[PHP-DB] error handling
hello,
how can i use error_log( ) function
to capture the error occured in my server,
currently the Error warning is switched off
and i can't turn it on because it is in production server
the problem is the query miss some records,
and i didn't see it's error message
beside this code
$err=mysql_query($string);
if(!$err) {
error_log();
}
do i can get somekind of global error handling?
Something that can catch an error anywhere
in the codes,
thx

I am using the following script to maintain a login session on some

The sessions are stable and work fine EXCEPT when I run another PHP
script on the web page such as:
the script below does not call session_start()- you must call
session_start()
on each request that you need the session data, normally people put all
their session check/start-up stuff in a seperate file and then include that
when needed:
?
require db_connect.inc;
require session.inc;
// do you queries and output the results etc!
?php
// Make a MySQL Connection
require db_connect.inc;
// Retrieve all the data from the example table
$result = mysql_query(SELECT * FROM members WHERE Status='Inactive')
or die(mysql_error());
echo table border='1' cellpadding='0' cellspacing='1'
align='center';
echo tr thCertificate #/ththDan rank/ththFirst Name/th
thLast Name/th /tr;
// keeps getting the next row until there are no more to get
while($row = mysql_fetch_array( $result )) {
// Print out the contents of each row into a table
echo trtd;
echo $row['Cert_number'];
echo /tdtd;
echo $row['Dan_rank'];
echo /tdtd;
echo $row['First'];
echo /tdtd;
echo $row['Last'];
echo /td/tr;
}
echo /table;
?
I'm assuming that I am either not maintaining the session properly or
not linking the scripts to the session.
Any pointers on how to accomplish what I'm trying to do?
Thanks,

Re: [PHP-DB] variable and MySQL
Not entirely sure what you are wanting, but if you want a variable
variable, just use a double $ sign. eg:
$fred = 'var2';
$var2 = 'value of var 2';
echo $$fred;
will echo 'value of var 2'

[PHP-DB] Re: recommending a PHP book?
PHP 5 Power Programming by Andi Gutmans, Stig Bakken, and Derick Rethans may be worth the read for you. It doesn't mention an MVC, but they do talk a little about patterns in PHP. However, you probably won't find much in-depth coverage of patterns in PHP. There are alot of good books written on patterns in C++, Java, and C#, but PHP doesn't have that enterprise stigma about it. I've nearly finished an MVC-based framework in PHP, and think that Java should be sincerely evaluated before you take up the endeavor. I've had to reinvent alot of Struts functionality. Not only that, but you'll probably go further with J2EE on your resume than PHP. O'Reilly has some good books on design patterns. I picked up Head First myself, and though it was repetitive, it got the point across pretty well. You'll find that most of the code is in Java, but it should be easy to read if you speak PHP 5. For a quick online reference of some common design patterns (and if you can read C#), you can look at this site: http://www.dofactory.com/Patterns/Patterns.aspx#list Thanks, Jeremy Danny Lin wrote: Can any one recommend a good book that discusses MVC design patterns with PHP (and mySQL)?

Re: [PHP-DB] big data base
Martin Norland [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED] luis medrano wrote: Hi All, I need you help. I need to design a very big data base, around 900GB or more of information but I never had design or manage this magnitude of information before. I really appreciate if you can point me to documentation to how can do this properly or you can help me with some experiance you have doing this. I wasn't going to chime in, but after reading some replies I feel I have to. Bottom line - you need to give more details. The design of the database will not depend greatly on the amount of data inside it, unless there are operations/calculations to be done on/with it. Most people talk number of rows / tables / read|write operations / joins / etc. when talking database design, instead of size - as with proper indexes, the size can affect things very little. Ok... I don't completely agree with the Design of the database will not depend greatly on the amount of data, unless of course I am misinterpreting. If the size of the data and the usage rather simple one mind choose to ignore some of the rules when developing databases. I have seen databases pass my desk where parts of it aren't even in 3NF (3rd degree Normal Form). Then again, if the database is complex one might need to get into 4NF or BCNF. Also the design when it comes down to how to organise the database, storage wise, one might choose to seperate the database into several pieces - store one piece here and another there. It would suggest that the design is rather important if you do not wish to see the performance drop like a brick in water. Also if the data in the database is small you can easily get away with design mistakes, like bad index and the sort. While when the data is extensive one needs fast ways to get through the data. A table of several tens of thousands of records or more can take a long time to process when not having the right indexes and design schema's. I am wondernig though that if the size of the db is anyway related to the complexity and size of the project if PHP is the right choice of language. I would most likely move towards something like Java. Well just a thought... For example - if you're designing a database to store 20GB raw movie files - then you might want to rethink storing the gigs of data inside the database, then suddenly you aren't working with a large database at all. So, if you can't give more details - you're going to have to search on your own. Otherwise, you might want to speak up with some more info so you can get better recommendations. My only suggestion with the information you've given - is basically what Bastien said - multiple big iron and big fast hard disks / SAN. Other than that, I can only suggest that you design it well P.S. - I wanted to toss in a troll reply about trying SQLLite, since it comes with PHP! - but that's mean P.P.S. - I was also tempted to link to a great tutorial on this - an arbitrary resume writing tutorial, as a mean spiteful joke about being in over your head - but that's just too mean. It all depends on the system requirements, your budget, and your time. Just because someone may be in over his head one shouldn't try?
