Of course, I may not fully understand the problem. Of course, if it was just mapping includes, that would be too simple to require much of a general solution. However SSI is more than just includes.

And if what they want exceeds their understanding and thus my comfort level, then I walk. Live is too short to work for ignorant people. Realize that if they don't understand the job, then they won't appreciate the effort, and you won't be paid as you should. Several years ago, one guy asked me how much do I charge. At that time I said $50 per hour He replied I've never paid more than $25 per hour -- would you consider working for that? I replied Sure, but it's going to take me twice as long to get anything done. Needless to say, I didn't get hired. A year later he returned and we had the identical conversation again. It was clear that he didn't like the programmers he hired at $25 per hour, but he continued looking. In addition to failing to get what he wanted, he didn't realized that his time is also worth something and he was wasting it by measuring programmers by a single metric.

[1] http://httpd.apache.org/docs/current/howto/ssi.html
Tommy,
Yes, thanks, I did see that:
change !--#include virtual=/includes/old/file/B.inc --
to !--#include virtual=/path/to/php/code2exec.php --
!--#include virtual=/path/to/php/code2exec.php --
does not work on our servers. (I hesitate to say that it doesn't work
anywhere; I don't have enough experience with that.)
What happened when I tried this is that the page displays the raw PHP
instead of the results of the PHP. The server executes the PHP first,
and then executes the SSI instructions, such that the following *does*
work.
?php include('/path/to/php/code2exec.php'); ?
(mind you, I've seen plenty of notes that you should/have to use
virtual() instead)
Regarding SSI not doing anything dynamic: Yes, that's mostly true. The
only dynamism you can get is using if/elsif/else statements while
checkign things like the current URL path, which are ridiculously
clunky.
So the point of this question was to find an *existing and tested*
non-module set of functions that I could employ to translate a
particular include into a set of PHP commands, and then use PHP to add
some dynamic content.
And do you see my main point here, please? I'd use PHP to add some
dynamic content WITHOUT CHANGING THE MAIN CODEBASE that is
unfortunately but definitely stuck in SSI.
I'll probably have to skip that idea, but I'll try to look elsewhere
for such a set of functions. I'd like to write them in the future, but
that's not going to happen within the next couple days. And if anyone
is still scraping their brow at the absolute HORROR that we are using
SSI instead of the PHP that we should be using, please note that the
whole point of keeping the codebase the same everywhere is to move
everything into a new, modern codebase *real soon*.

[PHP] Server Side Include translator as PHP functions
Hello,
Can you please tell me if there's already a set of PHP functions for
translating SSI commands to PHP?
I'm looking to do two things -- one difficult, one easy -- using PHP
on a hosted server.
My client has web pages that use Server Side Includes, and one
sub-site that uses PHP. The task is to make the PHP sub-site use the
same SSI includes as the rest of the site to maintain a consistent
code structure. I can simply use include_once() to include each SSI
include; that works fine. However, I'd like to recognize and replace
one of the SSI instructions with a more nuanced PHP instruction that
will insert dynamic information from the sub-site's environment.
1. include SSI files A
2. include SSI file B, Recognize B and replace it with some PHP code
3. include SSI file C
and i can't actually do that b/c PHP gets run first and then SSI instructions.
So the difficult thing I want to do is to read the SSI files
(literally, using fread or similar), translate them to PHP ('include
virtual' -- include(), set var=foo value=bar -- var foo = bar,
etc), and then execute them.
Then the simple thing I want to do will be recognizing the commands I
want to replace or modify and doing so.
Since this is a hosted solution, I don't believe I can install any PHP
modules, and I'll have to use some functions instead. Does that
already exist, please?

I think you didn't provide enough details to get a more accurate suggestion
of a solution, but here goes... Is 'include SSI file B' always included and
always need to be replaced? If so, that's a very apparent solution. If
not, what are criterias? URL? Query parameter(s) and/or value(s)? Certain
user(s)? Certain group(s) of users? Certain hour of the day? Certain user
agent(s)? etc... Regardless of how dynamic any site is, there's a always
some kind of pattern. What you need to do is identify that pattern and do
what you need accordingly. What about having PHP read those files to be
included and output without having to rely on SSI mechanisms?
I'm just curious... since PHP is OOP and, IIRC of SSI, the use of SSI limits
the full potential of OOP and PHP. Is the control of the application and
configurations beyond yours?

Tommy,
Last question first: yes, using SSI limits the full potential of the
PHP being used, but the point of this exercise is to continue using
the existing SSI includes for this small subsection of the larger
website, and to not recode the larger whole to benefit the smaller
piece. Make whatever Star Trekism of that you will; we simply don't
have time or resources to use PHP everywhere as we should.
I do not understand your question about criteria; the only criteria
for these Apache Server Side Includes is the relative (or
relative-to-root) filepath:
!--#include virtual=/includes/header-pieces/A.inc --
If you mean, which server variables am I accessing with SSI and now
need to access with PHP, I'm primarily concerned with the current
filepath.
SSI include file B is, in this case, the contents of an HTML
webpage's HEAD block. The PHP-based CMS can fill the HEAD with some
useful info unique to the current page. If I can achieve the _actual
problem_ of translating the SSI commands into PHP, it would be a
simple matter for me to insert some additional material into the
middle of the original. The only reason I even mention this simple
problem is because it explains why Im bothering to do this at all. If
all I wanted was to get the unaltered output of the SSI includes, I'd
just continue doing ?php include(/includes/header-pieces/A.inc); ?
and be on my way.
All I want to know is if someone has already written a set of
functions to translate some if not all SSI commands into PHP.
e.g.!--#include virtual=/includes/header-pieces/A.inc --
becomes ?php include(/includes/header-pieces/A.inc); ?
!--#set var=foo value=bar -- becomes ?php var
foo = bar; ?
!--#if expr=${foo} --...!--#elif expr=${bar}
--...!--#else --...!--#endif --
?php if($foo) {...} elseif($bar) {...} else {...} ?
Otherwise, I have to write those functions myself and, inevitably,
spend time I don't have getting it right. I've searched, but I may
easily have missed or not recognized the functions that I need.

Then you should seriously consider the site's function and features and see
if the current application fits that model. Doing little patchwork here and
there may end up costing a lot more time and resources than just rewriting
the application in PHP, IMO, not to mention losing customer/clients because
of buggy application due to patchworks. I'm sure some experienced folks

change !--#include virtual=/includes/old/file/B.inc --

Incoming request - static HTML file - SSI mechanism (included some files)
change the above flow to (there by passing SSI mechanism)
Incoming request - PHP file index.php (include some files, execute PHP
scripts as needed and change the httpd configurations accordingly)

!--#include virtual=/path/to/php/file/handlingRequests.php -- or just
remove the SSI mechanism altogether and have a index.php file doing all the

server overhead. (Migrating the SSI configurations in httpd to PHP codes
shouldn't take that long unless you're new to PHP.)

Re: [PHP] Server Side Include translator as PHP functions
Thanks for the advice, I'm aware of all that, but I'm looking for a specific PHP solution at the moment. Unless you have advice on how I can update the SSI includes on the larger website *without* having to also update the PHP includes for this smaller website? I take it that you don't know of such a function; do you have a recommendation for a good function or program repository I could search? The couple that I was looking at (such as http://php.resourceindex.com/) don't look like they've received a whole lot of attention lately, and may not be the best sources. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Server Side Include translator as PHP functions
Oh, and on our servers you can't call PHP commands from SSI includes. I'm not certain if that's true from all servers, but it's certainly the case that on some servers the PHP runs first and then the server side commands. So !--#include virtual=/path/to/php/code2exec.php -- doesn't work. Gods I wish it did, then I'd simply have rewritten the structural parts of my site in PHP years ago, and been able to use that from my many legacy SHTML files. And thanks for going to all that trouble, Tommy, but I'm looking for existing functions -- to avoid trying to use something just written and then debugging. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Did you look at my suggestion as work around such as replacing the SSI mechanism for a particular path/URL with PHP? Use of 'Conditional expressions' [1] maybe necessary which is beyond the scope of this list. What are SSI? SSI (Server Side Includes) are directives that are placed in HTML pages, and evaluated on the server while the pages are being served. They let you add dynamically generated content to an existing HTML page, without having to serve the entire page via a CGI program, or other dynamic technology. The decision of when to use SSI, and when to have your page entirely generated by some program, is usually a matter of how much of the page is static, and how much needs to be recalculated every time the page is served. SSI is a great way to add small pieces of information, such as the current time. But if a majority of your page is being generated at the time that it is served, you need to look for some other solution. [1] Last time I checked, SSI, either on httpd or IIS, doesn't have any means to do dynamically, including generating headers, as you intended.

[PHP] Functions/methods aliases in PHp 5.2
Hi everyone,
Is there any possibility to make a method or function alias in PHP?
Yes, I know I can do the following:
?php
function foo_bar($x) {
// And so we code...
return $result;
}
function FooBar($x) {
return foo_bar($x);
}
But maybe there is a more elegant solution?
Thanks!

Whilst you can do class_alias() - something I use to hide the long
class name for soap services - there isn't a function alias.
But, if you are creating your own functions, then you could use a
closure and that can be assigned to a variable ...
$fn_FooBar = function() { ... };
$fn_FooBar($a, $b, $c);
or
someFunc($fn_FooBar) { ... }
Closures are ideal for callbacks.
Why do you want to alias functions? Is it to obscure the existing name?
If so, take a look at using an encoder. This uses the compiled code
rather than the source to run.
It is faster to run as there is no compile phase and the code isn't
very easy to reverse.

A couple of things come to mind.
1 - If you create a subclass and were overriding num_rows(), the
subclass would have to also override NumRows(). Twice as much work.
2 - You could use __call() and __callStatic() magic methods, but you'd
have limited options for documentation then (assuming you use
docblocks.
Personally, I would recommend using 1 naming convention and sticking with it.

It sounds like 'register globals' is turned on in your php.ini, and therefore
$name will be visible everywhere, since it is taken from $_POST['name'].

It would be useful to have something like an ifset() function Instead of doing this $v = isset($input) ? $input : $default; we can do this $v = ifset($input,$default); // returns $input if it exists otherwise it will return $default We could also do the same for the empty() function.

Can they make it into 5.3? To be honest, I don't see the compelling need for this. I don't disagree that the functionality is nice, however I quite like the verbose versions as they are clearer to understand without knowing an API function. Also, most of the cases that you would use these functions are with input from GET args and the like. Most frameworks provides wrappers for this with handy ways to get the defaults etc. So overall, I can't see this becoming a core PHP feature.

[PHP] Two very useful PHP functions
Hello, Every so often I have to be using the isset() function to check if a variable exists. It would be useful to have something like an ifset() function Instead of doing this $v = isset($input) ? $input : $default; we can do this $v = ifset($input,$default); // returns $input if it exists otherwise it will return $default We could also do the same for the empty() function. So instead of doing this $v = empty($input) ? $default : $input; we can do this $v = ifempty($input,$default); // returns $input if it is not empty otherwise it will return $default What do you think? Can they make it into 5.3? Best regards __ Raymond Irving

[PHP] Functions not available when run as Scheduled Task?
Don't laugh but we have a Win 2003 Server set up with WAMP, and the PHP/MySQL scripts work great. I set one up to run as a scheduled task: C:\php5\php.exe D:\wamp\www\scriptname.php ...but nothing happens and the Scheduled Tasks log says that it exited with an (ff). So I entered the above manually into a command prompt, and it said that mysql_connect() is an unknown function! WTF? It's like it's trying to use a different php.ini file that maybe has mysql commented out. I double checked that all the php.ini files on the machine do have mysql enabled, and anyway mysql works fine normally.

Try doing this:

phpinfo();
?
Then run the command:
C:\php5\php.exe D:\wamp\www\phpinfo.php D:\wamp\www\phpinfo.html
Then view phpinfo.html in a browser. See how the php.ini and the

else it will never return the value from the function. But it will

[PHP] Functions with Static Variables vs. Classes
For some simple applications I use a function to collect values in a static
variable and to return them when called in a special way, just like this
(fairly senseless) example:
function example($elem='') {
static $store = array();
if (!func_num_args()) return($store);
... do something with $elem ...
$store[] = $elem;
}
I would call this a singleton-micro-class, as it works like a class with
data and methods, but there is always only one of it, having only one
method.
Why do I? Because I dont need to worry about variablescope as if I would use
global variables and I dont have to initialize an object before the first
call (with the scope-problem again). I simply can call it everywhere and
everytime.
Do you have any comments to this approach?

AFAIK the above line should cause an error on the second run of the

I think so - otherwise static Variables would be quite senseless. The line
starting with static is (so do I think) once evaluated at compile-time or at
the first run and the ignored.

I believe it's a compile time definition ... which is the reason you can only
initialize static vars with scalar values (and not the result of expressions or
resources or objects, etc)

[PHP] question regarding type hinting parameters of php functions
Hi, i have tried a current snapshot of PHP 5.3 and have a question regarding type hinting. For example when using the function array_slice(array $array, int $offset, int $length) with a non-integer length parameter, what is the desired behavior? When calling array_slice($array, 0, (float)2); the resulting array is EMPTY. When using the right type array_slice($array, 0, (int)2); it works as expected. Shouldn't there be a notice/warning than just a wrong return value? In my case there is neither a warning nor does it work as expected. (perhaps it do something wrong?) Of course i can use int's, but in my opinion either a warning should be given or the function should gracefully handle the wrong typed parameter.

[PHP] functions versus includes
I just started using PHP and got to think... Without getting into the discussion of best practices, strictly from a performance perspective, what is faster: a function or an include?

(of course one can get all headers and then use the array index to simulate limit offset, row_count). thanks in advance. yashesh bhatia Go Pre http://www2.localaccess.com/rlalonde/pre.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks, Robert Compiled PHP modules could be loaded by any C program (as with any C shared object) but there would be a large number of hoops you would have to jump through before you would be able to make any function calls. However, is the module you wish to use something that is available exclusively to PHP? Most modules are wrappers around existing C libraries and as such it would be much easier to just use the base library rather than trying to emulate a SAPI to load a PHP module. If you still want to go down this path, then reading the manual section about creating PHP modules will give you an insight into how this process works.

I may be going about this the wrong way... is there an easier way? thanks berber
Re: [PHP] PHP Functions as XML or DB
CopyPaste man ;) (Just kidding) Now, seriously, I myself would write a parser for this, fetch some raw data from the pages, and do further processing on those. I didn't checked yet, but I am almost sure that there may be only a few variations of the manual's used html template, and I don't think that it would take you two much time to figure out ways to extract data from each of this variations. On the other hand, I think that this would be a good question to be put on the PHP Manual Mailing List.

Re: [PHP] functions classes
Larry, I have hit similar global names space issues in the past and it is a pain in the behind! One remedial method that can get it stable enough to start to work on is to stick the whole messy lot into classes (NOT OBJECTS!) and then the global name space becomes the local namespace (ie $MyVar becomes $GarbageCode::MyVar). Once you have done this, you can put accessors functions around the class local variables. This means that all new code calls the accessors. $newVar=GarbageCode::GetMyVar(); Thus, if you improve the internal representation of the garbage code, code outside the old garbage code will no longer be impacted by the change. From an FN point of view, you are reducing the access to the variable to a single function point rather than many function points distributed throughout the code base.

In php you cannot create static class variables in this way (doh) or at
least I never have managed. So when faced the this problem I replace
what in C++ would be a class variable with a class function
comme ca:
class MyClass
{
function MyVar($val = null)
{
static $datum;
if(is_null($val))
{
return $datum;
}
$dataum=$val;
}
}

RE: [PHP] Brain Death - [PHP] functions classes
Rob,
I'd go along with the setting a var to null issue (in the cases I have worked
so far on, there has not been a need to set variables to null). However, what
is wrong with is_null()?
From the php manual chm:
(PHP 4 = 4.0.4, PHP 5)
is_null -- Finds whether a variable is NULL
Description
bool is_null ( mixed var )
Finds whether the given variable is NULL.
Parameters
var
The variable being evaluated.
Return Values
Returns TRUE if var is null, FALSE otherwise.
And to be very pedantic - as null does not have a type then actually 'x ===
null' should evaluate to absurdity, but PHP is more pragmatic than that ;-)

But also I'd recommend fixing the the problem whereby you
can't set $datum to the null value, otherwise you may run
into unexpected issues down the road.
?php
class MyClass
{
function MyVar( $val=null, $set=false )
{
static $datum;
if( $set === false )
{
return $datum;
}
$datum = $val;
}
}
?
Cheers,
Rob.

RE: [PHP] Brain Death - [PHP] functions classes
Right or wrong - C does not actually have NULL :-) NULL in C is simply mapped to zero. It is useful in logic to sometimes use mapping of logical sentence letters to numbers and use mathematics to perform proof, but that is a special case. In languages like C, there is no special method of marking a variable as true NULL. Thus, the language has no way of processing three state logic. In SQL, there is a special flag to note that variables are truly null and so it can process three state logic. PHP is odd because it does have a special NULL state but it does not fully support three state logic. But hey - it is a web scripting language - it would be a shame if PHP got all theoretical on us! BTW: Rome... Oh btw, PHP draws strongly from C, and in C NULL == NULL, and NULL == NULL === TRUE It is NULL === NULL == absurd. So - my approach: I may well use is_null() in low traffic areas on PHP, but then when in an inner loop etc, use === null and maybe comment what it means.

[PHP] functions classes
Can anyone tell me if it is relatively an easy process for an experienced coder (not me) to convert a php script to mainly functions/classes. I have my own script that i would like to make more streamlined as it is becoming very difficult to work with. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
