Is the "echo $mySQL_user;" inside of a function?  I believe you'll
need to say "global $mySQL_user;" to gain access to it if so.

[PHP] include() Error

[Ron Piggott]

Good morning all:

I have recently purchased a computer and am using it as a dedicated server.  A 
friend helped me install PHP and configure.  I am saying this because I wonder 
if using a newer version of PHP (compared to my commercial web host) may be the 
reasoning behind the error I am receiving.  

I created a function to generate a form submission key.  
- This created hidden variable for forms
- This is also session variable 

With this function I have an ‘ include ‘ for the file containing the mySQL 
database, username and password.  I know this file is being accessed because I 
added:

===
echo $mySQL_user;
===

following the login credentials.  

But when I remove this line from mySQL_user_login.inc.php and place within the 
function on the line following the include the "echo” returns nothing.  

===
include("mySQL_user_login.inc.php");

echo $mySQL_user;
===

Can any of you tell me why this is happening?

I won't claim a deep understanding of the PHP internals, but I have enough
experience with varied compiled and interpreted languages and using PHP and
APC that I'm confident that the process to include a file involves:

1. Load the opcodes
A. Either read the file from disk and parse the PHP into opcodes, or
B. Load the cached opcodes from APC.
2. Execute the top-level opcodes

Any syntax errors--even those in unreachable code blocks--will cause the
script to fail parsing. For example,

if (false) {
function foo() {
SYNTAX ERROR!
}
}

will cause the parse to fail even though the function cannot logically be
defined. PHP doesn't even get that far.

PHP Parse error:  syntax error, unexpected T_STRING in php shell code

While out of convenience you might be tempted to include the file in every
script, when considering performance alone you should include the file only
in those scripts that will make use of its contents.

In terms of redoing the test with "real world files", that's an
entirely different debate (and one I won't enter into at this time,
though this list has discussed this topic before, most recently in a
post Ted made talking about screen height.)

The point is, there is a real difference. The question remains if the
difference is enough to act on in future code bases (and I would say
yes if my tests showed this difference, you may say no.)

Those trends/results depend significantly on the contents of the
functions, too. The overly simplistic example we've used both helps
and hurts the analysis (I'll admit my example likely has more
functions than other 5K/50K files, and I suspect most functions
require more complicated work behind the scenes to build up than echo
statements.)

The point I'd make here is that it's very difficult to have apriori
knowledge of how something will perform without testing it.

Ummm... sure. What did you say about real world before :)

I interpreted it as: I have a 50K library, and some files only use
10%, some use 20% and some 30%. To be able to include it separately,
you would need to split and some would need to include maybe 3 or 4
files.

Finally, you're the first one that actually has measured something.
You should redo your test with real world files, because in real world
functions aren't that small.
In functions with more lines (say ~100 lines per function), you'll see
a different ratio between 5k and 50k. In my tests it is:
- 5K: 22ms
- 50K: 34 ms

When I create files that only contain 1 function, with just a number
of echo "Hello world"; lines until 5k or 50k, the results are:
- 5K: 15 ms
- 50K: 17 ms

[B] does not negate [A]. There's a difference between parsing the
syntax and defining functions, classes constants and globals, and
generating bytecode. In a 'normal' file I guess syntax definitions are
only about 5% of the total contents, the rest can be ignored until
being called.

I believe this is untrue. PHP generates the bytecode and then parses
the bytecode per request to generate the userland infrastructure,
including classes and functions, for the entire include file. During
the generation of bytecode, PHP doesn't know apriori which functions
will be called at runtime. I suspect if you asked for confirmation of
this on the internals list, they'd confirm this. In terms of errors,
there are certainly different stages that errors can occur, and what
you're referring to are runtime errors. Runtime errors don't
necessarily show up in every possible execution branch. That doesn't
mean that PHP didn't generate the code for the userland functionality.

Here's where I believe we have a communication issue. I never spoke of
splitting up the library into 3 or 4, or any number of different
files. The opening post states that only 10% of the pages need the
library. I suggested that he only include the library in the 10% of
the pages that need the library. That said, it's possible I
misinterpreted him.

I will say that I do disagree with your analysis that difference
between loading a 5K or 50K php file is extremely small. So I just put
this to the test.

I created a 5K file and a 50K file, both of which have the form:

function hello1(){
echo "hello again";
}

function hello2(){
echo "hello again";
}

etc.

I have XDegub installed, have APC running, warmed the caches, and then
test a few times. There results all hover around the following:

Including the 5K requires around 50 microseconds. Including the 50K
requires around 180 microseconds. The point is that there is a
significant difference due to the work PHP has to do behind the
scenes, even when functions (or classes, etc. are unused.) And,
relevant to the dialog for this current thread, avoiding including an
unused 50K PHP on 90% of the pages (the pages that don't need the
library) will lead to a real difference.

 [B] negates [A]. PHP must either parse the file into opcodes or load them
from APC and further execute the top-level opcodes. That means defining
functions (not calling them unless called directly), constants, global
variables, classes, etc. No amount of measuring is required to tell me that
doing X vs. not doing X in this case clearly takes longer.

Now, is that time significant enough to warrant the extra logic required?
In my case, absolutely. We organize our library into many classes in
multiple files. By using an autoloader, we simply don't need to think about
it. Include bootstrap.php which sets up the autoloader and include paths.
Done.

In the case with a single 50k library file that is used on 10% of the
pages, I'd absolutely require_once it only in the pages that need it
without measuring the performance. It's so trivial to maintain that single
include in individual pages that the gain on 90% of the pages is not worth
delving deeper.

First of all, I believe PHP is smart enough to not generate bytecode
for functions that are not used in the current file. Think about the
fact that you can write a function with errors, which will run fine
until you call the function. (except for syntax errors).

The speed difference between loading 5K file or 50K file (assuming
continuous blocks) is extremely small. If you split this library, you
would have PHP files that require you to load maybe 3 or 4 different
files to have all their functions. This would require 3 or 4 more file
searches, first the file needs to be located in the file table, then
on the disk. If you compare the required time for those operations,
they are enormous compared to time needed for a bigger file.
Just for the facts, if you're on a high end server drive (15000RPM
with 120MB/s throughput), you would have an average access time of
7ms. (rotational and seek time). Loading 5k with 120MB/s thereafter
only takes 0.04ms. 50k would take 0.4ms. That would save you 0.36ms if
a file only needs 1 include, if you need 2, that would cost you 6.68
ms. 3 would cost 13.72 ms, etc. With an 3.8GHz CPU, there are approx
4.000.000 clock cycles in 1ms, so in this case you would lose for only
loading 2 files instead of one, approx 27.250.000 clock cycles.. Think
about what PHP could do with all those clock cycles..

Maybe I misinterpreted the question, but I don't think I agree.

If you have a 50K PHP file that's only needed in only 10% of the
pages, then, when solely considering performance, that file should
only be included on the 10% of the pages that actually use the file.
Now, there are reasons where you might want to include the file
globally (maintenance purposes, etc.) Loading the 50K of PHP code
requires building up all of the associated infrastructure (zvals,
etc.) for the user code (even if APC is used, the cached opcode/PHP
bytecode still has to be parsed and built up for the user-defined
classes and functions per request, even if they're unused), is
certainly going to perform more slowly than selectively including the
library on only the pages that need the library.

Since searching for files is one of the most expensive (in time)
operations, you're probably best off with only a single PHP file. PHP
parses a file initially pretty quickly (it's only checking syntax half
on load), so unless you're having a 100MHz CPU with SSD drive, I'd say
go with a single PHP file. If you make sure the file isn't fragmented
over your disk, it should load pretty quick to memory. I'm not sure if
PHP caches that much, but if you really care, take a look at memcached
or APC.

[PHP] include selectively or globally?

[Haluk Karamete]

With this question, I aim to understand the inner workings of PHP a
little better.

Assume that you got a 50K library. The library is loaded with a bunch
of handy functions that you use here and there. Also assume that these
functions are needed/used by say 10% of the pages of your site. But
your home page definitely needs it.

Now, the question is... should you use a global include that points to
this library - across the board - so that ALL the pages ( including
the 90% that do not need the library ) will get it, or should you
selectively add that include reference only on the pages you need?

Before answering this question, let me point "why" I ask this question...

When you include that reference, PHP may be caching it. So the
performance hit I worry may be one time deal, as opposed to every
time. Once that one time out of the way, subsequent loads may not be
as bad as one might think. That's all because of the smart caching
mechanisms that PHP deploys - which I do not have a deep knowledge of,
hence the question...

Since the front page needs that library anyway, the argument could be
why not keep that library warm and fresh in the memory and get it
served across the board?

When answering this question, please approach the matter strictly from
a caching/performance point of view, not from a convenience point of
view just to avoid that the discussion shifts to a programming style

Yes, it is definitely allowed. The syntactic sugar of using parens
around the include subject is optional, as it is in other parts of php
as well. That said, it's usually better to include the syntactic sugar
so as to make future maintenance concerns easier -- there's less chance
of a future change to introduce an error if it's clear what things are
grouped with what. Much less of a concern in this case, but more of a
concern in, say, compound expressions.



are all equivalent, because php interpolates variable references in
double quoted strings.

Ah, okay, I'm not at all familiar with websockets, so I'm going to have
to step out of this. Good luck with it!

Hmmm, I think perhaps I've not made myself clear - sorry about that. At present 
I'm using AJAX and apache; I'd like to *stop* doing that (and not use another 
web server, either). In my case, client and server are the same machine - the 
user's machine. There is a browser window and JavaScript within it which makes 
the AJAX requests. I just happen to use apache to have a variety of PHP scripts 
run to provide results back to the browser window.

At present these scripts generally are short-lived, but with some notable 
exceptions. Hence my exploration of whether I could use websockets instead.

Forgot to address this in my previous e-mail because I was cooking
while trying to read/reply my e-mails.  Anyway, if I'm not mistaken,
what you're trying to do is making a threaded application.  PHP does
not support threads currently.  PHP and threads has been a heated
discussion on this list in the past.  You're welcome to search the

You didn't understand my 2nd point completely.  The 2nd point starts
with what function/purpose does the app provide such as is it an
e-commerce, CMS, forum, etc...  What you're talking about is the
process(es) which facilitate(s) the application's functions ie:
"there's more than one way to skin the cat" - so to speak.  Which is
part of manageability, portability, expandability (ie: scaling to
clusters, ease of 3rd party plugins, etc), etc

That's why I suggested you read up regarding OOP, including Interface
and Abstracts.  In OOP, you define and guaranteed certain
functionalities with Interfaces - hence the term API (Application
Programming Interface) - but you pass a super/parent class or any of
its sub/child classes, implement those interface(s), to do the work
needed as how you want things done based on certain criteria.  Classic
example:

1) connect to db
2) execute query
3) fetch results
4) process results
5) close connection

given those 5 above steps, there are many ways to proceed about it.
Which way you choose depends on my 2nd point.  In the past, the
standard practice was using client library such as MySQL or MySQLi,
especially prior to PHP5.  Now it's done via PDO or other data
abstraction layer, including ORM depending on a lot of things:
experience, skills, knowledge, project dead line, personal
preference/style, best coding practices, and lazyness in that given
moment - not particularly in those order either.

I'm really not sure what you're looking for here -- that is pretty
standard php practice to load php files with include -- what were you
expecting here?

While it's certainly possible to rig up something using sockets, I don't
think that's how AJAX works, and you'd need a JS library that did.

As an alternative, can you set up a lightweight web server like lighttpd
and fastcgi on your host machine? This should give you the speed and
flexibility without incurring the overhead of loading everything into
mod_php under apache. The alternate server would listen on a different
port and dispatch fastcgi to deal with the php scripts.

As well, you could run fastcgi from apache to dispatch the smaller
scripts if you didn't want another web server running, although in
practice this hasn't proven to be an issue for me.

Generally, you should only really need to dynamically replace parts of a
long-running program if you don't want to restart it. However, php
scripts are not long-running programs in general, unlike the apache
server itself, for example, and certainly if the php scripts are running
under apache, they will be time- and space-limited by whatever is set in
the php.ini file. If these little scripts are merely responding to AJAX
requests, they should be really short-lived.

OTOH, if you do have a need to replace an include file, you can include
it again unless you use something like "include_once" or
"require_once". Otherwise, the bare "include" and "require" commands
will merrily go ahead and re-include the file. What you really need to
watch out for is dealing with initialization of variables in the include
file, and if what you're including are classes that the previous version
has objects out for, what happens then is going to be pretty strange.

That's what I'm doing - gathering information about bits of PHP that I've not 
used (or not used very much) before to see how my new setup could be structured.

I have a clear idea about *that*. I want to figure out if it's possible to use 
web sockets with a small server written in PHP to replace my current structure 
of ajax + apache + processes (which I suppose it forks). I see these benefits:

1) possible benefit - presumably when an ajax request arrives, a new process is 
started and so PHP has to be loaded and initialised each time. But perhaps this 
is in some way optimised so the PHP process is left running and apache then 
just tells it to read/execute a new script.

2) Definite benefit - when a browser makes an ajax request to run a script, it 
gets no information back until the script completes. Then it gets all of it. I 
have a couple of unsatisfactory workarounds for that in my existing structure. 
Websockets appears to offer a way for the browser to receive timely information.

I do want to use it but would like to be able to replace it with a newer 
version. If there is no way to do this then that is a data point.

And here's another question. Can a child forked by pcntl_fork() use a socket 
that the parent obtained? Reading the socket stuff in the PHP doc, there are a 
number of user-supplied notes hinting this might be problematic.

Tim,

I think you're approaching this the wrong way.
1) have a clear understanding of PHP - syntax, capabilities, etc.
2) have a clear understand of what you're intending to do -
application's function/purpose, features, manageability,
expandability, portability, etc...
3) understand design patterns

What your asking is practically impossible in any programming language
akin to 'how to un-import packages in Java' or 'how to un-using
namespace in C#'.  If you don't want to use it, don't include it ;)
If this is running as web app, you can use header [1] and pass the
criteria for next phase of the operation as URL parameters.  But doing
this is going to kill the server side with too many unnecessary round
trips.  Which clearly demonstrates point 2 and 3.  You should look
into Interfaces, and Abstract under OOP [2].

[PHP] include

[Tim Streater]

At the moment I'm using an instance of apache to run PHP scripts, as and when 
required via AJAX. Having got some understanding of web sockets, I'm minded to 
look at having a small server to execute these functions as required. The 
scripts, some 50 or so, are only about 300kbytes of source code, which seems 
small enough that it could all be loaded with include, as in:



This appears to work although I couldn't see it documented.

I'd also like to be able to replace a module without restarting the server. I 
couldn't see a way to drop an included file, do I therefore take it that there

Re: [PHP] include() and duplicate function definition

[David Nelson]

Hi guys, :-)

Just FYI, I got this answer from the theme dev:

"David,
You don't need the include statement. If you create your function in
wp-content/themes/suffusion-child/functions.php it will get
automatically included.

Secondly, using the same function name wouldn't work, because it would
require me to encase the original function definition in actions.php
in a "function_exists" clause. I would suggest using a different
function name, then using remove_action to remove the older action and
add_action to add the new action."

(http://www.aquoid.com/forum/viewtopic.php?f=4&t=3070)

I'm not yet confident about how to actually implement this in code...
Any tips or advice would be gratefully heard.

Steve, maybe the above informs? In any case, the function to be

I am curious on how this would work, if for some reason they were using
a different template?   the function you want to "overwrite", wont be
used, and therefore, wouldn't your app/template/whatever be updated
improperly than waht you expect it to be?

It's a WordPress issue. When theme updates become available from the
original vendor, you can update them from within the admin backend. In
that case, any hacks you've applied (such as removing a function) get
overwritten. So the evangelized solution is to create a child theme.
The child theme incorporates only files that you've added or changed,
with the original parent theme being used for all others.

Easy peasy if you want to *add* a function.

But, if you want to *modify* a function, you're faced with the problem
of the original function still being present in the parent theme files
and of your having to define a function of the same name in your child
theme (if you change the function name, you then have to hack other
code further upstream, and the work involved becomes not worth the
bother). Somehow, I would need to make my hacked function *replace*
the original function, *without* touching the original function...

It seems like that's not possible and I'll have to find another
solution... unless my explanation gives you any good ideas?

Just to put the dots on the I's, the original "actions.php" contains a
lot of *other* functions that I don't want to touch, and that I do
want to leave exposed to the updates process. It's just one single
function I want to hack...

Sticky problem, huh? :-)

David,

I re-read your original post. And noticed you include the function 
inside your child action.php
Is there a special reason for that? You want to overwrite the original 
function in a child theme.
probably to get different functionality. So why do you need the 
original function?


Just create your action.php and define the same function.


// include '../sometheme/functions/actions.php';

function foo($arg_1, $arg_2, /* ..., */ $arg_n) {
echo "All my new code.\n";
}

It's code duplication. But i don't think themes should have 
dependencies to one an other.

You could also create a actions.php file outside the themes folder.

wp-content/shared-functions/action.php

And then in your themes do:

theme 1

include "shared-function/action.php";

foo();


theme 2

include "shared-function/action.php";

foo();

OK, thanks, Thijs and Peter, it looks like I'm trying to do something
that is not currently possible in PHP. Time for some lateral thinking.

That's not going to happen. My point was you could check in the original

The function is definitely already defined, I just need to replace it

You can check with function_exists to see if a function is already defined.

yeah,

$page = file_get_contents($url);

if you have the appropriate wrapper installed (http) in this case the html
will appear in $page.  you will also need to have enabled the
allow_url_fopen ini setting.

yeah, all a proxy does is act on behalf of something.  so for example i ask
for a web page directly, the web page returns to me unaltered.  i ask a
proxy for a web page, it may return an older version of the page which has
been cached to boost performance, or perhaps, as in your case, a derivative
of the original page.

Any examples or urls to make a fopen wrapper? Or is there a simple

Thats all I really need, if I can get ... in text, I'm

From that point I can insert the text into a hidden form field and

Re: [PHP] include html

I need to basically grab the source of the page as text. Then I can do  
a replace() on the  tag. Then insert the text into an Iframe. In  
theory, this I thought would be handled better server side. Is this  
possible? I think the problem I'm having is that the domain I'm  
requesting from is not the same domain as mine so their may be some  
security issue. I also thought about injecting a link tag into the  
iframe at the same time I load the HTML. Browsers load the last style  
sheet on top of others.  If I could just get the link tag into the  
iframes contents right after I get the source text in there, it may  
work. But there is also the issue of correctly assigning the classes  
and I'd that are used in the iframe. Like


iframe.holder .someclassusedbythem {}

Or do I do?

iframe#holder .someclassusedbythem {}

Or

#holder .someclassusedbythem {}

Sorry if I'm OT with that.

Karl,

this could be done server or client side, however the trouble is
altering the css for every page inside the iframe could be a real
pain.  basically what you could do is act as a proxy, each 'page' from
the original site should be 'made a page' on your site.  basically
youll have to change anchor tag href attributes so each request that
would go back to the original site goes through your site first.  that
way youll have the chance to change the result before handing it back
to the client.  also youll obviously need to change the url to css
file(s) per your primary requirement.  if you do as i suggested above
and make the remote site appear as being served from your domain, you
should be able to get away w/ using a css file served from your domain
as well.

as one of my college professors used to say however, the devil is in
the details, mwahaha.  i would recommend initially experimening to see
if you can use w/e look & feel customizations the remote site offers
to determine if embedding in the iframe w/o any proxy effort is
possible.

Hello,
I am looking for a solution to inject some dynamic html into an  
iframe and rework the css from the results.
Is there a way to do this in PHP? I am not talking about just using  
the src attribute of the iframe either.

Basically,
I want to call on a web page, grab the html code, replace the   
tag with my own and insert it into an iframe on my page.

I am sure this is not as complicated as I am making it, but I have  
been trying with Ajax for the past couple of days and no luck.
So I was wondering if there was a php alternative to do this with. Or  
if it is even possible or ok to do so.

You would probably be better served with changing the include_once to
require_once.

If there is a dependency, then using require will enforce it. E_FATAL

It should be available. Can you show the code you're using? Is the first
include being called within some form of if statement? That might
explain why it's not available when you expect it.

Hello,
I've got a page that uses include_once to include a set of functions
for use in that page. I later have another include_once pulling in
another page, which generates a table. It relies on a function from
the first file, yet an error is being generated undefined function, I
thought that since the function was included in the main page, and
that since the table file was also being included in the main page
that the functions would also be available to the table file. Is this
not so?

Oh! Nice!

[[

The speed of eval
Besides security concerns eval also has the problem of being
incredibly slow. In my testing on PHP 4.3.10 its 10 times slower then
normal code and 28 times slower on PHP 5.1 beta1. This means if you
have to use eval, you should avoid using it inline in any performance
sensitive code. Any easy way to cancel the performance penality is to
create a function in eval and just call that, now an extra function
call does have some performance overhead but its pretty small and
depending on the design can be non-existant since you would be calling
some function anyway.

]]

Interesting. Great read. Thanks for linkage.

[ot] The article also mentions variable functions... I have never used
those before. They look very useful, esp. for a function callback.
Learn something new every day! :) [/ot]

Thanks again for you help Michiel! I really appreciate it. :)

One thing to keep in mind is that this one doesn't take eval() vs regular
include execution time into account, in case you were still considering
using it. According to this page, it's many times slower:

Thanks for the reply Michiel, I really appreciate it. :)

For some benchmarks on the different types of inclusion
functions/language constructs, this page has some good info:



The results are interesting.

Thanks again! Have an excellent day.

I would prefer to use include() since it runs the code in the same context,
and using both file_get_contents() and eval() is a bit of a detour. eval()
also tends to be a lot slower than included code (though I'm not exactly
sure how slow).

I'm also not entirely sure whether file_get_contents() is slower than
readfile(), but file_get_contents() is useful if you want to do something
with your data rather than printing it right away.

Very good points. My goal was to write a plugin that would allow me to
include some static HTML template file and get the 
tags out of my CMS template. With that said, I think the only people
using this code will be the developers of the templates, and not your
standard user.

I opted to use output buffering and readfile() for the speed, and
include() would be an option if developers want to execute the code in
the included file.

Would file_get_contents() be faster than readfile and output
buffering? Would using file_get_conents() and eval() be faster than
using include() and output buffering?

Without boring you all to death, I am mostly interested in learning
new stuff! I actually don't think anyone will use this code other than
myself. :D

But I definitely agree with all your points.

Thanks so much for you help!

Have a great day!

Micky

Hi,

It depends. What's exactly do you want to prevent? It doesn't seem like a
very big problem if someone tries to include an improper adderss or
nonexistent file, since that would simply make $data an empty string
(depending on your level of error reporting and whether you display or hide
warnings). If the included file decides to call ob_get_clean() or something
like that $data will be false. I can't think of what else you realistically
want to prevent.

Building a page with multiple templates is best done by using a good
template class. Allowing the inclusion of external PHP files from a CMS will
pose a risk if non-developers have access to the CMS as well. You're
basically allowing anyone to add (potentially untested) code to a live site
and I would recommend against doing it. If you want people to be able to
include, say, additional HTML content, use file_get_contents() instead.

[PHP] PHP include security

[Micky Hulse]

Hi,

Code:

=

ob_start();
switch ($this->command)
{
case 'include':
@include($x);
break;
default:
@readfile($x);
}
$data = ob_get_contents();
ob_end_clean();

=

The above code snippet is used in a class which would allow developers
(of a specific CMS) to include files without having to put php include
tags on the template view.

The include path will be using the server root path, and the include
files will probably be stored above the web root.

My question:

What would be the best way to "clean" and secure the include string?

Maybe something along these lines (untested):

$invalidChars=array(".","\\","\"",";"); // things to remove.
$include_file = strtok($include_file,'?'); // No need for query string.
$include_file=str_replace($invalidChars,"",$include_file);

What about checking to make sure the include path is root relative,
vs. http://...?

What do ya'll think? Any suggestions?

Many thanks in advance!

Micky

Hi,

I'm not sure why the virtual server settings are being ignored in the

Forgot to mention a few things, if your app is sophisticated enough to require 
header settings (content-type, etc), those include have to go before the 
buffered output is sent.  Also, you want to make use of chunked encoding, you 
cannot use/specify content-length in the header.

Depends on your application design and/or your desired result.  If you design 
your application to do all processing before output is sent starting with 
, then all your includes goes before .  If you want to have the 
modular approach of including css & js files inside the  element, you 
don't have to worry about going back to changing every single output file when 
you decide the change your layout or javascript framework.  It also makes your 
code page a bit cleaner when you do use include in the .  If you want to

[PHP] Include Paths

[Julian Muscat Doublesin]

I had a problem with the include and require paths when using AJAX. This I
have solved by using the document root. However since doing so I am
experiencing performance issues. Loading 20 records has suddenly turned into
something of a matter of a minute rather then seconds.

Has anyone ever experienced such an issue?

Can anyone please advise?

Another way off the top of my head:

//vars.php
$vars['something'] = 'hi';
$vars['whatever'] = 'bye';

//test.php
class CSomeClass {
 var $vars;
 public function cinclude() {
   include('vars.php');
   $this->vars = $vars;
 }
}

$object = new CSomeClass;
$object->cinclude();
echo $object->vars['something'];//i want this to print 'hi'

Hello,

I've cleaned up my question a bit.

I want the included file which is called within a method of a class to
have the same scope as the instantiation of the class's object.  That
is, i want a class to include a file in the calling object's scope.  How
would one do this?

'test.php'
cinclude();
echo $vars;//i want this to print 'hi'
include('vars.php');
echo "obvious $vars";
?>

'vars.php'


OUTPUT:
Notice: Undefined variable: vars in ...\test.php on line 10
obvious hi

DESIRED OUTPUT:
hi
obvious hi

replace all $var with $vars.  The extract method proposed is the
opposite of what i'm looking to do.  I want to bring the class's include
scope into the calling object's scope.

[PHP] include file in a class with global/parent scope?

[Daniel Kolbo]

Hello,

I understand the why $vars is not in the global scope, but i was
wondering if there was a way from within the class file to include a
file in the parent's scope?

i tried ::include('vars.php'), parent::include('vars.php'), but this
breaks syntax...

Please consider the following three files:

'scope.class.inc'


'vars.php'


'scope.php'
cinclude('vars.php');
echo "In original $vars\n";//$vars is not defined***
?>

Thanks,

[PHP] include file syntax

[PJ]

How does one deal with tag completion from an include file to the
main(source)-file?
i.e. c should a tag, such as  or  be closed withing the
include file? Or can  be started in the include file and closed in
the main-file?
Crossing the border, so-to-speak, doesn't seem to matter; but how does
this affect validation and execution?
Anyone have a clarification, please?

This is one detail that I have not seen a good explanation for. When PHP
opens an included file, it defaults back to HTML mode. You must have the
PHP tags to force it into PHP mode. This is true no matter what file
extension you have on them. So if you want to use PHP style comments,
you must wrap them with the proper tags.

If you're putting php comments outside php tags, they are treated as 
text (they're not inside php tags, it's not php).


The php tags tell php when to start parsing/processing the script. 
Without that, it passes it to your webserver to just display the content.


If that's not what you're doing post a short (very short - don't post 
your whole scripts) example of what you mean.

Yes. If you use a php comment it has to be inside a php tag.

One issue I have seen though is xml/xhtml files.
php sometimes sees the I assume the appropriate thing to do is turn off short tags in your 
php.ini file - but unfortunately a lot of 3rd party classes and apps 
make heavy use of them.

Use html comments and it should be fine - or put php tags around the 
comments.

[PHP] Include File Errors with Comments

I have a simple web site with a simple page that all works well, 
although I have had a similar problem a couple of times that seems to be 
caused by Comment Lines in the included files. I wonder if I have it 
entirely right.

All my files are .php files, but almost all the code is HTML.
The file for my Web page is a complete HTML document, the file is .php. 
The web page file "Includes" a few other files by putting the Include 
statement in PHP tags, all by itself. The problem file contains the menu 
as the include. I made a change to the menu, that works, but I added a 
line with a comment at the top, which causes problems. The menu is read

2 comment lines, the failed with 3 lines. Even when it fails the

that's the way i do it, for example

require_once realpath( dirname(__FILE__) . '/lib/LibAllTests.php' );

also I often use set_include_path to ensure everything works throughout, 
it's a lot simpler for require/includes


set_include_path( get_include_path() . PATH_SEPARATOR . realpath( 
dirname(__FILE__) . DIRECTORY_SEPARATOR ) );


for example.. then all subsequent requires will be:

require_once 'Folder/file.php';

Sorry, guys, but none of this works...
I get the document root which is wonderful but it misses the vhost root
completely.
So what I get both with realpath and $SERVER['DOCUMENT_ROOT']is
/usr/local/www/apache22/data/images/file.gif or
/usr/local/www/apache22/data/../images/file.gif
and that, of course misses the main directory for this site which is
ptahhotep

In /ptahhotep/file.php - the path for the image.gif is images/image.gif
In /ptahhotep/admin/another_file.php/ the path  for the image.gif is
../images/image.gif

But as I try different variations, I finally see that adding the root
directory name for the site does the trick.

Have I discovered something new here? :-)

5.) dirname() gives you the full path on disk, not the URL. Usually you can
just remove the document root path to get the URL. This could be in
$_SERVER['DOCUMENT_ROOT'] but you can't rely on that between servers or when
the config changes.

It is when it's parsed by PHP.  You're just putting it through as
straight HTML, which - even though it may have a .php extension -
won't work as you might be expecting.

Instead, you have to instruct the parsing engine where and when to
interpret, compile, and execute the code, like so:



In the above snippet, notice a few very important things:

1.) We use regular open tags to be compatible with all stock
PHP configurations.
2.) We echo out the response from dirname() so that it's
output to the HTML source.
3.) We use dirname() twice, so it gives the dirname() of the
dirname(), rather than '..'.
4.) There are double underscores around FILE.  The same is
true with LINE, FUNCTION, etc.

[PHP] include question

[PJ]

good morning all,

How can I include src and href in include files that will refer the
right paths from files in different hierarchies(directory tree levels)?
Example:
include dirname(_FILE_)."/../lib/header1.php"; ?

This does not work:
snippetysnip...


Nor does this: (NOTE THE DIFFERENCES " AND ' IN THE SRC AND HREF)

.htaccess won't call it since it isn't actually executed, but you can
set up an auto_prepend_file in .htaccess that will be automatically
prepended to all your PHP scripts in the folder (assuming the server
config allows it).

Taking in what everybody else has already pointed out, I would like to add that 
their is a php configuration option that will do something along the
line of what you are trying to do.

It is called the 'auto_prepend_file' option.

You could do something like this in your httpd.conf file instead of what you 
are trying to do.



... All Your normal stuff ...

php_value auto_prepend_file '/path/to/file.php'



The above code will include your php file as a standard php include every time 
someone visits the given VirtualHost block.

Hope this helps.

You get this error because you are trying to include a php file in the
apache configuration. Apache config files have tags, such as  and
 ... 

If you want to include php scripts in your php file, you should do that
there, e.g. in incfiles.php:
http://nz2.php.net/autoload ).
