Re: [PHP] regular expression for integer range

Hi all,
I want to write regular expression for checking the string format
entered
by user.
the allowed formats are
examples:
10
10,
10,12-10
12-10
that is the valid strings are:
1. only integer
2. an integer, range of integers example 3
and no other characters must be allowed.
You could simplify the matter by replacing all - and , with, say, 0 and
then using the simple \d+ (I think) regexp.
Hi babu,
As you've pointed out, you have 4 distinct scenarios to deal with, and it
may be very difficult, without a great deal of tuning and tweaking, to
define a regular expression that can effectively match all 4 scenarios
without including false matches as well.
One way of dealing with this is to build more specialized and exact
regular
expressions for each possible scenario and group them together in an if
statement.
Eg.
if (preg_match('/^\d+$/',$subject) || preg_match('/^\d+,$/',$subject) ||
preg_match('/^\d+,\d+-\d+$/', $subject) || etc etc){
// code for successful match of valid data in $subject
} else {
// code for invalid data in $subject
}
Basically, the if/else statement is testing each distinct possible pattern
and executing code if any of those distinct possible patterns match.
It may not ultimately be the most graceful way of dealing with the
situation, but having spent many hours attempting to tweak complex regular
expressions looking for the magic combination, I've learned that breaking
scenarios down this way can save a lot of development time and
frustration.
This doesn't mean there isn't a benefit to finding the perfect regular
expression for your needs, just that it can often be difficult to
guarantee
your code won't be plagued by false matches or false exclusions as your
expression becomes more and more complex.
Hope this helps a little.
Much warmth,
Murray

For starters, those \ characters are probably not doing what you think...
\ is special in PHP inside quotes (and apostrophes)
\ is also special to preg_match.
While \d might be fine today, because \d isn't a special combination to
PHP, you'd be safer to write \\d so that PHP will ALWAYS send \d to the
preg engine.

{
echo not valid phonebr /;

if(ereg(^[+]?[0-9\-[:space:]\)\(]+$, $test_phone))
Here, the \- is out of whack.
If you want a literal - to be valid, put it at the end of your character
class [0-9-] for example, allows 0-9 and the '-'
[a-zA-Z0-9-] allows alphanumeric and the '-'
I don't think \- is kosher, though, which is your REG_ERANGE error.

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-

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.

That expression looks perfectly valid for the conditions you have stated
(given that you meant 12 digits, not 11, which would be correct for UK
mobiles). There must be some other kind of error.
As a first step, I suggest you do a var_dump($_POST['mobile_number']) to
make sure it's exactly what you think it should be. (And, yes, you should
be quoting the index to the $_POST[] array.)
if(!preg_match( $regexp, $_POST[mobile_number] )){
$error = Invalid Mobile Number;
/snip
The number nust be 11 numbers long, be all numbers, have no
spaces and begin
with 447.
However, if you mean genuine mobiles, and not pagers or other follow-me type
numbers in the UK 07 range (or even completely unallocated parts of it!),
then you need to refine that pattern a bit; this should do:
$regexp = /^447[7-9][0-9]{8}$/;

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 :)

Re: [PHP] regular expression
First of all, you might want to put more than one % probably like %%% Reason is, asp users % % like php uses ? ?. Just a precaution. You almost had the regex right. /%[a-z]+%/i Thans means, starts with a %, can match a-z, at least once (the + part) but as many times (greedy), then another %, and the i means case-insensitive. If you don't have that you'd have to do [a-zA-Z] instead.

Robin Vickery sagde:
The S modifier that you're using means that it's storing the studied
expression. If the regexp changes each time around the loop then over
3 iterations, that'll add up. See if removing that modifier helps
at all.
The S modifier wasn't needed, I added it because I thought it would speed it up but
it didn't. Removing it didn't help on the memory usage, but it performs a little
better without.
If that's not it, then these *might* save you some memory, although
I've not tested them:
I'm not entirely sure why you're matching (.*) at the end then putting
it back in with your replacement text. Without running it, I'd have
thought that you could leave out the (.*) from your pattern and the $4
from your replacement and get exactly the same effect.
I tried removing $4 and (.*) but the result isn't the same, actually my first reg.
exp. didn't have $4, but I had to add it. Without it 51 of the 1246 texts isn't
processed right? Also there isn't really any difference in how it performs with or
without it.
You could use a non-capturing subpattern for $2 which you're not using
in your replacement.
$replace = /^((?:[a-z]+?[^a-z]+?){.($count).})(.$typedmask.)/i;
I didn't know you could do that.. cool :), this made the script run a little faster
but it still uses the same amount of memory.
And maybe a look-behind assertion for the first subpattern rather than
a capturing pattern then re-inserting $1.
$replace = /^(?=(?:[a-z]+?[^a-z]+?){.($count).})(.$typedmask.)/i;
$with = error-start sourcetext=.$corr['sourcetext']. id=.$corr['id'].
...
With ?= I get a lot of warnings:
here is an example:
$replace is '/^(?=(?:[a-z]+?[^a-z]+?){50})(go)(.*)/i'
$with is 'error-start sourcetext=3 id=49 group=- class=- corrected-from=go
corrected-to=god$2error-end sourcetext=3 id=49$3'
br /
bWarning/b: Compilation failed: lookbehind assertion is not fixed length at
offset 34
with the corrections added the reg.exp. looks like this:
$typedmask = preg_replace(/\s+/,.*?,$corr['typed']);
$replace = '/^((?:[a-z]+?[^a-z]+?){'.($count).'})('.$typedmask.')(.*)/i';
$with = '$1error-start sourcetext='.$corr['sourcetext'].' id='.$corr['id'].'
group='.$corr['grupper'].' class='.$corr['ordklasse'].'
corrected-from='.$corr['typed'].'
corrected-to='.$corr['corrected'].'$2error-end
sourcetext='.$corr['sourcetext'].' id='.$corr['id'].'$3';
$text = $skipText[0] . preg_replace ($replace,$with,$text,1);
It completes a little faster and the output is exactly the same as before,
but it still uses way too much memory.

Re: [PHP] Regular Expression - it works but uses way too much memory ?
Sorry to post this again but it's a little urgent.
The preg_replace in my script allocates a little memory every time it is called and
doesn't free it again untill the script ends.
I don't know if it is normal behaviour for preg_replace or if it is my reg. exp.
that causes this.
The problem is that I call preg_replace a little more than 3 times and that
causes quite a lot of memory to be allocated.
Doesn't anybody know if this is a problem in preg_replace or is there a better
maillist/forum for this kind of questions?
Any answer will be appreciated :)

Above preg_replace works as expected, I have it inside a loop that processes 1000
texts and replaces a total of 3 words.
The problem is that it accumulates memory up to 200MB, that isn't freed again until
the script completes?
It runs for about 1 - 2 minutes and allocates more and more memory.
If I comment out the preg_replace the memory usage looks normal, so I'm pretty sure
that is where the problem is?
My question is basically, is it something in my reg. exp. that it totally nuts or is
it normal behaviour for preg_replace to allocate memory and not free it again until
the script ends?

I'm not entirely sure why you're matching (.*) at the end then putting
it back in with your replacement text. Without running it, I'd have
thought that you could leave out the (.*) from your pattern and the $4
from your replacement and get exactly the same effect.
$replace = /^(([a-z]+?[^a-z]+?){.($count).})(.$typedmask.)/i;
...
sourcetext=.$corr['sourcetext']. id=.$corr['id'].;
You could use a non-capturing subpattern for $2 which you're not using
in your replacement.
$replace = /^((?:[a-z]+?[^a-z]+?){.($count).})(.$typedmask.)/i;
And maybe a look-behind assertion for the first subpattern rather than
a capturing pattern then re-inserting $1.
$replace = /^(?=(?:[a-z]+?[^a-z]+?){.($count).})(.$typedmask.)/i;
$with = error-start sourcetext=.$corr['sourcetext']. id=.$corr['id'].

your regex is matching one or more whitespace characters between [ and

There's an input string like {str1,str2,...,strN}. I want to capture
all these strings and due to complexity of them I use a preg_match_all()
instead of simple split. A pattern for the matching strings is ready but
I cannot imagine how to specify that strings are separated by commas
and the last one is not followed by comma. For example, I'm afraid that
this pattern /^{(?:(pattern),)*|(pattern)?}$/ can match and capture
properly constructed input string, but, in addition, this matches if
the string end is ,}. Any ideas?

Re: [PHP] Regular Expression for a UK mobile phone number
I am trying to create a regular expression for a mobile phone number. The
number must be 12 digits long(0-9) and begin with 447 and have no spaces.
So far I have come up with this but it keeps telling me the number is
invalid even when its correct!
Try this:
$regexp = /447[0-9]{9}/;
if($_POST[mobile_number] != ''){
if(!preg_match( $regexp, $_POST[mobile_number] )){
$error = Invalid Mobile Number;
header(Location:edit_rep.php?error=$errorrep_id=.$_GET[rep_id].client_id=.$_GET[client_id].rep_name=.$_GET[rep_name].client_name=.$_GET[client_name].);
exit;
}
}
Also, your regexp is a little permissive; you can anchor it like so:
$regexp = /^447[0-9]{9}$/;

Re: [PHP] Regular Expression for a UK mobile phone number
but the regular expression still seems to reject the number... Can you provide an example of numbers it rejects? My answer was based on the simple fact that you were testing for numbers that matched, and returning a rejection based on that. The regexp is simple enough -- some examples of input where it fails would be good, perhaps in a reduced case, like: foreach($array_of_inputs_to_check as $input) printf(input: %s, matches?: %d\n, $input, check($input); - michal migurski- contact info and pgp key: sf/cahttp://mike.teczno.com/contact.html -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Re: [PHP] regular expression
Alright,
first of all, in E-Mail Headers every param needs to be written in a
seperate line, therefore following will work even with multiple recipients:
$recipients = array();
$header = explode( \n , $header );
foreach ( $header AS $param ) {
$param = trim ( $param );
if ( strtolower( substr( $param , 0 , 3 ) ) == 'to:' ) {
$recipients[] = trim ( substr( $param , 3 ) );
}
}
This will match every of these:
'TO:[EMAIL PROTECTED]'
' TO: [EMAIL PROTECTED]'
' TO:Mr Baz [EMAIL PROTECTED]'
' TO:[EMAIL PROTECTED],[EMAIL PROTECTED],[EMAIL PROTECTED]'
etc. pp

PS: I'm not sure about wether 'TO :' is allowed or not - sad thing :-)

Re: [PHP] regular expression
* Thus wrote Robert Kornfeld ([EMAIL PROTECTED]):
hey, professionals out there:
i need to write a parser for an email-header to retrieve the email of the
'To:'-field.
there are 2 possibilities:
'To: [EMAIL PROTECTED]' or
'To: first foo [EMAIL PROTECTED]'
Actually the second one needs to be
first foo [EMAIL PROTECTED] - or -
foo [EMAIL PROTECTED]
so you need something like:
/([^]*([^]+)|(.*))/
That will parse one address. if you have more than one address
you'll have to break the address list apart sperated by ';'
ie. To: [EMAIL PROTECTED]; foo bar [EMAIL PROTECTED]
$emails = explode(';', $email_list);
and to get that email address list you'll have to take into account
folding ie.
To: address;
address2@
domain.com
So to allow for this while reading the header lines:
$last_field = '';
foreach($headerline) {
// detect a folded header line
if ($headerline{1} == ' ' || $headerline{1} == \t ) {
$headers[$last_field] .= trim($headerline);
continue;
}
// check for end of headers
if ($headerline{1} == \n) {
break;// we're done with headers.
}
//now split the field
list($field, $data) = explode(':', $headerline, 2);
// ensure name is consistent ok
$field = strtolower($field);
// save the data
$headers[$field] = $data;
// incase its folded
$last_field = $field;
}
Now apply the other two methods to $headers['to'];
that was a little more than a regex, but I hope it helps.

It's not so easy to match an entire IMG tag, because first of all the

I would do :
ereg(img ([^]+), $your_text, $img_array);

My approach would be somewhat something good from both worlds it IS
possible to match an entire image tag with preg_match_all:
/img (\s*(alt|src|style|title|name)=\s*([^]*)\s*)*\/?/i
Of course, this is not tested .. but should come at least a bit close to
what you want ...

What I
really want to get out of this regex is
1) image name
2) image alt text
3) image title text
, so only those three parentheses are of capturing
kind and the rest is marked as non-capturing...
I wonder will this work (if I change this part):
(?:
(?:title\s*=\s*(?:|\')) # title
(?\b\S*\b)
(?:|\')*\s*
|
(?:alt\s*=\s*(?:|\'))# alt
(?\b\S*\b)
(?:|\')*\s*
)
, notice the or character. I guess it should
match, as the order is not important now...
I love monster regexes ;8].

So I'll get something like
$images = array(
[0] = array(
src = 'image1.jpg',
alt = '',
title = 'a cow'
),
[1] ...
)
...nice :8]. Thank you!

function passgen()

Looks good to me. You're too kind; I was going to leave the exercise to
the student to complete :-)
How about,
$password = strtolower(substr(md5(uniqid(time())), 0, 7));
Will get you a unique password consisting of 8
rather random lowercase alphanumerics.

RE: [PHP] Regular expression help
This condition is true if there is no space, new line or tabulator in $val

Re: [PHP] Regular expression help
Thanks Bronislav for your answer but this can't be it as the following test
code passes validation:
?Php
$val = \t test \n;
if(ereg([^ \t\n],$val)) {
echo 'In here!!';
}
echo 'BR' . nl2br($val);
?
Anyone has an idea?

Re: [PHP] Regular expression help
Hi,
^ inside [] means not the following chars, so your expression means:
if ($val contains no space , no tab \t and no newline \n) {
//do the job ...
}

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.

Re: [PHP] Regular expression help
That's it!
Thank you very much, you have the answer.
I wonder why the programmer did not write the following line instead:
if (strlen(trim($val))) {
// Do the job here
}
Anyways, you just proved that I did not fix the bug! Now I have to work even
more! :-P
Thanks

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.

You are using a + as the modifier on the space between p.o. and box. +
means 1 or more. Option 3 does not have a space. Try using * which is 0 or
more, or ? which is 0 or 1.

/p\.?o\.?\s*box/i
p followed by optional period (\.?)
o followed by optional period
zero or more whitespace (\s*)
box
mine has the added advantage of matching po.box and po. box

hmm.. if i read that right that will only match #2 (I'm not sure
that the [] includes a null match or not.) Also the character class
[] has special escapes, you dont need to escape the period because
the period is literal there.
there are other alternatives people might also type like:
p/o box
thus my original pattern becomes:
/p[.\\]?o\.?\s*box/i

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!
Mike
