Introduction

La classe ReflectionObject rapporte des informations sur un object.

Synopsis de la classe

ReflectionObject extends ReflectionClass implements Reflector {
/* Constants héritées */
const int ReflectionClass::IS_FINAL = 64 ;
/* Propriétés */
public $name;
/* Méthodes */
public __construct(object $object)
public static export(string $argument, bool $return = ?): string
/* Méthodes héritées */
public static ReflectionClass::export(mixed $argument, bool $return = false): string
public ReflectionClass::getAttributes(string $name = null, int $flags = 0): array
public ReflectionClass::getConstant(string $name): mixed
public ReflectionClass::getConstants(int|null $filter = null): array
public ReflectionClass::getDocComment(): string|false
public ReflectionClass::getEndLine(): int|false
public ReflectionClass::getFileName(): string|false
public ReflectionClass::getMethods(int|null $filter = null): array
public ReflectionClass::getName(): string
public ReflectionClass::getProperties(int|null $filter = null): array
public ReflectionClass::getReflectionConstants(int|null $filter = null): array
public ReflectionClass::getStartLine(): int|false
public ReflectionClass::getStaticPropertyValue(string $name, mixed &$def_value = ?): mixed
public ReflectionClass::hasConstant(string $name): bool
public ReflectionClass::hasMethod(string $name): bool
public ReflectionClass::hasProperty(string $name): bool
public ReflectionClass::isInstance(object $object): bool
public ReflectionClass::newInstance(mixed ...$args): object
public ReflectionClass::newInstanceArgs(array $args = []): object
public ReflectionClass::setStaticPropertyValue(string $name, mixed $value): void
}

To simply enlist all methods and properties of an object simply write:

<?php ReflectionObject::export($yourObject); ?>

,which will cause an var_export-like output.
