// Check if the node is same $isSameNode = $dom ->isSameNode( $dom );
// Check if the namespace is default or not if ( $isSameNode ) {
echo 'Yes, $dom is same to itself.' ;
} ?> |
Output:
Yes, $dom is same to itself.
Program 2:
<?php // Create a new DOMDocument $dom = new DOMDocument();
// Create a paragraph element with a namespace $p_element = $dom ->createElementNS(
'my_namespace' , 'p' , 'GeeksforGeeks' );
// Append the child to DOMDocument $dom ->appendChild( $p_element );
// Create another new DOMDocument instance $dom2 = new DOMDocument();
// Check if nodes are same $isSameNode = $dom ->isSameNode( $dom2 );
// Check if the namespace is default or not if (! $isSameNode ) {
echo 'No, $dom and $dom2 are different.' ;
} ?> |
Output:
No, $dom and $dom2 are different.
