In some cases, when an environment is unclean, tests might get stuck fe
when some incorrect ini file is loaded. As the test depends on the core
only, it is safer to explicitly ignore the ini. Any ini can be passed in
the cmd itself, if needed.
array_values():
When the input is an empty array or a packed array with no gaps,
return the original array.
array_keys():
When the input is an empty array, return the original array.
When the input is a packed array with no holes
(and no search key specified), populate the return with
a simple range(0, count($input) - 1)
For historical reasons, fsockopen() accepts the port and hostname
separately: fsockopen('127.0.0.1', 80)
However, with the introdcution of stream transports in PHP 4.3,
it became possible to include the port in the hostname specifier:
fsockopen('127.0.0.1:80')
Or more formally: fsockopen('tcp://127.0.0.1:80')
Confusing results when these two forms are combined, however.
fsockopen('127.0.0.1:80', 443) results in fsockopen() attempting
to connect to '127.0.0.1:80:443' which any reasonable stack would
consider invalid.
Unfortunately, PHP parses the address looking for the first colon
(with special handling for IPv6, don't worry) and calls atoi()
from there. atoi() in turn, simply stops parsing at the first
non-numeric character and returns the value so far.
The end result is that the explicitly supplied port is treated
as ignored garbage, rather than producing an error.
This diff replaces atoi() with strtol() and inspects the
stop character. If additional "garbage" of any kind is found,
it fails and returns an error.
Hereby, interned strings are supported in thread safe PHP. The patch
implements two types of interned strings
- interning per process, strings are not freed till process end
- interning per request, strings are freed at request end
There is no runtime interning.
With Opcache, all the permanent iterned strings are copied into SHM on
startup, additional copying into SHM might happen on demand.
