\w will match digits so \d isn't necessary, but it will also match
underscores which isn't desired.

You're correct, I forgot about the darn _ and \w includes digits

So, how's about this.

Try this. not tested.

$newName=preg_replace(%(?=[a-z])([A-Z]),  $1, $name);//Cap following low
case, add space before it

Next, alphas following a cap, lower case them

function lowCase($matches){return strtolower($matches[1]);}

$newName= preg_replace_callback(%(?=[A-Z])([A-Z])%, lowCase', $newName);

Sorry don't have time today to test; but, this should get you started.

Save and use the resultant $phoneNum; It is all that needs to be saved and used. 
Dashes, spaces and () are superfluous. Only the 10 digits are required for his 
application.

You've just used one any way:

 $phoneNum = preg_replace(%\D%, '', $phoneNum);//Remove everything except 
 digits 
 
 $phoneNum = ltrim($phoneNum,'1');//Remove leading 1s
 
 if(strlen($phoneValue) != 10)
  {
 throw new Exception(Phone number must be 10 digits, without leading a
 1. Check your entry carefull);
  }

One regex and two function calls when one regex would have sufficed?

Not entirely sure I understand.  You want to BOLD the things contained
in quotes and you put the * there to show that?  If so, this is not tested:

$bolded = preg_replace('#([\'])(.*?)\1#', 'b\1\2\1/b', $text);

That's not going to happen without some other criteria.  There is no way
for the regex engine to guess at which sets of quotes belong inside
another set of quotes.

RewriteRule ^directory/(.*)$ /newdirectory/$1 [L]

the other alternative is to let php handle it..
this is basicaly if request isn't a file or a directory route to a php

RewriteCond %{REQUEST_FILENAME} !-f

RewriteRule ^jasonpruim112$ /p.php?purl=jasonpruim112 [L]

Just tried it, and it pops up with a 404... I'll keep looking.
One other thing that I should probably add is the fact that the 
^jasonpruim112$ could have hundreds of counterparts ^bobsmith112$ 
^jerrybob112$ etc... etc...

here's a typical rule; probably best to modify what works and go from 
there :)


RewriteRule ^directory/(.*)$ /newdirectory/$1 [L]

the other alternative is to let php handle it..
this is basicaly if request isn't a file or a directory route to a php 
handler [my prefered way]:


RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /notfound_handler.php [L]


RewriteRule . /notfound_handler.php [L,QSA]

the QSA tells apache to to automatically append any query string, saves
the hassle of having to deal with it in the regexp (assuming you might need it)

also beware that external redirects will cause POSTs to become GETs so that
the script/code in question never recieves the POST.



Interesting idea... I hadn't thought about that... Then I could just use 
a regex in php and grab everything after the domain name and pass it to 
my database to search and find the appropriate info to pull out...


your probably wanting the info in $_SERVER['REQUEST_URI'] ... which is
the complete uri before it was rewritten.

also check this func out, will probably spare you the regexp completely:

http://php.net/manual/en/function.parse-url.php



I'll have to do some searching :)

That regex might not always work for you, (amp;) comes to mind.  You

[PHP] Re: Regex for Advanced search feature

[Al]

Go here and get charprobe http://www.dextronet.com/charprobe.php  It's a super 
utility to have.


Look up the hex code for a space, /x20 as I recall.

Then pick a non-printable code that you like e.g., /x83 or a printable one that 
users cannot enter.


Then simply preg_replace(%/x20+%, /83, $string);//one or more spaces

If you want to preserve the number of spaces don't use +.


Kevin Murphy wrote:
I'm trying to create an advanced search feature for my site, and I have 
it mostly working the way I want. I take whatever search term 
($searchkey) that the user submits, explodes if off any spaces between 
words, and then use that to search for each word separately.


$keys = explode( ,$searchkey);

So the search phrase of:

Dog Cat Horse

would output :

Array
(
[0] = Dog
[1] = Cat
[2] = Horse
)

However, I would like to add the ability to have phrases in there 
indicated by  marks. So, if the search phrase was this:


Dog Cat Horse

It would output:

Array
(
[0] = Dog Cat
[1] = Horse
)

My concept to solve this is right before I explode the keys as above, to 
replace any spaces within  marks with a garbage string of characters 
(say XX) using a regular expression, and then later replace it 
back with a space. However, I suck at regular expressions and can't 
figure it out.


Anyone have a way for me to accomplish this with a regular expression or 
with another method?

line 81


I still would like to know what it means but
I solved the script problem.
I found that since  $groups is a string  that was exploded to form the 
$g_list array
it may have been struggling to try and crawl back through the whole 
string in the
middle of the for loop. But I don't know, because I don't know what 
REG_ERANGE means.
I should have not been trying to run this regex at this stage of the 
script and, in
fact (I have been doing a lot of complex programming on this project ) 
I had
the same regex further down the list where is should have been and was 
already.
Anyhow, I think this may be valuable for anyone who is trying to learn

If you didn't get it, here it is again.

You used to have the - after the 9 at the end, and then you
tacked on the \. and \/ after that, and now PCRE is trying to
use the - as if it were a range-specifier, like, a-z or 0-9,
only you've got, essentially, a-z0-9-.

How's this:

?php
// $s contains the entry from the table.

// Non-strict url matching.
$s = preg_replace('/(http:\/\/[^\s]+)/i', A href=\$1\$1/A, $s);
?

This is very non strict. Anything starting with http:// until the next
whitespace (\s) is clickable. You might want to put a more strict rule in
there, but it depends on the text your searching in. Note that above code
does not work when an url is at the end of a line, and followed by a
period (.).

[PHP] Re: Regex

[Alex Turner]

If what you mean is a db table, then it would seem to me that you should 
not be using a regex.  PHP has rawurlencode() for this sort of thing.


But - you should learn regex ;-)

Try something like (untested and late at night)

function urlme($location)
{
$enc=rawurlencode($location);
$spc=htmlspecialchars($location);
return A href='http://$enc'$spc/a;
}

If I'm understanding what you want, consider this.  I use it to check matching 
tags.

First get an array of all the start tags:

$pattern= %([^/][a-z_\-]*)%i;   //all start tags used xxx

preg_match_all($pattern, $text_str, $matches);

$start_tags= $matches[1];

$start_tag_nums= array_count_values($start_tags);   //get count for each tag

Then do the same for your end tags, using the same pattern but with the end tag 
slash. /

Finally, you make a text list of the mismatches:

foreach($start_tag_nums as $tag= $num){

if($num != $end_tag_nums[$tag]) $end_error_msg .= lt;$taggt; || ;

}//end foreach

echo $end_error_msg;

For what it's worth..

I'm moderately good with regex; but, I wouldn't even try to get an expression like yours to work properly, with all 
possiblities and exceptions.


Suggest breaking it up into several separate tests.

I don't know if these are equal.
What about \r\n line endings?
And what about \r line endings (from old Macs)?
I guess file() handles all of these cases (didn't test it though)
and your code doesn't (with \r you'll get a one line file!).

I have the following regex /Tel:\s*(.[^A-z:]+)/ and
/Fax:\s*(.[^A-z:]+)/ all these work as expected and stop just before
the next Tag. However I run into hassels  around the TAGINCAPS as the
response after it is all in caps and i cant get the Regex to stop just
before the next tag: which may be either all caps or lowercase.

I cant seem to find the regex that will retreive all chartures just
before a word with a :  regalrdless of case.

I have played around with the regex coach but still seem to be comming
up short so i thought i would see if anybody can see anything i might

any help most appreciated.

Add and i for case insensitive for all except the numbers type e.g.,

[PHP] RE: regex question

[Carl Furst]

I think there maybe a few ways to do this... One is

[EMAIL PROTECTED]@[EMAIL PROTECTED]

That basically says find me the pattern where one non-at symbol is followed
by an at symbol followed by another non-at symbol

So if you do 

?php

$string = @ one more T@@me for @ and i@ the Bl@@dy [EMAIL PROTECTED];


$pattern = '/[EMAIL PROTECTED](@)[EMAIL PROTECTED]/';

$numMatch = preg_match_all($pattern, $string, $matches);

echo numMatch: $numMatch\n;
print_r ($matches);

?

numMatch: 3
Array
(
[0] = Array
(
[0] =  @ 
[1] = i@ 
[2] = [EMAIL PROTECTED]
)

[1] = Array
(
[0] = @
[1] = @
[2] = @
)

)

Well, where that fails is when you have @'s at the beginning or end of the
string and that's easy enough to do.. So that would mean three searches...
There's probably a way to integrate them into one without loosing integrity,
but it depends on what kind of regexp libs you have, I reckon. It also
depends on what you really are trying to do with this search. Consider
str_replace, strpos and strtr as well.

Thanks,


Carl

I only want the two occurrences with a single occurrence of @.

U means it'll become UNgreedy (means it ends at the first occurence 
instead of the last),
m means multiline, so . also matches \n and \r chars.
i means it's case-INsensitive. Which I thought was just useful ;)

print_r($matches) will show what comes out exactly how. Then at some 
point you'll probably be able to echo something like echo 
'###LEVEL'.$matches[1][$i].'###';
where $i would be the part you're echoing from.

Anyway, it'll be SOMETHING like that. I tend to always print_r the 
results first, and then write more code based on the result.

 Hi,
 I am just starting out with regex (and classes) so am
 not sure how to do this...

 I am seeing if a HTML file exists, if yes, I am using
 file_get_contents to get the entire HTML file into a
 string.

 In the HTML file I already have this:

 !-- Start header --
 html
 body
 whatever you want comes here
 !-- End header --

 How do I use a regex to span these multiple lines and
 simply cut everything (including the start..end
 part)from !-- Start header -- to !-- End header --

 Second question:
 I am using file_get_contents, is it better to use this
 than file() or fread() ?

 Thanks,
 Mag

Hi,

I can't answer your regexp question but some thoughts on file() etc.:
- file() returns the contents line by line as an array, so this makes only
sense if you need the contents in this form, e.g. for looping through each
line and applying a function or whatever
- fread() requires a file handle that you have to create with fopen(), so
file_get_contents() is kind of a shortcut for fopen()/fread()

Hope this helps.

I am the very lowest of newbies when it comes to regex

#h[1-9](.*)/h[1-9]#Uie
`h([1-6]).*?/h\1)`sie
What is the purpose of the back-ticks and the '#'? 
PCRE patterns has to be enclosed, you can use all the non alpha numerics 
characters to do that. Personnaly, I prefer back ticks because I don't 
have to escape it often inside my patterns.
For my example, you can also remove the ``s pattern modifier, It makes 
the dot ( . ) accept any New line characters, and I had not see  that 
you removed them before.

What are 'Uie' and  'sie'?
there are patterns modifiers, you can find a complete list and 
descriptions here :

I have removed all the NL and CR chars from the string
I am matching to make things easier.  Also, I have run
tidy on the code so the tags are all uniform.
The above string seems to match the tag well now, but
I still need to remove the br tags from the tag
contents (.*).
To remove the br / tags, you need to call preg_replace_callback() :
?php
$str = 'h1hi br / ../h1 bla bla h5  br / ../h5 ...br /';
function cbk_br($match) {
	return 'h' . $match[1] . '' . str_replace('br /', '', $match[2]) . 
'/h' . $match[1] . '';
}
$return = preg_replace_callback('`h([1-6])(.*?)/h\1`si', 'cbk_br', 
$str);
echo $return;
?

The strings I will be matching are html formatted
text.  Sample h* tags with content are below:
h4Ex-Secretary Mickey Mouse br /Loses Mass.
Primary/h4
h4Ex-Secretary Mickey Mouse br /Loses Mass.
Primary br / Wins New Jersey/h4
h4Ex-Secretary Reich Loses Mass. Primary/h4
Again, any help is appreciated.

RE: [PHP] Re: regex help needed -- Solved! Thanks!

[Kathleen Ballard]

Thanks!  Works like a charm!

I am the very lowest of newbies when it comes to regex
and working through your solutions has been very
educational.  I have one question about something I
couldn't figure out: 

#h[1-9](.*)/h[1-9]#Uie
`h([1-6]).*?/h\1)`sie
What is the purpose of the back-ticks and the '#'? 
What are 'Uie' and  'sie'?

Thanks again!

First, the short version. You can fix this by using backreferences:
 $string = preg_replace(/([^\r])\n/i, \\1\r\n, $string);
Now, the reason:
preg_replace() replaces everything which matched, so both the \n and
the character before it will be replaced (as they both had to match
to make the pattern match).
Luckily, preg_replace() stores a list of matches, which you can use
either later in the same pattern or in the replace string. This is
called a 'backreference'. You can tell preg_replace() which part(s) of
the pattern you want to store in this fashion by enclosing those parts
in parentheses.
In your case, you want to store the character before the \n which matched,
so you would enclose it in parentheses like so: /([^\r])\n/i. Thereafter
you can refer to that portion of the pattern match with the sequence \1.
If you add another set of parens, you would refer to it with \2...and so
on. You can even nest pattern matches like this, in which case they are
counted by the opening paren. So the replacement string would then become
\\1\r\n. (You need the extra \ in front of \1 to prevent PHP's string
interpolation parsing the \1 before it gets passed to preg_replace()).

 Check the PHP manual for preg_match()
 (http://us3.php.net/manual/en/function.preg-match.php).

 I did play around with it a little bit, and I think I've got a starting
 point for you to work with.  Try out this code and then play around with
 it to get the results you need.  $matches[2][0] will hold the full line
 for Mayberry Mob.  You could then just use the substr() function to pull
 the data from that line.

 The code is, as follows:

 $subject =

Re: [PHP] Re: Regex Help

[Ben Ramsey]

Why do you need to remove the delimeters?  If you remove them, then it 
makes it quite difficult to get the data you need.  If you want to 
display the date and race type without the square brackets around them, 
then use $matches[0][1] and $matches[1][1] instead of $matches[0][0] or 
$matches[1][0].

Try this:
$pattern = '#function
(\w+)\(((?:\$\w+(?:,\s*\$\w+)*?)|\s*)\)\s*\{[.\s]*((?:return\s+[^;]*\s*;)|)[
.\s]*#m';

Notice that \w means:
A word character is any letter or digit or the underscore character, that
is, any character which can be part of a Perl word.

Though, any regexp for this task can be easily fooled; i.e: there's no
regexp for all cases; PHP's language cannot be described properly using just
a regular expression.

My regex skills are serious lacking and after scouring the net for
relevant links I'm a bit stuck.  I've got a textarea field where I pull
user input from, and I'd like to search this entire field for a Windows

Basically my users are allowed to specify HTML img tags in this textarea
and I'd like to make sure that they don't reference any images that are on
their local hard drive (which many of them are doing and then thinking
the HTML that I generate from that actually works when it doesn't).
Suggestions?

hi,

i would start like this:

1. get the entire src-param of your img tag:

?php
$regex = '/src=([^])/';
?
this should search for everything between the two doubleqoutes and give 
it as $match[1] if working with this param in preg_match().

2. check this string for url or local path:

some possibilities are, to check for backslashes, as they are only 
allowed in win-paths, not in url. or to check whether your path starts 
with a letter, followed by a colon ('/[a-zA-Z]:/') as the local root 
(drive letter). if both is false assume that it's a relative or absolute 
url.
the other (better?) way is, to check generally, whether it's a valid url 
according to rfc1738 (a local win-path isn't). maybe there are existing 
functions?

Incidentally the procedure for correcting the number is flawed. If you

a 1 then the required additional 1 will never be prepended. Really what
you want is if the sequence of numbers is 9 digits long then precede
with a 1.

[PHP] Re: regex problem

[Merlin]

ufff.. sorry guys, but I have to explain that better. I appreciate your
help, maybe I did not give enough info.

I am trying to redirect with apache modrewrite. To do this you have to use
regex (not if functions:-)

My problem is, that there are member accounts which look like that:

membername/contact.html

and there are partner accounts which look like this:

partner/name/contact.html

The goal is to redirect only if it is a member account. If I put a
(.*)/contact.html it also matches the partner/
I tryed putting a root / infront, but there is not / root for the url from
apaches point of view.

So I would need a regex which will match the member account, but if the
first word is partner it should
not terminate.

This seems to be a tough one!

Thanx for any help,

Mod rewrite is a powerful tool and you can accomplish what you are
doing several different ways.  As you can tell most people have
been giving attempts to fix your problem without success. This is
because it is not entirely clear what you need done.

RE: [PHP] Re: regex problem

[Wouter van Vliet]

So, what you want is to pretty much use this regex

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

when matched on this URI, the backreferences will contain

\\1 partner/
\\2 name
\\3 contact.html
\\4 .html

  partner/name/contact.html

I have not tested it, but I just guess it will work ;) Wanna know why? I'll
tell you :D

- It first looks at the beginning of the string and will go on untill a the
next pair of () start (partner/)
- That happens there where there is a string containing any character, but
not a slash (partner)
- as a seperator another slash is added
- it starts to match the last part of the url and looks up untill the end.
Again a string containing no slashes

Hope it does do what I expect it to do .. ;)

Wouter

[PHP] Re: Regex help needed

[Nomadeous]

First, the prob you got : WARNING 
comes from the following error:
(\s+face=\Verdana, Arial, Helvetica, sans-serif\|)
After the | (OR) sign, you must define another case, example:
echo eregi_replace (tr bgcolor=\#F8F8F1\(\s*)td\s*font 
size=\2\(\s+face=\Verdana, Arial, Helvetica, 
sans-serif\|\s)\s*purchasing power parity, '%POWER%', 
'tdtrsdsdsstr bgcolor=#f8f8f1 face=Verdana, Arial, Helvetica, 
sans-seriftdfont size=2Purchasing power parity');

Secondly, it's right that the \s expression is not recognised in
 purchasing\s+power\s+parity  , a little strange, but you can use two 
different ways instead of '\s':
 - [[:space:]]
 - [ ]
The brackets allows you to define a sequence of characters patterns (in 
the second case above, the space character).
It will give:
echo eregi_replace (tr bgcolor=\#F8F8F1\(\s*)td\s*font 
size=\2\\s*purchasing[[:space:]]+power[[:space:]]+parity, '%POWER%', 
'tdtrsdsdsstr bgcolor=#f8f8f1tdfont size=2Purchasing power 
parity');

Just a little help, you can find on the page 
http://www.php.net/manual/en/ref.regex.php that could be useful for you:

^ Start of line
$ End of line
n? Zero or only one single occurrence of character 'n'
n* Zero or more occurrences of character 'n'
n+ At least one or more occurrences of character 'n'
n{2} Exactly two occurrences of 'n'
n{2,} At least 2 or more occurrences of 'n'
n{2,4} From 2 to 4 occurrences of 'n'
. Any single character
() Parenthesis to group expressions
(.*) Zero or more occurrences of any single character, ie, anything!
(n|a) Either 'n' or 'a'
[1-6] Any single digit in the range between 1 and 6
[c-h] Any single lower case letter in the range between c and h
[D-M] Any single upper case letter in the range between D and M
[^a-z] Any single character EXCEPT any lower case letter between a and z.
Pitfall: the ^ symbol only acts as an EXCEPT rule if it is the
very first character inside a range, and it denies the
entire range including the ^ symbol itself if it appears again
later in the range. Also remember that if it is the first
character in the entire expression, it means start of line.
In any other place, it is always treated as a regular ^ symbol.
In other words, you cannot deny a word with ^undesired_word
or a group with ^(undesired_phrase).
Read more detailed regex documentation to find out what is
necessary to achieve this.
[_4^a-zA-Z] Any single character which can be the underscore or the
number 4 or the ^ symbol or any letter, lower or upper case
?, +, * and the {} count parameters can be appended not only to a single 
character, but also to a group() or a range[].

therefore,
^.{2}[a-z]{1,2}_?[0-9]*([1-6]|[a-f])[^1-9]{2}a+$
would mean:
^.{2} = A line beginning with any two characters,
[a-z]{1,2} = followed by either 1 or 2 lower case letters,
_? = followed by an optional underscore,
[0-9]* = followed by zero or more digits,
([1-6]|[a-f]) = followed by either a digit between 1 and 6 OR a
lower case letter between a and f,
[^1-9]{2} = followed by any two characters except digits
between 1 and 9 (0 is possible),
a+$ = followed by at least one or more
occurrences of 'a' at the end of a line.

Hello,

For example I tried
echo eregi_replace (tr bgcolor=\#F8F8F1\(\s*)td\s*font 
size=\2\\s*purchasing power parity, '%POWER%', 'tdtrsdsdsstr

size=\2\\s*purchasing\s+power\s+parity, '%POWER%', 
'tdtrsdsdsstr bgcolor=#f8f8f1tdfont size=2Purchasing power

It does not detect the string. Srange. According to what I know, \s+ 
will detect a single space also. I tried chnaging the last 2 \s+ to \s* 
but this did not work also.
Any ideas on this one?

As I proceed I would like the expression to detect the optional face 
attribute also, so I tried
echo eregi_replace (tr bgcolor=\#F8F8F1\(\s*)td\s*font 
size=\2\(\s+face=\Verdana, Arial, Helvetica,

... and this gave me an error like

Any ideas? BTW any place where I can get started on regex? I got a perl

did i understand you correct? you search in real html-code (with '' and

- if so, your regex can't find any gt;. either you search for an '' or you
use htmlspecialchars() or htmlentities() to convert these brackets before.
- also, if in your href= stands a full url (with
scheme://domain.tld) your '\w' doesn't work
- what are the optonal escaped slashes for? '\/?'

hope this helps for your start:
$body = 'a href=http://www.url;';
$body = preg_replace ('/()(a href=[^]+)()/', 'lt;\\2

 If you want the entire string to be tested for digits, you 
 need to add the
 length of the string to the regex pattern:
 
 $length = strlen($data);
 preg_match([0-9]{$length}, $data);

Or anchor the pattern to both start and end of the string:

  preg_match(^[0-9]+$, $data);

I don't understand what it is you're trying to accomplish, so, it's hard to
offer a solution. If you just want to verify whether or not a variable
contains numeric data, why not just use the is_numeric() function:

http://us4.php.net/manual/en/function.is-numeric.php

preg_match() will return TRUE if it finds the pattern ANYWHERE in the
string, so, that's why asdf789 passes the test because it contains digits,
whereas 'asdf' won't pass the test because the numbers 0-9 can't be found
anywhere in that string.

If you want the entire string to be tested for digits, you need to add the
length of the string to the regex pattern:

$length = strlen($data);
preg_match([0-9]{$length}, $data);

 Subject: regex problem
 
 Hello,,
 
 I have a preg_match issue matching numbers.  I am currently using
 
 !preg_match ('/([0-9\-\.\#:])/', $_POST['nums1']
 throw error[]
 
 This fails if you use something like ' asdf ' but if you use ' asdf789 ' it
 passes false and does not throw an error.
 This is not the obvious solution  I know its a problem in my regular
 expression.  Should I ONLY be using
 
 ' /([0-9])/ ' ,  ?
 
 Thanks in advance.
 Daniel

 I'm using the following to try and replace urls in my html output:

 $newhrefs = preg_replace(/script.php\?(.*)=(.*)(.*)=(.*)(.*)=(.*)/,
 script-$1-$2-$3-$4-$5-$6.html, $hrefs);

 This works fine as long as there are exactly 3 var=val pairs... not 1 or 2
 or 4 or more...

 How can I write my expression to match 1 or more pairs???  For example:

 script.php?var=val
 script.php?var=valvar2=val2
 script.php?var=valvar2=val2var3=val3
 etc...etc...etc...

 TIA,
 Shawn

 i have to check if there's a dot in a string, and i need nothing but the

You can escape the dot either by putting a backslash in front of it or
putting it inside square brackets.  So:

ereg(a.b,aaabbb);

is true, but

ereg(a[.]b,aaabbb);

is false.  Other sensitive characters can also be escaped in this way;
the bracket expression [][.^$()|*+?-] matches any of those characters.
And to match any *except* those characters, use [^][.^$()|*+?-].

Check the re_format(7) man page for details.  If you don't have a unix
box handy, check http://www.freebsd.org/cgi/man.cgi?query=re_format .

 How would take a regular non-formatted text link (http://www.link.com) and

 Darn, Outlook formats it, but you get the idea.  It would just be typed out
 normally.

How about:

$href=(https?://([a-z0-9]+\.)+[a-z][a-z]+/[a-z0-9_./~%-]*);
$repl=a href='\\1'\\1/a;
$line=eregi_replace($href, $repl, $line);

You can of course make $href less restrictive if you're liberal minded
about your URL formats.

 I'm looking for a regex which splits a string by commas, but only if the

Well, as it happens I'm too lazy to write it for you :-)

?php

$str = 'hi bmy friend/b! br / this message uses html entities a 
href=http://www.trini0.org;test/a!';
$str = preg_replace('/(a href=http:\/\/.*.*\/a)/', 
htmlspecialchars($1), $str);

Maybe I'm missing something here, but can't you just do:

$str = htmlspecialchars($str);
