The first includes the file directly, the second makes an http request

Don't do that - publishing your passwords on the internet is rarely a
good security policy.

Move your include directory out of the document root, then include the
file directly. It'll speed things up too.

Combine query1 and query2 into a single query by using a join rather
than repeating query2 for every single row of query1 - it should save
you 20-odd database queries per page request.

Please note you are quoting from an RFC with the following title:

Uniform Resource Identifiers (URI): Generic Syntax

Pay special attention to "Generic Syntax" in the title.

The RFC linked by Richard clearly indicates that for the Location
response-header that "the field value consists of a single absolute
URI". This currently has the final word for the Location response-header
and therefore is the standard.


What?

Pay special attention to what I wrote.

I wasn't disagreeing with Richard, or the RFC he quoted. The OP
expressed some confusion about what comprised an 'absolute URI' so I
quoted the section of the RFC that defined an 'absolute URI'.

There's no question that a Location header should contain an absolute
URI as its value.

Although I always use a full URL as well, doesn't absolute just mean
non-relative? As in:
Location: /Protocols/rfc2616/rfc2616-sec14.html#sec14.30
(absolute URI)

Location: ./rfc2616-sec14.html#sec14.30
(relative URI)


If you need contextual information to make sense of the URI (such as
the server name from a previous request) then it's not absolute.

RFC 2396: Uniform Resource Identifiers

"An absolute identifier refers to a resource independent of the
context in which the identifier is used. In contrast, a relative
identifier refers to a resource by describing the difference within a
hierarchical namespace between the current context and an absolute
identifier of the resource."

I'd look at the text that you're working on rather than the regexp. It
looks like some characterset conversion is going wrong - 0xA0 is the
latin-1 non-breaking space character. I'm expect that on your linux

perfectly valid in a URL.

Holy !!!

I've used regexps for quite a while now, but won't even begin to read
that. I use:

/^(ht|f)tps?:\/\/([0-9]{1,3}(\.[0-9]{1,3}){3}|([0-9a-z][-0-9a-z]*[0-9a-z]\.)+[a-z]{2,4})\/?[%&=#0-9a-z\/._+-]*\??.*$/i

to match an full URL with domain name or IP address, and:

/((ht|f)tps?:\/\/([0-9]{1,3}(\.[0-9]{1,3}){3}|([0-9a-z][-0-9a-z]*[0-9a-z]\.)+[a-z]{2,4})\/?[%&=#0-9a-z\/._+-]*\??[^[:space:]]+)/i

to replace an space delimited URL with preg_replace.

It has worked fine for me, but I just can't read your regexp, so I can't
see why it's better.


Depends what you want it for - the Regexp::Common expression is
precise - it matches a well-formed http or https URI, nothing more or
less. It's also used in thousands of perl applications through
Regexp::Common and has been extremely thoroughly tested.

Yours is an approximation - it probably works fine for this kind of
job, but it will make mistakes at times.

For instance - if the OP is trying to display html source with the links live:

$text='<a href="http://www.example.com">this is a link</a>';

The Regexp::Common expression just matches the URI, whereas yours
matches all the way through to the end of the word "this".

Show us some examples of URL substrings, with any variations, you want to 
handle.

Most likely a regex function will do the job.


In 6 easy steps:

Step 1: Pinch  a regexp from perl...

 perl -e 'use Regexp::Common; print $RE{URI}{HTTP}, "\n";'

Step 2: Double up all backslashes

 M-x replace-string \ \\

Step 3: Escape single quote-marks

 M-x replace-string ' \'

Step 4. modify slightly to cope with the https scheme by adding an
optional 's' to the http scheme.

Step 5. add angle-brackets as delimiters

Step 6. use in a preg_replace()

http://example.com  imperdiet nec, tempus ac, purus.
Suspendisse id lectus. Nam vitae quam. Aliquam ligula nisl, vestibulum
vulputate, tempor nec, https://www.example.com  tincidunt sit amet,
libero. Suspendisse a justo. Cum sociis natoque penatibus et.';

$url_regexp = 
'<(?:(?:https?)://(?:(?:(?:(?:(?:(?:[a-zA-Z0-9][-a-zA-Z0-9]*)?[a-zA-Z0-9])[.])*(?:[a-zA-Z][-a-zA-Z0-9]*[a-zA-Z0-9]|[a-zA-Z])[.]?)|(?:[0-9]+[.][0-9]+[.][0-9]+[.][0-9]+)))(?::(?:(?:[0-9]*)))?(?:/(?:(?:(?:(?:(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*)(?:;(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*))*)(?:/(?:(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*)(?:;(?:(?:[a-zA-Z0-9\\-_.!~*\'():@&=+$,]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*))*))*))(?:[?](?:(?:(?:[;/?:@&=+$,a-zA-Z0-9\\-_.!~*\'()]+|(?:%[a-fA-F0-9][a-fA-F0-9]))*)))?))?)>';

Re: [PHP] The difference between ereg and preg?

On 04/08/06, Dave M G <[EMAIL PROTECTED]> wrote:


It seemed that the main difference was that preg_replace required
forward slashes around the regular expression, like so:
preg_replace("//", "", $htmlPage);


It requires delimiters - slashes are conventional, but other
characters can be used.



But that didn't work, and returned an error.


What you've written here shouldn't return you an error - what did the
message say?

I suspect you were trying to match until  rather than  and
the pcre engine thought the forward slash was the end of your regular
expression.


Part of that code deleted all the unwanted text from the very top of the
page, where it says "" tag.


It won't quite do that.

The (.*) matches as much as possible (it's called greedy matching) -
so it'll match and replace all the way down to the *last* instance of
a "" tag.

To make it match for the shortest length possible, put a question-mark
after the ".*" like so:

  preg_replace("//", "", $htmlPage);


Since ereg was working, though, I figured I would just stick with it.

Still, I thought it worth asking:

Is there any reason why either ereg or preg would be more desirable over
the other?


pcre has a performance advantage, has more features and can use the
many regexps written for perl with few or no changes.

ereg is a posix standard.

There's no "hiding". You could use a secure key exchange mechanism, such
as Diffie-Hellman.

Diffie-Hellman is used to generate a shared key between two hosts (say
"A" and "B") such that each host knows the key, but any third party
listening in on the information is unable to trivially reconstruct the key.

See: http://en.wikipedia.org/wiki/Diffie-Hellman


How about if the third party can control one side of the transaction
by altering the javascript that implements it while in transit -  for
instance by adding a couple of lines that transmit the key to the
third party after the key exchange?

I don't think the author does not know how to handle multidimensional
arrays. I thought the author was more concerned about performance than
other issues people like as coding "beautifuly"...  Maybe author's
approach is weird, but its twice faster in the worst case!!

Sure the author only needs to loop the whole array and doesn't need
multi-dimensional approach... 'cause its a lot faster to iterate once
the array is filled!!

Look at the test I've done (below) its seems filling multi-dimensional
arrays is n/2 faster than single dimension, but then when you need to
read the array data, a multi-dimensional approach is always worse than
n*6!!


Your setup is odd. I get much more similar results with both php 4 and 5.

You're also using a more than slightly odd way of iterating through the array.

These does exactly the same as your Test functions and are considerably faster:

 $v) {
   foreach ($v as $k2 => $v2);
 }
}
?>

Test results from PHP 5.0.5:

Fill style A, bidimensional array: 3.0747
Iteration style A, bidimensional array: 2.4385

I notice that the 'sh' shell is being used according to your error output,
I'm guessing that maybe your interactive shell is running something like 'bash'
and that this discrepency might the root cause of the problem. just a guess -
I don't know how you would define another shell for php to use either :-/.


That's exactly what's causing it.

One thing the OP can do is invoke bash to run his command line:

  $cmd = '/bin/bash -c  "paste <(cut -f1 file1) <(cut -f2 file2) > file3"';

Alternatively, arrange the command line more efficiently:

  $cmd = 'paste file1 file2 | cut -f1,6 > file3';

(replacing the '6' with the correct field number)

Yeah, two items of information in the same column's not really a good
idea, which is why you're finding it so tricky.

So what you can do is this:

SELECT title,
   LEFT(title, LENGTH(title) - LENGTH(SUBSTRING_INDEX(title, ' ', 
-1))) AS name,
   CAST(SUBSTRING_INDEX(title, ' ',  -1) AS UNSIGNED) AS number
FROM $dbtable
ORDER BY name, number;

So that's finding the position of the last space and putting
everything up to that in `name`. Then it's taking everything after
that, turning it into an integer and putting it in `number`.

Then the ORDER BY works as you'd like because it's sorting on an
actual number rather than a string representation of a number.

If you'd had the name and the number in separate columns in the first
place it would be so much simpler.

Yes - that's the default behaviour, although if you set
session.cookie_path separately for each app, they shouldn't share
session cookies. You might also want to look at session.save_path
which will allow each app to save their session files in a different
location.

Firstly, you're assigning "a" to area rather than testing whether
$area is "a". You need a "==" operator, not a "=".

Secondly, even if you were testing $area properly, you're doing the
same thing in both halves of the if-statement. Which isn't very
useful.

Really, you only need the "AND area='?'" part if $area is not equal to "a":

if ($area != "a") {
   $query1 .= " AND area='$area'";

So use the built in tokenizer functions which know exactly what's

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');

You'd be much better using the interface to Net_Ping_Result that's

$ping_result->getMin();
$ping_result->getMax();
$ping_result->getAvg();

There are no open bug reports for array_search(). Loads of bogus ones though.

array_search() also completely the wrong tool for the job - the code
you posted is much more complicated and slower than it needs to be.

That whole palaver that you go through to produce $reduced could be
replaced with:

   $reduced = array_merge(array(), array_unique($str));

That nested loop you use to produce $final would be rather simpler and
faster if you just flipped $reduced and used a hash lookup.

   $charmap = array_flip($reduced);
   foreach ($str as $char) { $final[] = $charmap[$char]; }

The technical limit per directory in ReiserFS is slightly more than
half a billion files. Although with the standard hashing function the
practical limit is about 1.2 million. Would you like to hazard a guess
about MySQL's performance with 1.2 million images in the same file?

MySQL stores each table in it's own file which is subject to the
filesystem size limits. For example the maximum file size in ReiserFS
3.5 is 2 Gig. So ignoring all the overheads, to fit more than 1.2
million images in a table, they'd have to average rather less than 2kb
in size.

Each of these images is likely to be a different size so you're stuck
with variable length records, which has a significant performance
impact in MySQL. It'll also result in gaps in the file which will
further restrict the amount you can get in there.

You'd better make sure your indexing on the table is good, because a
sequential scan over that amount of data will give your disk IO a good
workout.

If you'd kept all your files in the filesystem you'd be able to
leverage all the efficient tools honed over the years to manipulate
them, and copying them to another server would involve just a simple
rsync.

If you need to associate the files with a particular record, all you
need to do is store the filename. It's not rocket science.

At the physical level, you're correct; It's all just binary data. At
every other level there's a big difference between using the
filesystem directly and bunging everything in MySQL.

Normally it doesn't matter if you define a function before or after
you use it., but you're defining the function conditionally - if
$_POST['Submit'] isn't set then recover_pw() will not be defined. In
that case you have to make sure it's defined before it's used.

The manual tells you that.

   http://au.php.net/manual/en/language.functions.php

The solution is to take the function definition out if the if-block.

Yeah, but it should be $conn, not conn.

PHP treats conn as an unquoted string which evaluates to true, so it's
quite possible that your mysql_connect() is failing and you're not
detecting it.

$ php -r 'if (conn) print "Connected...\n";'
Connected...

You're not checking that you've managed to open the file - if you've
got error_reporting turned down low then you'll miss the warnings from
that.

You've also got problems with the while($funct_var) loop - that return
statement is all that's stopping it looping infinitely and it's still
almost certainly not what you want.

It's more likely that you've got whitespace before or after the

 Try trimming the region before passing it to in_array().

It's not.

1. It only works with register_globals turned on. Not a good idea -
register_globals has been off by default for some time now, for good

2. There's a Cross Site Scripting vulnerability where you're echoing
out the contents of $QUERY_STRING.

3. There's an SQL Injection vulnerability where you're inserting
$username directly into the query without any validation or escaping.

4. You're keeping the passwords in the database unencrypted rather
than using a one way hash which is bad in itself, but then you're
storing also writing them to the session - if you're on a shared
server, it's likely that any other site also on that server is able to
read your session files.

5. You're checking the username and password on every page request -
even after a successful login... which isn't really a security
problem, just wasteful.

By default a '.' matches any character except for a newline. If you
want it to match *everything* you have to use the 's' pattern modifier
- just stick an 's' on the very end of your pattern, after the 'i'.

This is probably the simplest way of doing it; write a simple function
that translates entity names to numbers, then start an output buffer
at the beginning of your script using the function as an output
callback function. Then everything after that automatically gets
converted.

In fact it's so simple, I'll do it for you...

The var_dump($res) we asked you to insert output "NULL". That means
that $res was undefined.

$res is only defined within your loop and your loop is only executed
if the search comes back with at least one result.

So what you need to do is make sure that $res is an array, even if
there are no results from your query. You do this by initialising $res
to an array before the loop, just like you've done to $i.

All you need to do is add one line, just before the start of the loop that says:

   $res = array();

That's not entirely fair. I would have said his usort() suggestion was
a better pointer than a link to count() - which gives no hint as to
how to sort the list, which is after all what the OP's trying to do.

ObSuggestion:

function byLength($a, $b)

   return sizeof($a) - sizeof($b);

usort($rgArray, 'byLength');

Yeah, sure.

So you know $res *isn't* an array, which is why you're getting the
warning that  "The argument should be an array".

So you need to find out what *is* in $res, which is why I suggested
the print_r().

Now do a var_dump($res) and see what *is* in $res. Then you'll have to
work out *why* it's not an array - and the answer to that is somewhere
in those 300 lines of code you can't post.

The few lines at the end of the loop seem to be treating $res as an
array. But as it's *not* an array, either those lines aren't being
executed or you've initialised $res to something silly beforehand,
like a string.

Put a print_r($res) above this line and see what the contents of $res
are. Whatever it is, it's not an array.  Probably because your mysql
result set is empty and you forgot to initialise $res before you
looped through it (assuming the junk above is the tail end of a loop).

Doesn't work on Linux in what way?

Have you tried printing out $sql? Does it contain what you expected?

Does the mysql_query() succeed? what does mysql_error() tell you about
what went wrong?

I'd be absolutely amazed if time() really doesn't work.

I'm *guessing* that as you're running stripslashes() on these
variables, you're running your local machine with register_globals set
on, but the Linux machine has register_globals turned off.

The rules are simple enough, and listed in the documentation here:

http://www.php.net/manual/en/language.operators.comparison.php#AEN4390

But if you apply those comparison rules to your four expressions,
you'd expect to see

bool(true)
bool(false)
bool(true)
bool(false)

What you need to know to explain your results is that internally, PHP
doesn't do a greater-than comparison, it converts them into
less-than-or-equals by reversing the values. So your expressions
become:

$a < $b
$b <= $a
$b < $a
$a <= $b

Now if you apply the comparison rules to your arrays using those
rewritten operations, you get true every time.

Fun eh?

As Curt said, it's probably better to do this programatically - if
only so you can work out what it's doing six months down the road.

However if you want to know to do it as a regexp:

start with the letters a-z.

^[a-z]

At least 5 legal characters following that  (use a lookahead assertion
to check):

(?=[!#%&$£\w]{5})

Zero or more non-punctuation characters, followed by a a punctuation
character, followed zero or more of any valid character.

\w*[!#%&$£][!#%&$£\w]*

And then anchor the end of the string with a $.

Put all that together with a bit of case insensitivity and you get.

$regexp = '/^[a-z](?=[!#%&$£\w]{5})\w*[!#%&$£][!#%&$£\w]*$/i';

$status = preg_match($regexp, $password) ? 'PASS' : 'FAIL';

Named pipes are blocking - if you open one for reading and there's
nothing writing then the reading process will be blocked. And as
you've just seen, the same happens if you open one for writing and
there's nothing reading it.

You can change that behaviour by specifying the O_NONBLOCK flag when
opening the pipe - if you're opening it for writing, the attempt will
fail immediately rather than waiting for something to read.

I don't know of a way to do that through fopen(), but you can probably
manage it using dio_open() if you *really* want to.

It might be better to rethink how your processes communicate?

There's no problem with variable names as parameters to copy() - you
can test that in a few seconds.

   $ touch foo
   $ php -a
   Interactive mode enabled

   

   $ ls
   foo   foo.bak

So the problem is elsewhere.

99 times in 100 you've either messed up the filenames or you've not
got appropriate file permissions to do the copy.

Salve,

(a) It won't make a blind bit of difference to MySQL whether you have

WTF do you need so many WTFs?

Adding a set of parenthesis isn't causing the error. Adding an
open-bracket and then an escaped close-bracket is causing your error.
The "missing ) at offset 12" is a bit of a clue there.

Backslashes are special characters to both single-quoted strings AND
regular expressions so if you use them, you're normally going to have
to escape them twice.

So if you want optional double backslashes, followed by any characters
followed by a backslash followed by any characters - which is what I'm
guessing you were aiming at, you'd start off with this:

/^(\\)?.+\.+$/

you need to escape the backslashes for the regular expression engine
so you get this:

/^()?.+\\.+$/

and you're supplying it in a single-quoted string, which also needs
the backslashes escaped, so you get this:

'/^()?.+.+$/'

by which point you should be swearing at Microsoft for choosing such a
stupid character for a login string delimiter.

Clear?

The pad function simply returns the text padded to the blocksize.

The unpad function returns the unpadded text, or false if the padding
isn't valid.

function pkcs5_pad ($text, $blocksize)

  $pad = $blocksize - (strlen($text) % $blocksize);

Granted, deprecated might be putting it a little strong. They are

I did quote the note concerning them in its entirety. If I had simply

Similarly, what I quoted was the entire text of the php.ini comment.

Firstly, I didn't actually suggest they were disabled. I suggested
that they should be off by default. If they're needed then it's simple
to turn them on, but it would discourage new developers from using a
construct which is not compatible with xml and xhtml.

Now I can't argue that it's not valid sgml as I'm not overly familiar
with the sgml standard (in fact I don't recall mentioning sgml at
all), but it's certainly not valid xml or xhtml.

If you've seen this note, then why did you need to ask?

It doesn't really matter whether you've seen a server where short tags
are disabled, just the possibility that they won't work means they're
not portable. Long tags always work.

Many experienced sysadmins automatically disable everything that's not
needed, and short tags definitely come under that heading.

Back-compatibility.

Short tags were around before the long form and millions of scripts
were already using them by the time the xml/xhtml issue became
apparent.

Security really doesn't have anything to do with this.

Short tags have been deprecated for years. Both the manual and the
php.ini file itself advise people not to use them. Personally I think
it's about time they were turned off by default, but that's bound to
annoy a lot of people who've ignored the warnings.

You've not indicated which is line 21, but I presume it's the bit

Looking at your binary data in a hex editor, you've got what looks

length of the compressed data, then you've got probably got 990 bytes
following that that you should be decompressing.

You could use the pspell extension; add your manufacturers to your

pspell_suggest() to suggest alternatives.

I'm afraid not. You can hack recursion in Perl with the (??{ }) 
postponed expression construct. But PCRE doesn't support it.

Without recursion, the best you can do is decide on a reasonable depth
of nested comments and hardcode that.

I'm not sure exactly what you mean here. It's true that comments don't
affect how mail gets delivered, but they're very definitely part of
the address and may well have a meaning to the recipient that you
can't predict. They could be using it for anti-spam or to disinguish
between users of a mailbox or... well, anything really.

Which is the reason that RFC-2821 recommends that they be passed to
the recipient unchanged.

I had a quick look through my email last night and found 14 different
email validation regular expressions posted to this list in the last
few months. All of them would falsely reject valid addresses even
without taking comments into account. 6 of them wouldn't even allow
"judy.o'[EMAIL PROTECTED]" and another 3 would reject mail from the
entire .museum TLD.

What that would indicate to me, is that many people can't even
recognise what a "good enough" regular expression looks like.

Possibly because those whose email addresses it rejected couldn't
contact you to complain? :-)

Actually, I have very little problem with your regexp - I'd like it to
handle domain literals, as they can be useful in communicating with
people with broken DNS. But that's about it.

1.  Technically you can't write a regular expression that matches
*all* valid email addresses as part of the address specification is
recursive.

 ccontent   = ctext / quoted-pair / comment
 comment  = "(" *([FWS] ccontent) [FWS] ")"

Admittedly 99.99% of people don't even know you *can* comment email
addresses so it's not a huge problem...

2. Very few people seem to be capable of recognising a *good* regular
expression, let alone writing one. It seems clear that validating an
address is a task that many people want to do, but few can do
properly. I'd say that's a good reason for making it a built-in
function.

I'm sorry, but this regular expression rejects many perfectly valid
ASCII characters. It seems to take into account only dot-atoms, not
quoted-strings. It also rejects valid addresses using domain-literals.

If this really fails, it means that $cmd doesn't decrypt into

Are you trying to generate the query from the array?

If so, you are better off using the SQL 'IN' construct.

SELECT * FROM client WHERE clientaccountmanager IN (value1, value2,  value3,...)

Then all you need to do is generate a comma separated list of values
from the array, which you can easily do with join().

$values = join(', ', $array);

Then insert it in your query:

$query = "SELECT * FROM client WHERE clientaccountmanager IN ($values)"

Re: [PHP] Two MySQL connections in one script not working as expected

[Robin Vickery]

If you make two calls to mysql_connect with the same parameters, the
second will not make a new connection - it will return the existing
connection. The manual explains this:

http://www.php.net/mysql_connect

"If a second call is made to mysql_connect()  with the same arguments,
no new link will be established, but instead, the link identifier of
the already opened link will be returned. The new_link parameter
modifies this behavior and makes mysql_connect() always open a new
link, even if mysql_connect() was called before with the same
parameters."

$sonuc3 is a mysql result resource NOT a mysql connection. You can't close it.

If you want to close the connection that you just opened then call

This only allows
