Hi Nicolas,

=20

Have you checked the impact of changing the existing function? Like

=20

https://github.com/sebastianbergmann/phpunit/search?utf8=3D%E2%9C%93 =
<https://github.com/sebastianbergmann/phpunit/search?utf8=3D%E2%9C%93&q=3D=
spl_object_hash> &q=3Dspl_object_hash

umper/Cloner/VarCloner.php

pport/Randomid.php

Obviously there will be more. Seems some stuff even depends on the exact =
output. So it would be most likely a BC break.

=20

Now, I=E2=80=99d see this more like a feature request, as Julien was =
mentioning another function at the start. But IMHO opinions from people =
specializing on test/debug user land tools would give a better sight, so =
CC=E2=80=99ing.=20

I also know people that print_r($an_object) and parse the output just to
extract the object handle from there... Crazy isn't it ?

=20

I plead guilty for doing this, but php let me no better choice for now =
;)

The attached patch removes the XOR hashing for the object handle (it's =
useless, the "secret" is trivially guessed after parsing the output of =
var_dump).

It would be awesome if this patch could be applied for php 7.0!

Cheers,

Nicolas
