[PHP] Regex for extracting quoted strings
Hi. I'm hoping someone can help me extract text between double quotes from a string. $regex = 'some magic'; $r = preg_match($regex, $sentence, $phrases); So, if $sentence = 'Dave said This is it. Nope, that is the wrong colour she replied.'; I want $phrases to contain 'This is it' and 'Nope, that is the wrong colour'. Can anyone help?

Thanks for explaining about the [^href]. I need to read up more about
greediness. I thought I understood it but guess not.
@Peter,
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
fragments inside the href. I couldn't figure out how to modify your

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 :
?php
$oTidy = new tidy();
$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
$links = array();
//Loop through each a tag in the dom and add it to the link array
foreach($xml-getElementsByTagName('a') as $link) {
$links[] = array('url' = $link-getAttribute('href'), 'text'
= $link-nodeValue);
}
//Return the links
return $links;
}
?

Yann

Re: [PHP] Regex pattern for preg_match_all
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 ) --- Simon Welsh Sent from my phone, excuse the brevity On 19/02/2011, at 10:36, Tommy Pham tommy...@gmail.com wrote: Hi folks, This is not directly relating to PHP but it's Friday so I'm gonna give it a shot :).

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:
%a\s+.*?(?!href)\s+href\s*=\s*([^\s\']+|\'[^\']+\'|\[^\]+\)[^]*(.*?)/a%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 a tag, non-greedy
* match with a closing /a tag

Re: [PHP] Regex pattern for preg_match_all
@Simon, Thanks for explaining about the [^href]. I need to read up more about greediness. I thought I understood it but guess not. @Peter, 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 fragments inside the href. I couldn't figure out how to modify your pattern to exclude the ', , and URL fragment from group 1 matches. Below is the new pattern with the new sample test cases that I got it to work. The new pattern failed only 1 of the non-compliant. $html = HTML a href=/sample/linkcontent/a a class=link href=/sample/link_extra_attribs title=sample linkcontent link_extra_attribs/a a href='/sample/link_single_quote'content link_single_quote/a a class='link' href='/sample/link_single_quote_pre_attribs'content link_single_quote_pre_attribs/a a class='link' href='/sample/link_single_quote_extra_attribs' title='sample link'content link_single_quote_extra_attribs/a a class='link' href='/sample/link_single_quote_extra_attribs_frag#fragment' title='sample link'content link_single_quote_extra_attribs_frag#fragment/a a class='link' href='/sample/link_single_quote_extra_attribs_query_frag?par=val#fragment' title='sample link'content link_single_quote_extra_attribs_query_frag?par=val#fragment/a a href=/sample/link_double_quotecontent link_double_quote/a a class=link href=/sample/link_double_quote_pre_attribscontent link_double_quote_pre_attribs/a a class=link href=/sample/link_double_quote_extra_attribs_frag#fragment title=sample linkcontent link_double_quote_extra_attribs_frag#fragment/a a class=link href=/sample/link_double_quote_extra_attribs_nested_tag title=sample linkimg class=image src=/images/content.jpg alt=content title=content link_double_quote_extra_attribs_nested_tag/a a href=#fragmentcontent fragment/a a class=link href=#fragment title=sample linkcontent fragment/a li class=small tab a class=y-mast-link images href=http://images.search.yahoo.com/images; data-b=http://www.yahoo.com;span class=tab-cover y-mast-bg-hide style=padding-left:0em;padding-right:0em;Images/span/a/li li class=small tab a class=y-mast-link video href=http://video.search.yahoo.com/video; data-b=http://www.yahoo.com;span class=tab-cover y-mast-bg-hide style=padding-left:0em;padding-right:0em;Video/span/a/li li class=small tab a class=y-mast-link local href=http://local.yahoo.com/results; data-b=http://www.yahoo.com;span class=tab-cover y-mast-bg-hide style=padding-left:0em;padding-right:0em;Local/span/a/li li class=small tab a class=y-mast-link shopping href=http://shopping.yahoo.com/search; data-b=http://www.yahoo.com;span class=tab-cover y-mast-bg-hide style=padding-left:0em;padding-right:0em;Shopping/span/a/li li class=small lasttab more-tab a class=y-mast-link more href=http://tools.search.yahoo.com/about/forsearchers.html; span class=tab-cover y-mast-bg-hideMore/spanspan class=y-fp-pg-controls arrow/span/a/li HTML; $pattern = '%a[\s]+[^]*?href\s*=\s*[\']?([^\'#]*)[\']?\s?[^]*(.*?)/a%ims'; preg_match_all($pattern, $html, $matches); Thanks for your time, Tommy -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Regex for ... genealogical names
A slightly more complex problem than phone numbers ... It is a sort of convention to use the format 'JohnDoeSMITH' or 'John Doe SMITH' where each forename starts with a capital and the surname is in upper case. I have a crude method of scanning for the capitals and splitting this to give me an array of name segments with [0] as the Surname and a variable number of Forenames, but is there an 'elegant' way via regex to extract this into an array? -- Lester Caine - G8HFL - Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk// Firebird - http://www.firebirdsql.org/index.php -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

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. Thanks, Ash http://www.ashleysheridan.co.uk

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.

Congrats. People in Hell would like ice water. Now we all know

Really, this isn't a PHP question, but rather one of regular
expressions. That said, something like this (untested) should work:
?php
$numbers = array(
'123-456-7890',
'2-654-06547',
'sf34-asdf-',
'abc-def-ghij',
'555_555_',
'000-000-',
'8007396325',
'241-555-2091',
'800-555-0129',
'900-976-739',
'5352-342=452',
'200-200-2000',
);
foreach ($numbers as $n) {
echo $n.(validate_phone($n) ? ' is ' : ' is not ').'a valid
US/Canadian telephone number.'.PHP_EOL;
}
function validate_phone($number) {
if
(preg_match('/^[2-9]{1,}[0-9]{2,}\-[2-9]{1,}[0-9]{2,}\-[0-9]{4,}$/',trim($number)))
{
return true;
}
return false;
}
?
THIS
is the regex you want to use... it is the most complete one that has
been posted here, and it works.

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}$

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.

Just keep in mind that invalid numbers will also pass that check,

more involved.

[PHP] Re: [PHP-DB] Re: [PHP] Regex for telephone numbers
Hi Ethan,
Could you do a string compare and check at certain characters for a
dash?
IE:
check the second character to see if it is a dash for 1-800...
if that is not a dash, check the fourth character for a dash, 469-9...
then the other places where dashes would be based on those two
characters.
You may have to investigate how international numbers would work and
adjust appropriately, but for the US, that should work.
Then just send an error message when it isn't like you want.

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.

You could also help them out a little with something like..
$phone = str_replace((, , $phone);
$phone = str_replace(), -, $phone);

Re: [PHP] Re: [PHP-DB] Re: [PHP] Regex for telephone numbers
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.

Congrats. People in Hell would like ice water. Now we all know
that everyone wants something. ;-P
Really, this isn't a PHP question, but rather one of regular
expressions. That said, something like this (untested) should work:
?php
$numbers = array(
'123-456-7890',
'2-654-06547',
'sf34-asdf-',
'abc-def-ghij',
'555_555_',
'000-000-',
'8007396325',
'241-555-2091',
'800-555-0129',
'900-976-739',
'5352-342=452',
'200-200-2000',
);
foreach ($numbers as $n) {
echo $n.(validate_phone($n) ? ' is ' : ' is not ').'a valid
US/Canadian telephone number.'.PHP_EOL;
}
function validate_phone($number) {
if
(preg_match('/^[2-9]{1,}[0-9]{2,}\-[2-9]{1,}[0-9]{2,}\-[0-9]{4,}$/',trim($number)))
{
return true;
}
return false;
}

[PHP] regex pattern for extracting URLs
I'm looking for a regular expression to accomplish a specific task.
I'm hoping someone who's really good at regex patterns can lend a quick hand.
I need a regex pattern that will grab URLs out of HTML that have a
certain link text. (i.e. the word Continue)
This is what I have so far but it does not work properly (If there are
other attributes in the a tag it returns them as part of the URL.)
preg_match_all('#a[\s]+[^]*href\s*=\s*([\\']+)([^]+?)(\1|)Continue/a#i',
$html, $matches);
It needs to be able to extract the URL and disregard arbitrary
attributes in the HTML tag
Test it with the following examples:
a href=/path/to/url.htmlContinue/a
a href='/path/to/url.html'Continue/a
a href=http://example.com/path/to/url.html; class=linkContinue/a
a style=font-size: 12px href=http://example.com/path/to/url.html;
onlick=someFunction('foo','bar')Continue/a
Please reply
Your help is much appreciated.
Thanks in advance,

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.

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.

[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

Re: [PHP] regex for multiple line breakes
You are replacing 1 or more matchs of a new line. To match 2 or more you can
use {2,}. It's a range, first number means min matches, second max matches.
Omitting last number means no max limit.
$data[txt] = preg_replace('`[\r\n]{2,}`',\n,$data[txt]);

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

Re: [PHP] regex for multiple line breakes
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

You are replacing 1 or more matchs of a new line. To match 2 or more you can use
{2,}. It's a range, first number means min matches, second max matches.
Omitting last number means no max limit.
$data[txt] = preg_replace('`[\r\n]{2,}`',\n,$data[txt]);

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
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.

[PHP] regex - filtering out chinese utf8 characters
Hi there,
I am trying to filter out content that is not ascii. Can I do this with
regex? For example:
$regex = '[AZ][09]';
if (preg_match($regex, $text)) {
return TRUE;
}
else {
return FALSE;
}
The reason I need to do this is that I am doing a mysql query with the
text and I need to make sure it is not UTF8. Otherwise I do get
following error:
Error: Illegal mix of collations (latin1_swedish_ci,IMPLICIT) and
(utf8_general_ci,COERCIBLE) for operation '='
I am new to regex and would be happy for a jump start to get this fixed.
Best regards, Merlin

Re: [PHP] regex - filtering out chinese utf8 characters
Hi Merlin,
I think the pattern you're looking for is '/[a-zA-Z0-9]/' which will
match all alphanumeric characters.

You prolly have already been here:
http://www.regular-expressions.info/
But if not, that site is certainly useful for all things regex.
Sorry I can't be of more help for your specific question.

Sad to say, same result. The second option looped an error: Warning: preg_replace(): Compilation failed: nothing to repeat at offset 17 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.

Jochem,
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.

RE: [PHP] Regex
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,
Jesse Hazen

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]+/
public function getSelection() {
$choice =
$this-validateChoice(trim(strtoupper(fgets(STDIN;
return $choice;
}
private function validateChoice($choice) {

[PHP] Regex help please
I'm normally OK with regex, especially if I fiddle with it long enough,
however I have fiddled with this one so long that I'm either totally
missing it or it's something simple. Does it have anything to do with
the backref, or the fact that the value of the backref has a $? I have:
$out = '
{$sites}
tr
td
{Site.id}
/td
/tr
{/$sites}';
And I want to capture the first {$tag}, everything in between and the
last {$/tag}. I have tried several things and here is my current regex
that looks like it should work, but doesn't:
preg_match_all('|{\$([^}]+)}(.+)({/\1})|Us', $out, $matches);
Gives:
Array
(
[0] = Array
(
)
[1] = Array
(
)
[2] = Array
(
)
[3] = Array
(
)
)

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}
tr
td
{Site.id}
/td
/tr
{/$sites}';
$matches = array();
preg_match_all('#{(\$[^}]+)}(.*?){(/\1)}#s', $out, $matches);
print_r($matches);
Produces this:
Array
(
[0] = Array
(
[0] = {$sites}
tr
td
{Site.id}
/td
/tr
{/$sites}
)
[1] = Array
(
[0] = $sites
)
[2] = Array
(
[0] =
tr
td
{Site.id}
/td
/tr
)
[3] = Array
(
[0] = /$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.

Hi,
Brand new to regex. So I have a cli which runs a regex on users input,

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 =

RE: [PHP] Regex
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,
Jesse Hazen

Re: [PHP] Regex
I have no idea about this control-Z thing, you might want to try it with UTF
(just add the 'u' modificator):
$str = preg_replace(#[^a-zA-Z0-9]+#uis, , $str);
Or try this:
$str = preg_replace(#(\b[^a-zA-Z0-9]\b?)+#uis, , $str);
I may be wrong about the second one but it might work...

RE: [PHP] Regex
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

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

I have no idea about this control-Z thing, you might want to try it with
UTF (just add the 'u' modificator):
$str = preg_replace(#[^a-zA-Z0-9]+#uis, , $str);
Or try this:
$str = preg_replace(#(\b[^a-zA-Z0-9]\b?)+#uis, , $str);
I may be wrong about the second one but it might work...

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.

Hello,

I have a REGEX that will find a function definition in a php file:

the problem is that:

2.a slash is NOT put in front of the parenthesis. Thats bad
3. If I try to escape the parenthesis with a \ , I get \\.
Help
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
Hi Behzad,
I would try a different approach ...
EXAMPLE (UTF-8):
!DOCTYPE html PUBLIC -//W3C//DTD XHTML 1.0 Transitional//EN
http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd;
html xmlns=http://www.w3.org/1999/xhtml;

?php
$username = '1aﺠﺟﺝﭻﭽﭼﭺ2b;
$encoding = 'utf-8';
$username = mbStringToArray($username, $encoding);
foreach($username as $char) {
if (strlen($char) == 1) echo $char.' is not a multibyte characterbr /';
}
function mbStringToArray ($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;
}
?

/html
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 ...

Re: [PHP] Regex validation
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:
?php
var_dump(imap_rfc822_parse_adrlist('! # $ % * + - / = ? ^ _ ` { |
} ~', ''));
?
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.

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.
