I analyzed the top 1500 Composer packages to find and categorize usages of =
the=0A=
`__sleep` and `__wakeup` methods. There are a total of 250 `__sleep` method=
s=0A=
and 259 `__wakeup` methods in these packages (509 total).=0A=
=0A=
Of these, 108 are empty methods containing no code. Most of these are stubs=
=0A=
in the jetbrains\phpstorm-stubs package.=0A=
=0A=
Another 152 of the methods contain only a single throw statement.=0A=
=0A=
This leaves 160 `__sleep` methods and 89 `__wakeup` methods (249 total) whi=
ch do=0A=
something else. 150 of these (over 60%) exist in just 9 packages:=0A=
=0A=
* doctrine\orm - 14=0A=
* drupal\core - 38=0A=
* laminas\laminas-server - 7=0A=
* maatwebsite\excel - 7=0A=
* magento\zend-db - 7=0A=
* pdepend\pdepend - 31=0A=
* roots\wordpress-no-content - 6=0A=
* symfony\mime - 8=0A=
* symfony\symfony - 32=0A=
=0A=
Outside of the above packages, `__sleep` and `__wakup` methods generally se=
em to=0A=
be few and far between.=0A=
=0A=
I created a Google Sheet to view the per-package statistics:=0A=

yYm6V6Y8/edit?usp=3Dsharing=0A=

The raw code for each `__sleep` and `__wakeup` method can be viewed here:=
