[snip]
Before the if statement in your loop place this line:
echo "\$i is now: $i";
You'll notice that most probably your $i variable will miss $target by some
hunderths or thousandths, since you're working with it as a float. This is
due to the way fp numbers are stored and calculated (using exponents and
mantissa).
Workaround: don't use floats if you want to hit a certain value at the spot:
$i - $target, By God, the are equal in value.");
} else {
echo ("$i - $target, Eternal Damnation, they aren't
equal!");
}
}
?>

Re: [PHP] OT Inactivity Timeout

[snip]
That's an interesting question - something that might be handled
server-side (which is usually a lot safer than on the client side),
supporting (javascript-based) client requests if it is still logged-in.
I have tried a quick sample and believe a scenario like this could work
quite well in a production environment:
(1) handle login status server-side:
After authenticating the user, establish a timeout until that the login
will be valid WITHOUT user interaction (you may e.g. choose 5 minutes, i.e.
time() + (5*60)). Store this timeout value in session data
($_SESSION['login_valid_until']);
(2) update the timeout on every user interaction
Simply refresh the session based timeout value using the same formula.
(3) Have a special entry (either a special script, or a certain parameter)
where the client may ask if the login is still valid. Make sure this script
(and only this!) DOES NOT increment the timeout value since it will be
called by client javascript, not by user interaction.
(A) Header pseudocode for "interactive" pages (normal application scripts):
login valid and validates against timeout?
NO: transfer to "you have been logged out" page
YES: increase timeout; continue processing;
(B) Pseudocode for timeout-checking script:
login valid and validates against timeout?
NO: transfer to "you have been logged out" page
YES: return "204 no response" status code
(C) Javascript to be used on any page:
function checkHandler() {
window.location.href="yourcheckscripthere.php?<?php echo SID; ?>";
onloadHandler();
}
function onloadHandler() {
setTimeout('checkHandler();', 6);
}
The main feature here is the use of the server status code 204 which means
"No Response". Cited from RFC2616 (HTTP 1.1 draft standard):
10.2.5 204 No Content
The server has fulfilled the request but does not need to return an
entity-body,
[...]
If the client is a user agent, it SHOULD NOT change its document view from
that which caused the request to be sent. This response is primarily
intended to allow input for actions to take place without causing a change
to the user agent's active document view, [...]
The 204 response MUST NOT include a message-body, and thus is always
terminated by the first empty line after the header fields.
So: if the server sees the login status (in session data) is still valid,
the reload request issued by JavaScript doesn't lead to a new page but lets
the browser remain in "idle" mode. However the timeout needs to be set
again; it seems that the JS engine clears all timers _before_ the reload
request (which would make sense; it can't clean them up on another page).
However if the server sees the user has exceeded its timeout (by not
activating some "interactive" action that would cause the timeout to be
extended), the javascript reload will immediately transfer the user agent
to the "you're outta here" page.

I just found this thread, pardon me if I'm off topic, but something like
this should work for you. It makes use of the fact that all of the replace
functions can take arrays as input parameters.
$from = array("/(\r\n)+/", "/(\n\r)+/", "/(\r)+/", "/[\x0..\x19]/");
$repl = array("\n", "\n", "\n", null);
$str_cleaned = preg_replace($from, $to, $str_uncleaned);
This construction should convert the occurrence of one or more successive
newline combinations with a single newline character, and remove control
characters at large (untested).

[snip]
Please don't take this personally but I dislike this approach to allow a
user to access some information he has to validate for. As soon as a user
gets to know that he can access the info page just by entering the
"info.php" URL, maybe together with a user ID as parameter, he will do that
(at least he can bookmark the location he should login to). This is
completely against the general idea of authentication...
What I'd do is to validate the user, setup a session where the user id is
stored (which is server side anyway), then branch to different sections of
my app, not by means of redirect but by including() the necessary code.
You may pass the user token to the next page in two different ways:
(a) pass them as query parameter (see rant above):
header ("Location: $FF_redirectLoginSuccess?" .
"mmu=" . urlencode($MM_UserName) . "&" .
"mma=" . urlencode($MM_UserAuthorization));
(b) just more secure and elegant is simply handing over the session:
header ("Location: $FF_redirectLoginSuccess?" .
session_name() . '=' . session_id());
The latter of course will only work if it's the same host, and the same
machine so PHP will have access to the session data in question.

[snip] At the first glance I see 3 items where the first one might be the culprit: - if your query is exactly as you sent it here you're missing a comma after the closing bracket of "concat()", just before "name" - before constructing the query make sure $attributes['nametofind'] is formatted correctly, esp. correctly escaping single quotes - when using double quotes to construct a string you don't need to escape single quotes. -- >O Ernest E.

The rule for AND chains is:
- evaluate the expressions from left to right
- stop AND DON'T RUN THE IF-BLOCK at the first expression evaluating to false
The rule for OR chains is:
- evaluate the expressions from left to right
- stop AND RUN THE IF-BLOCK at the first expression evaluating to true
This feature is inherent to all (well, most at least) languages - so be
aware of side effects (or no side effects occurring) with such constructs.
To allow _all_ expressions to be evaluated you need to run all 3 by
themselves, later comparing the results:
$x1 = test1();
$x2 = test2();
$x3 = test3();

[snip]
If you perform an HTTP request indicating a version of 1.0 or higher, a bit
more info is required for the server to process the request. Your simple
GET statement would probably work if you indicate HTTP/0.9, but it is
questionable if the receiving server would direct the request to the
correct domain (would only be if this was the "default domain" for the IP
address).
For a complete reference on the HTTP protocol look at RFC2616
ftp://ftp.rfc-editor.org/in-notes/rfc2616.txt
In short for your request to work you should at least transmit these lines:
GET /lang_fr/ index.php HTTP/1.1 [CRLF]
Host: www.myhost.com [CRLF]
Accept: */* [CRLF][CRLF]
where [CR] is a _complete_ CarriageReturn/LineFeed sequence "\r\n". Of
course you may add more headers to it.
You might also want to check out cURL for threaded requests.

May I?
It's usually not a good idea to re-seed the randum number generator during
a single script instance, as this might use the same seed more than once,
resulting in the identical random sequence...
To avoid reseeding, you could e.g. use a static variable in your
randNumber() function:
function randNumber($min=1000,$max=9)
{
static $is_seeded = false;
if (!$is_seeded) {
$is_seeded = true;
// build a seed
list($usec, $sec) = explode(' ', microtime());
$seed = (float) $sec + ((float) $usec * 10);
// seed random generator
srand($seed);
}
...
I prefer to add a string generated by uniqid(), such as
uniqid() uses the entropy generated by the opsys random device (if
available) in an attempt to make this truly random.

These are notices only, not errors (notices being the least severe level of
issues PHP may warn you about). You may adjust the error reporting level
with the error_reporting() function, or the corresponding setting in the
php.ini file.
"Undefined index": this means that the associative array doesn't have an
index field with a particular name defined. PHP will return null in this case.
Workaround: if (array_key_exists('REMOTE_ADDR'))...
"Undefined variable": the variable you're using has not been defined and
never been assigned to. PHP will return null in this case.
Workaround: if (isset($page))...

What I'd try (and I already did such stuff with success) is to just create some DB entries, in your case this would mean to add a "validation request" entry to a database, or even simply a "todo" file. Another process, most certainly run by a cron job, would then read the DB (or the toto file) and perform actions necessary. When done it would update some kind of status flag. On your website yo could display something like "187322 addresses scheduled for validation - 123499 to go", or something like that, just by reading the status data updated by the cron job. -- >O Ernest E.

{php_source_directory}/ext/session/session.c
this has it all - look for _php_create_id().
Basically it generates an MD5 digest from the current secs and usecs
(system time) and a pseudo-random number (see php_combined_lcg() in
standard/lcg.c). If an entropy file is available (usually on unix systems)
it uses the entropy to further randomize the digest. In a final step the
digest is converted to a hex string.

You can use a regular expression for this task. This is what I use for my

$out = null;

'abc defghijklmno pqrstuvwxyz' .

echo $test, '', nl2br(make_maxlen($test, 25));
Note that the make_maxlen function returns strings split up merely with a
newline character, so use nl2br to create a forced newline. There's no
drawback in not using nl2br (not adding ''s) since the inserted
newline character will be visible as whitespace and allow the user agent to
properly reformat the text within the area.

No - if the onClick handler returns false, nothing will happen. That's the
original reason for the onClick handler to be there - it can take control
if a link is actually performed or not.

[snip]
To have a browser handling data it receives as downloadable file you must
set a Content-Type it cannot handle inline, and specify a disposition and
filename, such as:
Content-Type: application/octet-stream
Content-Disposition: attachment;filename="myfile.jpg"
Content-Length: 1234
Note that it is always a good idea to tell the browser the size of a file
it is about to receive. Since imagejpeg() outputs the stream directly and
doesn't giv you any size information, you may use output buffering to
obtain the stream, like:
ob_start();
imagejpeg($im, '', 85);
$image_size = ob_get_length();
$imgstream = ob_get_contents();
ob_end_clean();
// continue as outlined above
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment;filename="myfile.jpg"');
header('Content-Length: ' . $image_size);
echo $imgstream;
exit;

try a preg_match like (untested):
if (preg_match('/^\s*([^0-9]*)\s*([0-9].*)\s*$/', $address, $aresult)) {
$address = $aresult[1];
$number = $aresult[2];
}
else {
$address = trim($address);
$number = null;
}
Note that preg_match will return false here if no number is available in
$address. Leading and trailing spaces are trimmed from $address and
$number, either by the regular expression, or by the trim() function in
case of a no-match.
Note also that this will fail for US-style addresses like "9th street",
moving everything in $number, leaving $address empty.

You cannot stat() (i.e. use filesize()) a remote file, filesize() will
return false making your script read 0 (zero) bytes.
When reading remote files you may consider chunking them:
$fh = fopen('http://www.weather.com', 'r');
if ($fh) {
while ($chunk = fread($fh, 4096))
echo $chunk;
fclose($fh);
}
This will work perfectly (if url-fopen-wrapper is enabled in your build
anyway).

This won't work anyway since your class test is declared after using it -

Possibly using array_keys()?
$keys = array_keys($doo);
echo "First key is \"{$keys[0]}\"";
array_keys() comes in handy if you want to have random access to an

This won't run I believe...
Code it like this:
$EricCodesArray = array (
"CO" => array("Description", "Input Name", "Select Name", "Option Name",
"Option Selected",),
"AN" => array("ERIC Number", "EricAN", "SelAN", "AN", "AN «Annotation»",),
"TI" => array("Title", "EricTI", "SelTI", "BT", "BT «Book Title»",),
);
Then you may reference an element within a subarray:
echo $EricCodesArray['TI'][2]; //should display "SelTi"
Note that non-numeric array indices (a.k.a. associative arrays)
a) should always be quoted, and
b) are case sensitive.

Yes it _is_ global, but within the function you need to declare if global
to have access to it, if you miss this you're referencing a local variable,
which is not defined...

The implode statement will indeed create a single line, that's what you
tell it to do... if you want a line per value, you need to specify the
newline separator, such as
implode("\n", $_POST);
Or am I off topic?

[snip]
Hmm - that's a bit different.
1) You can't use variables in singlequoted strings - these don't get parsed
by PHP.
2) You can absolutely use variables in doublequoted strings as these do get
parsed.
3) Array indices and object references must be enclosed in curly brackets
when used within double quotes to tell PHP what the variable and what the
string text is.
Example:
"cherpdocs/$annrow[id].doc" <== doesn't work correctly
"cherpdocs/{$annrow['id']}.doc" <== will work
"cherpdocs/$object->docname.doc" <== will not work
"cherpdocs/{$object->docname}.doc" <== will work
Note that you should quote non-numeric array indices to allow PHP to
recognize it's not a defined value. Omitting quotes for index data would
trigger a warning (something like 'using unknown identifier id, assuming
"id"').

You just cannot directly run any PHP script by URL if it's located outside the web root, but you could easily use stub files running that part of the application you wish to use. I assume you have some libraries that you'd like to include in your stub files: -- stub.php So there's no real need for an .htaccess-based blocker. However here's what you need in .htaccess )line numbers only for explanation below): 1 AuthName "The name of your realm" 2 AuthType Basic 3 AuthUserFile /etc/httpd/.htpasswd 4 AuthGroupFile /etc/httpd/.htgroup 5 Require group authorized_users 6 Order deny,allow 7 Deny from all 8 Allow from 10.10.10.0/24 9 Allow from ##.##.##.## 10 Satisfy any Explanation: 1 - This is the text that will appear on the authentication dialog at the clients side. 2 - There are others (like NTLM) but I don't have any experience using them. Take care that "Basic" doesn't provide any encryption of transmitted UserID/Passwords; it just Base64-encodes it. 3 - Where the password file is located. It may be anywhere, even outside the web root, as long as it is readable by Apache. You create and maintain the .htpasswd file using the htpasswd command line utility. 4 - Optional; contains user groups. Maintained by text editor. Format: group: user user user group: user user user 5 - Names of user groups that may access the ddirectory. You may as well use Require user user-id user-id if you don't support groups. 6 - Order of ACL check (http://httpd.apache.org/docs/mod/mod_access.html#order) 7 - Deny all hosts and users (checked first, see 6) 8 - Allow from the internal network (example, not required) 9 - Allow from any other IP or subnet (example, not required) 10 - http://httpd.apache.org/docs/mod/core.html#satisfy Allow access if _any_ of the above restrictions is met. If you specify Satisfy all the above example would never allow access since no host can be on different addresses... Note that "AllowOverride AuthConfig" must be set in the server or virtual host definition if authentication is to be used via .htaccess. The authentication directives can be used in the server config at the level, or in the .htaccess file. Formore info on Apache directives read http://httpd.apache.org/docs/mod/directives.html.

Try to add the Content-length header and see if this resolves your problem:
header("Content-type: application/text");
header('Content-Disposition: attachment; filename="variables.txt"');
header('Content-Length: ' . strlen($contents));
I made a habit to send the "filename" part in double quotes - some user
agents seem to require this although it's not required by RFC (RFC822,
RFC2183). Since doing this it always works for me :)

[snip] Bitwise comparison means just that, i.e. comparing two numbers bit by bit. Any number is represented by a bit combination (this has technical reasons - if a single "wire" has some electric potential set it's "1", if not it's "0" (or is it the other way round? Can't remember...). A single "Byte" is comprised of 8 such lines, each line representig a "Bit" with increasing value. To read this correctly you need to have a monospaced font: line number 7 6 5 4 3 2 1 0 | | | | | | | | | | | | | | | | line value 7 6 5 4 3 2 1 0 as power of 2: 2 2 2 2 2 2 2 2 dec. value: 128 64 32 16 8 4 2 1 Taking this, the decimal number "4" would look 0100 written in binary notation. Ok, now let's bitwise AND 4 and 4, walking bits left to right. If both bits are set the resulting bit is also set (for an AND operation), if one or both bits are not set this yields a zero bit: 0 & 0 => 0 0 & 0 => 0 0 & 0 => 0 0 & 0 => 0 0 & 0 => 0 1 & 1 => 1 0 & 0 => 0 0 & 0 => 0 I hope it seems logical that the result of bitwise ANDing a number to itself always will result in the same number... There are a couple of bitwise operators: & (AND): the result contains bits set in both operands | (OR): the result contains bits set in either operand ^ (XOR): the result contains bits set in either one or the other operand, but not in both (0 ^ 1 = 1, 1 ^ 0 = 1, 1 ^ 1 = 0, 0 ^ 0 = 0) Unary operands: ~ (NOT) reverses all bits of the single operand, e.g.; ~4 => 251 (~ 0100 => 1011) Bit-Shift operators move the bits of a number to the left or right: << left shift ($a << $b means shift bits of $a $b-times to the left) e.g. 4 << 1 = 8 (0000 0100 << 1 = 0000 1000) >> right shift ($a >> $b means shift bits of $a $b-times to the right) e.g. 4 >> 1 = 2 ( 0100 >> 1 = 0010) HTH, -- >O Ernest E.

[snip]
These are two totally different operators:
& - bitwise AND
&& - logical AND
So: 5 && 2 yields true
5 & 2 yields 0
In your example we would need to know the value of INPUT - it is most
certainly one of 1, 2, 4, 8, etc, denoting a single bit. So the expression
$search->level & INPUT
would yield nonzero (a.k.a. true) if the bit denoted by INPUT was set in
$search->level.

To execute any code contained within a string you need to eval() it.
Assuming you have this piece of code
$uname = 'Leo';
$text = "Hello there, ";
eval("?>$text2. If I instead include a file would it have access tio the local

Yes. See http://www.vogelsinger.at/test.php for an example (will be

[snip] You mean the SID constant I assume. This constant is only defined if the client didn't send the right cookie. There's no global variable holding the session identifier - you can use session_id() to retrieve (and set!) the current session identifier, and session_name() to retrieve (and set!) the name of the session (which usually is PHPSESSIONID).

Rewrite this to just

No need to echo here.
Using output buffering the 1 would still appear, some microseconds later...

This happens if the included file returns some value, in your case it seems

"return;" if necessary) and the 1 will be history.

[PHP] Login via PHP: Protecting files and directories
Hi all, since this has been asked a lot the last weeks I've published a nice little script for a generic login system using the HTTP authentication method via the "401 Unauthorized" header. It is available at http://www.vogelsinger.at/protected.html. Its main features are: - Protects directories - Protects single files in directories that are otherwise not protected, even in the server root folder - Supports multiple "realms" on a directory level - Supports multiple document types by matching a document extension to the correct MIME type - Supports inline display and downloadable files configurable by extension - Supports multiple users with different privileges, on a directory level - Privileges are inherited for subdirectories except when overridden - Standard HTTP Authentication Mechanism - It is not necessary to develop an integrated login system - Supports execution of PHP scripts under the "protected root"! The basic idea is to setup a "shadow tree", outside the web servers directory tree. For example: Web server Shadow tree / (root) / (root) /--public_files/--protected_files /--images /--images By placing a document in the root directory of the shadow tree it will be protected by a login, while still accessible via the standard url http://yourserver/thefile. The same is true for the /images folder; the /protected_folder directory would be protected as a whole. The script works as an error document for the "404 Not Found" error and has been tested with Apache 1.3.27/PHP 4.2.3. User authentication may be freely configured; the script must be modified here to meet the demands of each user. Yes, of course, if a document is effectively not found it serves a standard 404 error... Donated to the public domain :) For support just email me ... I'll try to answer questions whenever I have time. -- >O Ernest E.

[snip]
Try to see it this way: $manilist[$i][0] is a PHP expression, thus needs to
be put in curly braces _as_a_whole_ within a string.
It doesn't hurt to use curly quotes even if they're not necessary - it's
just the same as with using brackets in expression to clarify operator
precedence: with brackets, you don't have to fear any performance impact
and gain the clarity of the evaluation sequence; with curly quotes, you
gain the correct result :-)

in main.php, try to make $colour global:

This seems to me like an inconsistency within PHP as to when variables are
"automagically" available, and when you have to declare them global.
However you should avoid using globals anyway...

Note that you need to put curly braces around an array dereference if you

This doesn't work:
$s = "Some $array[sample]";

This would be my choice and is exactly what I'm doing, not only for database objects but for all other objects I'm using. This is my approach: I have a centralized object storage. No global variables, only a couple of public functions. For example, the function (note: not a method) "pos_getobject" returns a reference (!) to any object. If it doesn't exist it will be created. The syntax is: $hObj =& pos_getobject($id); where "$id" is the object ID. This ID could be either a constant (e.g. OBJID_DATABASE), or an ID referencing a database-persistent object. In my case, object ID's that are negative numbers are predefined objects (e.g. OBJID_DATABASE), positive numbers are DB persistent objects (simply the row-ID where the object header can be retrieved), and non-numeric IDs are temporary objects that may be created at runtime. If you don't need to take such a general approach I'd create a public function to retrieve the database object: $hDB =& pos_getDB($dbid); where $dbid is a database identifier in case you need it.

You might use output buffering:
ob_start;
write_string(5);
$my_string = ob_get_buffer();
ob_end_clean();
Output buffering is stackable, i.e. the above code will work even if you
have ob turned on already.

If you have the ability to use mod-rewrite, you can do

This can be done either in the general configuration, within ,

To understand the header lines you need to have some basic knowledge of the
HTTP protocol. Start eating tht HTTP RFC:
http://www.w3.org/Protocols/rfc2616/rfc2616
This will also enlighten yo about the fact that a header cannot be senz
after content has been pushed out.
This said you can use output buffering
(http://www.php.net/manual/en/function.ob-start.php) to avoid output being
sent before the headers:
Example:
ob_start();
echo "some stuff";
// we decide to redirect the client
ob_end_clean(); // clear the output buffer
header('Location: http://somewhere.com');

Using the layout you are showing:
1) Read the file
2) Split headers from body (delimited by an empty line)
3) make an array from the headers, splitting each line by ': '
// Disclaimer: untested
// step 1
$hf = fopen($file, 'r') or die("Can't read $file");
$buffer=fread($hf, filesize($hf));
fclose($hf);
// step 2 - now you have the chapter ready
list($headers, $chapter) = preg_split("/(\n|\r|\r\n|\n\r){2,2}/s", $buffer);
// step 3
$headers = preg_split("/(\n|\r|\r\n|\n\r)/s", $headers);
$arkeywords = array(); // for the "array" method, see below
foreach ($headers as $line) {
list($var, $value) = preg_split('/:\s*/', $line, 2);
// you may rather use an associative array instead of variable names
// the "variable" method:
$$var = $value;
// the "array" method
$arkeywords[$var] = $value;
}
You now have the "body text" in "$chapter", and either an associative
array, or the named variables of the header lines.
>3. How do i open a Word Document and extract all the text?
You might try Word2X (see http://word2x.sourceforge.net/)

You simply could have tried it - it's trivial.
The answer: no, you cannot have a constant within a string, be it heredoc
or quoted. A constant must always reside on "native code level".
However you can easily concatenate strings and heredocs - both of the
examples below work correctly:
define('A_CONSTANT', 1);
$text1 = <<$text2";
Output:
This heredoc text contains the constant A_CONSTANT (1) outside the heredoc
construct...
This quoted text contains the constant A_CONSTANT (1) outside the string
quotes...

Untested:
if (preg_match('/^http:\/\/[^\.\s]+\.[^\s]+\/$/i', $string))

else
// invalid string
Should match a string beginning with 'http://', followed by one or more
characters that are no dots or whitespace, followed by a dot, followed by
one or more characters that are not whitespace, and terminated with a
slash. The terminating 'i' makes the search case insensitive.

[snip]
A valid HTTP response is a MIME message comprised of two parts - the header
block, and the data block. Both blocks are separated by a single empty newline.
You can easily split them using something like this (untested):
list(header, body) = preg_split("/(\r\n|\n\r|\r|\n){2,2}/s", $message, 2);
This should catch all possible variations of newlines. The correct newline
sequence afaik is "\r\n".

Try echoing using htmlentities(), IE (and all other browsers) will need to

Nope - doesn't work (Apache 1.327, PHP 4.2.3). Here's a URL for you to
check this out:
http://www.vogelsinger.at/test.php
Basically the test.php offers you the choice to either virtual() or
readfile() an external file, passing URI parameters. As you can see when
using virtual() the callee has the same environment as the caller, however
using readfile() via HTTP everything works as expected.

Re: [PHP] including db content as part of script

[snip]
If you have code in your database, you don't include() it but eval() it.
Make sure though that the code is error-free (at least no fatal errors):
global $php_errormsg;
$php_errormsg = null;
$result = @eval($code);
$error = $php_errmsg;
This will execute the contents of "$code" as if it were a PHP source file.
You can even use such constructs:
// do some stuff here
?>Hello from outside PHP

Ask these guys at your webhost to move /tmp to another partition, or _at_least_ to have session.save_path point to a partition that doesn't get exhausted too quickly. God. What do these webhosts think... -- >O Ernest E.

The rest is a html or possibly css issue. If you need to get this sorted out you should try to work with a WebTV client appliance to see what's actually happening... -- >O Ernest E.
