Ash, Thats not true. In character class only meta-characters are \ ^ - [


And the dash only when it's not the first, or the last in the class.

Eclipse/Zend Studio is so full of options that you can miss a lot of them. 
Another downside of the little arrow thing is that it doesn't recognize arrays, 
which is obvious because arrays can only be read on runtime, well, same thing 
as objects.

Yeah I know it displays a lot of information, but I use it sometimes and it's 
the only way I know to display all variables, arrays and stuff in a neat and 
nice way. You can also install xDebug and use the included debugger in ZS, but 
sometimes using a simple print_r is faster.

Nope. Nothing there. Those templates are for when you create new blurbs of
code, not modifying existing code.

There is a formatter however, sadly it doesn't have an option to force these

Many people mistakenly think that short version is going to be deprecated
away. It is not. The PHP Devs have already clarified only the "http://www.php.net/manual/en/ini.core.php#ini.short-open-tag

> Also the short if version "1 == 1 ? True : false" should be replaced if
i'm correct.

You are not. ;-)

The Ternary operator statement would never go away. It is a standard
comparison operator in pretty much any language and would be completely
stupid of the PHP Devs to deviate that far from the norm.

http://php.net/manual/en/language.operators.comparison.php

Plus I love that operator and use it quite frequently. However, I use it
like this just for clarity:

echo "your result is ".((1 == 1) ? 'true' : 'false').'';

> Second question: zend studio displays all variables used by a script by

I've used ZS for 4+ years now, and comicaly have never even used those
little down arrows next to a file. HAHAH! Good to know. Although it is a
little strange as they seem to only be where you use a "=" assignment. It
doesn't know about "->" or other instances of that variable (like if you
echo it or something). But still could prove useful.

Whoa nelly! That prints out WAAY too much information ;-)

Re: [PHP] Regex pattern for preg_match_all

I tried your pattern but it didn't capture all of my new test cases.
Also, it captures the single/double quotes in addition to the

Below is the new pattern with the new sample test cases that I got it

Hi Tommy,

This is why you shouldn't mix regexes and HTML/XML, especially when you 
are not sure that you are working with valid/consistent html.
A great/fun answer has been posted on StackOverflow about this at 
http://stackoverflow.com/questions/1732348/regex-match-open-tags-except-xhtml-self-contained-tags/1732454#1732454


You could easily break any regular expressions solution by adding some 
valid comments, see example here : 
http://stackoverflow.com/questions/1357357/regexp-to-add-attribute-in-any-xml-tags/1357393#1357393


You really should consider using a XML parser instead for this kind of job.

Here is a simple sample that matches your example :

$html = $oTidy->repairString($html,array("clean" => true, 
"drop-proprietary-attributes" => true));

unset($oTidy);

$matches = get_links($html);

function get_links($html) {

// Create a new DOM Document to hold our webpage structure
$xml = new DOMDocument();

// Load the url's contents into the DOM
$xml->loadHTML($html);

// Empty array to hold all links to return
$links = array();

//Loop through each  tag in the dom and add it to the link array
foreach($xml->getElementsByTagName('a') as $link) {
$links[] = array('url' => $link->getAttribute('href'), 'text' 
=> $link->nodeValue);

}

//Return the links
return $links;
}
?>

Regards,
Yann

Not entirely sure what your input data is, as I'm guessing one or more
mail programs may have added line breaks. When I run the code I get no
matches at all - so I'm guessing you might have different input on
your end. More specifically, I'm also guessing you have line breaks on
your end, but not equally distributed - which would explain the one
hit.
 Apart from that, there are a couple of things I'd rework in your regex:

%]*>(.*?)%ims

* added modifier to whitespace at first
* allowing for any character not followed by href (non-greedy)
* match the href
* use proper alternation
* capture anything inside the  tag, non-greedy
* match with a closing  tag

Results:

Re: [PHP] Regex pattern for preg_match_all

[Simon J Welsh]

As far as I can tell, your problem lies in [^href]*. That will match any 
characters other than h, r, e or f, not anything other than the string href. 
Consider replacing it with [^>]*?. The ? makes it non-greedy so it will stop as 
soon as it can (when it matches the first href) rather than as late as it can 
(when it matches a >)

I wouldn't try and do this with a regex, it would just become too
complicated. What about people with no middle name, or multiple middle
names? How do you deal with double-barrelled names like John
Walter-Smythe Doe? You would be far better off using multiple input
boxes for this sort of thing, and then format it as required when
outputting the data.

Bah, you're absolutely correct.  Force of habit with the commas.
I didn't even notice the sample test cases I put into that test array
didn't check for more than the number of digits per field, either.
Good catch, Jim, and Happy New Year.

Actually...

Specified here [1] it says that the {1,} is the same as '+'.  I think you should
drop the comma.  If you don't this would be valid 844-2345-123456

^[2-9]{1,}[0-9]{2,}\-[2-9]{1,}[0-9]{2,}\-[0-9]{4,}$

should be

^[2-9]{1}[0-9]{2}\-[2-9]{1}[0-9]{2}\-[0-9]{4}$

Not quite.  Plus, all ereg* functions have been deprecated for

In the US and Canada, though, there's [as of yet] no difference
between landline, mobile, VOIP, fax, toll-free, premium (900), et
cetera.  Again, that's why I wrote out the example the way I did,
which conforms to NANP (NPA/NXX) standards.  It's the only suggestion
so far that will work completely (which sounds cocky, but screw it,
it's the last Friday of the year  ;-P).

AFAIK, they too vary from country to country.  Swiss mobile numbers are
07[6789] NNN, the latter usually written as NNN NN NN, but also
often in a way that will help remembering the number.  
Danish mobile#s are the same as land line numbers, no area code, just
.

This expression will be used to search a database which will contain 
patient data resulting from medical research.  At the initial visit a 
medical record number will be assigned to the patient.  Other 
information will be collected at that point; eg,  the telephone number. 
At subsequent visits, the patient will be referenced by his/hers medical 
record number.  If the patient either forgot their clinic card, or 
cannot remember their medical record number, a search will be 
performed.  One of the many parameters that can be used in the search is 
the phone number. It is easier if all the data has a fixed format.  The 
form for  the initial visit will use a regex that will validate the 
phone number. As  the research will be performed in the US, only US 
numbers have to be validated.


Ethan,

I think you misunderstand, I'm saying that regardless of which format 
you use within the system, users could enter phone numbers as 
"1231231234" "123 123 1234" "123-123 1234" or any variant they like, 
that's completely orthogonal to how you validate and save the data, in 
all of those cases all you need to do string non-numeric chars to 
validate, you may also find your indexes work that bit quicker storing 
numbers rather than specially (and needlessly) formatted string.


Likewise on the way back out, when presenting the numbers to users, all 
you need to do is string format them.


Follow?

Just keep in mind that invalid numbers will also pass that check,
such as 000-000- or 123-456-6789.  That's why my example was a bit
more involved.

You can't, phone numbers are more complex then that. You could use 
\d{3}-\d{3}-\d{4} to match that basic pattern for all numbers though.

Really, this isn't a PHP question, but rather one of regular

[Alexis]

Why not have three separate fields for each part, as that way you don't 
need to bother about how the user separates them, as trust me, if they 
can break it, they will.
I have found it is best to always limit the amount of free entry you 
permit a user, as that will drastically cut back in data entry validation.

That did the trick.  Thanks Ash you are awesome!

Also thanks Jim for your suggestion.  I may move to SimpleXML if the project
grows much bigger.  But for now I was looking for a nice one liner and this
is it.

I think it's probably the first ? in ([^\"\']+?)

Remove that and it should do the trick

I appreciate the help.  However, when try this I only get the first

I just changed your regex a bit. What your regex was previously doing
was matching everything from the first quote after the href= right up
until the first > it found, which would usually be the one that closes
the opening tag. You could make it a bit more intelligent if you wished
with backreferencing to make sure it matches against the same type of
quotation character it matched as the start of the href's value.

Looking at this document from an XML standpoint, I could see doing this rather
easily.  Without having to use regex.  You might look into using DomDocument and
simpleXML to complete the task.

Asunto: [PHP] regex for multiple line breakes

Hi there,

I am trying to remove multiple linebreakes from a textarea input. Spammers tend 
to insert multiple line breakes. The problem is, that I want to allow 2 line 
breaks so basic formating should be allowed.

I am doing this by regex:
$data[txt] = preg_replace('`[\r\n]+`',"\n",$data[txt]);

I would need a regex that allows \r\n\r\n, but not more than this.

Thank you for any help,

Merlin

You still have an issue with your regex:

$data[txt] = preg_replace('`[\r\n]+`',"\n",$data[txt]);

Even if you replace the + with a {2,} you are asking it to match any one
of the characters in the square brackets twice or more and replace it
with a single \n. If your line breaks actually do consist of the \r\n
pattern, then the {2,} will match those two characters, not two sets of
those characters. You might be better off replacing all \r characters
with an empty string, and then matching against the \n character only.

Thanks,
Ash

Thank you. That worked!
$data[txt] = preg_replace('`[\n]{3,}`',"\n",str_replace("\r", 
"",$data[txt]));

Re: [PHP] regex for multiple line breakes

[Fernando Castillo Aparicio]

Right. I saw it later. To be completely multiplatform I'd use a grouping: 
(\n|\r|\r\n){2,}. If I'm not wrong, these are all the actual formats for a new 
line.

If we replace \r with a newline we could fail if the text comes from a MAC OS.

You still have an issue with your regex:

$data[txt] = preg_replace('`[\r\n]+`',"\n",$data[txt]);

Even if you replace the + with a {2,} you are asking it to match any one
of the characters in the square brackets twice or more and replace it
with a single \n. If your line breaks actually do consist of the \r\n
pattern, then the {2,} will match those two characters, not two sets of
those characters. You might be better off replacing all \r characters
with an empty string, and then matching against the \n character only.

Re: [PHP] regex for multiple line breakes

[Merlin Morgenstern]

That sounds very logical but does not work unfortunatelly.
The result is the same. It removes all linebreakes but one.
I would like to pass this one:

-
first line

second
third
-

But not this one:
-
third




forth

Asunto: [PHP] regex for multiple line breakes

Hi there,

I am trying to remove multiple linebreakes from a textarea input. Spammers tend 
to insert multiple line breakes. The problem is, that I want to allow 2 line 
breaks so basic formating should be allowed.

I am doing this by regex:
$data[txt] = preg_replace('`[\r\n]+`',"\n",$data[txt]);

I would need a regex that allows \r\n\r\n, but not more than this.

Thank you for any help,

Merlin

You prolly have already been here:

But if not, that site is certainly useful for all things regex.

Sorry I can't be of more help for your specific question.

Hi Merlin,

I think the pattern you're looking for is '/[a-zA-Z0-9]/' which will  
match all alphanumeric characters.

Yes, thank you.  I was fiddling before I got your post and I came up

Shawn,

First thing I see--your first capture group doesn't include the $, and
so your final capture group will always fail given your current $out
(because it's looking for {/sites} instead of {/$sites}). Also, your
{} are outside of your capture group in \1, but inside in \3. Here's
what I came up with:

$out = '
{$sites}

   
   {Site.id}
   

{/$sites}';
$matches = array();
preg_match_all('#{(\$[^}]+)}(.*?){(/\1)}#s', $out, $matches);
print_r($matches);

Produces this:

Array
(
[0] => Array
(
[0] => {$sites}

   
   {Site.id}
   

{/$sites}
)

[1] => Array
(
[0] => $sites
)

[2] => Array
(
[0] =>

   
   {Site.id}
   


)

[3] => Array
(
[0] => /$sites
)

)

Keep in mind, I had to view the page source in order to see the HTML
tags, but it showed me everything I expected to see.

there is, your control-Z is not a Z at all, and it's only printed as ^Z
so you can see it ... it's actually a non-printing char.

try this regexp for stripping control chars:

RE: [PHP] Regex

[Jesse.Hazen]

Bruce,

Sure thing. So basically what I am trying to accomplish is when this
script runs, a menu is displayed to the user, it looks somewhat like
this:



Welcome
To continue, please select your game mode.

[Mode]  [Description]
A.) Mode A
B.) Mode B
C.) Mode C
D.) Mode D
E.) Mode E
F.) Mode F
Q.) Quit.

To begin, please type the mode letter.

Mode:

 

Then, the below lines of code come into play:


public function getSelection() {

$choice =
$this->validateChoice(trim(strtoupper(fgets(STDIN;
return $choice;

}

private function validateChoice($choice) {

$choice = preg_replace("/[\x00-\x1f]+/","",$choice);
return $choice;

}


So now the script is waiting for user input. The next thing to happen,
right after this code, is:


private function validate($choice,$display,$input) {

$valid = false;
while(!$valid) {

switch($choice) {

case "Q":
$display->writeCredits();
sleep(4);
exit(0);
case "A":
$valid = true;
break;
case "B":
$valid = true;
break;
case "C":
$valid = true;
break;
case "D":
$valid = true;
break;
case "E":
$valid = true;
break;
case "F":
$valid = true;
break;
default:
$display->writeInvalidChoice();
$choice =
$input->getSelection();
break;

}

}

return $choice;

}



Now, this is where the script loops infinitely. But, this is only the
first method which validates user input. There are several others.
Basically, my script should accept user input, strip anything that will
not be needed (like anything other than letters and numbers) and then
allow the user to proceed, where the script checks to see if the
numbers/letters they entered correspond to the menu's in any way.

Everything in the script runs perfect, except the fact that the control
statements print infinitely. And while I am sure there is something I
could do to this method to make it not loop infinitely, I would also
need to do this to several other loops. 


 
 
Thanks,

Hi,

 

Brand new to regex. So I have a cli which runs a regex on users input,
to make sure that only 0-9 and A-Z are accepted. It should strip
everything else. My problem is that when you press control-Z (on
Windows; I have not yet tested this on linux, and I will, but I would
like this to be compatible with both OS's) it loops infinitely saying
invalid data (because of the next method call, which decides what to do

ensure that control commands are stripped, here?

$choice =
$this->validateChoice(trim(strtoupper(fgets(STDIN;

}

 

private function validateChoice($choice) {

 

$choice =
ereg_replace("/[^0-9A-Z]/","",$choice);

return $choice;

 

}

Thanks, but this regex did not seem to work for me. At least, not on
Windows. I will not be able to test on linux for a few hours. 

I spoke too soon yesterday, too. Control-Z is a problem on Windows, and
not on Linux. However, on linux, control-D is a problem.

The actual value is 0x1A, and it maps to the ASCII SUB (substitute)
control character. The carrot-Z (^Z) representation is how Unix CLI
software would display it. Many control codes that didn't actually do
anything were printed on the terminals with the carrot prefix. Sometimes
codes that did trigger a function in the terminal would be printed that
way to prevent the function from triggering.

Control-Z is a left over from the CP/M days. It was used to mark the end
of text files, since the original file allocation table (FAT) only
tracked the number of clusters assigned to a file. Some MS-DOS and
MS-Windows applications still tack it on to the end of files. I guess
that's their idea of backward compatibility.

there is, your control-Z is not a Z at all, and it's only printed as ^Z
so you can see it ... it's actually a non-printing char.

try this regexp for stripping control chars:

/[\x00-\x1f]+/

Ctrl z suspends the current process running in the shell in linux.  Not
sure about winbloze.  Probably sends an escape char of some sort.

hi...

if you haven't solved your issue... can you tell me in detail what you're
trying to accomplish? what are the steps to running the script?

Hi,

 

Brand new to regex. So I have a cli which runs a regex on users input,
to make sure that only 0-9 and A-Z are accepted. It should strip
everything else. My problem is that when you press control-Z (on
Windows; I have not yet tested this on linux, and I will, but I would
like this to be compatible with both OS's) it loops infinitely saying
invalid data (because of the next method call, which decides what to do
based on your input). So, here is the input code. Is there a way I can
ensure that control commands are stripped, here?

 

 

 

 

 

public function getSelection() {

 

$choice =
$this->validateChoice(trim(strtoupper(fgets(STDIN;

return $choice;

 

}

 

private function validateChoice($choice) {

 

$choice =
ereg_replace("/[^0-9A-Z]/","",$choice);

return $choice;

 

}

 

 

 

I have tried a ton of different things to try and fix this. Tried
/\c.|[^0-9A-Z]/, and many variations of \c and the [^0-9A-Z], to no
avail. I also tried using both preg_replace() as well as ereg_replace().
I spent a lot of time on the regex section of the PHP manual, but I am
not finding anything. Any advise on how to accomplish this?

 

 

 

Thanks,

Nistan,

Just got home, tested on linux. No problem on linux, the control-z just exits. 
I may just go ahead and post my issue to the PHP windows list to see if 
anything comes up, and not worry if it doesnt. I appreciate the help very much

Nitsan,

 

Not a problem, thanks for the help. So, it is printed as ^Z. However, I
created a little test.php script to accept input and print it back to
me. So, I used control z as my test, and it simply printed a line, and
that's all. So, then I input control z, and then had it print a letter
right after ("a"), and it was just the letter a. no whitespace, no
breaks, nothing. 

 

I even tried one more thing: in the loop (not in the code below) I put
unset($choice), right above where it tells the user their input is
invalid and asks for it again. Even this did not change anything: when
pressing control - z, it looped infinitely.

 

I assumed that \c would be the regex to mend this, as the php manual has
this as "control-x, where x is any character". I even tried every
variation of this, with a key combination like \cZ, or \cz, or \c[zZ],
yet it still does not catch it.

 

 

 

 

Thanks,

 

Jesse Hazen

RE: [PHP] Regex

[Jesse.Hazen]

Nitsan,

 

Thank you very much for the input. However, I just gave this a try and
it still did not strip the control-Z. Therefore, it is still hitting my
loop later and looping infinitely. I am sure I could mend that by
working something into that loop, but there are several loops I would
need to do this on. If I can stop the command at this method, then the
entire script will run perfectly.

 

 

 

 

Thanks,

Mike,

Certain characters are considered "special" in RegEx. The $ means "end
of the line," so it must be escaped to avoid confusing its meaning. I
was not sure it had to be escaped within a character set [], but that
may very well be the case. Try this:

$regex = '/function\s+[-_a-z0-9]+\s*\((\s*\$?[-_a-z0-9]+\s*,?)*\s*\)/i';

The word "function" is followed by 1 or more spaces (or tabs). The
function name [-_a-z0-9] can be a combination of alpha-numeric
characters, underscore, and dash. Then, there is optional whitespace
between the name of the function and its parameters. The opening
parenthesis "(" for parameters has been escaped (as has the closing
parenthesis). Then, in a repeatable capture group, the parameters can be
grabbed: Indefinite whitespace, an optional $ (because maybe you're not
using a variable, eh?), one or more alpha-numeric, underscore, or dash
characters, followed by indefinite whitespace and an optional comma (if
there are more arguments). After any number of instances of the capture
group, the regex continues by looking for indefinite whitespace followed
by the closing parenthesis for the function text. The "i" switch at the
end simply means that this regex pattern will be treated as
case-insensitive ('APPLE' == 'apple').

If you're not worried about actually splitting up the function
parameters into capture groups, then you can just use a look-ahead to
ensure that you grab everything up till the LAST parenthesis on the
line.

$regex = '/function\s+[-_a-z0-9]+\s*\(.*?\)(?=.*\)[^)]*)/i';

That one probably needs to be tweaked a bit in order to actually grab
the last parenthesis (instead of just checking for its existence). If
you're willing to trust the text you'll be searching through, you can
probably avoid that "last parenthesis" rule altogether, and make a lazy
regex:

$regex = '/function\s+[-_a-z0-9]+\s*\(.*?/i';

Once you get to the opening parenthesis for the function parameters,
that last regex assumes that the rest of the line will also include that
function declaration, and just grabs everything left. If you are using a
regex setup to where the dot marker can also consume newline or carriage
return characters, just throw a "$" at the end of the regex (before the
flags part "/i") in order to tell it just to grab characters until it
reaches the end of the line:

$regex = '/function\s+[-_a-z0-9]+\s*\(.*?$/i';

These are all untested, but hopefully I've given you a nudge in the
right direction. If you are still getting strange behavior out of your
PCRE engine, then perhaps you have a different version installed than
what I'm used to--all of the above should work (perhaps with some very
minor changes) in PHP.

Re: [PHP] RegEx to check for non-Latin characters

[Behzad]

Thanks everyone. I guess I find the answer:

*// return true if the $str ONLY consists of Arabic characters and
space-character
public function isArabicString($str)
{
return preg_match('/^([\p{Arabic}]|\s)*$/u', $str);
}
*
PHP 5.1.x or higher is required.
@see: http://www.regular-expressions.info/unicode.html

Cheers,

Re: [PHP] RegEx to check for non-Latin characters

[Yeti]

Hi Behzad,

I would try a different approach ...

EXAMPLE (UTF-8):

http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";>


Persia


';
}
function mbStringToArray ($string, $encoding) {
   $strlen = mb_strlen($string);
   while ($strlen) {
   $array[] = mb_substr($string,0,1,$encoding);
   $string = mb_substr($string,1,$strlen,$encoding);
   $strlen = mb_strlen($string);
   }
   return $array;
}
?>



As you can see I'm using the multibyte string functions [1] and split
$username into a character by character array.
Then I use strlen() for which an UTF-8 char has a length > 1. Note:
This might change with PHP6.
It also does not check for Persian characters only yet. You would have
to try something like this ...

EXAMPLE (UTF-8):

http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd";>
http://www.w3.org/1999/xhtml";>


Persia


';
   if (mb_strpos($chars, $char, 0, $encoding) !== false) echo $char.' is
a Persian character';
}
function mbStringToArray ($string, $encoding) {
   $strlen = mb_strlen($string);
   while ($strlen) {
   $array[] = mb_substr($string,0,1,$encoding);
   $string = mb_substr($string,1,$strlen,$encoding);
   $strlen = mb_strlen($string);
   }
   return $array;
}
?>

In a PCRE regex, [\x80-\xFF] will find all extended ASCII chars. Or,
if you wanted all ASCII chars, you could use: [\x00-\xFF] That would
catch space and punctuation as well though. Or you could amend it to
suit. It's in hexadecimal (ie FF == 255)

It surely is a valid localhost email address, but what most people
(and the OP) usually need is to validate a full email string with a
local and a domain part.

What should be valid email addresses according to RFC 2822 [1]:
!#$%&*+-/=?^_`{|[EMAIL PROTECTED]
"@"@example.com

Not valid email addresses:
"\"@example.com
@@example.com
- [EMAIL PROTECTED]

Valid email addresses according to the Multipurpose Internet Mail
Extension (MIME) [2]:
[EMAIL PROTECTED]
[EMAIL PROTECTED]

So for people who got to write code that also works on PHP4 it is not
very easy to validate an email address.
Even nice regex attempts like [3] fail since more and more mail
servers support the MIME hieroglyphs.
That's why I was pretty excited about imap_rfc822_parse_adrlist(),
since it runs in PHP4 if installed.
Which clearly is no substitute for the PHP5+ filter functions [4].
If it's just my brain farting and there actually then tell me.

Re: [PHP] Regex validation

var_dump(imap_rfc822_parse_adrlist('"! # $ % &  * + - / = ? ^ _ ` { | } ~"', 
'')); 



This looks like a valid localhost email address to me...



What's wrong with it?

:-v



You may want to check that "host" is non-empty, if you do not expect any 
localhost users, and fail on that condition, however.

Re: [PHP] Regex validation

[Yeti]

After "ceo" posted about the imap function I was eager to try it out
and got rather disappointed pretty soon.
imap_rfc822_parse_adrlist() should not be used for email validation!

EXAMPLE:


The above code will output:

array(1) {
  [0]=>
  object(stdClass)(2) {
["mailbox"]=>
string(36) "! # $ % &  * + - / = ? ^ _ ` { | } ~"
["host"]=>
string(0) ""
  }
}

Although
"! # $ % &  * + - / = ? ^ _ ` { | } ~"@example.com
would be a valid email address!

Without the '@example.com' it is not.

Have a look at the user comments at [1], where one user has further examples.

Are they not base64 encoded? I have had issues in decrypting elements that

How is anything but your webserver decrypting the $_POST data?  PHP

Re: [PHP] Regex validation

[VamVan]

SSO process:

$_POST the Email Address and password

Get Authenticated, Get the COOKIE ( Through Oracle IDM suite SOAP call)

Decrypt the COOKIE ( Through Oracle Enterprise business suite SOAP call)

and get the profile Info

Thats what happens now.

But there is a glitch in the decryption algorithm we currently have. And
when we decrypt + or some thing else comes with funny characters and does
not authenticate.

So I need to restrict them for now. When the algorithm gets corrected then I
will use standard RFC.

Keep in mind that ereg will disappear with PHP 6.  You might want to use

Re: [PHP] Regex validation

[VamVan]

Thank Guys,

I at least got part of it working , not the double words but almost
everything else than that:

function _email_validate($mail_address){
  $invalid_charset_pattern = "[(*+?)|~<>:;{}/ ]";
  if(ereg($invalid_charset_pattern, $mail_address)){
return false;
  }else{
return true;
  }
}

Thanks for the inputs

Good to know filter_var() exists in PHP5

Unless you have PHP5 you better validate the string in the way of checking
if it is fit's to your allowed characters and not checking if it contains
the NOT allowed charaters.

You better use: [a-z0-9A-Z\_\.]+ instead of [^\)\(\*\&[EMAIL PROTECTED] and I
haven't started yet with the weirdy ones

HTH,

I thought so at first, but it appears the final 3 array members of
INVALID_STRING are two characters wide. That could, of course, be
handled with a different algorithm from the other, one-character
members.

If your trying to filter E-Mail addresses, then filter_var is what you
should use:

http://php.net/filter_var

Based on what you've said, you might not need a regex, there may well
be an str* function that you can use. Maybe strpos().

Then you need to STFW and RTFM.  PHP uses Perl-style regexp's, by the way.

The best place to start, in my opinion, and a site you should
bookmark, is Jan Goyvaerts'[1] site.  He's done a fantastic job for
people of varying degrees of /regexpertise/:

http://www.regular-expressions.info ... that's how I learned. :)
Anyway... your match might be something like:

^/([^/\.]+)/?$

And the rewrite...

"/p.php?purl=$1"

To break it down, the match is looking for "The beginning of the line,
followed by a forward slash, followed by (begin capture group) 1 or more
characters that are not a forward slash or a period (end capture group)
followed by an optional forward slash, followed by the end of the line."

The rewrite is fairly straightforward.

I went 100% generic with the match due to your following e-mail that
stated "jasonpruim112" could be any username. If "112" is necessary for
the match, it would be more like:

^/([^/\.]+112)/?$

Hope this helps,
