Not entirely sure what you're after (try posting some before and after

Is it possible for you to use a mixture of html_entity_decode, htmlentities
e.g.

Hello, Can someone here give me a glue how to do the following. I guess I need to use regular expressions here. I have absolutely zero experience with regular expressions. (if there's another way to do this I don't mind. I jus need to get this done somehow :) I need to strip all characters from the following text string exept the image path... img width=\99\ height=\120\ border=\0\ src=\../../images/new/thumps/4123141112007590373240.jpg\ /...and then store the path to DB. Image path lengh can vary so I guess that I need to extract all characters after scr=\until next\or somethig similar.

It's a unit test showing how you can use SimpleXML to do what you want.
It's written for Testilence out of sheer laziness, but any unit testing
tool would do (after cosmetic changes to the code).
The test case contains two pretty obvious tests, just read the
function names, their bodies should be pretty obvious. On thing that
might be a little non-obvious is the strval(): that was the only way I
found to get the string out of the very uncommunicative
SimpleXMLElement.
I forgot to mention that this part:
img width=99 height=120 border=0 src=%s /',
is not always the same. The image properties can vary.
That's one of the reasons I didn't go the regexp route.
Don't treat XML as text, it's not.

Your subject says regular expression help but your problem is with the
global variable $mac So which is it? If you're going to declare a
variable as 'global' then it has to be done in every function in which that
variable is to be used.
Which means here:
function chk_mac( $mac ) {
if( eregi(
^[0-9A-Fa-f]{2}\:[0-9A-Fa-f]{2}\:[0-9A-Fa-f]{2}\:[0-9A-Fa-f]{2}\:[0-9A-Fa-
f]{2}\:[0-9A-Fa-f]{2}$, $mac ) ) {
return 0;
} else {
return 1;
}
}
and wherever else.

if you want to use globals you need to use the global in the function
not the main body.
afaict you don't need globals at all you pass mac1 to each function and
use it as $mac in the function (exactly what you want to do) and return
local $mac to $mac in the main body. perfectly legal. If you set mac
to global in the function I suspect that you end up not using the local
mac and are testing an empty var in the first pass of fix_mac.
remove the global statements and you are well on your way.

Re: [PHP] regular expression help
Howdy,
Regular expressions are a simple way of matching patters.
You can learn more about regular expressions in general here:
http://www.opengroup.org/onlinepubs/007908799/xbd/re.html
If you are interested in using regular expressions in PHP, check out
these sites:
http://www.php.net/manual/en/reference.pcre.pattern.syntax.php
http://www.php.net/manual/en/reference.pcre.pattern.modifiers.php
A regex to match what you are looking for would be /\{(.+?)\}/, and then
just replace it without the { and } for the replace part.

It works great, thank you. I had tried something on my own previously,
but without the ungreedy modifier and with replacements inside a
repeated while{} cycle instead of a callback. The main drawback in my
version was that an X near hopefully would have been replaced as
well (since technically it is between b and /b). But that wasn't
what I wanted, of course.

Try this snippet
pre
?php
$css = fopen(http://www.csszengarden.com//001/001.css;, r);
$data = fread($css, 3);
preg_match_all(/#.+({ )/, $data, $out);
print_r($out);
?
/pre
It gets the default css from the zengarden site. (30k is a large
buffer, but this is not a howto on buffered reads)
The regular expression
/#.+({ )/
means, piece by piece
# the # character
. dot is a special character in regular expressions. it can match
any character
+ is also a special character, it means match 1 or more times
so .+ means match any character 1 or more times
( ) are special characters, they match any single character inside them.
in the case of ({ ) , it matches either a space or a left bracket
So, the whole expression means:
match a strings where they start with #, followed by 1 or more
characters, followed by a space or a left-bracket
Note that these are very simplified explanations for regular expressions.
Now, try the expression
/#(.+)({ )/
and instead of print_r($out), try
print_r($out[1]);
Now you get the classnames :) Check out the following sites for more
info (they appear first when you google regular expressions).
http://sitescooper.org/tao_regexps.html
http://etext.lib.virginia.edu/helpsheets/regex.html
Also, check out the PHP manual for the preg_* functions
---
Note that the script i gave you has problems with classnames on one line, like
#footer a:link, #footer a:visited
But I won't spoon feed you :)

[PHP] Regular Expression Help
Hi folks. I'm having a little bit of a stupid moment with a regular
expression which I'm hoping someone can lend a hand with.
The regular expression I have right now matches strings between 2 and
1000 characters in length that start with one of the following
characters:
a-z
A-Z
0-9
(
)
and where the rest of the string may be made up of the following
characters:
a-z
A-Z
0-9
(
)

'
Here's the working regular expresssion:
/^[a-zA-Z0-9\(\)]{1}[ a-zA-Z0-9\(\)_\,\.\-\'\]{1,999}$/
Now, I'm trying to add \ to the valid characters but when I add a slash
after \ I get the following error:
Warning: Compilation failed: missing terminating ] for character class
at offset 54 in
/u0/vservers/*/html/classes/forms/forms_validation_functions.class.p
hp on line 184
So I escape the \ with another \, and I still get the error.
Three or four \ results in the \ character being stripped from the
string that is being tested with the regular expression.
Five \ results in the orignal error which I get with just one \.
Can anyone give any advice as to why this is happening?
Cheers and TIA.

for starters, that doesn't give me a warning at all.
also, all those escapes arn't needed:
$reg = '/^[a-zA-Z0-9()]{1}[ a-zA-Z0-9()_,.\'-]{1,999}$/';
The ' is only escaped for php, not the expression. And moving the -

That's a long expression, try:

This pattern finds 6 matches of a number or letter (the /i means

No, but I can write a quick one for you. Can't guarantee the uniqueness
of the password being generated.
function passgen()
{
srand((float) microtime() * 1000);
//Source arrays
$letters = range('a','z');
$digits = range(1,9);
//Get random items from arrays
$char = array_rand($letters, 4);
$num = array_rand($digits, 4);
//Combine the two random items into one array
for ($i = 0; $i 4; ++$i)
{
$ran_char[] = $letters[$char[$i]];
$ran_num[] = $digits[$num[$i]];
}
//build our password
$password = array_unique(array_merge($ran_char, $ran_num));
//randomize it
shuffle($password);
return join(,$password);
}

How about,
$password = strtolower(substr(md5(uniqid(time())), 0, 7));
Will get you a unique password consisting of 8
rather random lowercase alphanumerics.

Actually, the regular expression will match anything that is NOT a space,
tab, or newline. That's what the ^ character does (negates the matching).
So, if $val has anything that is NOT a space, newline, or tab in it, then
the ereg() function will return true.

That's not necessarily the correct assesment. rather:
if ($val has any character but ' ', '\t', or '\n') {
// do the job.
}
with: test\t\n
because 'test' is in there it results a a true statement.

RE: [PHP] REGULAR EXPRESSION HELP
-Original Message-
From: John [mailto:[EMAIL PROTECTED]
Sent: 12 July 2003 07:31
I need to match a pattern, not in a single-line but from a
HTML page, which
obviously has loads of lines. I need to match 2 lines from
this HTML page:
1) HTMLTITLEFirstVariable - Second Variable/TITLE/HTML
2) TABLETDTR(newline)
ThirdVariable/TR/TD/TABLE...
I tried this code:
1) preg_match(/HTMLTITLE(\S+) - (\S+)/TITLE/HTML/,
$html_page,
$variables);
2) preg_match(/TABLETDTR\n(\S+)/TR/TD/TABLE/,
$html_page,
$variables);
The first 2 variables are matched into the $variables array
but not the
third one. Sometimes when the third one is matched, it starts
from where I
want it to start but takes all the text to the end of the
HTML document!
Any ideas? Is there any characters that I should have escaped that I
didn't?? All I can think of is that because the first line
that I want to
match is on the FIRST LINE of the html page, that matches.
But reg-ex can't
handle the next line as its way down the page
Firstly, your newsline may actually be any of \n, \r, or \r\n according as
the file was built on a *nix, Mac or PC platform, so your regex should take
account of this.
Secondly, both of your examples should produce scads of errors attempting to
parse the regular expression, because you have unescaped slashes and your
delimiters are also slashes -- so either this is not a direct cut-and-paste
of what's actually in your script, or you're not letting on about something
else! The fix for this one is either to escape the slashes that are
actually part of the match, or use something other than / as your delimiter.
Thirdly, as you've got double quotes around the regex, it would be advisable
to double the backslashes themselves (to ensure PHP doesn't attempt to
interpret any of its own backslash sequences) -- either that or use single
quotes to enclose the regex.
Fourthly, and perhaps most importantly, by default the * and + modifiers are
greedy -- that is, they match as much as possible consistent with the
whole match succeeding. With your first match, this doesn't matter as
there's only one /TITLE in the document, so there's no ambiguity; with the
second match, there could be any number of occurrences of /TR/TD/TITLE
in the document, and the greedy matching of \S+ means that it will always be
the *last* of these that is found. The way to counter this is to use one of
the ungreedy modifiers in your regex.
Taking all of these into account, you probably want something like:
preg_match('!TABLETDTR(\n|\r\n|\r)(\S+)/TR/TD/TABLE!U',
$html_page, $variables);
Cheers!

RE: [PHP] Regular expression help converting doc to xml
(For the archives) The RegEx I finally used was this: search: D(.*) replace: DD\1/DD I tried this in 3 editors: jEdit, eMacs and BBEdit jEdit interpreted the replace expression as literally \1 eMacs didn't like the parenthesis in the search string In BBEdit it worked like a charm.

hi all, I have some user-supplied text on a content driven site. I am allowing A tags inside the main text, BUT I want any links to external sites (not on the chosen domain) to include a ' TARGET=_new ' element. So, A HREF=http://www.mydomain.com/mypage.php;something/a is fine A HREF=http://www.yourdomain.com/yourpage.php;something/a is wrong A HREF=http://www.yourdomain.com/yourpage.php; TARGET=_newsomething/a is fine And of course there are all the variants with and without the www, and with and without sub directories and pages. I'[d also like to make sure the dopey people have put a close tag in. I've got a few ideas on how it might be done, but I need to do it the right way, avoiding slight human errors etc. Has anyone got something written, or can point me in the right direction?

);
while ( list(,$email) = each($emails) ) {

Okay, here's what I have so far:
---snip---
if ((!$email)
|| ($email==)
|| (!eregi(^[_\.0-9a-z-]+@domain.+[a-z],$email))
)
$stop = center._ERRORINVEMAIL./centerbr;

This works, but how can I add a second domain?
ie:
---snip---
if ((!$email)
|| ($email==)
|| (!eregi(^[_\.0-9a-z-]+@domain.+[a-z],$email))
|| (!eregi(^[_\.0-9a-z-]+@otherdomain.+[a-z],$email))
)
$stop = center._ERRORINVEMAIL./centerbr;
---snip---
This doesn't work. (it returns the error no matter what I enter)
Thanks guys (and gals?)

Hi everyone,
I have a new user function that checks e-mail addresses.
I wish to only allow people from two different domains to register.
How can I filter out all other e-mail addresses and return an error if
it's
not from those domains.
Here's what I have:
if ((!$email) || ($email==) ||
(!eregi(^[_\.0-9a-z-]+@([0-9a-z][0-9a-z-]+\.)+[a-z]{2,3}$,$email)))
$stop
= center._ERRORINVEMAIL./centerbr;
What this currently does is just makes sure it's a valid e-mail address.
What I'd like it to do is if the user enters anything except @domain1.com
or
@domain2.com it spits out the error (ERRORINVEMAIL)
So (I think) It would look something like this:
if ((!$email) || ($email==) || (!eregi(^[_\.0-9a-z-]+@([DdOoMmAaIiNn1]
||
(or statement???) [DdOoMmAaIiNn2-]+\.)+[a-z]{2,3}$,$email))) $stop =
center._ERRORINVEMAIL./centerbr;
Of course, this doesn't work, but you get the point.
Thanks!
P.S.
Thanks for the Awesome List!

[PHP] Regular Expression Help
I'm trying to figure out how to say with a Regular Expression how to check
for the following characters in a phone number:
( ) -
with a length between 1 and 20 --
I've tried the following and it doesn't seem to work.
eregi(^([0-9]|\\(|\\)|\\-){1,20}$)
I'm not interested in checking for a completely valid phone number... but
instead checking to see if the phone number is numbers with or without the
( ) - characters. Plus, I think creating a Regex expr that can check for US
and International formats would be too complex.
Thanks.

oops, make that:
^[0-9\\(\\)-]{1,20}$
note: you don't have to escape the - when its the last char in the
range

ARIA 5.19 -0.0625 -1.19 5.25 4.5 48.5 100300
you can explode on a tab $arrlines = explode("\t", $the_line);
then save $arrlines[0] from every line.
Don't know if it's the most optimal way but it works :)

since the pattern has an 'or' (|), you have to look in either the second

can anyone help me figure out a regular expression to find the value of
a tag element?
for example:
tag element="my value"
tag element=value
tag element="my value" nextelement
tag element=value nextelement
tag element = "my value"
tag element = value
tag element = "my value" nextelement
tag element = value nextelement
so in each of the above i need to find either "my value" or "value"...
i tried this but it wont work for every situation:
ereg("element[ ]*[=][ ]*[\"]?([^\"]*)[ |\"|].*" ...
thanks for your help - regular expressions are not my best area!
