PHP lacks two very basic functions for working with arrays:
- array_first() returning the first element of an array (or null)
- array_last() returning the last element of the array (or null)
While PHP has functions that return the first and last keys,
array_key_first() and array_key_last(), it do
I would like to suggest changing the name or removing the nextFloat() method,
which is coming to PHP 8.3.
The Random\Randomizer class will have two new methods for generating
random numbers:
- getFloat($min, $max [, $boundary])
- nextFloat()
Now please try to guess what these methods do and, more

h magic contant:
$obj = factory(MyClass::__CLASS__); // returns object Foo\MyClass, very
understandable :-)
$obj = factory(Bar::__CLASS__); // returns object Other\Bar, as use
statement declares :-)

feature of PHP 5.3 would be to resolve this errors.

need to be optimized. The only time
you can really tell its slower is in synthetic benchmarks.
Few hundred operations involving ternary operator is nothing unusual ;)

In PHP there is no function for escaping JS strings and json_encode is
useful compensation. I use it this way very often.

don't know how difficult it is to implement, but it can be very useful
speed optimization for PHP 5.3 to improve ternary operator to use
reference counting.

Snapshot 5.3.0alpha3-dev acts like manual, I think the manual is correct.
BTW - this is very useful feature. A "wrong-relative-resolving" rescuer ;)

Hi!
but it generates Warning: The use statement with non-compound name
'ArrayObject' has no effect.
The warning is correct.
It is not correct - the use statement has effect, as documented in
manual http://php.net/manual/en/language.namespaces.importing.php.

ive when it
is needed - using 'namespace' operator (as equivalent of the 'self'
operator). So I think now there is no reason to use default relative
resolving and it should be removed.
What about voting?

I have downloaded last Mono source code (http://www.mono-project.com/,

true, however i have a counter example: classes from more general namespace
that use further nested classes (think some kind of behaviour and different
drivers/plugins for example).
so while it's true that more nested classes usually extend the less nested
ones it also common for more generic
let's look at this code:
There are a few things to keep in mind. PHP has __autoload(), which C#
does not have. Thus, a solution such as:
1) try foo\classes\foo\stuff
2) try foo\stuff
Greg, this is clear. I am trying to point something different - to try
ONLY 2) and never try 1).
Why
fails.

. There would have been anything that could have changed this
without creating any sort of BC issues. From the possible namespace
separators, \ was the best one as we could see. That's how it is, that's
I will be glad for each separator, but :: is the best one :-))
