[PHP-DB] PHP MySQL High CPU on Query
I have a situation where a query run from PHP/Zend Framework on a MySQL database seems to hit the CPU harder than the same query run via the MySQL command line. The query is a simple SELECT statement querying 2 tables, 12 columns with a short WHERE clause that filters the results to less than 100 records. ZF is using the PDO adapter. I've seen the query cause mysqld to show a spike up to 50+% cpu while the query is run from a PHP call, and the same query from the client barely nudges the process to 1%. Is there something I can do to gather more data on what's going on and why this is happening? I'd expect some overhead, but that much of a difference seems wrong.

Re: [PHP-DB] Unknown column 'Test' in 'field list'
Change your query to this and make sure your ID field is set to
auto_increment
INSERT INTO entry (user_name) values ('$name')
That'll work for sure! ;-)

Hi All!
Hope I'm not bothering you nice people too much.
I have a account called Test, when I click the submit button I get this
error
Unknown column 'Test' in 'field list'
My table only has two fields id and user_name
I am not trying to insert the data into the field Test but into usre_name.
I had this problem once before but I can't remember how I fixed it or if I
ever did. Any ideas?
?php
if($action == Submit my entry){
if (!empty($name)){
$enter = insert into entry (id, user_name) values (' ',$name);
mysql_query($enter) or die(mysql_error());
}
exit;
}
$query=SELECT name FROM users WHERE uid=.$session[uid];
$ret = mysql_query($query) or die(myasql_error());
list($name) = mysql_fetch_array($ret);

Re: [PHP-DB] Contact Database php_mysql
Not so sure you need to go to that much detail in the linking of your tables. It's a good idea for the states, but the zip is usually just an integer anyway, so you can just store that with the record. Next, do you really need Full_Name??? You can extract that from the other two fields. As for city, that's going to be a HUGE table. The only advantage to making another table out of such is if you had more data per record and you need to search really fast. Just store that in with the Contact info the single table. The way I'd do it would be like this: [Contacts] ID int primary key auto_increment not null fname varchar(25) not null lname varchar(35) not null mname varchar(25) suffix varchar(5) addr1 varchar(35) addr2 varchar(35) city varchar(35) not null state int not null zip int not null [State] ID int primary key auto_increment not null state varchar(25) The field sizes are arbitrary, so think about what you're gonna need and size appropriately.

[PHP-DB] PHP4 LDAP
Not sure if this is the right list for this, but I didn't see any others on the PHP web site that made sense... I'm using the following packages: php-common-4.1.2-1mdk php-4.1.2-1mdk mod_php-4.1.2-1mdk php-ldap-4.1.2-1mdk openldap-clients-2.0.21-1.1mdk openldap-servers-2.0.21-1.1mdk openldap-2.0.21-1.1mdk libldap2-2.0.21-1.1mdk php-ldap-4.1.2-1mdk apache-modules-1.3.23-4mdk apache-common-1.3.23-4mdk apache-conf-1.3.23-3mdk apache-1.3.23-4mdk I'm trying to use my LDAP server for privilege access to certain portions of the site. I'm verifying the user's account information via LDAP and that seems to work ok, because I can bind and do a modify on the user's information. I'm updating a particular field to hold the sessionID and a time stamp. The record updates just fine, because I can do a ldapsearch from the command line on the server using the same credentials I use in PHP and I can see the update. I also have the server WIDE OPEN at the moment to test. I didn't want any stray ACL's to get in the way of debugging this. The problem arises when I try to read back all of the attributes within the PHP script. I can see only certain attributes: uid, mail, cn (the normal stuff) but if I try to read these fields that I want to use for the session, they don't print in PHP, but the show up from the LDAP command line util. The fields include: employeeNumber, carLicense, departmentNumber. Like I said earlier, I can update them from PHP, just can't read them back. Any ideas are greatly appreciated!

[PHP-DB] Re: PHP4 LDAP
Just in case anyone was wondering, here's a bit more info. I'm not sure why some attributes show up the other way though: ? $baseDN = dc=mydomain,dc=com; $bindDN = uid=dumbuser,dc=mydomain,dc=com; $bindPass = mypass; $linkID = ldap_connect(ldapServer,ldapPort); if ($linkID) if (ldap_bind($linkID,$bindDN,$bindPass) == false) DO SOME ERROR PARSING $filter = uid=dumbuser; $search = ldap_search($linkID,$baseDN,$filter); $entry = ldap_first_entry($linkID,$search); #- ALL TOO IMPORTANT LINE $values = ldap_get_values($linkID,$entry,departmentNumber); for ($i = 0; $i $values[count]; $i++) print $i . : . $values[$i] . br\n; ldap_close($linkID); ? Now (for some reason I haven't figured out yet) if you don't do the ldap_first_entry() step, you cannot access all of the attribute values returned from the $search! You can test by commenting it out and changing the $values line to use the $search value as the second arg. I hope that helps someone. I could have used it for sure.
