[PHP] Mysql search query ignoring dots
Hi all,
I have to perform a mysql query in a table with millions of records.
I've full-text indexed my search field and I'm searching with MATCH AGAINST.
But there is a problem. In this field there are company names that
contain dots, for istance I've PO.SE. srl and I want to find it if
the user search for: POSE or PO.SE or P.O.S.E. etc.
I googled in the web but I don't find any solution. I don't want to
add a new field with the cleaned version of my string because I would
like to solve with the query and I prefer that the mysql table not
become too big. But if I will not find a different solution, I will
use this escamotage.
I've find a post that is similar but the solution don't seem to solve
my situation.
You can see it at the url:
http://forums.mysql.com/read.php?10,395557,395584#msg-395584
In my case replace(email, '.', '') = replace(theSearchValue, '.', '');
is indifferent and don't change my results.
My query, searching POSE, is:
select aziende.* from aziende where 10 AND
(MATCH(aziende.ragione_sociale) AGAINST('+POSE' IN BOOLEAN MODE) OR
(replace(aziende.ragione_sociale, '.', '') = replace('POSE', '.',
'')) order by aziende.ragione_sociale limit 0, 10
The alternative choice could be REGEXP but I've red that it make my
query slow in a table of millions of records and I don't know how to
exclude dots in the regular expression.
Can anyone help me?
Thanks in advance.

I don't see anything relevant regarding PHP. As for ' a table of millions
of records,' that sounds like questions for the DBA.

Well and good. My problem, however, is that I have multiple
applications in different tabs running on the same server, which may
all use the same sub-variables, like username. As a result, they
run into
each other.
One application will think I'm logged in when I'm not logged in to
that application, but to another in the same browser on the same box.
So my question is how to prevent this using the standard PHP
functions relating to sessions. I'd like different applications in
different tabs on the same box/browser to have different sessions,
so they don't share data.
Thoughts?
Paul
Using session_name will allow you to run two different sessions in the
same browser.
session_name('app1');
session_start();
Paul,
I'd would go with session_name($_SERVER['SCRIPT_NAME']) or
session_name(substr($_SERVER['SCRIPT_NAME'], 0,
strripos($_SERVER['SCRIPT_NAME'], '/')). My regex skills sucks so I can't
give
you a sample using regex. But you get the idea.
It's easier to get a particular app's relevant data to the URL while not
hard
coding the session name, eventually giving your app(s) more flexibility
especially if you may have multiple URLs mapped to an app serving
different purposes/clients.

Tommy
Forgot to mention that this assumes your app's design is MVC like with a
single point entry only.
Hey guys...
I too once tried this, basically so that I could stop users logging in
on multiple tabs, and if they did, then it would kill the previous login
(or not allow them to be logged in as they would be logged in still). I
had so many issues, that I abandoned it.
After reading this thread, I thought I would try Tommy's suggestion
about using a unique named session... so I just tried this:
?php
session_name(uniqid());
session_start();
echo session_id();
?
YAY! it worked!!
so then i tried this:
?php
session_name(uniqid());
session_start();
$_SESSION['t_'. time()] = time();
echo session_id();
echo 'pre';
print_r($_SESSION);
echo '/pre';
?
and it doesn't preserve the older session information... so I must be
doing something wrong. I can assume that because the name is being
regenerated new each time, that the old previous session is destroyed
(which would make sense) but then how can *I* ensure that each session
is going to be unique enough, but preserve old session information
too?
I know it has to be possible, as my bank doesn't allow multiple tabs
while online banking.

Steve,
The problem with uniqid() is it's based on unix timestamp, IIRC. So the
session name always changes and it's impossible to figure out what's the
previous session name is so how could you get the previously saved session
data. That's why I suggested the session name based on URL/URI. If the app
does not have a MVC like desgin, you could use a particular parameter's value
to ensure that session name is valid for certain purpose. For example:
http://server/training/schedules/ is different from
http://server/events/schedules/.
Should the person in charge of both needs to maintain them, it still could be
done getting the session_name based on the url requesting. Thus, you'd be able
to get the previously saved session data. Also, if the need arises, you could
also get data from different sessions if the business needs requires it because
you know exactly what the session name based URL is. As in the example above,
the maintainer could check to ensure that the certain scheduled items wouldn't
conflict each other in cases where the attendees are required to attend both :)

Tommy

Hello, What seems to be missing from this thread is talk about the root of the problem. You would never want to create the same cookie name for alike web-apps for the very reason Paul has discovered.

Extending Tedd's suggestion, Instead of a unique ID for a session name (most often session *cookie*), I really prefer a hash of something that results in a recognizable cookie name over something random. In my opinion only, it is a bit shady to create a cookie that is unrecognizable. At the least, when I am managing my own cookies, I will delete wierd cookie names. What I usually do for sessions is create a cookie name that is based on the domain, and also lists the word session... so a format something like: domain_session A format such as above lets the user know right away where the cookie comes from and what it does. I would post code, but I haven't written the hash in PHP yet. One last note about this hash, I always include a default to the IP address in the case of development, or if the site does not have a domain name. Oh, and one last last note, Accessing a web app with localhost does not work well with cookies either.. so in my hash, I redirect those who access my app from localhost to the localhost IP (127.0.0.1) right away. I know that last part is a bit complicated, but I help write the hash if the list is interested. I was really surprised to find no mention of this on the PHP's examples of sessions.

[PHP] preg_replace question
Hi there,
I am trying to replace certain words inside a text with php.
Unfortunatelly my function is creating invalid html as output.
For example the words beagle and welpen have to be replaced inside
this text: süße knuffige Beagle Welpen ab sofort
My result looks like this:
zwei süße knuffige a href=/bsp/hunde,beagleBeagle a
href=/bsp/hundeWelpen/a/a
The problem is, that my function is not closing the href tag before it
starts to replace the next item.
Here is the code:
// create internal links
function internal_links($str, $links, $limit) {
foreach($links AS $link){
$pattern[$k] = ~\b($link[phrase])\b~i;
$replace[$k] = 'a href='.$link[link].'\\1/a';
$k++;
}
return preg_replace($pattern,$replace,$str, $limit);
}
I
I could not find a way to fix this and I would be happy for some help.
Thank you in advance!
Merlin

What I usually do for sessions is create a cookie name that is based on the domain, and also lists the word session... so a format something like: domain_session A format such as above lets the user know right away where the cookie comes from and what it does. I would post code, but I haven't written the hash in PHP yet. One last note about this hash, I always include a default to the IP address in the case of development, or if the site does not have a domain name. Oh, and one last last note, Accessing a web app with localhost does not work well with cookies either.. so in my hash, I redirect those who access my app from localhost to the localhost IP (127.0.0.1) right away. I know that last part is a bit complicated, but I help write the hash if the list is interested. I was really surprised to find no mention of this on the PHP's examples of sessions.

Re: [PHP] preg_replace question
Without seeing the code that creates the arrays, it's tough to see the
problem. It looks like the first replacement is catching Beagle Welpen
entirely since the closing /a tag gets placed after Welpen. Then the
second replacement does just Welpen.
Also, you should have quotes around link when building the $replace[]
entry since the array access is outside quotes. Finally, you don't need $k
here at all.
// create internal links
function internal_links($str, $links, $limit) {
foreach($links AS $link){
$pattern[] = ~\b($link[phrase])\b~i;
$replace[] = 'a href='.$link['link'].'\\1/a';
}
return preg_replace($pattern,$replace,$str, $limit);
}

Re: [PHP] preg_replace question
If you declare your arrays, and set k to 0 first, put quotes around array
values and use the correct limit (you can default to -1), you will get
results, here is code and example (hopefully this helps you)
?php
function internal_links($str, $links, $limit=-1) {
$pattern=array();
$replace=array();
$k=0;
foreach($links AS $link){
$pattern[$k] = ~\b({$link['phrase']})\b~i;
$replace[$k] = 'a href='.$link['link'].'\\1/a';
$k++;
}
return preg_replace($pattern,$replace,$str, $limit);
}
echo internal_links(süße knuffige Beagle Welpen ab sofort,
array(array('phrase'=beagle,
'link'=http://google.com;),array('phrase'=welpen,
'link'=http://wolframalpha.com;)), -1);
Output:
süße knuffige a href=http://google.com;Beagle/a a href=
http://wolframalpha.com;Welpen/a ab

Hi there,
I am trying to replace certain words inside a text with php. Unfortunatelly my
function is creating invalid html as output.
For example the words beagle and welpen have to be replaced inside this
text: süße knuffige Beagle Welpen ab sofort
My result looks like this:
zwei süße knuffige a href=/bsp/hunde,beagleBeagle a
href=/bsp/hundeWelpen/a/a
The problem is, that my function is not closing the href tag before it starts
to
replace the next item.
Here is the code:
// create internal links
function internal_links($str, $links, $limit) {
foreach($links AS $link){
$pattern[$k] = ~\b($link[phrase])\b~i;
$replace[$k] = 'a href='.$link[link].'\\1/a';
$k++;

I could not find a way to fix this and I would be happy for some help. Thank

Do you have control over the building of the initial phrase = link assoc?
If so, reverse the order of these two items.

Because this is about developing in PHP in general, not what makes PHP work. You don't seem to be making the distinction. To clarify, again: This is not the place to ask. At best, you could use the Internals mailing list, but to be perfectly honest, I doubt you'll get the help you're seeking with what you've asked.

In the interest of speed it may be worth creating a table with just a
link id and the text to search which you can cleanup before inserting.
It will probably save you a headache in the future and will be quicker
than complicated queries.
The list of possible ids can then be tested against the full table for
any other criteria which if the table is indexed properly will be fast
too.
