[PHP] Newbie question: need to transfer directory contents from my local machine to my website
Hi all: I'm really new at PHP and will probably embarrass myself many times over asking questions that have been asked gazillions of times before, so let this serve as a blanket apology. Now, to my question. Here's what I'm trying to do. I have a simple database on my website that I wish to populate with information from various directories on my local computer. The website is running Linux; my computer is running Windows XP. Once the data are stored, I want to be able to update the information as things change on my local computer (not in real time, mind you, but at my request). I can set up the database access easily enough, and I know how to both populate and query it. What I don't know is how to obtain the information from my local computer via the website. Initially, I'd like to be able to specify the folder on my local computer to access and whether or not to process any subfolders that are found. After the data have been added, I'd like the web application to be able to access the individual folders without having to specify them again (although I'd still be able to identify new folders to include in subsequent updates). I'm not really asking for anyone to write the code for me, but I am looking for suggestions for PHP functions to use to accomplish the inspection of my local computer's folders. I'd also need to know what additional information I'd need to store in the database so that subsequent updates can be automated (i.e., do I need to somehow store my IP address?). Any help you can send my way will be greatly appreciated! Thanks in advance. Sincerely, Jon
Re: [PHP] php newbie question with xml files
This should get you started:
$old_data = file_get_contents('./test.txt');
$my_data = foo bar;
$pattern = '/(.*)(\/.*)$/i';
$replacement = '$1' . $my_data . '$2';
$new_data = preg_replace($pattern, $replacement, $old_data);
echo $new_data;
or a little more succinctly
$my_data = foo bar;
$new_data = preg_replace('/(.*)(\/.*)$/i', '$1' . $my_data . '$2',

Subject: [PHP] php newbie question with xml files
I have an xml document storing some data I need. What I want to do is
this:
1. Scan to the end of the file.
2. Find the closing tag.
3. Insert a new entry in before the closing tag.
I've tried:
1. Creating new files and renaming them to be the original.
2. Writing the file to a dummy file and insert my lines part way through
then finish the last tag.
My problem is I'm looking for a /endtag and it comes up as endtag. Is
there anyway to force PHP to read the .xml file as a text file so it wont
strip off the xml tag information?
I've used fopen with fgets and fwrite, and file with fwrite

Re: [PHP] php newbie question with xml files
I have an xml document storing some data I need. What I want to do is this: 1. Scan to the end of the file. 2. Find the closing tag. 3. Insert a new entry in before the closing tag. There are specific classes and functions in the PHP core that can help you do just this. I've tried: 1. Creating new files and renaming them to be the original. 2. Writing the file to a dummy file and insert my lines part way through then finish the last tag. I don't think this is the right approach to take. Maybe using the DOM and/or the XML Parser built-in to php would help you. My problem is I'm looking for a /endtag and it comes up as endtag. Is there anyway to force PHP to read the .xml file as a text file so it wont strip off the xml tag information? I've used fopen with fgets and fwrite, and file with fwrite Again, this isn't the approach to take. There are built-in functions for this sort of thing, as well as classes on PEAR that will help you. Try google! Read through all of this and decide which approach you want to take before you start anything... If you use Windows or compile PHP as an Apache module in Linux, you're all set with the XML Parser. If not, you'll need to get the library according to the directions in the manual. http://www.php.net/xml Read everything in that thoroughly, and understand it before you continue with this approach. Copy and play with the examples to see how it all works. If you'd rather handle things in an environment designed to create and manipulate XML dynamically, rather than just read and insert raw strings, keep reading. You can get the DOM XML working easily in Windows, and even easier in a GNOME environment on a linux box. The manual has excellent instructions. http://www.php.net/domxml This extension is Object-Oriented (OO), and if you don't know what that is, you better read up on it before you try this out. If you do, and have an OK understanding of how OO works in PHP, then read on! If not, read the article http://www.php.net/oop Now, understand that DOM XML is very particular about the syntax and such in an XML file. The file MUST start with the XML declaration (without quotes) ?xml version=1.0 in order for DOM to try and use it. Use the functions to read right through it all. You'll find that this is probably exactly what you need! I'd use DOM XML personally. I included the other in case you didn't want to have to install everything.

[PHP] Newbie Question - an If in an Array?
I'm so confused. I have an array :
$display[] =
div class='job-date'{$cv['dates']}/div
div class='job-title'{$cv['job_title']}/div
div class='company'{$cv['company']}/div
div class='job'{$cv['job']}/div;

You can do something like this...
function subEndWord ( $string, $start, $max ) {
$string = substr ( $string, $start, $max );
$string = preg_replace ( /\s\w+$/, , $string );
return $string;
}
Untested, but should work. Tinker with the RegEx to perfect it.

Re: [PHP] Newbie Question: breaking a substr() string on a space SOLVED
Hi, everyone,
Thanks for the great suggestions! I've looked at all and found that the
one here:
http://www.php.net/explode
that Jay recommended was the easiest for me to wrap my brain around. I
wll tinker with the other ones as well - it's all really interesting.
The function was:
function wordlimit($string, $length = 50, $ellipsis = ...)
{
$paragraph = explode( , $string);
if($length count($paragraph))
{
for($i = 0; $i $length; $i++)
{
if($i $length - 1)
$output .= $paragraph[$i] . ;
else
$output .= $paragraph[$i] . $ellipsis;
}
return $output;
}
return $string;
}
And boy does it work easily!!!
Thanks again all who replied.
Jack

It's really sensible and logical what you did. I really appreciate it.
1. $content = substr($article['content'], 0 200); // get first 200
chars is choking, and I've looked in docs and can't understand why.

2. This correction:
I´ve put the in front of title since the link otherwise would be
a href=a=1234title=sometext, which is not what You want I guess.
Wow. Actually I wanted it to make a href='a=1234' title='sometext' -
does this:
print lia href='{ . $_SERVER['PHP_SELF'] . }?a={$article_id}'}'
title='{$title}'{$article['title']}/abr /\n$content/li;
do that? (I ask because I can;t make any of it work?!)
Thanks so much for your help.

In this line, PHP is somehow encountering a T_NUMBER (a number) where
it
*expects* to see something else.
Like a comma.
Look between your 0 and 200 very carefully.
Thanks for taking the time. I had suspected that earlier, but when I
put it in all sorts of OTHER stuff happened.
Then I saw your post and tried again. I saw that I had made another
mistake later on. So you've solved that part - thanks!.
ExceptExcept it doesn't pull the content from the db and substr it
to 200 characters. It pulls the id number and the title no problem, and
I am sure that $article['content'] points to the right place (or at
least it's named right) but it's just not getting the content:
if (!empty($where)) {
echo
ul;
$article = mysql_fetch_assoc($result);

$variable!); will print Here is a variable: The value of the variable!
Single quotes are not parsed by the php engine, so the same code with
single quotes (print('Here is a variable: $variable!'); will return
Here is a variable: $variable! I hope that answeres your question
This is not quite 100% correct.
PHP still parses single quotes, but only replaces two (2) special
character combinations:
\' turns into '
\\ turns into \
The point is that you still might want to embed an apostrophe in single
quotes, and so you use \ for that, and you might want to embed \ so you
use \ for that as well.

[PHP] Re [PHP] Newbie Question re substr: Solved
Sorry if this posts twice. Thanks everyone for the help.
The missing comma was the problem with the display; the missing
specification of the column at the start of the sql query was the
problem with getting the data from the column.
Again, thanks all who replied for the fast and excellent help.

[PHP] Newbie Question re substr
Hi,
I'm really new and getting lots of help but need some assistance.
I'm running a script which gets specific articles from a database if
they're entered in the URL after the ? . For instance if someone asks
for
www.foo.com/index.htm?a=1234
then the script would look for an database entry with the id of 1234
and display it in the page.
If there's no number specified (www.foo.com/index.htm) or if the number
given is to an article which doesn't exist, it gets the titles of all
the articles available and prints them as links to the proper article
number.
I'd also like it to grab the first 200 characters of text from the
$content field of the entry.
With help I have the title link part and I suspect I'm close but I keep
messing up the syntax
The code is:
snip
if (!empty($where)) {
echo
ul;
$article = mysql_fetch_assoc($result);
} else {
while ($article = mysql_fetch_assoc($result)) {
$table_of_contents[] =
lia href='{$_SERVER['PHP_SELF']}?a={$article['article_id']}'
title='{$article['title']}'{$article['title']}/abr /
$article['content'] = substr($article['content'], 0 200);/li;
}
}
echo
/ul;
/snip
Can anyone help ?
Thanks in advance!

substr($article['content'], 0, 200)./li;

\
Which doesn't kick back errors but also does not pull any
$article['content'] - it leaves a line break but no text is being
inserted from the content row.

Single quotes are not parsed by the php engine, so the same code with

Double quotes expand variables, that is, if $a = 2, then echo The value is $a2; will print The value is 2. Single quotes return strings literally.

All of the information for the form is put in between a form method element. When I try to add code for a drop donw inside the form method element, the code doesn't work, and I get a parse error. The code will work outside the element. I assume I am just missing something dumb. Could someone please enlighten me. I can post my code if it will help.

[PHP] newbie question ; calling php script with parrameters from html
can i use this kind of construction in my html code ? a href=test.php?selection=highSelect high/a if yes , how do i retrieve the passed string in the php code Johan -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
AW: [PHP] newbie question ; calling php script with parrameters from html
Hi,
There are multiple Ways of getting that string.
If your PHP-Server has globals=on in php ini you will recive that string in
$selection variable.
If not you recive it in $_GET[selection]
So I use a function to handle POST and GET Variabels.
function getpost_ifset($test_vars)
{
$return = FALSE;
if (!is_array($test_vars))
{$test_vars = array($test_vars);}
foreach($test_vars as $test_var) {
if (isset($_POST[$test_var])) {
global $$test_var;
$$test_var = $_POST[$test_var];
$return =
TRUE;
} elseif (isset($_GET[$test_var])) {
global $$test_var;
$$test_var = $_GET[$test_var];
$return =
TRUE;
}
}
return $return;
}
If i now want to get a ariable i either POST or GET from an URL i don't care
if POST or GET.
I just do
getpost_ifset(selection);
and then I have a variable called $selection in my code with the given
value.
You could also do something like this.
if(getpos_ifset(selection))
{
echo Selection variable is there with value: .$selection;
}
else
{
echo No Selection Variable givin in Link;
}
Hope that helps.

Re: [PHP] newbie question
Hello Max,
Monday, November 15, 2004, 6:26:43 PM, you wrote:
MK } else if ($_POST[FirstName] != ) {
Where you use $_POST you should have the syntax as follows:
$_POST['var']
(note the quote marks)
Without them, PHP is going to think you're passing in a constant
called FirstName (etc) which of course you're not.
MK $add_table = INSERT into table values (NULL, '$_POST[FirstName]',
MK '$_POST[LastName], '$_POST[Address], '$_POST[City],
'$_POST[State],
MK '$_POST[Zip], '$_POST[phone],'$_POST[email]);
MK mysql_query($add_table) or die(mysql_error());
You really *really* shouldn't insert POST data directly into a table,
for reasons please see Chris's very good read on PHP Security here:
http://shiflett.org/php-security.pdf
But back to the question in hand - try and see what has happened,
extend your code a bit at the end:
mysql_query($add_table);
if (mysql_error($conn))
{
echo Something bad happened with MySQL: . mysql_error($conn);
}
else
{
echo There was no SQL error;
}
Try outputting the SQL (echo $add_table) and then pasting it into
PHPMyAdmin or a MySQL command session and see what it gives you. If
that works fine, the error is in the communication with the MySQL
server (authentication perhaps) and not the SQL itself.
Best regards,
Richard Davey

[PHP] newbie question
Hello all,
I am new to php programming and web programming in general. I have
created a php file that if it works will create a simple form for
inputing contact information and then once the submit button is
pressed, the information is saved into a MySQL database.
When I try to submit, I get no error messages, but no data goes into
the MySQL table. I have verified that my MySQL User and Password are
correct and I believe I am actually connecting to the database.
Please look at what I have created and tell me what I am doing wrong,
what I can do better, why I am an idiot, et .al.
Thanks,
Max

It's trivial for a malicious attacker to bypass your maxlength, just
an FYI. You should check with strlen() after the post, or possibly
look into javascript form validation.
Greg, I'm sure you already understand this but I just wanted to add to
your statement for those that may not.
Javascript should not be relied upon for data validation as a security
measure. It should merely be used as a convenience to the user (so they
don't have to wait for a page to reload just to see some error notices)
and to take load off the server (so the server does not have to process
a page 10 times while the customer refines their input to match your
criteria). Having said that, make sure to always have server side
validation in place even if you *do* in fact also use Javascript on the
client side.
Chris.

look into javascript form validation.

[PHP] Newbie Question: DHTML client Http Post to PHP running under Apache/Win XP
Does the PHP script have to be already running to communicate send a HTTP Post varibale to it (from a DHTML client browser)? Or can it initiate the HTTP Post fron the client that activates the PHP script? I know this must seems simple but I'm having troble receiving these varible from my client.

From: [EMAIL PROTECTED] Does the PHP script have to be already running to communicate send a HTTP Post varibale to it (from a DHTML client browser)? Or can it initiate the HTTP Post fron the client that activates the PHP script? Just like any other web page, the POST request causes the web server to start the PHP script which receives the posted values. They are then available in the $_POST array. print_r($_POST) is your friend here (and mine!!).

[PHP] (Newbie question) Advice on comment system (no db!) design issues
Hi! I am about to write a comment system in PHP, but as i am not any good at PHP i am seeking some advice. This is what i want from the system: * Flexibility! I want to be able to attach it where i want let the user give comments easily. For example comments could be on a blog entry or on a downloadable file, whatever i like it to be. * I will moderate all comments from all commentpoints before they are published. * Not use a database. I am wondering what the best approach is? I thought of this: Use an object oriented approach, and have a class called CommentSystem. When i create an instance of the class the commentpoint id (some integer/string) is passed and the comments are read into the object. After the object creation i can display all comments using something similar to: aCommantSystem-outputHTML() in my code. The inner datastructure holding the comments should be an array, perhaps multidimensional with different data in each column? When a comment is added using something similar to aCommantSystem-addComment($username,$comment,$date) the array has one element appended to it. Persistent storage of the commentsystem is done through serialize and unserialize and saved to a file with equal name to the specific commentpoint id. I will have some way to list all new comments from all commentpoints so that i can moderate them (accept/refuse) before they are to be viewed in public. I haven´t thought of some good way to do this though. Does the above sound like a good solution? Or should i do it in some other way? All feedback would be appreciated! -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
Re: [PHP] Newbie Question: Variables on the fly
ok let say that you have 2 or more variables with same name but there are
difference in numbering And Values like this :
$var1 = 1 ;
$var2 = 12 ;
// etc ..
now you must now how much of number of this varibles before you deal with it
or you must store it on array to know how to count it in the fly like this :
$var[var1] = 1;
$var[var2] = 12;
// etc ..
$var_count = count($var); // give you the count
now you can deal with vars like this :
$i = 1;
do {
$NewVar[NewVar.$i] = $var[var.$i] * $WhatEver ;
$i++;
}
while ($i = $var_count );
And finally you can extract vars by extract() to make them in normal shape
if you get my point

Subject: RE: [PHP] Newbie Question: Variables on the fly
Thanks for the reply Denis,
Let me elaborate a bit.
I have a php page which I want to pass a series of variables via a url
string.
eg
myPage.php?dataPoint1=10dataPoint2=20dataPoint3=30
The thing is I won;t know until runtime how many dataPoints there will be
so I have also included 1 additional url variable
eg
myPage.php?totalDataPoints=3dataPoint1=10dataPoint2=20dataPoint3=30
From there I want to take those data points and do several things with
each of them. The keep things simple lets say I want to multiply each by
3
and then divide it by 2 and put it into a new variable (under the same
naming system).
eg
$xtemp=$HTTP_GET_VARS[totalDataPoints];
do {
A line here which will take each dataPoint and multiply by 3 and
divide by 2 and assign it to a new variable with the same numbering system
(eg $myNewVar1=$HTTP_GET_VARS[dataPoint1]*3/2;
$xtemp--;
} while ($xtemp0);
Make any more sense?
Thanks.

Strictly speaking, your original question referred to what PHP calls
'variable variables':
http://us3.php.net/manual/en/language.variables.variable.php
However, most of what you can do with them can be done more simply
with arrays. In your example above, use
myPage.php?dataPoint[]=10dataPoint[]=20dataPoint[]=30
and you get an array
$dataPoint[0]=10
$dataPoint[1]=20
$dataPoint[2]=30
The number of data points is count($dataPoint). See
http://us3.php.net/manual/en/language.variables.external.php
for more info on this technique.

RE: [PHP] Newbie Question: Variables on the fly
Thanks for the reply Denis,
Let me elaborate a bit.
I have a php page which I want to pass a series of variables via a url string.
eg
myPage.php?dataPoint1=10dataPoint2=20dataPoint3=30
The thing is I won;t know until runtime how many dataPoints there will be
so I have also included 1 additional url variable
eg
myPage.php?totalDataPoints=3dataPoint1=10dataPoint2=20dataPoint3=30
From there I want to take those data points and do several things with
each of them. The keep things simple lets say I want to multiply each by 3
and then divide it by 2 and put it into a new variable (under the same
naming system).
eg
$xtemp=$HTTP_GET_VARS[totalDataPoints];
do {
A line here which will take each dataPoint and multiply by 3 and
divide by 2 and assign it to a new variable with the same numbering system
(eg $myNewVar1=$HTTP_GET_VARS[dataPoint1]*3/2;
$xtemp--;
} while ($xtemp0);
Make any more sense?
Thanks.

[PHP] Newbie question on arrays
Hi,
I've written the piece of code below and I do not get any output out of the 2
dimensional array. I do not see what's wrong. Must be something obvious I guess.
?php
$monthname[NL][1] = Januari;
$monthname[NL][2] = Februari;
$monthname[NL][3] = Maart;
$monthname[NL][4] = April;
$monthname[NL][5] = Mei;
$monthname[NL][6] = Juni;
$monthname[NL][7] = Juli;
$monthname[NL][8] = Augustus;
$monthname[NL][9] = September;
$monthname[NL][10] = Oktober;
$monthname[NL][11] = November;
$monthname[NL][12] = December;
$monthname[BR][1] = Janeiro;
$monthname[BR][2] = Fevreiro;
$monthname[BR][3] = Março;
$monthname[BR][4] = Abril;
$monthname[BR][5] = Maio;
$monthname[BR][6] = Junho;
$monthname[BR][7] = Julho;
$monthname[BR][8] = Augosto;
$monthname[BR][9] = Setembro;
$monthname[BR][10] = Outobro;

{
$date = getdate($timestamp);
echo mday = . $date['mday'] . ;

so no monthname!
[PHP] Newbie question on Array
Sorry, I am new and could not supply the correct search strings on search
sites to answer by question.
I am trying to construct an array with key-value from a resultSet which will
be used often within the page or between pages.
Which looks like this:
$optionBox=select used_1, rub from rub_table order by rub asc;
$rs_box=mysql_query($optionBox,$con);
$arr=Array(
while($row=mysql_fetch_array($rs_box))
{
'$row[used_1]' = '$row[rub]' ,
});
,--- This does not need to appear in the last loop.
Is this possible?, if yes what is wrong with my code?.
many thanks for your help..

It appears as if you don't have MySQL support compiled in with your PHP build. If you installed it from source you will want to recompile PHP with the --with-mysql option.

Unfortunately, strtotime() can't convert mysql timestamps of the form
MMDDhhmmss (the default 14 character timestamp). Here's a
function to do it for you:
function convert_timestamp ($timestamp, $adjust=) {
$timestring = substr($timestamp,0,8). .
substr($timestamp,8,2).:.
substr($timestamp,10,2).:.
substr($timestamp,12,2);
return strtotime($timestring. $adjust);
}
Remember that the $adjust string needs to be properly spaced- + 30
days, not +30days!

You can't have any output before trying to use header(). html, etc,
are considered output. So, the very first line in your file must be
?php and you can use header() before you echo anything within that PHP
block.

That's not entirely accurate.
---Quoted from http://php.net/header ---
Remember that header() must be called before any actual output is sent,
either by normal HTML tags, blank lines in a file, or from PHP. It is a
very common error to read code with include(), or require(), functions,
or another file access function, and have spaces or empty lines that
are output before header() is called. The same problem exists when
using a single PHP/HTML file.
header() doesn't need to be 'the first line of the page', but it does
need to be placed above/before any output gets sent to the browser.
bad:
html
? header(...); ?
bad:
?
echo foo;
header(...);
?
good:
?
include('something.inc');
session_start();
$foo = 'bah';
header(...);
?
if there's any code following the redirect (which you don't want to
execute), I'd also strongly recommend having an exit; after the
header():
?
include('something.inc');
if($foo)
{
header(...);
exit;
}
// some other stuff that shouldn't get executed after redirect
?

[PHP] newbie question about scope
I am an experienced web developer who is just getting into php. I have had a php project fall into my lap and wanted a little advice. Here is the scoop: A client moved their site from a server (unknown details) to a hosting facility (php 4.3.2). Now none of the scripts work. I have guessed that they are coming from an earlier version of apache/php. Anyway it appears that whoever created the site in the first place did not believe in scoping variables. Now any variable that is not properly scoped will not be read by the server. I know I can simply scope all of the variables, but I was hoping there may be an easier way. Also, how bad is the _REQUEST scope I read that it could not be trusted, however the previous developer created the app in such a way that several places a variable could be _GET or _POST. I apologize for the rambling and possible incoherency of this message, I am a bit tired. Matthew PS.

The server probably has register_globals Off, where previously he was programming with it being On. or vise-versa. They should be Off, and should be left off, but programming with them off needs some adjusting. Variables such as post and get data are now 'superglobals', and must use the appropriate arrays; $_GET[], and $_POST[].

[snip] A client moved their site from a server (unknown details) to a hosting facility (php 4.3.2). Now none of the scripts work. I have guessed that they are coming from an earlier version of apache/php. [/snip] It is likely then that register_globals is set to OFF in the php.ini. In earlier versions this directive was set to ON. It was a security issue that was more about bad coding than a PHP vulnerability. If you passed a form field with the name of userName it could be accessed by PHP in the $userName variable, with RG off you would have to access it via $_GET['userName'] or $_POST['userName'] dependent upon the processing method of the form. [snip] Also, how bad is the _REQUEST scope I read that it could not be trusted [/snip] Again, bad coding would present a danger here. [snip] PS. How do you scope queries?

Now none of the scripts work. I have guessed that they are coming from an earlier version of apache/php. Anyway it appears that whoever created the site in the first place did not believe in scoping variables. Now any variable that is not properly scoped will not be read by the server. I know I can simply scope all of the variables, but I was hoping there may be an easier way. Also, how bad is the _REQUEST scope I read that it could not be trusted, however the previous developer created the app in such a way that several places a variable could be _GET or _POST. I apologize for the rambling and possible incoherency of this message, I am a bit tired. Matthew PS. How do you scope queries? You're thinking about this in the wrong way, it seems. The server probably has register_globals Off, where previously he was programming with it being On. or vise-versa. They should be Off, and should be left off, but programming with them off needs some adjusting. Variables such as post and get data are now 'superglobals', and must use the appropriate arrays; $_GET[], and $_POST[]. There are things like extract(), but using them is not advised. as per your question about scope queries, be more concrete :) I agree that is the way it should be, but my client is looking for a quick fix, not a good one. In the end it is fortunate for my client that the quick fix is not a viable one. I agree that all variables should be scoped, it is the right way to do things. I think I have my query question figured out. Thanks -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] newbie question about scope
[snip] Unless I'm misunderstanding something, PHP does not implement scoping (at least in the sense that many other programming languages do) prior to PHP5.

Re: [PHP] Newbie question about Class
Hi Al Sessions and objects are quite easy to use in the latest version of PHP, and would be my personal recommendation. I have a coupleof test scripts that I regularly mangle when trying to see if something is doable...if you like, you can contact me offlist and I will mail these to you and you can try it out for yourself.
