I think someone else already mentioned this, but let me emphasize
that this is a terrible idea and definitely does not make things a
little more secure.
The best analogy I can think of for a cookie would be handing out
name tags to people who visit your site. Imagine that you write the
following SQL on someone's name tag:
select * from foo where unique_id='12345'
This helps you distinguish them from the next person who may have a
unique identifier of 23456. While this might work for those who play
by the rules, you are placing a tremendous amount of trust in these
people. What if someone erased what you wrote on their name tag,
replacing it with this:
delete from foo
If you were to trust this person's name tag the next time you saw
them, you would delete all of the data from that table.
In addition to this, hidden form variables are just as bad. It is a
different method, but you are still basically sending something to
the client and just trusting the client to return exactly what you
sent. Placing so much trust in the client is never a good idea.
I would recommend abandoning these methods for anything that you, as
you say, are wanting to make more secure. Look into using sessions
instead. When you use sessions, the only sensitive data you trust the
client to return to you is PHPSESSID. While there are some dangers
associated with this trust, it is a more tolerable risk. When you set
a session variable, it is kept safely on the server, so it is at
least much less convenient for an attacker to alter this data,
because only you can do that.
I hope this helps you get started down the right path. There are
methods you can use to further mitigate the risk of trusting the
client's PHPSESSID, but that can be discussed later.

I took the liberty of changing the subject of your e-mail because this
way everyone can follow it better.
Well, you can execute the ping command directly from within PHP and then
parse its input. For example:
<?php
preg_match ("/([0-1]) received/", shell_exec ("ping -c 1 -w 2
www.phparch.com 2>/dev/null"), $a);
if (count ($a) && $a[1])
echo "success";
else
echo "failure";
?>
This will work only under Unix, but you can very easily adapt it to
whatever os you need, as long as it supports pinging from the command
line.

I am sure this question has been answered, but there is a ton of data to
sift through on this. I am running Apache 1.3 and the latest PHP 4.2.3. .
I am just working with variables and I cannot seem to get them to pass from
my html file to the php call. I will get the html portion fine, but not the
variable. I have checked my language and have compared my files with
supposed good code from a reliable source with the same results. Any idea on
this. It happens on multiple systems.

Is your register_globals setting set to Off? This is the default setting in
v4.2.x upwards.

I wrote this function to fetch a news item off another web page but with
a little modification it should work for you. To use it you needed to
identify a set of of strings in the source to use as anchors ($start,
$end) and then it pulls that section and crops off the anchor text so
you are left with just what you wanted.
<?
function get_item($url, $start, $end) {
global $item;
if(!($fp=fopen($url,"r"))) {
echo $url." is not accessable";
exit;
}
while(!feof($fp)) {
$item.=fgets($fp,255);
}
fclose($fp);
$start_position=strpos($item, $start)+strlen($start);
$end_position=strpos($item, $end);
$length=$end_position-$start_position;
$item=substr($item, $start_position, $length);
}
echo $item;
?>
Soemthing like this might work for you:
<?
$results=search results;
$keyword=search string;
$startposition=strpos($results, $keyword)-200;
$endposition=strpos($results, $keyword)+200;
$length=$endposition-$startposition;
$item=substr($item, $startposition, $length;
echo $item
?>

Try this function, Ijust wrote it for the same purpose. You just need a
unique string in front of the stuff you want, and one after it. You
can usually get a string of code on either end that will do this. The
function will open the URL, find the anchor strings you told it, then
strip them away leaving only the text/code that was in between them
<?
function get_item($url, $start, $end) {
global $item;
if(!($fp=fopen($url,"r"))) {
echo $url." is not accessable";
exit;
}
while(!feof($fp)) {
$item.=fgets($fp,255);
}
fclose($fp);
$start_position=strpos($item, $start)+strlen($start);
$end_position=strpos($item, $end);
$length=$end_position-$start_position;
$item=substr($item, $start_position, $length);
}
echo $item;
?>

If the target is in well-formed XML (XHTML is an example), you could use
XSLT
to say 'i want the third column of a particular row - in this instance,
Melbourne'. However, since few people actually adhere to standards, you're
probably going to need a regex... if you're not comfortable with them,
explode() could be useful (although it is slower)
Somebody posted an extremely helpfull little quick reference at

Try using fopen() to open the file and then fread() to read it into the

No John. I'm ok with simply inputting a value and otherwise using
arrays that are hard coded and previously named but my problem is in
creating different arrays on the fly to represent each column that
there is a name for. I want to end up with something like $meat[] and
$potatoes[] and whatever else is needed from a list... The list of
meat, potatoes, etc determines how many arrays and their names.
I'm not to swift when it comes to arrays and think I'm probably stuck
on some simple misconception. I'm trying to convert $meat to $meat[],
on the fly, to have something to input to... I read today maybe I
don't need the brackets?

Floyd,
if you are using mysql then you can use the mysql_list_fields to get the
names of the mysql table's column (field) names, then do mysql_num_fields to
get the number of columns (fields), then fill the columns with whatever
using a while loop.
I've attached a php page that fetches this info from any size table then
displays the table. You can extract the info you need and extend it with
check boxes etc.
Hope this helps.

I have a html form that has just 3 fields and each are defined as

$subject = "Form Submission";
$contents = "$firstname, $lastname, $email";
mail ($to, $subject, $contents);

When submitting the form, mail gets sent to [EMAIL PROTECTED] with the

I suppose you are trying to do the following:
$variable = "some value";
So if you wish to assign "string" as $string, simply do the following:
$string = "string";

I have a simple post script and I want to make it so if a user
types in a URL of some sort, to change it to make it clickable. How could I do
that?

not entirely sure what is going on there, but if the user is entering
the url in a html form. Then just grab the variable on the next page
and run this
$url=user $HTTP_GET_VARS["url"]; (or $HTTP_POST_VARS depending on your
form method)
$url="<a href=".$url.">".$url."</a>";
echo $url;
the only way to change it dynamically on the same page would be javascript.

They are entering in a whole paragraph or two of text and I want to search
the paragraph for URLs then make it a clickable URL and then store it in a
MySQL database.

hi,
can anyone tell me how to make auto backups of mysql databases?
i have a particular database that i want to backup everyday. what i can
think of now is to use crontab to execute a .php that will do the work, then
send the db schema (dump) via email every midnight.
however, i do not know the code to GET THE DUMP of the mysql db.
i know that i can be done because phpAdmin from sourceforge.net has the
export feature, which does what i want, except that i cannot execute the
hyperlink there using crontab.
can someone tell me:
1. what is the php code for getting the schema?
2. what is an alternatively BETTER way to backup?
thanks in advance
Yours sincerely,
See Kok Boon

Answer is No. 2)
Use cron to run the mysqldump utility instead of a php script.
Let me know if you need more info.
Cheers

I use this one with crontab, it works pretty well, if your email program
can handle uuencode:
#!/bin/sh
# File : db_backup.sh
# Descript: Runs a ful mysqldump of one or more MySQL databases, uuencodes
# and compresses them, and mails them to a specified address.
# Requires mysqldump, gzip, uuencode, mail or mailx, and crontab.
#
# Normally this run from crontab, with an entry like:
# 0 3 * * * sh ~/db_backup
#
# Version : 1.00
# Author : Morgan Hughes ([EMAIL PROTECTED])
# License : Copyright (C) 2002, Morgan Hughes. Use freely.
# Account/password/email info
db_list="your_database"
db_user="your_username"
db_pass="your_password"
email="your_email_addy"
# program locations
mysqldump="mysqldump"
dump_opts=""
uuencode="uuencode"
gzip="gzip"
mail="mail"
# Actual code
for db_name in $db_list ; do
date=`date '+%Y%m%d-%H%M%S'`
$mysqldump $dump_opts -u $db_user "--password=$db_pass" $db_name | \
$gzip -c9 | $uuencode "$db_name-$date.sql.gz" | \
$mail -s "DB backup, $db_name, $date" $email
done
# Ends : db_backup.sh
At home I have a script plugged into .procmailrc with an entry like:
# First off, catch inbound automated backups.
:0
* ^Subject: DB backup, kyhm
| ~/bin/catch_backup ~/kyhm.com/backups/db
The ~/bin/catch_backup script is as follows:
#!/bin/sh
if [ "$1" != "" -a -d "$1" ] ; then
cd "$1"
else
cd ~
fi
cat | uudecode
Hope this is useful...

Hi,
I am looking to secure my php install, like the settings in php.ini etc.
I am using apache 1.3.27 and running latest php.
Is there like a tut or something that can take u thought the php.ini and
explain ina little more detail?
safe_mode = Off
is that a bad idea or should i leave it on..

hi,
you should try to take the php.ini-recommended and edit it a little bit so that it
fits your needs.
the settings there are very secure but also increase php's performance and coding
standard.
if some settings won't fit to a single script, you can use ini_set(..., ...).
so you'll have to disable the output_buffer if you need implicit_flush.
and you safe_mode question.. sorry i never played around with it ;)
bye

Ok, please forgive my ignorance, but in PHP isn't $_COOKIES the same as
$_SESSION?. I thought it was if the user had cookies turned off (and
even if the user had cookies turned on come to think of it) ... If not
I'm in trouble.
I was always under the impression that $_SESSION vars were passed as
cookies ...

I 'm not where I can test this right now, but if a session is older
than session.gc_maxlifetime, isn't it invalid anyway? I.E. if I
bookmark a page on your site and then come back 3 hours later passing
an old SID, shouldn't that session have expired on the server by that
time, in which case the session vars would be empty and you could kick
me back to your login page?
If my understanding of sessions is correct, no.
session.gc_maxlifetime does set the lifetime of a session, but a session
will not be cleaned by PHP until session.gc_probability has been hit.
Again, if my understanding is correct, PHP doesn't automatically check
to see if a session has expired before accessing it. It pre-supposes
that any session file lying around is till active. And those session
file will stay there until session.gc_probability has been hit.
I might be wrong though ...

Then I suppose it's just an added feature of the session handler I am
using. Maybe the OP should give it a shot, as I use it and I
definitely don't have a problem with expired sessions
I'll think about writing my own session handler as it can be quite
useful. However I need to evaluate the amount of extra disk read/writes
it would add. Using a DB vs the file system does add some overhead ...

I have always had the opinion that the more comments you put into php
scripts, the slower they will run because there is more data to be read...
Can someone tell me if there is any truth in this or whether commenting has
absolutely 'no' impact on the performance of a script?
Thanks,
Adam.

If I declared an element indexed array and put some values into it:
$a['element1'] = array('btime' => '19D', 'etime' => '22D', 'dayname' => 4);
$a['element2'] = array('btime' => '12D', 'etime' => '20D', 'dayname' => 2);
$a['element3'] = array('btime' => '15D', 'etime' => '17D', 'dayname' => 3);
I would like to ask that how can I completely delete the $a['element2'] in
the array? That's mean I will get 'false' in 'isset($a['element2']) after
the delete process is taken place.
Thanks for your help.
Regards,
Michael Wai
