Syntax:

ReflectionClass::getProperties ($filter): array 

Parameters:this function takes filterparameters, which helps to remove some reflected properties.Return value:this function returns an array of reflected properties.The following programs illustrate the function ReflectionClass::getProperties() in PHP:
Program 1:  
// Definition of a class named Departments class Departments { public $Dept1 = `CSE` ; private $Dept2 = `ECE` ; public static $Dept3 = `EE` ; }  
// Using ReflectionClass over the Departments class $ReflectionClass = new ReflectionClass ( `Departments` );  
// Call the getProperties() function through the filter
// ReflectionProperty::IS_PUBLIC which
// will reflect the results of public properties only $A = $ReflectionClass -> getProperties (ReflectionProperty::IS_PUBLIC);  
// Get array of reflected properties var_dump ( $A ); ?> Output:

array (2) {[0] = > object (ReflectionProperty) # 2 (2) {["name"] = > string (5) "Dept1" ["class"] = > string (11) "Departments"} [1] = > object (ReflectionProperty) # 3 (2) {["name"] = > string (5) "Dept3" ["class"] = > string (11) "Departments"}} 

Program 2:  
// Definition of a class named Company class Company { public $C1 ; private $C2 ; public static $C3 ; }  
// Using ReflectionClass over the Company class $ReflectionClass = new ReflectionClass ( `Company` );  
// Call the getProperties() function without
// any filter $A = $ReflectionClass -> getProperties();  
// Get array of reflected properties var_dump ( $A ); ?> Exit:

array (3 ) {[0] = > object (ReflectionProperty) # 2 (2) {["name"] = > string (2) "C1" ["class"] = > string (7) "Company"} [1] = > object (ReflectionProperty) # 3 (2) {["name"] = > string (2) "C2" ["class"] = > string (7) "Company"} [2] = > object (ReflectionProperty) # 4 (2) {["name"] = > string (2) "C3" ["class"] = > string (7) "Company"}}
