1. if $categoriesIN comes from a POST, use $_POST['categoriesIN'] instead.
It does, but results are the same. Maybe it has something to do with
SESSIONS.
better yet use the filter extension (part of the core) to retrieve the
input.
2. validate santize your input (the reason to use the filter extension)
I imagine it is duplicate work but since I am learning and want to
concentrate on 1 thing at a time, I am leaving the sanitizing part as
the lest task before validating the whole script (page).
3. WHY do you want to extract the values and assign them to vars?
shows you I don't know what i'm doing...
Her is what finally worked and that's where I learned that the values
are saved as arrays. =-O
$autoId = mysql_insert_id($result);// this was recovered earlier in page
foreach($categoriesIN as $category){
print $categorybr /;
$insert_category = INSERT INTO book_categories (book_id, categories_id)
VALUES ($autoid, $category);
mysql_query($insert_category,$db);
}
Here's the problem...
the values saved interesect the book_variables with variables and books.
I believe the variabless are saved as arrays (1 entry per fiels -e.g.
there are 4 categories for 1 book) I have to recover the names of the
categories (field category in categories table) and display them in an
HTML table with hrefs to the correesponding pages. What I am trying to
figure out is how to select and echo the categories for each book.
here is part of the select statement concerning the categories:
(the rest of the select works, but since there are several categories,
my table shows several entries for 1 book that has several categories)
snip...
LEFT JOIN book_publisher as abc ON b.id = abc.bookID
LEFT JOIN publishers AS c ON abc.publishers_id = c.id
LEFT JOIN book_categories AS d ON b.id = d.book_id
LEFT JOIN categories AS e ON d.categories_id = e.id
ORDER BY title ASC ;
I suppose that
LEFT JOIN categories AS e ON d.categories_id = e.id
needs some qualifier that will output the categories as
cat1, cat2, cat3, cat4... for count($rows)... or something like that; in
other words, as 1 row instead of 1 row per category.
Hope I'm not too confusing.
since you don't know the number of entries there is no point in creating
a stack of variables of which you have no idea what they are even called
or how many there are. instead loop the array or use an index into the
array to find the data your looking for. you don't have to create a
specific variable to use a piece of data the given element of an array
is just as valid.
4. there is the extract() function ... use at your own risk.
5. do something like this:
foreach ($array as $key = $val)
$$key = $val;
.. again use at your own risk.
echo $categorybr;
}
or
if(!empty($_POST['categoriesIN'])){
foreach( $_POST['categoriesIN'] as $key = $value) {
echo value = $valuebr;
}
both show the values entered in the form but do not create a variable.
Since the number of entries will vary, I cannot assign a number of
variable names before knowing how many entries there may be.
After I sent that last email a few hours ago, I started thinking that you were
using a JOIN in your SQL.
Since you were complaining that you were getting duplicate entries for each book that had more then one category
assigned to it.
The problem is with the JOIN.
What you need to do it execute 1 SQL call to the books table and 1 call to the
book_categories table.
All the following code it typed directly into my email client. It is
completely untested.
Hopefully it works for you.
?php
# Do your db setup...
$dblink = mysql_connect(.);
# call to your books table (without a join to the books_categories table)
$SQL = SELECT id, title, author, etc... FROM books ORDER BY author, title LIMIT
10;
$books = array();
if ( ( $results = mysql_query($SQL, $dblink) ) !== false ) {
# loop through results, place in array.
while ( $row = mysql_fetch_assoc($results, $dblink) ) {
$books[] = $row;
}
# we must have one book, otherwise this will return false and we would
not need to call for other information
if ( $books ) {
$book_categories = array();
# call to your books_categories table
# ( do an ORDER BY in your SQL so the categories always show up
in the same order)
$SQL = SELECT book_id, cat_id FROM books_categories ORDER BY
category;
# loop through results, place in array
if ( ( $results = mysql_query($SQL, $dblink) ) !== false ) {
while ( $row = mysql_fetch_assoc($results) ) {
$book_categories[$row['book_id']][] =
$row['cat_id'];

I want to index the files on a website recursively. The program will
run
in
the site root
directory, which GETCWD reports as D:/Websites/Website_1. I can open
any
file in the root
directory simply using its file name; Joe.dat, for example, and I can
opendir for any
subdirectory; eg
opendir(Subdirectory_1);
but opendir () does not seem to work, and the only way I can find to
open
the root
directory is to give its full path; eg
opendir (D:/Websites/Website_1);
I have got the program working by using the full path to open the
root
directory, and then
using relative paths to open the subdirectories and individual files,
but
this seems
rather a kludge, and I am wondering if there is a way to open the
root
directory without
specifying an absolute path?
The current working directory cannot be trusted to be right. The best
option is to use dirname(__FILE__) and add '/..' as many times as
needed
to
get from the current file to the document root you're after.
It has always worked for me. But then I never change directory. But
both
give a hardware
dependent answer;
echo 'pCurrent directory is '.__FILE__.', CWD is '.getcwd().'/p';
gives
Current directory is D:\Websites\Corybas\Cydaldev\Dev\Testbed_2.php, CWD
is
D:\Websites\Corybas.
Not sure what you mean by a hardware-dependent answer. The current working
directory for any given script is determined by the web server and so it
cannot be assumed to be the location of the current script.
dirname(__FILE__) will give you the directory the current script is in.
I agree that 'hardware dependent' was not the right word, but what I meant
was that if I
am running the local version of my program getcwd() will return
'D:\Websites\Corybas',
where as if I am running the remote version it will return
'home/Corybasftp/www'.
This should be irrelevant in your code, something you can achieve using
dirname(__FILE__).
My webpage is always launched by loading index.php from the root directory,
and I don't
think I ever change the working directory, so although the code actually
being executed at
any given time is usually in a subdirectory, getcwd() will reliably return
the (system
dependent) long definition of the root directory.
Either I'm not explaining this well enough or you're just not getting it.
Ignore the current working directory - it's not reliable. If every page is
created by a single script then the solution is to define a constant at the
top of that script that gives you the directory that script is in
define('ROOT_DIR', dirname(__FILE__));
Then when you need to refer to another file in your directory structure you
do so relative to the location of index.php. So if you have a directory
named arse in the same folder as index.php you'd refer to that like so...
ROOT_DIR.'/arse'
If that's not clear maybe this will help:
http://dev.stut.net/php/dirname.php
Based on that the following should work in your particular situation, but
rather than just using this I encourage you to understand why it works...
opendir(dirname(__FILE__).'/../Cydaldev');
Looking into this I did find that 'opendir('Albums/../');', where 'Albums'
can be any
subdirectory I know to be present, will reliably open the root directory.
You clearly haven't looked into this at all since you're still not using
dirname(__FILE__), and if this email complete with the example script above
doesn't get the point across I give up. Have you even looked up dirname in
the manual? http://php.net/dirname
As a result of what seems to me to be an oversight in the design of
opendir(), in that
opendir(Fred) and opendir(Fred/Nurg) will open the appropriate sub
directories but
opendir() will not open the root directory, I can readily index all the
subdirectories by
giving their relative paths, but I have to resort to a kludge to index the
root directory,
and another kludge to eliminate this kludge from the index.
As in the example script I've posted above you can refer to the current
working directory with a single period (.), but this is still relying on the
current working directory being what you expect it to be.
If, as it seems, I have to accept this it is fairly immaterial which kludge
I actually
use.
There is no need to use a kludge. I encourage you to read my replies
carefully if you're still not getting it.

[PHP] Line Break Problem
Hi, I have a question regarding using line breaks in PHP. I have the code something like: echo 1 . \t . $x . \t . $y . \r\n; When I run the code, it looks like a whole blob of text, but when I use View Source, the line breaks are formatted then correctly. Anyone can please tell me if this is what this is supposed to be? If so, how can I get the user to see the line break as they are, do I have to use br? Thanks for your help.

Re: [PHP] Retrieving Image Location in PHP from MySQL
Hi Nathan,
Thanks a lot for the suggestion. It is working fine for an example code
I have used to test it. The code I have written after your suggestion is
as follows.
?php
$location=C:\wamp\bin\apache\apache2.2.8\htdocs\Bldgs_lots\SQUIRES.jpg;
header('Content-Type: image/jpeg');
imagejpeg(imagecreatefromjpeg($location));
?
The above code is yielding me a picture. Now, When I tried to use it in
my original code it is not giving me the image. Instead it is giving me
this warning *Warning*: Cannot modify header information - headers
already sent by (output started at C:\wamp\www\mysqli.php:65) in
*C:\wamp\www\mysqli.php* on line *221*
and a lot binary characters again instead of the image. I know something
about this warning that we should not output anything to the browser
before the header. But I cannot do that, since I need the user input
using a html form and I use the input to fetch the data and dispaly it
in a table along with the image. I am posting the whole code below.
Please do let me know about any changes, corrections or modifications
that are needed. The image display code is towards the last.

Hi Tom,
Not XSLFO as such, this was split up years ago in to it's comprising
parts - XSLT, XSL and XPath, all of which PHP supports with the
fantastic addition of a full DOM API for XML based documents.
http://php.net/dom (includes DOMXPath)
http://php.net/xsl (XSLTProcessor)
example:
?php
// load xsl
$XSLDocument = new DOMDocument();
$XSLDocument-load(xsl_document.xsl);
// load xml
$XMLDocument = new DOMDocument();
$XMLDocument-load('xml_document.xml');
//run xslt transformation
$XSLTProcessor = new XSLTProcessor();
$XSLTProcessor-importStylesheet($XSLDocument);
$NEWDoc = $XSLTProcessor-transformToDoc($XMLDocument);

I have included the publisher stuff - it works, whereas the category
stuff does not...
Surely if it is your table, you already know what types of data each
field contains?
I did and do.. I just was not getting the output I was expecting...so I
panicked and looked for ways to verify all... bit, by bit I went over
all my little lessons of the past weeks and ... of course, taking my
sweet time and lack of knowledge it took me a while to figure out that
the problem was a missing SELECT table.column from the query. When I
found the error, everything fell into place.
But there remains the problem of how to select and display several
categories from the query. If there isi only one category, there is no
problem; with more than one I can't figure out how to retrieve it
without the output showing as many entries for the same book as there
are categories. Everything is output (echoed) correctly but the books
are echoed in their entirety along with the category... what could I
post to analyse the prolem. I'm sure it's something simple, like
imploding the array so it isn't repeated... ??
I think you'll probably have to use an ORDER BY clause in your query,
and only output a new book name when it changes during iteration. For
instance:
1. grab book categories (book id, book name, category id, category
name) with a JOIN
2. set last book name to (empty string)
3. for each row in the result set
3a. if book name is different than last book name, output it
3b. output category
3c. next

I want to index the files on a website recursively. The program will

in
the site root
directory, which GETCWD reports as D:/Websites/Website_1. I can open
any
file in the root
directory simply using its file name; Joe.dat, for example, and I can
opendir for any
subdirectory; eg
opendir(Subdirectory_1);
but opendir () does not seem to work, and the only way I can find to
open
the root
directory is to give its full path; eg
opendir (D:/Websites/Website_1);
I have got the program working by using the full path to open the
root
directory, and then
using relative paths to open the subdirectories and individual files,
but
this seems
rather a kludge, and I am wondering if there is a way to open the
root
directory without
specifying an absolute path?
The current working directory cannot be trusted to be right. The best
option is to use dirname(__FILE__) and add '/..' as many times as
needed
to
get from the current file to the document root you're after.
It has always worked for me. But then I never change directory. But
both
give a hardware
dependent answer;
echo 'pCurrent directory is '.__FILE__.', CWD is '.getcwd().'/p';
gives
Current directory is D:\Websites\Corybas\Cydaldev\Dev\Testbed_2.php, CWD
is
D:\Websites\Corybas.
Not sure what you mean by a hardware-dependent answer. The current working
directory for any given script is determined by the web server and so it
cannot be assumed to be the location of the current script.
dirname(__FILE__) will give you the directory the current script is in.
I agree that 'hardware dependent' was not the right word, but what I meant
was that if I
am running the local version of my program getcwd() will return
'D:\Websites\Corybas',
where as if I am running the remote version it will return
'home/Corybasftp/www'.
This should be irrelevant in your code, something you can achieve using
dirname(__FILE__).
My webpage is always launched by loading index.php from the root directory,
and I don't
think I ever change the working directory, so although the code actually
being executed at
any given time is usually in a subdirectory, getcwd() will reliably return
the (system
dependent) long definition of the root directory.
Either I'm not explaining this well enough or you're just not getting it.
Ignore the current working directory - it's not reliable. If every page is
created by a single script then the solution is to define a constant at the
top of that script that gives you the directory that script is in
define('ROOT_DIR', dirname(__FILE__));
Then when you need to refer to another file in your directory structure you
do so relative to the location of index.php. So if you have a directory
named arse in the same folder as index.php you'd refer to that like so...
ROOT_DIR.'/arse'
If that's not clear maybe this will help:
http://dev.stut.net/php/dirname.php
Based on that the following should work in your particular situation, but
rather than just using this I encourage you to understand why it works...
opendir(dirname(__FILE__).'/../Cydaldev');
Looking into this I did find that 'opendir('Albums/../');', where 'Albums'
can be any
subdirectory I know to be present, will reliably open the root directory.
You clearly haven't looked into this at all since you're still not using
dirname(__FILE__), and if this email complete with the example script above
doesn't get the point across I give up. Have you even looked up dirname in
the manual? http://php.net/dirname
As a result of what seems to me to be an oversight in the design of
opendir(), in that
opendir(Fred) and opendir(Fred/Nurg) will open the appropriate sub
directories but
opendir() will not open the root directory, I can readily index all the
subdirectories by
giving their relative paths, but I have to resort to a kludge to index the
root directory,
and another kludge to eliminate this kludge from the index.
As in the example script I've posted above you can refer to the current
working directory with a single period (.), but this is still relying on the
current working directory being what you expect it to be.
If, as it seems, I have to accept this it is fairly immaterial which kludge
I actually
use.
There is no need to use a kludge. I encourage you to read my replies
carefully if you're still not getting it.

lol stut! - just-in-case I'll add in that __FILE__ is a magic php
constant holding the path to the file it is used in, and not just
stuarts way of saying put your filename here

The same as you would in accessing channels 0, 1, and 2. The

print_r($ret); // Now contains a combination of STDOUT STDOPT

Or you redirect STDOPT output to a file:

print_r($ret); // STDOUT (Channel 1)
print_r($err); // STDERR (Channel 2)

I tried /dev/fd/3 and failed to open it...
Got no error messages about why it failed to open, it just failed.
Am I missing something?
Make sure you have 'udev' installed on there, and also be sure
that /dev/fd exists, and /dev/fd/3 exists. Also make sure that, when
you're checking it, STDERR isn't already being redirected somewhere
else, and that you're not missing some bad file descriptor errors in
the mix.

opendir(), in that
opendir(Fred) and opendir(Fred/Nurg) will open the appropriate sub
directories but
opendir() will not open the root directory, I can readily index all the
subdirectories by
giving their relative paths, but I have to resort to a kludge to index the
root directory,
and another kludge to eliminate this kludge from the index.
As in the example script I've posted above you can refer to the current
working directory with a single period (.), but this is still relying on the
current working directory being what you expect it to be.
If, as it seems, I have to accept this it is fairly immaterial which kludge
I actually
use.
There is no need to use a kludge. I encourage you to read my replies
carefully if you're still not getting it.

Hi Clancy,
I think you want to traverse all files in a directory and its sub directories.
Here is a link to scandir() a php function for reading files and sub
directories of the target directory in your case the root web folder.
It has examples and explanations on how it works.

Re: [PHP] web refreshing problem
Hi,
my php program does not display current result of submitted form
instead the previous content is shown until you refresh manually
(which means resubmitting the form).
Can someone help me out because, I want to display the result of the
latest form result and not the old one.
I am using apache server on windows. Please help.
have you per chance got all data saved in the session and are using a script
like
if( something in session ) {
show session
}
else if( something in post ) {
add form data to session
}
else {
show only the form
}
three common causes are:
1- you're not actually processing the new form data
2- your browser isn't sending the form data second time round
3- your browser is caching the page (very very unlikely)
regards
Hi Nathan,
Most likely your form is using POST method and your browser is
caching the page.

Re: [PHP] Retrieving Image Location in PHP from MySQL
Hi,
Yes, the problem was solved, but It did not work fine when I used the
same code in my larger file. Now it makes sense. Let me just repeat what
you have said just to make sure that I did not misread you.
So you say that the solution to this problem is to create another php
file with the image fetching header and just write an img tag img
src=myimagescript.php?id=1234 / in my original php file (with the
html tags). This is what I have understood.
Regarding the point you have mentioned ( If you set the content type
using header() to image/jpeg, do not use HTML tags to display your
image!), I definitely need the HTML tags, because this application works
based on the user input. So unless there is not input through a html
form, it wont work.
Thanks,
Sashi

Re: [PHP] Retrieving Image Location in PHP from MySQL
I am using a WAMP server for my coding purposes. My MySQL Version is
5.0.51b, PHP version is 5.2.6 and Apache version is 2.2.8
I have created a database with one of the tables containing a location of
the image. Using PHP I am trying to retrieve the location of the image (from
the mysql db) and display it in a browser. I have, with help from php-db
mailing list user's help, created a code to do the same. Now, the problem
is, the code is extracting the location details of the image exactly and it
is even getting the image details. But it is simply not dispalying the
image. Instead of displaying the image, it is printing a hell lot of binary
characters (For example: 2!

I have tried in two forums and mailing lists but none of them have
completely answered my question. How do I get rid of these signs and display
the original image in its place? And to display the image successfully, is
it really necessary to create the image retrieval and displaying code in a
seperate PHP file? Any PHP gurus, enthusiasts, newbies out there, Please
help me out.
I am posting the code below so that you can directly see what I have done
till now. The name of the php file is mysqli.php. The location of the image
is stored to the variable $location. The image retrieval code is present
towards end of the file.

Re: [PHP] web refreshing problem
my php program does not display current result of submitted form
instead the previous content is shown until you refresh manually
(which means resubmitting the form).
Can someone help me out because, I want to display the result of the
latest form result and not the old one.
I am using apache server on windows. Please help.
have you per chance got all data saved in the session and are using a
script
like
if( something in session ) {
show session
}
else if( something in post ) {
add form data to session
}
else {
show only the form
}
three common causes are:
1- you're not actually processing the new form data
2- your browser isn't sending the form data second time round
3- your browser is caching the page (very very unlikely)
regards
Hi Nathan,
Most likely your form is using POST method and your browser is
caching the page.
yes my form is using post method but how do you stop catching the page
hi Andrew,
use the code below. it is from this page
http://www.php.net/header
look for Example #2 Caching directives.
?php
header(Cache-Control: no-cache, must-revalidate); // HTTP/1.1
header(Expires: Sat, 26 Jul 1997 05:00:00 GMT); // Date in the past
?
to be sure, put them as the first 2 lines at the top.

Perhaps I should have phrased it a bit more concise: This has been discussed many times--often, and RECENTLY. Anyway, since I'm already writing this, I'll say that overhead/bloat vs. productivity of the developer is a trade-off you're going to have to make for ANY of the frameworks out there. hi, all php frameworks have overheads which you don't have to worry about. those overhead codes are there to make things easy for you so you can focus on building your application. for me, the most important factor in choosing the right php framework is the size of its community. the bigger the better because there will be more people to exchange ideas with.

I don't do it often, but one site I made a while ago was based on a standard main page with the content included in. The content pages then had absolutely nothing except the unique text, so that redesigns to the site were made easier in the futurem, because only one page needed to be edited. So the entire site was based around a page.php?ID=x with the ID specifying the include required. Such as an example might be a little out of date now, what with CSS and so forth, but it was useful at the time.

Even the core section of each page is included from the initial file. That way we can change the appearance, or modify the links to our disclaimers and help files just once and every page gets updated. We also have configuration flags to prevent some of those files from being included in a specific virtual domain, so our clients can provide their own templates instead of using ours. File extensions for includes are up to you. Just make sure your IDE/Editor know that they are PHP files. We use .lia for the libraries of functions we use throughout the site.

You can start off by checking the input fields and if they are empty, simply display the form. Then the next time through, when the fields are populated, insert the selected image.

can read the page if it is made completely on includes?
Any and all comments would be appreciated.
Gary
Hi Gary,
I think this thread is at risk of getting confusing and not addressing
the problem at its root.
An include is typically used to allow storing reusable code in a file
all by itself, this could be a settings (config) file, a class, an html
template or whatever - purpose being of course to keep you all nice and
organised, with each thing in its place.
Leaving out everything else and focusing only on why we'd use
include/require in an application, let's take a simple example:
Simple PHP Site with 3 Pages.
1 - / (the homepage)
2 - /?page=about (the about us page)
3 - /?page=contact (the contact us page)
in the above scenario then your index.php could look like this
?php
//set the default page to be home
$page = 'home';
//check if a page has been specified
if( isset($_GET['page']) ) {
$page = $_GET['page'];
}
if( $page == 'home' )
{
include 'home.php';
}
elseif ( $page == 'about' )
{
include 'about.php';
}
else( $page == 'contact' )
{
include 'contact.php';
}
else
{
include 'page-not-found.php';
}
?
very simple, but works; now let's expand it a bit.. in a real world
scenario we probably have a good chunk of script at the top of index.php
that holds database settings, database connection etc. and in each of
our pages we probably have much of the html repeated (site header,
footer, navigation) - we can then abstract these in to there own files
to keep it all nice and clean.. as such
?php
$page = 'home';
if( isset($_GET['page']) ) {
$page = $_GET['page'];
}
// get site database settings
require 'config.php';
// get our database class
require 'classes/class.database.php';
// start out database
$database = new DatabaseClass($settings_from_config);
// load the site header
include 'templates/header.php';
// load the content for the requested page
if( $page == 'home' )
{
include 'content/home.php';
}
elseif ( $page == 'about' )
{
include 'content/about.php';
}
else( $page == 'contact' )
{
include 'content/contact.php';
}
else
{
include 'content/page-not-found.php';
}
// load the site footer
include 'templates/footer.php';
?
now everything is in its rightful place and we have lots of easy files
to work with, for example now you can let a designer work on the
about.php page knowing that they won't be able to break the whole
application, as it's just a bit of html content.
also, you can now change the header image in one file
(templates/header.php) and the whole site will update.
most PHP websites are simply far more complex versions of the above,
look complicated but the principals are the same.
now the only thing I didn't cover is which to use.. it's often the case
that require_once and include_once should be used over include and
require; because in most cases (certainly with classes) you just want to
ensure the code is available. both of the _once statements will only
load the file if it hasn't been already, thus ensuring no errors such as
class already defined because it's already been included!
On the other hand if the code in the file has been designed to be used
many times on a page then include would be the better choice - a
really stupid example but consider a file containing a fancy horizontal
bar; you may want to include this many times on a page.
Finally, require and require_once will kill the script with an error if
the file isn't found, whereas include will throw an error and simply
keep on going if the files isn't found.
Think that covers everything in the scope of this :)
Regards!
Nathan

I discovered that error and warning messages from my program does not

have you per chance got all data saved in the session and are

like
if( something in session ) {

else if( something in post ) {
add form data to session

three common causes are:
1- you're not actually processing the new form data
2- your browser isn't sending the form data second time round
3- your browser is caching the page (very very unlikely)

Hi Nathan,
Most likely your form is using POST method and your browser is
caching the page.
yes my form is using post method but how do you stop catching the page
hi Andrew,
use the code below. it is from this page
http://www.php.net/header
look for Example #2 Caching directives.
?php
header(Cache-Control: no-cache, must-revalidate); // HTTP/1.1

to be sure, put them as the first 2 lines at the top.

J I agree with you're disagreement, a good framework will indeed reduce code bloat. fork post prong 1: *jumps on* the MVC thing, you can't just say mvc is the appropriate architecture for php applications; true many the frameworks follow the whole pythonesque MVC thing; but that doesn't make it any more the correct choice than any other architecture or design pattern. There is no fits all and all too often you see people trying to overstretch there framework of choice to something it just doesn't do and wasn't designed for (not as common as trying to fit drupal in a square hole though :p) prong 2: However IMHO there are other benefits which outweigh this: - multi other developers will be familiar with the codebase and be able to on board rapidly should the project expand - the client won't be left with some unknown codebase that only you really know (unless of course you want to tie the client in) - you learn well known re-usable code that you can take to other projects (and add to the cv) - bugs in code move from being a headache to an opportunity for improvement and benefit the community (and often fixed by others) - your code base is ever improving without you doing any work - and all the obvious stuff.. prong 3: If you're planning on being the next NY Times, WordPress will not be a kind mistress. - lol, I wish all clients understood this. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

I've recently noticed that when I write a script that they seem to have different permissions when executed at the command line. Two that I have written recently run just fine when you execute 'php scriptname.php' but they are unable, at least, to write the data if I browse to them on localhost. Am I imagining things? If not, how would I properly make them able to run through a browser? Thanks! G

Two that I have written recently run just fine when you execute 'php scriptname.php' but they are unable, at least, to write the data if I browse to them on localhost. Am I imagining things? If not, how would I properly make them able to run through a browser? Thanks! G This is to do with the fact that the web browser runs as a different user from you (usually apache, apache2 or wwwrun) What you could do is make the directory where you want to write files with the script part of a new group. Add the apache user to this group and you should then be able to get it to run.

Re: [PHP] Script execution
Thanks everybody! I guess I was a little vague. I'm working on an OpenSUSE setup with Apache, MySQL and PHP. I just knew that my confusion was because of my Windows up-bringing. The writing I referred to was to a file. One example is I had a script that was pulling data from a database and using it to generate PDF files. This would work fine from the command line but _not_ if I pointed a browser at it. It wasn't an important difference because that script is a cronjob anyway. I just wanted to understand what was going on and how I could change it -- if I find later that I need to. Again, that's for the rapid and thorough help!

As in the example script I've posted above you can refer to the current working directory with a single period (.), but this is still relying on the current working directory being what you expect it to be. Thank you! This is what I had been looking for all along. I dimly remembered some such trick, but it had become lost in the detritus at the back of my mind. But why the obsession with avoiding getcwd()? When my site is loaded the current directory is always the root directory of the page, and as I never change directory I can rely on it staying there. (And, incidentally, since getcwd(), dirname(__FILE__), etc, all return the complete path including system dependent information, if I really didn't know the current directory it would not be a trivial task to determine what was the local root.) For a couple of years I have been using getcwd() to determine whether or not I am running on my local PC (if I am the path will start with 'D:'). If I am running on the local PC I load various editing and other private facilities, otherwise I omit them.
