"some comment" wouldn't even be looked at. PHP sees the //, and goes to the next line.
I suppose on a large scale this could reduce performance, but the performance that is lost in standard applications is minuscule.
One thing you might want to avoid is using comments inside loops.

An answer proposed that there was little impact, but then suggested comments not be used within loops (one presumes from this, the concern is that even a little impact can mount up when repeated many times). Why don't you run a microtime testbench to time a commented and an uncommented loop, settle your mind, and report back with REAL information!? Computer programming is the embodiment of 'write once, run many' manta. Comments are no use at all during execution, but should be intended to be of considerable assistance during the writing/maintaining phases. Never give anyone an excuse for not writing (meaningful) comments - enough energy already goes into creative excuses for that - and you may be the next to suffer from some predecessor's arrogance! There are routines available which take in a developer's script and output a comment-less, stripped-down for maximum slipstream, dense code, version - ready for execution.

As PHP is an interpreter it needs to scan every line and every token of
code as it runs it. Thus said, of course using comments takes more time to
execute than having no comments.
I have no profiling yet how much having comments or blank lines would
actually effect execution times, but I doubt it would be really an issue
since PHP, once a comment start is encountered, doesn't parse the text but
just scans for the end-comment tag.

Some time ago I've made myself a framework for such tests and have run it
against a commented loop. This test was run on a dual PIII/1000 Dell server.
$hpr = _fwx_profile_start('Loop with end-of-line comment', true);
for ($i = 0; $i < 1000000; ++$i) {
$a += 1; // this is an end-of-line comment
}
_fwx_profile_end($hpr, $i);
Average time per loop: 0.059 msec
$hpr = _fwx_profile_start('Loop with inline comment', true);
for ($i = 0; $i < 1000000; ++$i) {
/* this is an inline comment */ $a += 1;
}
_fwx_profile_end($hpr, $i);
Average time per loop: 0.059 msec
$hpr = _fwx_profile_start('Loop without comment', true);
for ($i = 0; $i < 1000000; ++$i) {
$a += 1;
}
_fwx_profile_end($hpr, $i);
Average time per loop: 0.059 msec
Conclusio: I didn't find any measurable difference in these loops, be it an
end-of-line comment, an inline comment, or no comment.

=Apologies: I hit 'Send' on the preceding msg, even before signing off...
Duh!
=I have a similar test bench/frame, but which only puts out microtime
differences. My personal/dev PC is an Armada portable with 266MHz processor
and so is considerably more modest than your own beastie.
=I find that because the wee beastie is running PHP, Apache server, MySQL
server, etc, etc; that multiple runs of the same code can yield considerable
differences in execution time - see also warnings in manual, eg 'caching'.
Accordingly I run six cycles and record the last three:
=Herewith:
End of line comment: 4.3118, 4.415713, 4.342078
Inline comment: 4.331843, 4.403446, 4.339082
Loop without comment: 4.415728, 4.399776, 4.420114
=however a quick analysis shows that the fastest-slowest differences are:
.104, .072, and .021 (secs, resp)
=the differences between test types run to:
slow end: .012, and .017
fast end: .020 and .068
=In other words, apart from the first set of tests, any and all differences
are insignificant/disappear into 'noise'. However, if the "Loop without
comment" results make sense to you - you're a better man than I, Gunga Din!
=Concur completely with your own analysis,

If you're worried about the extra lex/io time on your scripts then (besides being a little insane :), you should just be using a cache like the PHP Accelerator or APC, which will make comments give you absolutely no performance hit. -Sterling--- End Message ---

If the overhead of the parser removing comments becomes an issue for you, you'll probably be in the situation where your application is heavy, with thousands of scripts, and a lot of commenting everywhere. As said before, the comments only impact the parsing. So, you just have to implement a "stripcomment" script, that you run when you move your script from your development server to your production server. And anyway, this would not be significant, unless you recompile a custom PHP version where you remove the comment parsing. This would be intereting if your code was already optimized...

Hi all,
Need a little help here been at this for a while now...
I have a database holding a table which in turn holds a collection of fields
I need to search.
Ive set up search form that sends the variable $S_For and $S_From, these
variables represent the following:
$S_For = the search keyword itself
$S_From = the column which I need to search
Ive created this and it works fine for single words, the problem as you may
of guessed is when I enter a string of words ie:
apple - works fine
orange - works fine
apple orange - doesnt
Any help would be ideal!!!!
-----------------
Databse = clientacc
Table = hospitality

Hello,
What you need is :
1- parse your query and make it boolean
"apple orange" become "apple and orange" and so on
2- then you can generate a MySQL query based on that like this way
-----------
SELECT id, field1
match (field1) against (' apple orange ') as relevance
FROM hospitality
WHERE
match (field1) against ('apple')>0 AND match (field1) against ('orange')>0
HAVING relevance>0
ORDER BY relevance DESC
-----------
field1 will be your field(s) you're searching in.
Hope this will help

--- Begin Message --- You first need to separate the words and then build your query:
$words = explode(' ',$S_For);
$cond='';
foreach($word as $str) {
$cond .= " $S_From LIKE '%$str%' AND "; // replace AND with OR if you want ANY word
}
// remove trailing AND(last 4 chars) or OR(last 3 chars)
$cond = substr($cond, 0, strlen($cond) - 4); // this is for AND
And I hope you check the value of $S_From if it is valid

--------------------[snip]--------------------
No, that's a misunderstanding. Session var's are never passed to and from
the client, only the session _name_ is passed, either via a cookie
(PHPSESSIONID) or via trans-sid href encoding.
Session vars are kept server-side in session storage, which is (by default)
a file located in the directory where session.save_path is pointing to. The
default file name is sess_<session-identifier>. The client only transmits
the session identifier so the server is able to correlate a session to a
particular request.
What I did for this particular application was to extend the system with a
cookie that's programmatically sent, using a random cookie name and a
random cookie content. Thus I am able to distinguish between multiple
logical sessions using the same session identifier, a scenario that could
happen when a URL containing a trans-sid has been bookmarked or transfered,
or when the client had opened a new window within the same session and
continued in "split mode".
Whatever the client passes to PHP as a cookie you can access in the
$_COOKIES array. Whatever PHP has stored in session storage can be accessed
in the $_SESSION array. They are quite different.

I'd leave it as is... this ensures that ALL users can use the site, because the session id can be passed around in either the URL or cookies... and enabling trans sid means you don't even have to worry about it... PHP will use cookies if possible, or else append it to the URLs. What sort of stuff are you storing in the session that your are worried about with too many writes?

For each open session I store up to 20 variables. It's not a lot, but each access to a script means a disk read/write so they will eventually add up if there are enough users.
Of course this problem goes away if you throw enough money at the hardware ...

Why would you do that? session data is read and decoded once from a LOCAL
file, while transmitting all session data over a REMOTE line would be much
slower. Further it's MORE than insecure to hand possibly sensitive session
data to the client where any bad guy might tamper with it and harm your
application. Lastly cookies are limited to a certain size of data (I
believe it's 1k but I don't know exactly).
Use sessions as intended, it's a very well tested and very fast way to
create a persistent state across multiple subsequent connections.
If you don't like the file approach you can always invent your own session
handling system, be it database-driven (which would be even slower), or
some kind of session-server process that runs locally and gets contacted by
the applications, or even some shared memory... choose your ways, but keep
your data at the server's.

Assuming you're running a server operating system (either Linux, or other
X, or even Win2K _server_) disk i/o gets already greatly reduced by the OS.
Any server OS implements its own decent file i/o cache that leverages
repeated disk i/o transparently. I wouldn't bother about that too much.
What you should keep in mind that the OS needs enough memory to build up
its decent cache. Which would mean that you plug in more memory banks the
more users you have. If you suspect your server is slowing down because of
disk i/o why not run a realtime performance log to see where bottlenecks
are, and to act accordingly then?
My experience shows that file session storage is the very last bottleneck
that ever would occur; the database times add up much quicker than any
session file i/o would ever be able to.

Having a DB based session handler comes in very handy when you are troubleshooting a new session-based application.

There are two reasons why you should not consider such a rewrite: 1. performance 2. security You say you want to pass data as cookies to save your server the latency of disk access. Think about that for a moment, and you will see that it makes no sense. This is similar to making a decision to store all of your data on a remote FTP server rather than your local disk, thinking that this somehow saves you time. Regardless of how much bandwidth your network has and how slow your disk is, there is no way transmitting this data to/from the client across the Internet is going to be faster than local disk access. Floppy access is probably not even as slow as what you are considering. A more important reason to avoid the rewrite you are considering is security. A cookie is sent by the client. The client can be anyone using your site. What if the client is trying to circumvent your site's security in some way? Do you really want to trust everyone who visits to be honest? When you set a cookie, you are asking the client to send that cookie (value unchanged of course) in future requests. There is nothing aside from honesty that keeps a client from changing the cookie. Also, cookies are intended as a mechanism for maintaining state. This means that they are well-suited for helping you identify a client (the Web browser). Session management requires a little bit more, and this is where PHP sessions come into play. Cookies are a poor choice for session management (state management + maintaining client data), and this is what it seems like you are considering. Chris--- End Message ---

I can think of no security reason why you would want to allow anyone to
display output from a command, but wouldnt want them to be able to assign
that output to a variable. Can someone explain a situation where that would
be useful? Arent any security concerns addressed by the safe_mode_exec_dir=
directive? Is there any way to get the safety of safe mode without this
seemingly backwards rule? [If I was a malicious user with the ability to
upload a script, I certainly wouldnt be at all hindered by being unable to
have the script itself parse the output- I'd get a seperate script to do that
for me and POST the results back to the server's script just as fast.]

--- Begin Message ---Hi all, I've been working with php for a while and whenever I have the chance I give some tutorials/speeches about it to other developers, specially those with no experience with web development. They all find easy but in one point or another start asking about an IDE with a debugger, variable watch etc or RAD tools (they come from Visual Basic/Delphi enviroments). In the IDE part I know we have some paid tools (such as Zend) but can't tell anything that could count as RAD tool. So, I'd like to know if there are any RAD tools , either free or paid that you know. One thing that I am planing to develop, or enhance if I found something similar already, is a form "parser/validator". Suppose your design department comes with a real nice html-css-form and you need to validate it, send the content as email or add in a database. This tool would read the HTML and prompt you for the optional/required fields, validation options (minimum/max length) etc, send via email or add in a database.. Then would generate the php code to validate and perform the required actions. I think there is a classe (from manuel lemos) that does soemthing similar but also generate the form itself based on a definition. What do you thing about it ? The ideia is to speed up the repetitive/boring stuff leting the developer focus on special logic - usually restricted to fewer options. __________________________________________________ Do you Yahoo!?

If the script is called via command line, at least these fields in the
$_SERVER array are empty/unset:
SERVER_NAME
REMOTE_IP
I don't even know if the $_SERVER array is set at all.
You can disable any PHP script to be run from the command line by setting
the appropriate file permissions (e.g. chown root:apache, chmod 640 *).

and BLOB is like TEXT, except for comparison is case sensitive in BLOB.
And what if the file contains malicious code - it might come from remote user's upload

The only similarity I can think of is that they both represent data. However, the format is completely different. Open up a binary file in a text editor, and then do the same with a regular text file. I think you will notice a significant difference. Or, consider the representation of 16 in binary versus ASCII: binary - 10000 ascii - 0011000100110110 As Sterling mentioned, using addslashes() on binary data is a bad idea. The same can be said for any string operations intended for ASCII data. Chris--- End Message ---

Caching is usually managed through a set of headers--for example:
<?php
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT"); // Date in the past
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
// always modified
header("Cache-Control: no-store, no-cache, must-revalidate"); //
HTTP/1.1
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache"); // HTTP/1.0
?>
You can use these in the pages that are dynamic and omit them in those
pages where you want to keep the information.
Cheers,
Marco

Also, how could I then limit how many are in the post? > ----- Original Message ----- > From: "Tom Culpepper" <[EMAIL PROTECTED]> > To: "Stephen" <[EMAIL PROTECTED]> > Cc: "PHP List" <[EMAIL PROTECTED]> > Sent: Saturday, November 23, 2002 9:46 PM > Subject: Re: [PHP] Parse URLs > > > > from the archives of the list > > http://www.phpbuilder.com/mail/php-windows/2001042/0222.php > > > > -tom culpepper > > > > > > Stephen wrote: > > > 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. > > > > > > > > > ----- Original Message ----- > > > From: "Tom Culpepper" <[EMAIL PROTECTED]> > > > To: "Stephen" <[EMAIL PROTECTED]>; <[EMAIL PROTECTED]> > > > Sent: Saturday, November 23, 2002 9:05 PM > > > Subject: Re: [PHP] Parse URLs > > > > > > > > > > > >>not entirely sure what is going on there, but if the user is entering > > >>the url in a html form.

--- Begin Message ---Hello, I have PHP v4.2.3 on Windows 2000 Advanced Server with Microsoft SQL Server v7.0, and a script for domain registration via OnlineNIC. That script uses cookies to maintain session information, but it seems it can't store those cookies on the hard disk so it always asks me to login in every page. I changed any related options and settings in php.ini (according to my knowledge of course) but the problem persists. Would someone please help me? Thanks in advance. Omid--- End Message ---

In the purpose of getting access to mydomain.se/ha/ I will set a cookie:
setcookie ("login", "OK", time()+3600, "/ha/");
It looks like the cookie is set since I get the confirmation text (of course
placed inside the codeblock where the cookie is 'set' (?). Probably it just
confirm that it has found ONE hit in the db on the username/password pair).
But, when I try to access any file in mydomain.se/ha/ it fails and the login
script is loaded again (and a look in 'Temporary Internet Files' tells the
cookie doesn't exist). On the local machine (w2k, apache 2) the same script
works ok
