Description:
------------
The 2nd example for array_filter shows its usage without a callback to filter empty array elements.

The example does not include entries for zero values, which could cause issues for newer developers who aren't familiar with PHP's type system.

I would suggest updating the example to include zero values:

$entry = array(
             0 => 'foo',
             1 => false,
             2 => -1,
             3 => null,
             4 => '',
             5 => '0',
             6 => 0,
          );

print_r(array_filter($entry));

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.
