Hello !

I have never been able to load mssql extension in my life...In my php
.ini file, I removed the ; correctly :
extension=php_mssql.dll
Other extensions work fine, for example I use the PDF extension :
extension=libpdf_php.dll
When I call phpinfo(), I can see informations about PDF, but nothing
about mssql.
I was wondering if I have the good version of the dll in my "ext"
directory..Or is SQl server 2003 compatible with XP and the latest
version of php?
By the way, SQLServer works fine on my computer.
Thank you very much

I am using Smarty templates to format HTML emails from the command
line (using cli). My typical command is:
php filename.php
However, and I am struggling with templates that are greater than 10k.
It looks like the Smarty output is getting truncated at about 10k.
Smarty uses output_buffering, so I need to be set the output_buffering
directive to "1" or "On" or "1000000", or something other than "Off".
But I have not been able to do that.
I have changed the output_buffering setting in /.../cli/php.ini (as
well as /.../apache2/php.ini & /.../cgi/php.ini for good measure).
And that does seem to have an effect.
Here is what the output from phpinfo() is from the command line:
Directive => Local Value => Master Value
....snip...
output_buffering => 0 => 1000000
output_handler => no value => no value
...snip...
So in other words, when I change the value in my /.../cli/php.ini, the
"Master Value" changes. However, the "Local Value" stays at "0".
In my code, I am testing for the value of output_buffering (using
ini_get("output buffering")), and its value is always "0" (same as the
"Local Value" that is output from the phpinfo().
So my question is...how do I turn on output_buffering correctly from
the command line? Am I configuring the /.../cli/php.ini file
correctly? Is something in my code (maybe an included library) maybe
setting that value without me knowing? Am I looking in the wrong
place / headed in the wrong direction?

dunno if this was a typo on your part, but shouldnt it be,
ini_get("output_buffering") ?

you might not be getting your settings from the ini file you think you are,
or there could be another one in the way. just for the hell of it, why not
give
php --ini
a shot, see if something unexpected crops up, and maybe poke around in all
of those files.
also, this brings up the point of setting local values on the cli. im not
sure how to do it. w/ apache, you can supply a .htaccess file which allows
you to alter values in the 'local' column of the phpinfo() output. anyone
know how to do it on the cli ?

This is a great idea...and I tried this but I'm using php 5.1.x and
--ini flag is not available until 5.2.something. <sigh>

Exactly my thoughts...anyone out there know?

I think I solved this issue by using the -d option on the commandline.
When I use:
php -d output_buffering=On ./filename.php
the local value / active value of output_buffering is correct.

Casting only works between "easily convertable" types. A string does not
easily convert to a classic object. One could ask if it would just pass to
the constructor, but it doesn't. I don't know if there's a technical reason
for that or if just no one implemented it, but the short answer is "The
language doesn't do that."
(What may be confusing you is __toString(), which only works for *reading* if
you *already have an object* and then use it in a string context. You don't
already have an object and are trying to *write*, so the __toString() does
nothing.)

in some languages, such as java, the syntax "", is merely syntactic sugar
for creating an instance of a class, say String. in such languages creating
a subclass of String, would give you the ability to cast in the way you have
done. however, in php a string is a primitive type and nothing more,
therefore the above will not work.
furthermore, i dont see what enhancement youre adding to strings in the code
fragment is anyway. you can still pass around string variables and echo
them at any time. one thing i have used __toString() for is in a subclass
of SimpleXMLElement, where SimpleXMLElement::asXML() returns a string
representation of the instance, i have added
public function __toString() {
return $this->asXML();
}
to make it a bit more elegant, imho ;)
and lastly, as a side note / mini rant; since ive been mumbling about java
so much lately, i would like to take a second to mention that objective-c,
in particular the apple cocoa framework, is another language that supports a
string literal syntax for a class. an NSString instance can be represented
literally by @""; and im sure there are other examples out there as well.

That's what i was asking about, when trying to "cast" something into a non
native type ( ie a class ), just fire the constructor. Would'nt it be great
?
$myvar=(array) somefunc();
$myvar=(myarrayextented) somefunc();
( what should be exactly the same as )
$myvar=new myarrayextented(somefunc());
But with a lot more of coolness !

A class is a syntactic way of grouping behavior and data together in an
encapsulated fashion (at least that's the PHP definition).
A formal package is a syntactic way of grouping related classes together,
either for easier distribution, somewhat tighter coupling, or syntactic
sugar. For instance, you could have 5 classes that make up your "Database
abstraction" package; they're all discrete, but all work in concert.
PHP does not have a syntactic "package" concept. The closest thing would be
namespaces as implemented in PHP 5.3, but that's not out yet. Many systems
emulate packages with verbose class naming (eg, Database_Connection,
Database_Query, Database_Transaction, Database_Query_Select, etc.), but I
personally find that ugly. :-)

furthermore, in languages such as java (and likely others) packages have
access levels which are conceptually similar to ppp in classes. this allows
designers to limit access to certain classes in a given package (duh); it
turns out to be quite useful. imagine you are a library author and some of
the classes you distribute, you dont intend for your clients to use, well
then, you simply mark those classes as private.
i dont believe the php namespace concept incorporates this feature, nor do i
think its really relevant, in a source based language. however, i do find
it relevant to the discussion ;D

Hello All,
What is the best method to build and deploy php scripts along the different
environments? You can talk about rpm's and stuff
My specific scenario is
Step1:
Developer checks code in to perforce (repo)
Step 2:
Then I need to upgrade my integration instance.
Step 3:
Upgrade QA instance
Step 4:
Upgrade staging Server
Step 5:
Upgrade production machines
What would be the specific build mechanism that I can use for such kind of
environments? I also have db scripts that might alter schema.
Please provide me samples of any scripts that you might have written to
achieve this kid of structure. Any suggestions or scripts will be highly
appreciated.
Personally, I use various branches in our repo to do this kind of roll
out. I have various (simple) scripts that do all the updating on the
various environments and it's usually just a matter of switching to a
different branch.
It kind of depends whether all of your productions environments are
under your control or not. If they are then you can do a kind of direct
access to your repo on them (security considerations aside).
On production, I personally do a pull from the repop to an offline area
on a "master" production server, do rsync dry-runs to online areas (to
get the disc cache all warmed up) to each production server (there can
be more than one!) and then do a quick: disable, rysnc, update, enable
run to do the final deployment.
If we know there are no race type issues in our deployment we can opt to
avoid the disable/enable bit of it and just deploy it live.
Not much in the way of attached scripts but that how I do it and it
works pretty well :)
As a side note, if you have larger load sites, you'll probably be doing
some caching cleverness with APC (or similar), in which case you'll
probably want to invalidate some caches before update. In order to
prevent spike loading upon enabling again, you may also want to do some
kind of "priming" of the caches before opening it all to the public.

Hullo!
I'm having a pig of a time trying to figure this one out: I have an
XHTML document which I've loaded into a DOMDocument because I want to
add more tags to it. However, since I live in a bilingual country, I
want to get the document's xml:lang attribute so I know what language
to add my new tags in.
I want to write
$lang = $page->documentElement->getAttribute('xml:lang');
OR
$lang = $page->documentElement->getAttributeNS('xml', 'lang');
but both of these return empty strings, indicating that it cannot find
the xml:lang attribute. And yet,
$page->documentElement->hasAttributes() returns true and
$page->documentElement->attributes->getNamedItem('xml:lang')->nodeValue;
works correctly. So why doesn't my preferred code?
