buildUniqueId()
buildUniqueId(string $hook, string|array $function, integer|boolean $priority) : string
Build Unique ID for storage and retrieval.
Simply using a function name is not enough, as several functions can have the same name when they are enclosed in classes.
Parameters
| string | $hook | |
| string|array | $function | Used for creating unique id |
| integer|boolean | $priority | Used in counting how many hooks were applied. If === false and $function is an object reference, we return the unique id only if it already has one, false otherwise. |
Returns
string —unique ID for usage as array key
