The SplObjectStorage::getinfo() function is an inbuilt function in PHP which is used to get the data associated with the object by the current iterator position. Syntax:

mixed SplObjectStorage::getinfo()

Parameters: This function does not accept any parameter. Return Value: This function returns the object associated by the current iterator position. Below programs illustrate the SplObjectStorage::getinfo() function in PHP: Program 1: 

php




<?php
 
// Create New Empty Storage Class
$str = new SplObjectStorage();
 
$obj1 = new StdClass;
 
$str->attach($obj1, "GeeksforGeeks");
 
$str->rewind();
 
$object = $str->current();
     
// Get info into $data
$data   = $str->getInfo();
     
// Print Result
var_dump($object);
var_dump($data);
 
?>

Output:

object(stdClass)#2 (0) {
}
string(12) "GeksforGeeks"

Program 2: 

php




<?php
// Create an Empty SplObjectStorage
$str = new SplObjectStorage();
 
$obj1 = new StdClass;
$obj2 = new StdClass;
$obj3 = new StdClass;
$obj4 = new StdClass;
 
$str->attach($obj1, "GeeksforGeeks");
$str->attach($obj2, "GFG");
$str->attach($obj3);
$str->attach($obj4, "DSA");
 
$str->rewind();
 
// Iterate and print data on each index
while($str->valid()) {
    $index  = $str->key();
    $object = $str->current();
    $data   = $str->getInfo();
 
    var_dump($object);
    var_dump($data);
    $str->next();
}
?>

Output:

object(stdClass)#2 (0) {
