[PHP] Faking Boolean
How can I take enquiry: input name=searchenquiry type=text value=john or input name=searchenquiry type=text value=john johnston and parse its value to come up with this to do a boolean search +john or +john +johnston Does there exist a function yet :) ?

Re: [PHP] PHP Form Help
Dear Chris,
Thank you for your response. I will make sure to start a new thread for
future.
I tried this but it did not work
if (isset($_POST['title'])) {
$title = htmlentities($_POST['title']);
echo $title;
} else {
$title = '';
}
This part of my code seems to be the problem, Though I dont know why.
if (isset($message))
{
echo font color=\red\{$message} /fontbr;
echo You are logged in $user;
?
Cause if change the if statement to
if (!isset($message))
the values are saved. But I need this to display the message..
if (empty($title) || empty($Email) || empty($Phone) || empty($Details)
|| empty($Keywords) || empty($City))
{
$message = Please fill all the required fields.;
// Now, redirect the browser to the current page
session_start();
header(Location: form.php?message= . urlencode($message));
exit;
}
Here is my structure..
?php
//check is there is any message, which I expect to have when the user
come on this page. Then show the user form
if (isset($message))
{
echo font color=\red\{$message} /fontbr;
echo You are logged in $user;
?
HTML CODE FOR FORM..
?php PHP code starts here
}//end of IF
else
{
if (empty($title) || empty($Email) || empty($Phone) || empty($Details)
|| empty($Keywords) || empty($City) || empty($State) || empty($ZIP) ||
empty($Type))
{
$message = Please fill all the required fields.;
// Now, redirect the browser to the current page
session_start();
header(Location: form.php?message= . urlencode($message));
exit;
}
here is the code to insert the entries into the database..
where it goes back to the same page for each error message
header(Location: form.php?message= . urlencode($message));
exit;
Or come back to the same page with a valid message for another entry..
}//end of else...
? end of php code
I am confused what I am doing wrong..
Again thank for your response.

You're not including the post values.
It should be something like:

? size=60..
or you could check everything before hand:

$keywords = '';

something like:

$ffelptotEQtotal = (($enumFFELP + $numFFELP) == $numTotal);

are quite repetitive (although the combination changes each time)

because I feel it looks 'nicer' and it's more compact, thats down to personal
opinion of course. something like:
switch (true) {
case $ffelpEQtotal $lendersGTone:
return array(true, 'A');
case $ffelptotEQtotal:
return array(true, 'A');

Are you in a function? Maybe it'll be clearer/easier to follow if you
return when you find the right condition:
if ($numFFELP 1 count($FFELP_Lenders) 1 $numFFELP == $numTotal) {
return array(TRUE, 'A');

PS - count($array) does a count every time, so depending on how large
you expect this array to get, it could be quicker (processing time) to:
$count_lenders = count($FFELP_Lenders);

in a function, but I prefer to only have one location of returning. I
think it makes it easier to debug.

Without seeing more code it's hard to say which would be better for you to
use, but based on the snippet you've provided it looks like an if block is
the only thing that will work for you. The main perk to using switch over if
statements is speed (Google can back this up). The reason it's faster is
because it's simpler by design and is able to jump directly to the case that
evaluates to true, whereas an if statement needs to evaluate every if/elseif
condition until it finds one that evalutates to true.
In your example you're passing the $FFELP_Lenders variable through count()
multiple times. One way to speed things up would be to cache the results of
count($FFELP_Lenders) in a separate var so that the entire $FFELP_Lenders
array isn't being counted potentially 50+ times - unless of course you're
manipulating it later in the code.
You can also clean up this code a bit by removing other redundancies. In the
example below we're only evaluating $numFFELP one time. If it is not greater
than 1 then everything inside that block that depends on $numFFELPS being
1 will be skipped - getting you one step closer to the speed of a switch
statement.
// Cache the number of elements in the
// $FFELPS_Lenders array
$numFFELP_Lenders = count($FFELP_Lenders);
if($numFFELP 1) {
// At this point we know $numFFELP is greater than one
if ($numFFELP_Lenders 1 $numFFELP == $numTotal)
$retVal = array(TRUE, 'A');
}else {
// From here on out we know that $numFFELP
// is greater than 0. If it's not this block of code
// will be completely ignored.
if($enumFFELP 0 $numFFELP_Lenders 1 $enumFFELP + $numFFELP ==
$numTotal){
$retVal = array(TRUE, 'A');
}elseif($numCONS 0 $numFFELP_Lenders 1 $numFFELP + $numCONS ==
$numTotal){
// Rob says Wh!!11!!!11one1!
}
}
It's been a long night for me as well so I hope this makes as much sense to
me in the morning as I think I does right now ;-)

up a good point. switch statements are not always faster. Here's an
example from
http://www.php.net/manual/en/control-structures.switch.php - note that
it says that in certain circumstances switch may be faster than an if.
In a switch statement, the condition is evaluated only once and the
result is compared to each case statement. In an elseif statement, the
condition is evaluated again. If your condition is more complicated
than a simple compare and/or is in a tight loop, a switch may be
faster.
Specifically the evaluation occurs only once at the entry point, but
that evaluation will occur for every iteration of an enclosing loop.
Given their comments, they are misleading in that the switch will only
be faster if you don't precompute the value to compare in your
if/elseif/else statements. For example, they are saying switch is faster
than the following:
?php
if( ($foo + $fee) == 0 )
{
}
else
if( ($foo + $fee) == 1 )
{
}
else
if( ($foo + $fee) == 2 )
{
}
else
{
}
?
Well duh! In practice, what kind of an idiot does that? (ok, ok, don't
answer that ;) However, it may be the case, that the overhead of
precomputing and assigning to a variable in PHP land is a tiny bit
slower than the internal precomputation for switch. Either way,
internally, switch behaves like if/elseif/else and generally only
provides an advantage with respect to code organization or if you want a
particular condition to drop through to other case blocks.
Cheers,
Rob.

[PHP] how to run 'periodic'
Hi. I have written a script which outputs a rather large ZIP file ( 200 MB ) by collecting a large amount of PDF files and html pages. When the script is done, the available amount of free memory has decreased by about 20 - 30%.

The question is: how can I execute 'periodic daily|weekly|monthly' from my script? Is this possible at all? I know that 'periodic' needs root. And all PHP code is executed as www user which doesn't have root privileges.

PHP doesn't automatically display anything you don't ask it to display. (Other than these occaisional 'error messages' some claim to see ;-) In your code snippet, I happened to notice that you explicitly echo the username and password. I would say the fix for this is don't do that. 3. and got to provide the time, but how do i format it say for australian east standard time? just got the standard time, and jaws reads it out, as one line of text.

[PHP] simple regex query
Hi guys
Been tryin to figure out regex and have found some tutorials but some have made
things clear and others have confused me.
Anyway for a simple query, if I just wanted to check that a variable has only
text and numeric characters would I do something like this
(i want it to fail if it finds a symbol eg: + - { etc...):
echo REG result: . preg_match('/[a-zA-Z0-9]*/', '{d-fg');
however this resolves to true because there are normal characters (alphabetical
characters) so how do I make the expression fail because of the { and -
characters in the string?
You can also list which characters you DON'T want -- just use a '^' as the
first symbol in a bracket expression
(i.e., %[^a-zA-Z]% matches a string with a character that is not a letter between two percent signs). But that would mean that I would have to list each symbol I dont want and that would be
undesireable as it would be better to list exactly what the acceptable characters are.
Can anyone give me some insight as to where I'm going wrong?
thanks

Typically, quotation marks combine multiple words into single expressions, which makes sense with John Johnston but not with John Johnston. But since you requested the quotes I'll include them: Here's one way to convert an incoming word series for a search: // get the entered text $sEnquiry = $_GET[searchenquiry]; RESULT: [ johnjohnston ] // protect against input attacks here ... // remove whitespace from beginning end $sEnquiry = trim($sEnquiry); RESULT: [johnjohnston] // replace internal whitespace with single spaces $sEnquiry = preg_replace(/\s+/, , $sEnquiry); RESULT: [john johnston] // replace each space with quote-space-plus-quote $sEnquiry = str_replace( , \ +\, $sEnquiry); RESULT: [john +johnston] // add beginning ending delimiters $sEnquiry = +\ . $sEnquiry . \; RESULT: [+john +johnston] Another technique that's worth exploring uses explode implode to isolate the words and the join them again with different delimiters, e.g.: // remove extraneous whitespace $sEnquiry = ... // split string into array of words on each space $aWords = explode( , $sEnquiry); RESULT: array( john johnston ) // concatenate the array back into a string using desired delimiters $sSearch = implode( +, $aWords); RESULT: [john +johnston] Paul -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

however this resolves to true because there are normal characters

of the { and - characters in the string?
You can also list which characters you DON'T want -- just use a '^' as
the first symbol in a bracket expression
(i.e., %[^a-zA-Z]% matches a string with a character that is not a
letter between two percent signs). But that would mean that I would have
to list each symbol I dont want and that would be undesireable as it
would be better to list exactly what the acceptable characters are.
Can anyone give me some insight as to where I'm going wrong?

[PHP] Color matching magic?
I'm trying to figure out if there's a tool that can do this (programmatically) or if someone has some script idea/suggestion for what I'd like to do.

I'd like to have a script run that will read in the folder(d) where these images are stored and with ImageMagick, create a montage of them. I need to be able to set how many images wide by how many tall I'd like it to be, and I'd also like the script to organize the images in a rainbow pattern based on their color. Very much like what a PhotoMosaic program would do with images, create a color index of each one, then build a larger image with these little ones.

You're pretty much there. Your first example resolved to true because
you didn't anchor the start and end of the expression.
/^[a-z0-9]*$/i
It would be a bit more efficient to use the negated character class
you mentioned.
/[^a-z0-9]/i
All you need to bear in mind is that preg_match() would then return
true if the string contains an illegal character and false if it is OK
rather than the other way around.
So these should both produce the same result:
preg_match('/^[a-z0-9]*$/i', '{d-fg');
!preg_match('/[^a-z0-9]/i', '{d-fg');

JavaScript. But I won't bore you with the exact way of doing it,

use gmdate() to format it into human-readable format. If you want to
adjust it to your time, simply add your GMT offset to it, making:
gmdate('d-m-Y', time()+(10*60*60));
This adds 10 hours (10 hours x 60 min x 60 seconds) to your base GMT
timestamp, and then formats it. Not sure how big the offset it for
Australian East standard time, but it'll be something between 9 and 11
hours.

Although there are some directives worth disabling (register_globals, magic_quotes_gpc, allow_url_fopen), most vulnerabilities in PHP applications are a result of flaws in the PHP code. There are no magic php.ini configuration directives that can make your applications secure - not that you were suggesting this, but it's woth explicitly stating. A couple of years ago, I tried to summarize several good practices into a single mantra - filter input, escape output (FIEO). These practices don't eliminate everything, but they're a very good first step and can provide a solid foundation for secure PHP programming. I made a movie (webcast, screencast, or whatever you call them) about auditing PHP applications, and it also covers filtering input and escaping output: http://brainbulb.com/php-security-audit-howto.mov There's also the PHP Security Guide: http://phpsec.org/projects/guide/ We're in the process of writing a second version of the guide, in order to address the following shortcomings: 1. The guide is several years old, so some techniques have been refined and/or simplified in the meantime. 2. The vocabulary is slightly inconsistent with the rest of the industry in some cases. 3. Not all major areas are covered, so it is incomplete. 4. Some explanations are ambiguous and can yield misinterpretations. Lastly, I want to point out two of the primary attacks that are not prevented with FIEO: 1. Cross-Site Request Forgeries (CSRF) 2. Session Fixation Hope that helps get you started.

Hi guys
Been tryin to figure out regex and have found some tutorials but some have
made things clear and others have confused me.
Anyway for a simple query, if I just wanted to check that a variable has
only text and numeric characters would I do something like this (i want it
to fail if it finds a symbol eg: + - { etc...):
echo REG result: . preg_match('/[a-zA-Z0-9]*/', '{d-fg');
however this resolves to true because there are normal characters
(alphabetical characters) so how do I make the expression fail because of
the { and - characters in the string?
You can also list which characters you DON'T want -- just use a '^' as the
first symbol in a bracket expression (i.e., %[^a-zA-Z]% matches a string
with a character that is not a letter between two percent signs). But that
would mean that I would have to list each symbol I dont want and that would
be undesireable as it would be better to list exactly what the acceptable
characters are.
Can anyone give me some insight as to where I'm going wrong?
thanks

Okay, I finally finished hashing out all the logic for a very complex set of

you with the details of it, but the question is...
I have 57 if/elseif/else statements because of all the different criteria. Is
it considered better programming practice to use if/elseif/else statements
over a switch(true) case (true false || true || false) syntax?
Basically, I'm not too happy with the readability of the code, but I'm afraid
that at this point there's not much I can do...
code snippet:
if($numFFELP 1 count($FFELP_Lenders) 1 $numFFELP == $numTotal){
$retVal = array(TRUE, 'A');
}elseif($numFFELP 0 $enumFFELP 0 count($FFELP_Lenders) 1
$enumFFELP + $numFFELP == $numTotal){
$retVal = array(TRUE, 'A');
}elseif($numFFELP 0 $numCONS 0 count($FFELP_Lenders) 1
$numFFELP + $numCONS == $numTotal){
etc.
Any suggestions?
Switch.
Regardless of speed, I find that switch is much easier to write and
debug than if/elseif -- which, regardless of my shortcomings, I never
use.
I can't stand using elseif's and have never ran into a problem that
required their use -- can anyone show me one where a switch would not
do just as well, if not better?
As for the above, what's wrong with the following?
$who_cares = 1;
switch ($who_cares)

Here are two seemingly contradictory bits of advice:
a) Spend more time making your script easy for humans to read than
you spend trying to make it machine-friendly. Servers are bloody
fast and will process your complex set of If-tests faster than you
can click your mouse. Script languages like PHP are purely for the
benefit of us humans; they're easier for us to read and write than
binary machine language. You might be able to slow down a server
with excess disk access and enormous memory demands, but I wouldn't
lay awake at night worrying about how to shave a few thousand machine
cycles off your code. Instead, think of someone (perhaps yourself)
six months or six years from now trying to make sense of your
code. Comment prolifically, name your variables and functions
sensibly, and use plenty of whitespace.
b) Still, there's something to be said for elegance in code-writing,
and efficiency as an aesthetic goal even when it's not a practical
issue. Since you're using it so much, count your array size once and
keep the result in a variable. The computer may or may not be
significantly affected but your code will be much cleaner.
That said, one thing to keep in mind with regard to conditional
processing is that PHP will stop processing a complex conditional if
the conclusion is determined early on. Consider this:
if ($bCondition == true || count($aThings) 1)
If $bCondition is true, the entire expression will evaluate true, so
it's not necessary for the script interpreter to evaluate
count($aThings) 1.
Therefore if you're concerned about processing speed efficiency you
can improve things by putting first the expressions that will
evaluate more quickly or will eliminate the most possibilities.
Here's a little program that demonstrates this point:
if (2 == 2 say(this will appear))
{
say(test 1 = true);
}else{
say(test 1 = false);
}
if (1 == 2 say(this won't appear))
{
say(test 2 = true);
}else{
say(test 2 = false);
}
function say($msg)
{
echo p$msg/p;
return true;
}
OUTPUT:
this will appear
test 1 = true
test 2 = false
The expression this won't appear does not appear because PHP stops
evaluating the second if-test after determining 1 == 2 to be false.
My surmise is that the parser first reduces the syntax to if (A
B) so it knows the number of expressions and their Boolean
relationships, so that when it begins evaluating the granular
expressions in sequence it knows when the overall conclusion is determined.

Paul

[PHP] Argument passed by reference?

thnx,
Chris
The way I understand it, pass by reference in php is determined in the
function definition and not the function call. Something like:
function foo ($bar) {
...
}
Here's a link to that section of the php manual:

Hope that helps.

The way I understand it, pass by reference in php is determined in the function definition and not the function call. Something like: You used to be able to pass by reference at run time.

[PHP] Bug Apache/PHP/Oracle on Debian
Hi, I have a server with Apache 2, PHP 5.1.1 and Oracle Instant Client 10.2.0.1. As I have a little bug [http://bugs.php.net/bug.php?id=29779], I've tried the solution (in oci8.c) and recompiled ! But then, everything was broken. So, I get the source of PHP 5.1.2 and recompiled again. Everything seems ok, with Apache and PHP, but it was impossible to use oci !!! I thought about an environment problem (LD_LIBRARY_PATH), but after some manipulations, I can see this variable in phpinfo(), but nothing about oci8 !!! I've looked into logs but I couldn't find any problem. It was like Oracle was not installed !!! So, I am completly blocked !!! Do you have any idea ? anu clue ? Thank you very much.

[PHP] how to kill session id without closing the window?
Hi to all, session_start(); $_SESSION['sessid'] = session_id; echo $_SESSION['sessid']; will show e.g. 699e506bd42ea402985dce24a0ef9 After: unset($_SESSION['sessid']); $_SESSION['sessid'] = session_id(); I'm getting the same SID again. I tried with session_unregister() and session_destroy() but same result. How can I create new, other sesssion id (after I, for example, click on 'Log Out' button) without closing window?

http://www.phpro.org/benchmarks/if-switch-benchmark.html
Hazardous is right. That's a terrible benchmark. Could have eliminated
hundreds of sources of skew by running the iterations at the command
line. It even does an echos *lol*.
I ran the following as two shell scripts, 10 times each and averaged the
times to get that switch is faster by 0.00122 secs. Big whup, as I
said in a previous post, that's very likely due to the precomputation
being assigned in userland PHP versus the internal engine. As for which
one is best, that's just flamebait -- right up there with preferred
braces style, tabs or spaces to indent, top post versus bottom post
*teehee*, etc. Personally I prefer if/elseif/else for a moderate number
of conditions or if the conditional expressions are very complex. Switch
I generally use for a large set of constants. They both have readability
pros and cons.
Cheers,
Rob.
