spl_object_hash

    (PHP 5 >= 5.2.0, PHP 7, PHP 8)

    spl_object_hash — Return hash id for given object

    Açıklama

    spl_object_hash(object$object): string

    This function returns a unique identifier for the object. This id can be used as a hash key for storing objects, or for identifying an object, as long as the object is not destroyed. Once the object is destroyed, its hash may be reused for other objects. This behavior is similar to spl_object_id().

    Bilginize:

    When an object is destroyed, its hash may be reused for other objects.

    Bilginize:

    Object hashes should be compared for identity with === and !==, because the returned hash could be a numeric string. For example: 0000000000000e600000000000000000.
