Re: [PHP] Anyone for cookies and milk? :-)
>From the official doc:
http://www.php.net/manual/en/function.setcookie.php
All the arguments except the name argument are optional. You may also
replace an argument with an empty string ("") in order to skip that
argument. Because the expire and secure arguments are integers, they cannot
be skipped with an empty string, use a zero (0) instead.
setcookie("name2","1",0,"",".bestwebhosters.com");
or
setcookie("name2","1",0,"",".bestwebhosters.com",0); ;-)

Those errors appear because you out "" in the third parameter of the
setcookie function.
The parser expects a long (or an integer if you prefer ;-) )
This parameter is used to affect the life of the cookie, put 215000, for a
one hour cookie.
Thanks for the milk :-)

[PHP] Re: MySQL query problems
But what's your prob ?
When you say the second one seems to never be executed ...
Does the line:
$row = mysql_fetch_array($result2);
launches a Php Error ?
And pay attention, because you're using mysql_fetch_array and
mysql_fetch_row, be sure that
you are not treating the result in the same way ;-)

[PHP] Re: Regex help needed
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 ("(\s*)\s*\s*purchasing power parity", '%POWER%',
'sdsdssPurchasing 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 ("(\s*)\s*\s*purchasing[[:space:]]+power[[:space:]]+parity", '%POWER%',
'sdsdssPurchasing 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,
Well I am doing by first reg ex operations and I am having problems
which I just cannot figure out.
For example I tried
echo eregi_replace ("(\s*)\s*\s*purchasing power parity", '%POWER%', 'sdsdssPurchasing power parity');
and this worked perfectly,
but when I chnaged that to
echo eregi_replace ("(\s*)\s*\s*purchasing\s+power\s+parity", '%POWER%',
'sdsdssPurchasing power
parity');
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 ("(\s*)\s*\s*purchasing power parity", '%POWER%',
'sdsdssPurchasing power parity');
... and this gave me an error like
Warning: eregi_replace(): REG_EMPTY:çempty (sub)expression in
D:\sid\dg\test.php on line 2
Any ideas? BTW any place where I can get started on regex? I got a perl
book that explains regex, but I have got to learn perl first (I dont
know any perl)
Thanks in advance.

I think, you Forgot, a \ before the $ at the end of the expression...
that should work.
Unfortunately it doesn't for some reason. Don't know why.
but you could do this:
$pattern = "/^[a-z0-9\-_\.]+\.[a-z0-9]{$foo, $bar}\$/";
preg_match($pattern, $some_string)
But this does, so Im good. Thanks for the tips...
