The reason that a single \ in front didn't work is that \ is ALSO
special character for ' in PHP, and it just escapes the - so that you
have NOT sent \- to EREG, but sent it the same thing you were sending
it before you added \

You would need \\ inside of '' (or "") in PHP to get a single \ sent
to EREG which would then be used by EREG to escape the -

'...\\- ,/'

PHP takes \\- to produce \- which EREG takes to produce [character -]
instead of [range operator -]

You should probably review the "strings" page at the beginning of the
PHP manual.

Actually, I tried that, but it didn't work.  It still saw the hyphen as 
an operator.  The other thing about this is that the hyphen is followed 
by a space, so that it's asking for a range between the period and the 
space, which you can't do, since the space character has a lower ascii 
value than than the period.  The space is more obvious in a monospaced font.

It means that the bit that hs .- , above makes ZERO sense, because ,
comes before . in ASCII, so you can't do that range you just tried to
do.

Of course, you weren't actually trying to do a RANGE, but when you
tacked ' ,/' onto your pattern, you weren't paying attention to the
fact that - has to be at the very end, or very beginning, or (maybe?)
escaped so that EREG knows it's not a RANGE you are defining, but a
single character in the character set.

I agree with the first part, that it is in many cases better to use the 
Perl Compatible Regular Expressions (PCRE, preg_*) than the POSIX 
compatible ones (ereg[i]_*). However, I don't quite get what you mean by 
"extension is useless" ? What extension...?? and why would it be 
useless? (useless in what way?)

RE: [PHP] Eregi error

[Peter Lauri]

Not sure, but I don't think you should escape all those characters inside of
the character class. I might be wrong. However, that might not have anything
to do with the error. But I do think you need to escape the / in the end...
And the - you should have in the beginning of the character class, otherwise
it will be treated as a range.

Why don't you just explode() on '.' and then pick the bits you need?

Ah, yes, I guess I had it that way because there are no hyphens in top

would exclude them if there were more elements.
Thanks for pointing that out.

You're only allowing hyphens in the first part of the address after the @
symbol, though, before the first period. Maybe your regex should be:

@([a-zA-Z0-9-]+\.)+[a-zA-Z.]

Just noticed that your period is not escaped, either, so you're actually
matching any character with the one that's outside of the [ and ] character
classes.

No.  You've only allowed for hyphens in the first element after the @ sign

I am fetching a web page, and attempting to parse

times in the past with no problem.  The only
difference this time is the file that I am parsing is
much larger.  The HTML file is about 42kb in size
(usually I only parse ~4kb worth).  In the web
browser, the script seems to just shut down, but
reports no errors, not even to the web server logs. 
Is there some specific max size that it can accept or
a setting in php.ini I need to modify?

Thanks
hi,

i don't think, that 42k is too much for the size of your file. mut maybe 
php simply times out while parsing? there is a php.ini-parameter 
max_execution_time and a runtime-function set_time_limit(). try 
set_time_limit(0) at top of your script fo debugging.

also take a look at preg_* functions instead of ereg_*. they are said to 
be much faster.

well, for one thing, don't use ereg. Use pcre, as it is faster.

preg_match('/^[a-zA-Z0-9]{5,16}$/',$blah);
that will validate a password containing only upper or lowercase

So "a" is a good password?

well, for one thing, don't use ereg. Use pcre, as it is faster.

preg_match('/^[a-zA-Z0-9]{5,16}$/',$blah);
that will validate a password containing only upper or lowercase letters 
and numbers, between 5 and 16 characters.

/^[\-\d]+$/ should match a string of just digits and dashes.

If the regexp matches, it is a valid email, so you need ! in front of it.

Re: [PHP] eregi problems

[dan radom]

My main cnocern at this point is that the eregi is being totally ignored.  I just want 
to make sure the email address is in a valid format, not that it is a valid email 
address.  I'll look at validEmailFormat as well, but I don't understand why it's not 
even being examined.

Re: [PHP] eregi problems

[Justin French]

Dan,

I'll give you a little piece of advise that was given to me a little while
back on this list:

Go to http://www.killersoft.com/ and grab a copy of the validateEmailFormat
program.


PHP4 translation of Jeffrey E.F. Friedl's definitive Email Regex Program
from O'Reilly's Mastering Regular Expressions.  This function is used to
confirm if an e-mail address adheres to the RFC 822 specification for
internet email addresses.


Rather than trying re-invent the wheel, why not use something that conforms
closely to specs, and is widely accepted by many development groups.


All you'll have to do is something like (function names and filenames may
not be right):

please enter a valid email address";
}
?>


Side topic:  of course, you aren't checking for a valid email address at
all, your checking to see if the email address LOOKS valid.  You're not
checking to see if the address is attached to an email box, or furthermore
if there's anyone at the other end to open/read your email... you're just
validating the appearance of the address to fall within RFC 822 specs.

Subsequently [EMAIL PROTECTED] and [EMAIL PROTECTED]
will both return valid.


The only way to ensure an email address is truely valid is to send an email
to it, and have them respond... indicating that the address is linked to an
email box and furthermore, someone opened the email, read it, and responded.

Even then, this could be done by a robot I guess.

It looks like you're trying to match IP addresses? In which case shouldn't you 
have "echo $array[3];" as well? 

Anyway that's besides the point, what is the format of your file?

Re: [PHP] eregi() against a binary file?

[Miguel Cruz]

According to the manual, the ereg functions are not binary safe. The 
superior-in-every-way preg functions are. Perhaps you could try using 
preg_grep instead.

$result = preg_grep('/' . preg_quote($imagename) . '/', $file);

You may find that strstr or something is even simpler.

One problem (syntax issues aside) is that it doesn't seem to be checking
for anything remotely similar to a valid email address.

Here's what we use. Not 100% perfect but closer than most, I think:

function validate_email ($addr)
{
  return

preg_match('/^[^\'"\s,;]+@([a-z0-9]+[a-z0-9\-]*\.)+[a-z0-9]+[a-z0-9\-]*[a-z0-9]+$/i',
  trim($addr)));

Yes, and those changes are codified into new RFCs which eventually become
standards. By all means have a look at RFC 2822 which, if passed into use,
will obsolete 822.

Sure, and if a web server is set up to respond to a request like:

   SPLEARGH www.boogermax.com/greebles ? 888 *** 3424235667

then web browsers could send it and get something in return, but it 
doesn't mean it's a valid HTTP request.

"Properly formatted email address" is a term whose meaning derives from a
prescriptive, rather than descriptive, definition. A properly-formatted 
email address is one which has been properly formatted in accordance with 
the rules governing mail addressing, and nothing any more arbitrary than 
that.

Why even look for an @ sign then? I can address a message to 'mnc' and it
will arrive just fine - within my zone of control.

The reason that we use standards is to ensure that hardware and software 
from various vendors can communicate with each other without unexpected 
results. As soon as you start giving that up, you subdivide the internet 
into smaller zones of mutual compatibility. About 99.9% of the time, there 
is no constructive reason for doing it. Given the flexibility already 
allowed in email addressesing, I certainly don't see this as one of the 
exceptions.

Re: [PHP] eregi(mail)

[Kevin Stone]

As we all know ARPA is thet university network, funded by the government to
build an information infrastructure that eventually became the internet we
have today.  But the standards for text messaging within the ARPA net have
been added to over the years in order to accomodate ever expanding
requirments.

For example I have read that a valid email needn't necessarily require
anything before the @ symbol.  The ARPA RFC specifically states that it
does.  But <[EMAIL PROTECTED]> can be just as valid as <@foo.bar.com>  if the the
domain resolves and the server is setup to parse from a catch all account
named ''.  Is this not true?

If this is true then eregi(/^[a-z0-9]+/, $email ) wouldn't necessarily be
valid.  We could then say that eregi(/^[a-z0-9]*/, $email) is pointless
becuase if nothing has to be there then there isn't any reason to look for
it.  And thus we return to the original assertion that ereg('@', $email) is
the only way to know that the string is a properly formated email address.

So why even validate that format beyond the most basic rules (@, length, and
invalid characters)?   The result of which is useless, unless the address is
sendable, in which case the string format is irrelevant.

Re: [PHP] eregi(mail)

[Steve Buehler]

Either Google is wrong (probably) or they are now allowing things like 
spaces into an email address.  There are actually several things that are 
not allowed in a standard email address.  Here is the code that I use.
ereg('^[-!#$%&\'*+\\./0-9=?A-Z^_`a-z{|}~]+'.'@'.'[-!#$%&\'*+\\/0-9=?A-Z^_`a-z{|}~]+\.'.'[-!#$%&\'*+\\./0-9=?A-Z^_`a-z{|}~]+$',
 
$subarray))
I am honestly not sure where I got this code, but it has always worked for 
me and I have not found any YET that are good address that this kills.  I 
have also not found any bad ones YET that this lets through (unless the 
domain or user doesn't exist, of course).

Those characters don't conform to the RFC.

Miguel, thanks for posting the RFC (in the prior email).  That's what I based my ereg 
on (as shown in yet another earlier email).

If I'm reading it correctly, this will let invalid addresses through. The
domain component (after the @ sign) can only contain a-zA-Z0-9\.\-

There is a format. See:

Re: [PHP] eregi(mail)

[Kevin Stone]

I had always been suspicious about email validators so I did a big long
search on Google about standard address formats.  It turns out that aside
from the @ symbol emails have no standard format whatsoever.  So ereg('@',
$email) is really the only functional email validator.

You also have to think about what kind of email validation you need.  Do you
really need to control the format of the emails being stored in your
database?  Or do you need to control the validity of the emails being stored
in your database?  There is a big difference.  A valid email address isn't
necessarily one that is formated in the way you expect.  It is one that is
active and can be mailed to.  There are a number of techniques you can use
to determine that.

Well.. anyway sorry for going off on a tangent there.  In your search for an
email validator you got a bit more information than you expected.  I hope it
was useful in some tiny miniscule sort of way.  :)

Well, it currently is an invalid email address (NXDOMAIN fdsf.net).
Perhaps the functions you've tried are doing lookups on the domain portion
of the address?

There's no ambiguity here since parentheses aren't legal in variable names, 
so the curly braces are just excess.  Given the braces' significant as 
special regex characters, it can be a confusing distraction in this 
context, especially for newbies trying to grasp simply regex syntax.  
Better to save the braces for where they're needed to tell the parser or 
programmer how to interpret ambiguous code.

Don't they get removed by the parser's handling of "double-quoted" strings 
long before anything makes it to preg_match()? 

I almost always use the braces when inserting variables inside string 
literals, just to avoid any chance of ambiguity.

Leave out the braces.

preg_match("/$start(.*?)end/", $rf, my_var);
  -or-
preg_match("/$start(.*)end/U", $rf, my_var);


(And make sure the value of $start either doesn't have any regex special 
chars, or is using them intentionally, or has them escaped 
.)

Try preg, which is faster and gives you more control (here the ?

preg_match("/{$start}(.*?)end/", $rf, my_var);

The only thing that will match that regex is a single alpha character.

Try "^[[:alpha:]]+$" (I added a plus) to match one or more.

[Danny Shepherd]

Try:

if (!eregi('^[a-z_\-]{0,}$', $_POST['vpis_ime']))
  echo "wrong char";

That'll sort it for everything except [ and ], which I can't find any way of
checking for :-( Anyone else have any ideas?

HTH anyway.

eregi('_[0-9]{4}.jpg$', $file_name)

should be

eregi('_[0-9]{4}\.jpg$', $file_name)

. is a spcial character(means every character) and has to be backslashed if
you want it's normal meaning

I hope I'm reading right... it seems you want to filter OUT files with
the extension '_.jpg' the above check appears to be filtering out
everything BUT these files. I think you want the following check:

if( $file_names != "."
&&
$file_names !=".."
&&
!eregi( '_[0-9]{4}\.jpg$', $file_name) )

$pattern = "[a-zA-Z0-9_\-]+";
this is meaning :
One word containing a-z or A-Z or 0-9 or "_" or "-" with a length of
minimum 1 character !

Regular expression is not so difficult !
Check the php documentation !

Re: [PHP] eregi, ereg or smth. else???

[bvr]

You don't need regular expressions for this.

To match case insensitive, just upper or lower case both strings
and use strpos() to find an occurence. Now you allready have the
position of the match it'll be easy to get that part of the string.

I suggest you substr() it into 3 parts and put the  and  in between.

Not quite sure what eregi has to do with it - perhaps I'm missing something.

Would the nl2br function help?

Hi Sait,

if ( ereg("[^0-9a-zA-Z\_\-]", $user_input) ) {
  //invalid char detected
}
else {
  //input contain only allowed char
}

just add all your valid char in the pattern, and dont forget
to escape the char which has special meaning in regex.

Re: [PHP] eregi

[mike cullerton]

i realize a solution using strspn/strcspn was offered, but you asked for
eregi :)

anyway, i use ereg, but i think this should work

eregi("^[a-z0-9_\-]+$",$string)

notice that i had to escape the dash with a backslash

the plus sign forces atleast one character. you can use {x,y} in place of
the plus to force atleast x characters but no more than y characters.

Re: [PHP] eregi

[Tim Ballantine]

"Returns the length of the initial segment of str1 which does not contain
any of the characters in str2."

I realise that i could see if this matches with the length of the entire
word, and is there a way to get it to compare the word by the legal
characters, because the amount of illegal symbols, including different
language symbols (french for example) will be too high for me to list.

Is there anything which doesnt use length? And something like eregi, because

Can't tell you what your problem is, but FWIW here is what I use to do 
the job - if you can extract some useful bits from that

  $exists=true;
endif;

if($exists):
  $title .= $contents[$i];
endif;

if(eregi("", $contents[$i])):
  break;
endif;

  }   /* End FOR */

  /* Get rid of end of line in case title tag is spread over multiple 
lines */
  $title = eregi_replace(10, "", $title);
  $title = eregi_replace(13, "", $title);
  if( (empty($title)) || (strtoupper($title) == "")):
$title = 'Research Centre for Injury Studies';
  endif;
  /* Clear the slashes, in case there are wonky chars in the title 
(Thanks, James!) */
  return stripslashes($title);
