 Hi All,

 Need help in resolving the below problem-

 The above will exactly match the third value $postText = chapters 5, 6,
 7;

 By Above $matches will contain a value of : $matches[1] = '5, 6, 7';

 Now i need a SINGLE regular expression which can match first, second
 variable above or any number of comma separated string and IMPORTANTLY
 provide me that whole comma separated sting value (as above) in single array
 key element like below-

 $matches[1] = '5, 6, 7';
 OR
 $matches[1] = '5, 6';
 OR
 $matches[1] = '5, 6, 7, 8, 9';


 Also I have to use regular expression only as the flow of the code does not

 master/base string.

No problem.

If you are on Windows, then the RegexBuddy application from JGSoft is
pretty good. It allows you to build regex in a step by step way with a
full description of what the regex will do, along with testing and
code snippets. Also has a lot of examples to work from and a built in
support forum.

BTW. I'm not connected to JGSoft. Just a happy licensee.

Richard.

Not tested, but I think it should work:

preg_match_all('/(\d+),/', $postText, $matches);

even using this method you're still going to have to combine the two

ps: there may be something in the ?name syntax; I don't think so though..

You didnt get my point,.
your codes output will be
Array (2) {
[0] = charge,
[1]= 100
}

But I want this,
Array (1) {
charge = 100
}

Thats why I used ?Pname syntax, In name I used \1, means the last
matched patter would be the key.

I can do this by preg_match_all(), then array_combine() funciton.
But I was thinking if I could make it with calling only preg_match_all

it seem's everybody is giving you the same answers; here's a definitive 
look at the problem (as far as I'm aware)


all preg_* functions can only return back string's, or array's of 
strings; there is no method of returning back an associative array as 
you would like; the closest you can get is by using preg_replace or 
preg_replace_callback as follows:


print_r( preg_replace_callback('|td(.*)/tdtd(\d+)/td|', 
create_function(

'$matches',
'return array($matches[0],$matches[1]);'
), $string) );

this will fall as the internals of preg* casts the array to a string

alternative:

print_r( preg_replace('|td(.*)/tdtd(\d+)/td|e', 
'array($1,$2)', $string) );


this will also fail as the internals of preg* casts the array to a string.

similarly all other options you could go down such as simple explodes, 
strip_tags or even more complex stream filters will only allow you to 
return strings, or numerical array's of strings.


This leaves you high and dry I'm afraid - the only thing for it is to 
create a simple function to handle this for you; something like


function td_thing( $string ) {
$a = preg_replace('|td(.*)/tdtd(\d+)/td|e', '$1 $2', $string);
$b = explode(' ', $a);
return array($b[0] = $b[1]);
}

maybe just maybe you or I or somebody else can find a way to do this 
easily in one line; but for now a function similar to above is the best 
you can do..

Nathan

you can return an array which has friendly name. run the following code,

allso run this code too for backreference idea,

preg_match_all('/(\w) (\1)/',$y,$m);

[PHP] Re: Regular Expression just one step away from what I need....

[M. Sokolewicz]

Jay Blanchard wrote:

Given the string 'foo''bar''glorp' (all quotes are single quotes)I had
hoped to find a regular expression using preg_match that would return an
array containing just those words without having to go through
additional gyrations, like exploding a string to get an array. I have
only had limited luck

$theString = 'foo''bar''glorp';
preg_match( /\'(.*)\'/, $theString, $matches);
print_r($matches);

Array
(
[0] = 'foo''bar''glorp'
[1] = foo''bar''glorp
)

Of course $matches[0] has the entire string and $matches[1] contains the
returned string minus the leading and trailing single quote. I can
explode $matches[1] to get what I want, but it is an extra step and I am
sure that I have done this before but cannot locate the code in
question. I would like the results to be

Array
(
[0] = 'foo''bar''glorp'
[1] = foo
[2] = bar
[3] = glorp
)

That way I can use the $matches array without having to create another
array to hold the values. I feel as if I am really close on the regex to
do this, but cannot seem to find (after much head scratching and teeth
gnashing) the proper solution.

Much thanks!


2(-3) steps:
1. Make it _un_greedy (preg_* are greedy by default, so /'(.*)'/U will 
match foo''bar''glorp, making it ungreedy (/U modifier) would make it 
match just foo

2. Make it fetch _all_ matches, use preg_match_all
(3. there's no need to escape single quotes in this string :))

The following works:
preg_match_all(/'(.*)'/U, 'foo''bar''glorp', $matches);
print_r($matches);

[PHP] Re: regular expression help!

[Al]

First stripslashes() and all newlines [\n\r*]. It makes the regex much easier.

$pattern= %img\x20[\w\d\=\x20]+(src=\x20*\)([/\w\d\.]+)[\\x20]*/%i;

preg_match($pattern, $string, $match); If more than one in the string, use 
preg_match_all().


Now print_r($match); so you can see the result.

Now, read the doc and see why each term is used. Note, I assumed your string can 
have some variation and still be W3C compatible e.g., src=. and

src= , etc. You may need to be able to handle additional variations.

You should always avoid using regular expressions where simple string 
functions will do; regular expressions are a lot slower.


Your problem could easily be solved with something like this:

$firstWord = substr($word, 0, strpos($word,  ));

I think I've got that right, I'm always forgetting if I need to add or 
subtract something from the length parameter :P

The fastest way to do this probably does not involve explodes or regular 
expressions. I would wager that the fastest method would be to do a 
strpos to find cn=, then a strpos to find the next comma (strpos 
supports offsets to start looking for), and then substr out the segment 
you've identified.


However, if cn= is ALWAYS first, it's actually a lot simpler. Then it 
becomes something like this:


$mystring = cn=emailadmin,ou=services,dc=domain,dc=net;
$cnpart = substr($mystring, 2, strpos($mystring, ,) - 3 );

My offsets might be a bit off there, I always get confused with them and 
have to verify by running the code in case I mixed up a zero-based 
character position or something :P

You need to be more specific about:

What is before and after the time string.  It's probably white-space. That so?

Can your HH, values be without the leading zero, e.g., 2:12:15.

Can you be certain that MM and SS will be included.  If the time is entered by users, they can get lazy and give you 
2, for example.


Given the simplest case.  $pattern= %\s(\d\d:\d\:\d\d)\s%;   [% is simply the delimitor, it can be almost any 
thing.] The \s is optional, it says white-space.


$num= preg($pattern, $string [,$match_array])  $time_value= $match_array[1];  $num of matches in case you want to test 
for none or more than 1.

Hi, 

From what i can see you dont even need to call global, as your passing
variables to the function ? this could be causing the script to
confuse itself.

[Jason]

You were right, I removed the reference to global $mac and it started 
working great.  Thanks.  It seems sometimes another set of eyes to catch 
stuff really helps... thanks.

Hi,

Try this (untested) :

preg_match('/^([a-c],)*[a-c]$/', $input);

this will match characters a-c separated by commas. Replace 'a-c' by any
range of characters you like.

I suggest not using a regex.

There are better tools for parsing an email, for example formail.

$email = `formail -x Return-Path`;

If you still like to gather the information without using any tools:

$email = explode( \n , $mailText );

foreach ( $email AS $emailLine ) {
  $emailLine = trim( $emailLine );
   
  if ( strtoupper ( substr( $emailLine , 0 , 4 ) ) == 'FROM' ) {
preg_match( '#^from\s*:\s*([^]+)(([^]+))?#si' ,$emailLine ,$parts );
break ;
  }
}

$name  = $parts[1] ;
$email = $parts[3] ;

But you should consider the following:

FROM: Red Wingate [EMAIL PROTECTED]
FROM: Red Wingate

Which makes working like this a pita.

First of all check who u credit :p
Secondly why don't you just try to fix it yourself?

There was just a typo in the regexp:
- #^from\s*:\s*([^]+)(([^]+))?#si
+ #^from\s*:\s*([^]+)(([^]+))?#si

Hopefully this will help you even more:

?php

/**

 * @return  mixed

function fetchSender ( $mailText ) {
  $mailText = explode( \n , $mailText ) ;

  foreach ( $mailText AS $mailLine ) {

if ( strtoupper ( substr ( $mailLine , 0 , 4 ) ) == 'FROM' ) {
  preg_match ( '#^\s*FROM\s*:\s*(([^]+)(\([^]+)\)?)#si' ,
$mailLine , $parts );

  break ;
}
  }

  if ( is_array ( $parts ) === FALSE ) {
return FALSE ;
  } else {
return array ( 'name' = isset ( $parts[2] ) ? $parts[2] : 'unknown' ,
 'from' = isset ( $parts[1] ) ? $parts[1] : 'unknown' ,

This should work:
^\\ # Don't match if a backslash precedes
\[  # Open bracket
([^\]]+?)   # Text, including whitespace
\]  # Close bracket
By the way, using a tool called The Regex Coach I solved your problem in 
about 10 seconds.  For those having regex problems you might be 
interested in this link, I have found this tool invaluable:

Because the substrings can contain any char-s including
commas. Also I use reg exp not for splitting only but
for validating whether whole string and the substrings
are correctly formatted. Using reg exp requires much less
coding than traditional programming.


 Why not just strip out the braces and explode on commas?  That'll be
 lighter than regexps any day.  If the input is guaranteed to be
 formatted the way you describe, you could do something like:

   $out = explode(,, substr($in, 1, strlen($in)-2));

 Hello all,

 For a while I tried in vain to find a decent regular expression tester.
The closest I found
 was RegExpEditor, by the same people who produce PHPEdit, but I found it
to be slow
 and didn't like its constant bitching about invalid delimiters or some
such thing.

 Anyway, I ended up writing a little tester for Perl-compatible regular
expressions and
 thought I'd share it with you. Maybe it'll come in handy to people who
often need to use
 regular expressions in their projects. Just copy the code below the dotted
line (which
 has Unix line breaks) and save it to a file.

 Cheers,

 Erik

* Jas [EMAIL PROTECTED]:
 Not sure if anyone knows of a good way to match strings of this type...
 00:02:8b:0c:2f:09

 I have tried this but its not working.

 !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}$,$_POST['mac'])

Use the perl compatible regexps instead:

!preg_match('/^([0-9A-Fa-f]{2}:){5}[0-9A-Fa-f]{2}$/', $_POST['mac'])

This searches for XX: 5 followed by XX, where XX is 0-9, A-F, or a-f. I
_think_ the POSIX regexps can do some grouping like this as well, but
I'm not absolutely sure.

[PHP] Re: Regular Expression

[SLanger]

Hello

If you simply want to check if the fields contains Po BOX simply use the 
stripos function or one of the other string functions. They should be 
faster than reg ex.
If you still want to use reg ex I suggest using preg_match since it is 
faster than ereg. 
About your regex:
It will not find occurences of PO BOX in the field. You'd have to use 
something like ereg('PO BOX') without start anchor  '^' or end anchor '$'. 
I think eregi would be better since it is case insensitive.

It seems to me that you don't understand regular expressions so I suggest 
you do some reading up on them.
A very good book about regex is Mastering Regular Expression by O'Reilly 
can't remember the author right now sorry.

[PHP] Re: Regular Expression Help in my PHP! Sorry if wrong group

[Jason Lehman]

I figured out what I was doing wrong.  My regexp should of looked like 
this /a[^]*(Tampa)\/a/ and that made it more specific and kept it 
to that match.

Jason Lehman wrote:
I have a script that turns certain words into links.  That I am having 
no problems with, it is when I want to turn the links back in to plain 
text that I am having the problem.  Below are my examples.  And I know 
my regex is being greedy but I don't know how to stop it from being so 
damn greedy I thought the ? mark would help but it didn't. Any help 
would be appreciated. So here it goes:


The code:

$strStr = This is a href=testUSF/a at a href=testTampa/a.  This 
is a href=testUSF/a at a href=testTampa/a.;
echo $strStr.br\n;
$strStr = preg_replace(/a.*?(Tampa)\/a/,\\1,$strStr);
echo $strStr.br\n;
$strStr = preg_replace(/a.*?(USF)\/a/,\\1,$strStr);
echo $strStr.br\n;

The output:

This is a href=testUSF/a at a href=testTampa/a. This is a 
href=testUSF/a at a href=testTampa/a.
This is Tampa. This is Tampa.
This is Tampa. This is Tampa.

The expected output:

This is a href=testUSF/a at a href=testTampa/a. This is a 
href=testUSF/a at a href=testTampa/a.
This is a href=testUSF/a at Tampa. This is a href=testUSF/a at 
Tampa.
This is USF at Tampa. This is USF at Tampa.

 Is there a soultion using regular expressions?

Yes.  The topics you'll want to look at (in the PCRE chapter of the manual) 
are: case-sensitivity, character classes, capturing subpatterns, and the 
documentation for preg_replace_callback().  One of the things you'll need 
to do is define for yourself what constitutes a word for your purposes.  
Does a single letter word get counted as a word (i.e. i)?  Is there any 
non-alphabet character that can validly appear within the thing you call a 
word (i.e. hi-fi, mst3k)?  This is why there's no single ready-made 
solution.

 Also is there one for removing multiple spaces?
 
 i..e given A   B C D E it would give A B C D E.

Yes.  Again, character classes will be your friend, as will preg_replace().  
Just decide which of the whitespace characters you mean to include in that 
definition of multiple spaces...

preg is much faster/better than ereg.
note the /i at the end of the preg, that makes it case insative, drop the i
if you want it to be case sensative on the match.

  I think I need to use eregi_replace to make the line look like this:
  blah blah blah blah blah a href='#'Link/a blah blah blah blah a
  href='#'Link/a

 Depending on how accurately you have stated the problem, this may work:

 $text = 'blah blah blah blah blah Link blah blah blah blah Link';
 $text = str_replace('', a href='#'XX, $text);
 $text = str_replace('', /a, $text);
 $text = str_replace('XX', '', $text);

 This works, but how can I add a second domain?
 ie:
 

Try:

^[_\.0-9a-z-]+@(domainA|domainB|etc)\.[a-z]{2,3}$

A complete email address check is insanely hard to to if you want to get 
RFC 822 compliant-checking, but who needs that anyways? (fwiw, the regex in 
Mastering Regular Expressions for checking email address syntax is some 
4,700 bytes long.)

)
 $stop = center._ERRORINVEMAIL./centerbr;

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!
