PHP List,
Recently I wrote a piece of code to scrape data from an HTML page.
Part of that code deleted all the unwanted text from the very top of the
page, where it says "<!DOCTYPE", all the way down to the first instance
of a "<ul>" tag.
That code looks like this:
ereg_replace("<!DOCTYPE(.*)<ul>", "", $htmlPage);
It works fine. But I noticed that on almost all the tutorial pages I
looked at, they just about always used preg_replace, and not ereg_replace.
It seemed that the main difference was that preg_replace required
forward slashes around the regular expression, like so:
preg_replace("/<!DOCTYPE(.*)<ul>/", "", $htmlPage);
But that didn't work, and returned an error.
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?
Why does the ereg work for the command above, but preg not?
! in perl regular expressions means "not" so you need to escape it:
\!
pcre expressions are very close to the same as in perl, so you can
easily move the regular expression from one language to the other
(whether that's good or not is another thing). If you have any perl
experience, they are easier to understand. If you don't, they are a
little harder to understand to start off with but are more powerful once
you work them out.
The ereg functions are simpler to use but miss a lot of functionality.
Also according to this page:
http://www.php.net/~derick/meeting-notes.html#move-ereg-to-pecl
ereg will be moved to pecl which means it will be less available (ie
most hosts won't install / enable it).

Ereg uses POSIX regular expressions which only work on textual data and
include locale functionalily. preg uses PCRE, which work on binary as well
as textual data and is a more sophisticated regex engine, incorporating
minimal matching, backreferences, inline options, lookahead/lookbehind
assertions, conditional expressions and so on.
They are often faster than the POSIX equivalents also.

Chris, Ligaya, Dave,
Thank you for responding. I understand the difference in principle
between ereg and preg much better now.
Chris wrote:

Still, when including that escape character, the following preg
expression does not find any matching text:
preg_replace("/<\!DOCTYPE(.*)<ul>/", "", $htmlPage);
Whereas this ereg expression does find a match:
ereg_replace("<!DOCTYPE(.*)<ul>", "", $htmlPage);
What do I need to do to make the preg expression succeed just as the
ereg expression does?
Thank you for your time and advice.

AFAIR, that's only true in the (?! assertion sequence.

By default, . in preg_* patterns does not match newlines. If you are matching
in a multiline string, use the s modifier to change this:
preg_replace("/<!DOCTYPE(.*)<ul>/s", "", $htmlPage);
You also don't need the parentheses -- these will capture the entire matched
expression for use in backreferences, but as you don't have any it's then
immediately thrown away. So just use:
preg_replace("/<!DOCTYPE.*<ul>/s", "", $htmlPage);
Cheers!

Jochem,
Thank you for responding.
does this one work?:
preg_replace('#^<\!DOCTYPE(.*)<ul[^>]*>#is', '', $htmlPage);
Yes, that works. I don't think I would have every figured that out on my
own - it's certainly much more complicated than the ereg equivalent.
If I may push for just one more example of how to properly use regular
expressions with preg:
It occurs to me that I've been assuming that with regular expressions I
could only remove or change specified text.
What if I wanted to get rid of everything *other* than the specified text?
Can I form an expression that would take $htmlPage and delete everything
*except* text that is between a <li> tag and a <br> tag?
Or is that something that requires much more than a single use of
preg_replace?

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 </ul> rather than <ul> 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 "<!DOCTYPE", all the way down to the first instance
of a "<ul>" 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 "<ul>" tag.
To make it match for the shortest length possible, put a question-mark
after the ".*" like so:
preg_replace("/<!DOCTYPE(.*?)<ul>/", "", $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.

That's where capturing expressions and backreferences come in handy:
preg_replace ("/.*<li>(.*)<br>.*/", "$1", $htmlPage);
(add qualifiers and other options to taste, as before!)

1. the '^' at the start of the regexp states 'must match start of the string
(or line in multiline mode)'
2. the 'i' after the the closing regexp delimiter states 'match
case-insensitively'
3. the 's' after the the closing regexp delimiter states 'the dot also matches
newlines'
4. the '<u[^>]*>' matches a UL tag with any number of attributes ... the
'[^>]*' matches a number
of characters that are not a '>' character - the square brackets denote a
character class (in
this cass with just one character in it) and the '^' at the start of the
character class
definition negates the class (i.e. turns the character class definition to mean
every character
*not* defined in the class)
PCRE is alot more powerful [imho], the downside it it has more modifiers
and syntax to control the meaning of the patterns...
read and become familiar with these 2 pages:
http://php.net/manual/en/reference.pcre.pattern.modifiers.php
http://php.net/manual/en/reference.pcre.pattern.syntax.php
and remember that writing patterns is often quite a complex - when you build one
just take i one 'assertion' at a time, ie. build the pattern up step by step...
if you give it a good go and get stuck, then there is always the list.

essentially regexps are pattern syntax for asserting where something matches
a pattern (or not) - there are various functions that allow you to act upon the
results of the pattern matching depending on your needs (see below)

yes but you wouldn't use preg_replace() but rather preg_match() or
preg_match_all()
which gives you back an array (via 3rd/4th[?] reference argument) which contains
the texts that matched (and therefore want to keep).

ah yes, good point - you can do it with preg_replace() (I only mentioned
preg_match() (et al) - guess I left my regexp hat at home today. :-)

Jochem,
Thank you for responding, and for explaining more about regular expressions.
yes but you wouldn't use preg_replace() but rather preg_match() or
preg_match_all()
which gives you back an array (via 3rd/4th[?] reference argument) which contains
the texts that matched (and therefore want to keep).
I looked up preg_match_all() on php.net, and, in combination with what
was said before, came up with this syntax:
preg_match_all( "#^<li[^>]*>(.*)<br[^>]*>#is", $response, $wordList,
PREG_PATTERN_ORDER );
var_dump($wordList);
The idea is to catch all text between <li> and <br> tags.
Unfortunately, the result I get from var_dump is:
array(2) { [0]=> array(0) { } [1]=> array(0) { } }
In other words, it made no matches.
The text being searched is an entire web page which contains the following:
(Please note the following includes utf-8 encoded Japanese text.
Apologies if it comes out as ASCII gibberish)
<FONT color="red">日本語</FONT>は<FONT color="red">簡単</FONT>だよ<br>
<ul><li> 日本語 【にほんご】 (n) Japanese language; (P); EP <br>
<li> 簡単 【かんたん】 (adj-na,n) simple; (P); EP <br>
</ul><p>
So, my preg_match_all search should have found:
日本語 【にほんご】 (n) Japanese language; (P); EP
簡単 【かんたん】 (adj-na,n) simple; (P); EP
I've checked and rechecked my syntax, and I can't see why it would fail.
Have I messed up the regular expression, or the use of preg_match_all?

^--- remove the caret as you dont want to only match when
the line
starts with <li> (the <li> can be anywhere on the line)
I'll assume you also have the mb extension setup.

Everybody missed one important difference. The PCRE module is compiled
into PHP by default. The POSIX module is not included by default.
Therefore it's not safe to use the POSIX regular expression module if
you intend to deploy your code on another system.

Hello.
Since my ISP does not provide the tidy module for Apache, I tested
writing a wrapper script for a locally installed tidy binary. In
general, the script is triggered by a modification to the .htaccess
file like so:
AddHandler server-parsed .php
Action server-parsed /tidy_wrapper.php5
All php pages are by that means "treated" by the script
tidy_wrapper.php5.
Here is the code for tidy_wrapper.php5:
<?php
chdir ( dirname ( $_SERVER['PATH_TRANSLATED'] ) );
ob_start();
include ( $_SERVER['PATH_TRANSLATED'] );
$output = ob_get_contents();
ob_end_clean();
// Including a line with the commend "<!-- NO TIDY !-->" will turn
off tidy conversion
if ( !stristr ( $output, "<!-- NO TIDY !-->" ) ) {
$localfile = tempnam ( '../tmp', "tmp" );
$handle = fopen($localfile, "w");
fwrite($handle, $output);
fclose($handle);
$command = '/Library/WebServer/CGI-Executables/tidy -iq --show-
errors 0 --show-warnings 0 -wrap 100 ' . $localfile . ' 2>&1';
exec ( $command, $output_exec );
echo implode ( "\n", $output_exec );
unlink ( $localfile );
} else {
echo $output;
}
exit;
?>
Although the script is actually working fine, there is at least one
downside: speed. As you can see, the output buffer must be written to
a file in order to be processed by tidy. I was not able to get tidy
to accept a string for processing. Doing so, tidy throws en error. I
have looked through tidy documentation without finding any clues. I
would appreciate any hints. Any ideas for a walk-around for that file
saving-thing would be welcome!
Otherwise, I strongly feel that this script might become/be a
security hole. Because it does not validate the included PHP code, it
could be misused for doing bad stuff, or am I wrong? Once more, any
suggestions are welcome.
regards,

Good news/kinda' bad news (but not really); I am proud to say that I

This creates an immediate opening for a creative applications developer
with PHP, MySQL, Oracle, the usual web skills/experience in the San

I want to have a regular expression that check the following criteria are

- has at least 1 number

I'm happy to work out the structure of a postcode etc, but to be honest I'm
still fairly new to working with regular expressions.
What the best/easiest way to check whether a variable contains a range? It

It can be done; but, it's simpler to simply to make an if() with
(strlen($password) > 5) && (strlen($password) < max) && pre_match("%[a-z]+%i"%, $password)
&& preg_match("%\d+%", $password)

Some mistakes there:
1) You want to assign strlen to a variable before the if, since you're
calling it twice in the if. I'm not certain how fast strlen is, but it's
usually a bad idea to repeat useless function calls like that.
2) Isn't your second function call supposed to be preg_match, and not
pre_match?

Not terribly difficult at all. One SMTP library for PHP and you're away.

In most cases, your PHP build is set up with mail() attached to whatever
SMTP you have on the server.
you would just use the following...
mail($recipientemail,$subject,$message);

Yes, the list serve software has the opt-in/confirmation stuff covered. I'm
just trying to get the sub/unsub form on the website going.
Thanks

what I need is what I would use after the form is submitted - responding to
whether the form sent the value (post likely from a dropdown field) of
"subscribe" or unsubscribe" to the posted page for processing.

I'm sure someone here has used / set up paypal but they provide complete
instructions on everything you need to do.
If you have any problems, that's what their support team is for.

I have a web server and an images server. My web server doesn't have
enought space for the images, hence the images server. I have to download
properties from a realty database hourly and the data goes in to a db on my
webserver while the image needs to be taken from a MSSQL db and written to
the images server as an actual .jpg or .gif file. Fopen, however, won't let
me write using the http protocol. How can I open and write files between
servers?
Thanks!

Couple of options come to mind, and I'm sure there are many others...
Option 1: nfs mount / share your partition drive(s) on your web server.
Option 2: Write the files out locally and then have a backend process
that moves them to the image server.

Write locally, scripted FTP across?
Write locally, scripted rsync across?

This scenario would be one of the times that I would use LOB's for the
image data. That way you could simply drop in another SQL server when
you start running out of space with 0 downtime.
That being said, why not try a SOAP webservice or a FTP PUT?
We use SOAP where there are no FP servers, and on the local network it
does well with 100MB+ files. I think also fopen and fput do remote
connections, but I may be wrong there.

You mean the http protocol won't let you write. At any rate, you can try
using ftp instead of http (you'll need to make sure it's set up on the
images server). Alternatively you can use a network file system or use
CURL or low level sockets to POST them to your images server.
Cheers,
Rob.

That's what I was thinking if you wanted to keep it all HTTP. You could have
an script on the images server that you submit the file to through a POST.
Then the script would move it to the appropriate place. Remember to keep
security in mind though.

Hi all,
I need to get local user IP, but server with apache and php is in
another subnetwork.
So from server environment I can get only router's IP.
The only solution that I see - is getting with some magic algorithm
local IP from brouser and sending it to server.
My application is for intranet, so I don't see any reason to make users
authorization.
Any ideas for this?
thanks beforehand

you can't always get the real users IP because of proxies, anonimizers,
firewalls/gateways
[on the user end] (and don't bother using an IP as an absolute indicator when
validating a
session - you can use it as one of a number of metrics - for instance AOL users
have their
IP addresses changed roughly every 300 milliseconds).
nonetheless here are a couple of funcs that might help you (at least to
understand
what is possible it terms of trying to determine a users IP):
/* Determine if an ip is in a net.
* E.G. 120.120.120.120 in 120.120.0.0/16
*/
function isIPInSubnet($ip, $net, $mask)
{
$firstpart = substr(str_pad(decbin(ip2long($net)), 32, "0", STR_PAD_LEFT)
,0 , $mask);
$firstip = substr(str_pad(decbin(ip2long($ip)), 32, "0", STR_PAD_LEFT),
0, $mask);
return (strcmp($firstpart, $firstip) == 0);
}
/* This function check if a ip is in an array of nets (ip and mask) */
function isPrivateIP($theip)
{
foreach (array("10.0.0.0/8",
"172.16.0.0/12",
"192.168.0.0/16") as $subnet)
{
list($net, $mask) = explode('/', $subnet);
if(isIPInSubnet($theip,$net,$mask)) {
return true;
}
}
return false;
}
/* Building the ip array with the HTTP_X_FORWARDED_FOR and REMOTE_ADDR HTTP
vars.
* With this function we get an array where first are the ip's listed in
* HTTP_X_FORWARDED_FOR and the last ip is the REMOTE_ADDR
*/
function getRequestIPs()
{
$ipList = array();
foreach (array('HTTP_X_FORWARDED_FOR', 'HTTP_FORWARDED_FOR', 'REMOTE_ADDR')
as $key) {
if (isset($_SERVER[$key]) && $_SERVER[$key]) {
$ipList = array_merge($ipList, explode(',', $_SERVER[$key]));
break;
}
}
return $ipList;
}
/* try hard to determine whAt the users/clients public IP address is */
function getRequestIP($allowPrivIPs = false)
{
foreach (getRequestIPs() as $ip) {
if($ip && ($allowPrivIPs === true || !isPrivateIP($ip))) {
return $ip;
}
}
return 'unknown';

Gawd, AOL causes us so many headaches with that crap.
