[PHP] PHP FPM and OCI8 crashes
Hi,
Recently, I decided to use PHP FPM, installation went well, I configured it
with Nginx.
I can run php script without any issue.
But when I used a script to connect to Oracle database using oci module, I
got a blank page.
Below is the code I am using in script.
?php
$c = oci_connect(mydb, password, 'DEV');
if(!c)
{
$e = oci_error();
print htmlentities($e['message']);
exit;
}
else
{
echo 'br /Connection is OK';
}
?
If I run this script from command line it works well.
---
/usr/local/php/bin/php db_test.php
Connection is ok
--
But when I run it from Web it does not return any thing, I got following
error in FPM log, nothing else.
WARNING: [pool www] child 15712 exited on signal 11 (SIGSEGV) after
3986.160925 seconds from start
It is getting segfault.
Anyone can suggest what could be possible reason.

[PHP] Querying a database for 50 users' information: 50 queries or a WHERE array?
I have a MySQL database table with about 10,000 rows. If I want to
query for 50 specific users (so no LIMIT ORDER BY) then I seem to have
these choices:
1) SELECT * FROM table
This will pull in all 10,000 rows, not nice!
2) foreach ($user as $u) { mysql_query(SELECT * FROM table WHERE
userID=.$u); }
This will lead to 50 queries, again not nice! (maybe worse)
3) foreach ($user as $u) { $whereClause+= OR userID=.$u; }
This makes a huge SQL query. However, this is the method that I'm using now.
Is there some sort of array that can be passed in the WHERE clause,
containing all the userID's that I am interested in?
Thanks!

Yes there is but all the IDs in one string like this
$ids = $id1.', '.$id2.', ' ;
note : remove the last comma from the string
the make the query like this:
mysql_query(SELECT * FROM table WHERE
userID= in($ids ) }

http://what-is-what.com
what criteria are you using to get the stats for these 50 users?
also, wouldn't this be much better suited for the mysql mailing list?
if you know all the userids, then you could just do it as:
$sql = SELECT * FROM table WHERE userid IN (. implode(', ',
$usersids) .);
not very elegant, and I am not sure that the IN is any better than doing
50 mysql calls, but this is only 1 call, and gets you the data.
Are you querying the database to get the id's in the frist place? if
so, you could look at doing an inner join on the 2 tables.

I have a MySQL database table with about 10,000 rows. If I want to
query for 50 specific users (so no LIMIT ORDER BY) then I seem to
have
these choices:
1) SELECT * FROM table
This will pull in all 10,000 rows, not nice!
2) foreach ($user as $u) { mysql_query(SELECT * FROM table WHERE
userID=.$u); }
This will lead to 50 queries, again not nice! (maybe worse)
3) foreach ($user as $u) { $whereClause+= OR userID=.$u; }
This makes a huge SQL query. However, this is the method that I'm
using
now.
Is there some sort of array that can be passed in the WHERE clause,
containing all the userID's that I am interested in?
Thanks!

Much smaller than what you proposed in #3, and easier to make if your
user is list is already an array.

Bye, Marco Hi Marco, You may have to think of this problem a different way. How about about creating a job queuing system to handle the long running database queries. You will have to break it down into steps: User initiatives Query via AJAX call. System receives query and adds it to queue, return status of 'Added to queue' System daemon monitors job queue and runs / records status / stores results of jobs. Background process on web page monitors job status via AJAX calls and alerts user when complete. On linux systems, The pear module 'System Daemon' is very good for job queues and easy to install: [http://pear.php.net/package/System_Daemon] Hope this helps.

I mentioned that implode earlier, but there is also the underlying
question (which I also asked earlier)... how is he getting the 50 id's
to populate?
here are 2 other ways of skinning the cat:
using an inner join:
select table.* from table inner join othertable on (table.userid =
othertable.userid) where (use the way your getting the 50 id's here);
OR by using a subselect,
select * from table where userid IN (select group_concat(userid,

guess it all depends on how you want to do it... but that would make it
1 db query

Re: [PHP] Querying a database for 50 users' information: 50 queries or a WHERE array?
Another theoretical approach, given the grey areas, would be to add a field to your table to indicate these special users. I would call the field is_awesome and have it default to zero, because that's just the way it is. Then you can make your query SELECT * FROM users WHERE is_awesome=1. This method might make the code a bit more manageable as you could modify the users through a CMS rather than updating a hardcoded array.

don't continue iterating through the rest of your data set...

[PHP] htmlentities
Is there a way to only change accented characters and not HTML (Example: p /p a href =”” /a ) The syntax echo htmlentities( stripslashes(mysql_result($whats_new_result,0,message)) ) . \r\n; is doing everything (as I expect). I store breaking news within the database as HTML formatted text. I am trying to see if a work around is available? Do I need to do a variety of search / replace to convert the noted characters above back after htmlentities ? (I am just starting to get use to accented letters.) Thanks a lot for your help. Ron The Verse of the Day “Encouragement from God’s Word” http://www.TheVerseOfTheDay.info
Re: [PHP] htmlentities
You could store the accented characters in your DB if you set everything to UTF-8, including calling the SET NAMES utf8 MySQL command after connecting. I find this much easier than encoding/decoding.

[PHP] What would you like to see in most in a text editor?
Hello all you php coders out there, I'm doing an Open Source text editor (just a hobby) that's designed for PHP developers and is accessible through the web. This has been stewing for a while, and has gotten to the point where I can use it for my own work. I would like any feedback on things that people really like/dislike about their current editors, as I believe some of these things could be resolved in mine. I currently have username/password protection (with Salted-Hash passwords), a file-system browser, file loading/saving, and syntax highlighting -- and these things seem to work reasonably well. As well, most things about the editor are scriptable with JavaScript. This would seem to imply that in a few weeks I would have something useful. So I would like to get some feedback on what features people would most want, since I am still at a very flexible stage in development. If you would like to see what I have, you can go to un1tware.wordpress.com. You can also peruse the code at github.com/bhus/scriptr. In particular, the README on github gives a little bit better rationality for why something like this might be useful, and how things are currently structured. --Brad [ Yes, this is based on the layout of Linus' original post to comp.os.minix. ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

But I think I finally have something solid to build on. I would like some feedback on things people like/dislike about their current editors. I currently have a basic system working with a login, file browser, ability to load/save files and syntax highlighting working. All keystrokes are sent through a client-side JavaScript API built on JQuery. This would seem to imply that something usable is not more than a few weeks away, so I figured I would get some input now while things are still quite flexible. All suggestions are welcome, though not all will be implemented. If you want, you can visit the web site for the project at un1tware.wordpress.com. There's a link to a video demo, as well as a the current version of the source code to try out. As well, the project can be found at github.com/bhus/scriptr.

Hello all you php coders out there, I'm doing an Open Source text editor (just a hobby) that's designed for PHP developers and is accessible through the web. This has been stewing for a while, and has gotten to the point where I can use it for my own work. I would like any feedback on things that people really like/dislike about their current editors, as I believe some of these things could be resolved in mine. I currently have username/password protection (with Salted-Hash passwords), a file-system browser, file loading/saving, and syntax highlighting -- and these things seem to work reasonably well. As well, most things about the editor are scriptable with JavaScript. This would seem to imply that in a few weeks I would have something useful. So I would like to get some feedback on what features people would most want, since I am still at a very flexible stage in development. If you would like to see what I have, you can go to un1tware.wordpress.com. You can also peruse the code at github.com/bhus/scriptr. In particular, the README on github gives a little bit better rationality for why something like this might be useful, and how things are currently structured. --Brad [ Yes, this is based on the layout of Linus' original post to comp.os.minix. ] -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

+1 on terminal. For gui-based ones, i like to be able to syntax check my code and run it from within the editor window, tabs for dozens of files i usually have open at once, highlight that supports many languages as i can be working on many at once (php, css, js, ruby, python, C, lua, sql, for the ones i have open in geany atm), shortcuts are essential for things like find or replace in a selected area or what have you, regex support in search, and something that can be themed with white on black. For web-based ones, i never want to have to physically press anything to save my work, and i expect it to be within a few words if i just closed the browser and came back. It can't use any more resources than a usual web-page and has to be responsive. For other features to think about, built in version control system, ability to sync with github or really any cvs/svn/git repo, diff tool integrated into the editor, collaboration. Essential 1: utmost security, if they pwn your servers, they should not be able to have my data, this means that some part of what i pass to you in my credentials needs to not even reside on your servers (for example you can use the salted hash to check my the password, but the clear text version is still needed to decrypt that user's data store) and for the ultra paranoid, i should be able to further protect my data store with another password the hash for which you don't store, but rather store the md5 of the hash. Essential 2: reliability, i would like to be in an N+N+1 where the service and my data are both highly available without performance degradation when one of the services/servers goes kablewey (technical term) Enjoy. -- The trouble with programmers is that you can never tell what a programmer is doing until it’s too late. ~Seymour Cray On Tue, Sep 13, 2011 at 4:35 PM, Robert Cummings rob...@interjinn.comwrote: On 11-09-13 03:56 PM, Brad Huskins wrote: Hello all you php coders out there, I'm doing an Open Source text editor (just a hobby) that's designed for PHP developers and is accessible through the web.

Re: [PHP] Querying a database for 50 users' information: 50 queries or a WHERE array?
Hi, There are 2 peoblems with subselect 1. You cant use a limit on the nested select 2. Id the number of elements in the in clause exceeds the subselect buffer you will run into performance issues ans eventually you query will be doomed. Inner joins in,this is the best option for this . You can use a temp table for this On 14 Sep 2011 01:35, Alex Nikitin niks...@gmail.com wrote: On Tue, Sep 13, 2011 at 3:45 PM, Dotan Cohen dotanco...@gmail.com wrote: On Tue, Sep 13, 2011 at 21:34, Alex Nikitin niks...@gmail.com wrote: And this will be faster or at least more efficient with a limit (e.g. limit 50) this way when you have found the 50 users in the in statement, you don't continue iterating through the rest of your data set... The number is never exactly 50 but rather some arbitrary large number. But there is no need for LIMIT, that is the purpose of the _INNER_ JOIN. INNER means to only return the matching rows. -- Dotan Cohen http://gibberish.co.il http://what-is-what.com Dotan, IN (the function used in all of the queries above) is not the same as an INNER_JOIN, inner join joins 2 tables, as you have already described, IN however is a function that return 1 if the value being searched for is in the array of its values or 0 if it is not, thus IN is not an inner join, but a comparator function, thus if you are using IN, limit will indeed be more efficient than it's omission for exactly the reason i have stated in my previous post. Because your user array seems to be in php, and implode has been a topic of discussion above as well, setting an adequate limit is a simple task with the php's count function. This is all ofcourse void if the user array being pulled from mysql, in which case you could simply join the two tables to get your resulting data set. The trick there is to use the USING clause which seems to run a lot faster than any ON clause, or work on an optimized subselect, especially if you are running a cluster. -- The trouble with programmers is that you can never tell what a programmer is doing until it’s too late. ~Seymour Cray
