(Also provides a native implementation of spl_object_id)
For the safest function in runkit(7).
This implements runkit_object_id() : ?int,
which is similar to spl_object_hash() : string, but returns an integer instead of a string.
The runkit_object_id() is faster if you need to take the ids of a large number of objects, and avoids the memory overhead of storing extra strings.
By default, this provides a native alias (for PHP <= 7.1) for spl_object_id, which is a native part of PHP 7.2.
Add --enable-runkit-spl_object-id=no to the configure options to disable this.
Both runkit_object_id($obj) and spl_object_hash($obj) return identifiers that are unique for the lifetime of the object.
After the object is garbage collected, that identifier can/will be used again.
Supports php 5.3+ and php 7.0+.
See runkit_object_id-api.php for function stubs, and an alternate (slower) pure PHP implementation.
An integer object id has been a requested function for a while.
spl_object_id() is getting added to PHP 7.2, but there's nothing for php <= 7.1
Similar to runkit7 installation steps, but using this repo instead.
If runkit (extension=runkit.so) is installed and enabled, then disable this module.
