The ArrayObject::setFlags() function is an inbuilt function in PHP which is used to set the flag to change the behavior of the ArrayObject.

Syntax:

void ArrayObject::setFlags( int $flags )

Parameters: This function accepts single parameter $flags which holds the behavior of new ArrayObject. This parameter holds either a bitmask or named constants.

Return Value: This function does not return any value.

Below programs illustrate the ArrayObject::setFlags() function in PHP:

Program 1:

<?php  
// PHP program to illustrate the  
// ArrayObject::getFlags() function  
  
// Declare an array and convert 
// it into array object 
$arrObject = new ArrayObject( 
    array('Geeks', 'for', 'Geeks') 
);  
  
// Use ArrayObject::getFlags() function 
// to get the behavior of flags 
$flag = $arrObject->getFlags();  
  
var_dump($flag);  
  
// Set a new flags 
$arrObject->setFlags(ArrayObject::ARRAY_AS_PROPS); 
  
// Use ArrayObject::getFlags() function 
// to get the behavior of flags 
$flag = $arrObject->getFlags();  
  
var_dump($flag);  
  
?> 

Output:

int(0)
int(2)

Program 2:

<?php  
// PHP program to illustrate the  
// ArrayObject::getFlags() function  
  
// Declare an associative array 
$arr = array( 
    "a" => "Welcome", 
    "b" => "to",  
    "c" => "GeeksforGeeks"
);  
  
// Create array object  
$arrObject = new ArrayObject($arr);  
  
// Use ArrayObject::getFlags() function 
// to get the behavior of flags 
$flag = $arrObject->getFlags();  
  
var_dump($flag);  
  
// Set a new flags 
$arrObject->setFlags(ArrayObject::STD_PROP_LIST); 
  
// Use ArrayObject::getFlags() function 
// to get the behavior of flags 
$flag = $arrObject->getFlags();  
  
var_dump($flag);  
  
?> 

Output:

int(0)
int(1)
