Re: [PHP-DB] Google Style Search Results
Sure,
Firstly, thank you for the credit, that was only my second mid-scale project,
coded ground up in Textpad 4 ;-)
enough patting my own back, onto business..
http://aries.the-spectrum.org/webdev/wawd/forums/search.php?q=sufficient%2Blargest=postsb%5B%5D=*maxres=25ob=datetimeot=DESC
Notice some changes??
You've just sparked a interest in me to revise and rewrite some of the code for
that page this lovely 33 degree celcius summer Friday afternoon here in
Australia.. :-)
Previously, it was only really just pumping out the first sentence or so of
text from the matched query..
Now though it is actually going through each query word and matching a set
number of words surrounding it [in this case I've made it five] and throwing
that out in the extraction field... with each of these said matches being
seperated by a ellipsis [...]
All I did was conjure up a regular expression that basically just matches words
:-) haha ironically..
Here it is:
$extract_result=;
preg_match_all(/((?:[\w]+ ?){0,5})[\w
\.\,\-\;]((?:.join(|,$q_arr).))([\w]*)[\w \.\,\-\;]((?:[\w]+
?){0,5})/i,$row[content],$ext_matches,PREG_SET_ORDER);
foreach($ext_matches as $ext_arr) {
$extract_result .= $ext_arr[1]. B.$ext_arr[2]./B.$ext_arr[3].
.$ext_arr[4]. ... ;
}
Are you familiar with regex?
It really shouldn't be hard to implement a similiar concept with whatever your
current search system does.. My system as can be seen from this above code
actually breaks up the query string sent via the form on search page into each
word.. therefore you have an array [$q_arr] that looks like Array(
sufficient, large) ..
Hence in that regex above i just did a join using the | pipe symbol.. I use
this so when it joins all the words together they come out as: word1|word2|word3
meaning regex will match 5 or less words before and after any of the given
words. the | symbol means bitwise OR, for example:
run(ning|ner)
will match running or runner but not runs
Sorry if you already know some of this I am just trying to make sure I explain
myself fully as I am unawares as to your experience level.
Anyway, so yes I simply use the handy preg_match_all function which will run
this regex statement upon the entire $row[content] which in my case is just
the entire content of the post which it found to match words in.. and from that
it simply matches these certain given keywords and their surrounding word/s..
I then use a foreach structure to simply iterate over each of the matches and
create the lovely string you see before you, it does this simply by reprinting
the original matched string, creating a B/B bold effect on the given search
word and adding an ellipsis at the end for simple athestic reasons..
If you want any more examples or clarification please feel free to ask..
Enjoy ;-)

Great site, Julien! Probably more involved than we need for our project,
but very, very impressive. I really like the CSS styling in particular. If
you could tell me how you are displaying the content within the extract

[PHP-DB] inserting data into Oracle tables
Is there a standard for inserting data into Oracle tables from a user input field in PHP? Most Oracle tables will have a limit on the amount characters such as Name VARCHAR2(60 BYTE) - this means the maximum amount of characters allowed is 60. If you use special characters in PHP such as entering the following into a input box ¬!£$%^*()[EMAIL PROTECTED]?|\,./;'#][=-¦abcdefghijklmnopqrstuvwxyzA When this gets passed to Oracle it takes the overall characters in the insert statement to 64, which then fails because it is over the Oracle table limit. Is there a standard way of dealing with something like this.

Re: [PHP-DB] Manipulating text
Quite right.. BU: and I quote: $variable = play_time; how may I remove play_ from $variable and just have $variable equal to time? To me, that is asking to strip or remove the string play_ from the string play_time Am I wrong? Especially when reinforced with and just have the $variable equal to 'time'?

Re: [PHP-DB] Google Style Search Results
Yay, Questionnaire time
I love this part of the game
a) I'm not very familiar with regex at all and was wondering if you could
tell me how your regex would handle two matched search strings that
exist within a few words of each other in the text. For example A
larger server would be sufficient I think.
Answer: As I think I may have mentioned All I did was conjure up a regular
expression
True, I didn't imply I wrote that regex in under 32 seconds...But I'm sure I
was trying to come across with the fact that with improvement it could be
much more powerful.
Like this example:
http://aries.the-spectrum.org/webdev/wawd/forums/search.php?q=were%2Baddst=postsb%5B%5D=*maxres=25ob=datetimeot=DESC
Is that better??
multiple words within the same piece of string..
Again, much much much more work can be done, this was a very quick stub
example to show the flexibility of regex..
Now a new issue that has been presented is if you DO have multiple words
close together it will only grab x amount of words to the before and after
that central word, including perhaps another keyword.. as you can see on
above link..
Again, give me another 3 minutes in the code and I'm sure I'll work that one
too..
b)Also in the link you provided (reproduced below) the first matched
word is surrounded by 4 words and the second by 5 words, is there a
reason for this?
Answer: Ooh this is my favourite :-) Yes, great reason why when you conduct
a search such as this:
http://aries.the-spectrum.org/webdev/wawd/forums/search.php?q=sufficient%2Blargest=postsb%5B%5D=*maxres=25ob=datetimeot=DESC
You received the 4 word and 5 word output.. Why don't you head over to the
link that is generated on that search result entry??
Look around at the actual content of that forum entry and you will soon see
that the first match occurs on a line that physically only has 9 words,
therefore it can only really match what exists.
Good point though, for a split second I actually thought to myself there
might be something wrong, but as usual and until I'm proved wrong; I'm right
again. PHP and REGEX have never failed me.
I'm sure you all are well aware already of the saying that describes how
there is no such thing as computer errors, only stupid humans.
And that is precisely it, I have been and still am a stupid human, and I
will usually sit there for quite a while reloading and running a regex in my
head to ensure it runs and parses as it should.
Simple ones like this don't take too much planning, but they can get hairy
:-)
Hopefully that answers your queries Graham..
Kindest Regards to everybody!

Re: [PHP-DB] Google Style Search Results
Thats ok, sorry to have come across a bit 'narky' in that response by the way I was just under some pressure at the time, I should really compose myself more before trying to lend a hand or some advice and head to the deep end in my ramblings.. haha There really isn't much to Regex to be honest, whilst some patterns can look awfully complicated, and I will admit, generally you can't really neaten up long patterns as it just looks unreadable after wards.. For example: // Parse input string via forum URL substitution method.. $parsedBodyStr = preg_replace(/\[URL(?:\=*([^\]]*))\]([^\[]*)\[\/URL\]/sie,'A HREF=\'.forumFormatPostURL(\$2\).'\ TARGET=_BLANK'.(strlen(\$1\) 0 ? \$1\ : \$2\).'/A',$parsedBodyStr); It is simply a line that is designed to convert custom forum embedded hyperlink anchors into functional HTML standard anchors.. Whilst somewhat ugly to look at, it works 100% everytime. see my forum, like many other similiar class PHP forums, only allows url's to be entered via some custom structure: [url]http://the-spectrum.org[/url] and as a small feature I also add the title parameter, [url=The Religion of Gurus!]http://php.net[/url] These would be respectively entered in the code when someone views that forum page and its messages as: http://the-spectrum.org and The Religion of Gurus! Now, trying to neaten that: // Parse input string via forum URL substitution method.. $parsedBodyStr = preg_replace( /\[URL(?:\=*([^\]]*))\]([^\[]*)\[\/URL\]/sie, 'A HREF=\'.forumFormatPostURL(\$2\).'\ TARGET=_BLANK'.(strlen(\$1\) 0 ? \$1\ : \$2\).'/A', $parsedBodyStr ); Not much of an improvement.. Unfortunately you can't really go about entering spaces and so forth in your patterns otherwise it will render them unfunctional. You can go around it different ways.. I neaten my code and enhance reusability by simply conquering a particular pattern, and then that is just placed in a global $SYSTEM[REGEX_FILTER] array which I can access later on in a shorthand version, keeps code legible Particular if you are going to be using either a lot of patterns or even using one single pattern very often, Remember this does nothing for perfomance, purely asthetics only.. The easiest way to learn, just as I learnt mastering php, mysql, apache2 and picking up unix/bsd, c++, object pascal, and the list goes on.. Is to teach yourself.. I never paid a cent to learn php/mysql, never went to a single tutor/lecture/seminar etc.. Just hop on the net, you'll find tonnes of resources if you want examples, or better yet, invent a problem you want to solve with some kind of manipulation with a string, and try to code a pattern for it.. I guarantee you there will be a pattern for virtually any problem you could imagine needing a fix for.. I have never encountered a problem yet where a regex pattern can't pull me out of trouble Believe this or not, but I learnt the basics of regex patterns in Perl, but it wasn't till I hit the PHP PCRE [Perl-Compliant Reg Exp] references which refer to the pattern modifiers and syntax that I really picked up on it.. That syntax guide along with the modifier page are excellent to start working off.. Very specific, short examples given for many different aspects.. I personally love it anyway..

who knows ajax , I want to make a website use ajax technolgy.
thanks,everybody!

Sure,
Firstly, thank you for the credit, that was only my second mid-scale project,
coded ground up in Textpad 4 ;-)
enough patting my own back, onto business..
http://aries.the-spectrum.org/webdev/wawd/forums/search.php?q=sufficient%2Blargest=postsb%5B%5D=*maxres=25ob=datetimeot=DESC
Notice some changes??
You've just sparked a interest in me to revise and rewrite some of the code
for that page this lovely 33 degree celcius summer Friday afternoon here in
Australia.. :-)
Previously, it was only really just pumping out the first sentence or so of
text from the matched query..
Now though it is actually going through each query word and matching a set
number of words surrounding it [in this case I've made it five] and throwing
that out in the extraction field... with each of these said matches being
seperated by a ellipsis [...]
All I did was conjure up a regular expression that basically just matches
words :-) haha ironically..
Here it is:
$extract_result=;
preg_match_all(/((?:[\w]+ ?){0,5})[\w
\.\,\-\;]((?:.join(|,$q_arr).))([\w]*)[\w \.\,\-\;]((?:[\w]+
?){0,5})/i,$row[content],$ext_matches,PREG_SET_ORDER);
foreach($ext_matches as $ext_arr) {
$extract_result .= $ext_arr[1]. B.$ext_arr[2]./B.$ext_arr[3].
.$ext_arr[4]. ... ;
}
Are you familiar with regex?
It really shouldn't be hard to implement a similiar concept with whatever
your current search system does.. My system as can be seen from this above code
actually breaks up the query string sent via the form on search page into each
word.. therefore you have an array [$q_arr] that looks like Array(
sufficient, large) ..
Hence in that regex above i just did a join using the | pipe symbol.. I
use this so when it joins all the words together they come out as:
word1|word2|word3
meaning regex will match 5 or less words before and after any of the given
words. the | symbol means bitwise OR, for example:
run(ning|ner)
will match running or runner but not runs
Sorry if you already know some of this I am just trying to make sure I
explain myself fully as I am unawares as to your experience level.
Anyway, so yes I simply use the handy preg_match_all function which will run
this regex statement upon the entire $row[content] which in my case is just
the entire content of the post which it found to match words in.. and from that
it simply matches these certain given keywords and their surrounding word/s..
I then use a foreach structure to simply iterate over each of the matches and
create the lovely string you see before you, it does this simply by reprinting
the original matched string, creating a B/B bold effect on the given search
word and adding an ellipsis at the end for simple athestic reasons..
If you want any more examples or clarification please feel free to ask..
Enjoy ;-)

Great site, Julien! Probably more involved than we need for our project,
but very, very impressive. I really like the CSS styling in particular. If
you could tell me how you are displaying the content within the extract
field, that would be very helpful.

Re: [PHP-DB] Ending session
Wow Miles
You certainly want to kill that session !!
Well done ;-)
Well I must admit I use a similiar tactic for user-leech session cookies:
function sessionKill() {
global $SYSTEM,$DB;
mysql_query(delete from sys_activity where
user_name='.$MEMBER[user_name].',$DB);
session_unset();
}
I used to do all that seperate unset'ing of session var's, but then learnt
it's useless and redundant.
Unset()'ing the session unregisters all attached variables.. hence what I
want it to do.
The mysql element is a system I use to track users logged into site..
Every page that they request on the system will insert a row into a table
listing their user_name, page they are on and time they last hit that
request.
That way I can display in their profile a list of last viewed pages, and
also I can run a timeout cron like php job which purges out these
activity entries after a set period [mine is 10 mins] which removes that
entry from the table, that way the table only holds the most recent pages
you have visited or been too..
In addition to this, I can also display when the user was last 'active' on
the system by using the most recent timestamp in these entries..
As for the logout principle, I actually use that function above, with just a
simple few lines in header source as follows:
if(isset($_GET[logout])) {
sessionKill();
header(Location: http://.$_SERVER[HTTP_HOST].$SYSTEM[WWW_ROOT;]);
exit(); //Purely a safe-guard, there is no reason the header function
wouldn't work, but we don't want them to continue on regardless..
}
I use a fairly high integration of header and library files to generate
content, and there is no non-dynamic page on the site, all of them refer to
the headers, and various dozen or more include libraries so therefore they
all parse a session.lib.php library that runs that above code and functions
for handling, manipulating sessions etc..
Therefore any page you goto on the site regardless of existing GET or POST
requests, as soon as a logout variable is set in the request URI then my
system will pick it up before any further processing [my session handling
lib is of course positioned fairly close to the start of the header
initialisation as session functions obviously require sending HTTP header
statements before content is generated to the HTTP client.] and simply kill
the session and redirect them to a front page..
I use this in conjunction with a simple button on the login form [once you
are logged in] or even a simple html anchor such as:
[ A HREF=?=$_SERVER[PHP_SELF]??logout=1Logout/A ]
provides an easy escape. One click they're out..
And as I mentioned above, because the session will be unset all variables
freed BEFORE any further processing, the header can continue initialising
and when it reaches the content generation and layout formatting it will try
accessing the now unset variables and draw up the default layouts [ie login
form instead of post-login form, etc]
So smooth and elegant ;-)
Enjoy..

How do you actually end $_session variables so the session actually

I found the session_write_close() command. I am not sure if this is the
correct command or not.
One prime example I am using is a $_session variable to track which user
account is active. I want to have a log off button which closes the
session off.
Ron
Ron,
This may be overkill, but on a failed login I did not want the ckval
variable hanging around in any form, hence:
session_unregister( ckval );
unset($_SESSION[ckval]);
unset( $ckval );
session_destroy();
Hope this helps - Miles
