Technically it does have a microscopic speed increase, but unless you're pumping out hundreds or thousands of lines (like in a loop) you most likely won't notice it. In my code, I always try to use the proper quote marks because I *am* dealing with huge tables of data. I've said this a hundred times before, if you can shave off 0.001 from each row, then after 1,000 rows, you've shaved 1 second off the page time. That seems small, but that shit adds up. Caching will help, as the page is already parsed once, so PHP doesn't have to do the work again in many cases. To me, it's a good habbit and costs you nothing to do. The difference is that with " the PHP engine has to pre-process the string and look to see if there's anything interesting it needs to do -- such as replace any $var with their equivalents or \n or whatever else. A ' means to use it as is, so PHP just spits it back out. http://php.net/manual/en/language.types.string.php http://stackoverflow.com/questions/482202/is-there-a-performance-benefit-si ngle-quote-vs-double-quote-in-php http://stackoverflow.com/questions/13620/ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

It could be that you're just hitting the max number of connections that the server is configured to handle, or that the current number of connections is reaching the memory limit. Maybe the sessions are set up to be stored in files on the server on a separate partition, and that has reached capacity? There are a number of reasons which could cause the server to appear that the sessions are causing a problem that is not a DDoS attack ;) Thanks, Ash http://www.ashleysheridan.co.uk
Re: [PHP] How does php server identify that the particular session belongs to particular user
I agree with Ash's comment. You should probably dig in deeper and see if those IPs are indeed valid. Given the way the sites are being attacked (DDoS, SQL Injection et al), you could be seeing one. If you see a high load and your website is accessed by users spread globally, you should try out a Content Delivery Network like Akamai to meet the scale and improve the performance of your web-site without compromising on the end-user's site navigation experience.

[PHP] Using LDAPS with PHP / certificates
Hi,
I'm trying to contact an openLDAP from Apache server (on windows) using PHP
using LDAPS
Here is my sample code :
$host="ldaps://srvLDAP";
$port="636";
$ds=ldap_connect($host,$port);
ldap_set_option($ds,LDAP_OPT_PROTOCOL_VERSION,3);
$r=ldap_bind($ds,"cn=admin,o=exemple,dc=fr","exemple" );
$sr=ldap_search($ds,"o=exemple,dc=fr",("objectClass=exemple" ));
$info=ldap_get_entries($ds,$sr);
print $info["count"]." enregistrements trouvés.";
I passed lot of time trying configuring my servers and here is what i have
done :
First i configured my openLDAP server :
slapd.conf:
#cert requested for the ldapserver
TLSCertificateFile ./ssl2/srvLDAP.cer
TLSCertificateKeyFile ./ssl2/srvLDAP.key
#CA cert
TLSCACertificateFile./ssl2/cacert.cer
TLSVerifyClient never
ldap.conf:
TLS_CACERT ./ssl2/cacert.cer
TLS_REQCERT never
On my apache server i created a folder C:\openldap\sysconf
and created a file ldap.conf :
TLS_CACERT ./ssl/cacert.cer
TLS_REQCERT never
(I also created a folder c:\openldap\sysconf\ssl and put my CA certificate
inside it)
(of course I activated ldap and ssl in my php.ini)
>From now it DOES work BUT it doesn't verify any certificate.
I want now to make it verifying the certificate. I know i have to
change TLS_REQCERT never to TLS_REQCERT demand on openldap server
and apache server. I tryed but it doesn't work. I can't contact ldap server..
On the openLDAP I have this following error:
connection_read(1176): checking for input on id=0
TLS trace: SSL_accept:before/accept initialization
TLS trace: SSL_accept:SSLv3 read client hello A
TLS trace: SSL_accept:SSLv3 write server hello A
TLS trace: SSL_accept:SSLv3 write certificate A
TLS trace: SSL_accept:SSLv3 write certificate request A
TLS trace: SSL_accept:SSLv3 flush data
TLS trace: SSL_accept:error in SSLv3 read client certificate A
TLS trace: SSL_accept:error in SSLv3 read client certificate A
connection_get(1176): got connid=0
connection_read(1176): checking for input on id=0
TLS trace: SSL3 alert write:fatal:handshake failure
TLS trace: SSL_accept:error in SSLv3 read client certificate B
TLS: can't accept.
TLS: error:140890C7:SSL routines:SSL3_GET_CLIENT_CERTIFICATE:peer did not
return
a certificate s3_srvr.c:2471
connection_read(1176): TLS accept error error=-1 id=0, closing
connection_closing: readying conn=0 sd=1176 for close
connection_close: conn=0 sd=1176
That means that the openLDAP can't check the client certificate cuz PHP and
Apache don't send any to it.
I heard about a ldaprc file but I can't find any information about it...
Is there somebody who can help me with this ?
Thank you very much in advance.
[PHP] connect openLDAP server using LDAP (apache + windows)
Hi I'm writing from france cuz i'm having a big problem with apache and ldap. let me explain : I would like to make an Apache server communicate in php with en openLDAP server (both servers are under win srv 2003), using LDAPS protocol. In order to activate LDAPS on my openLDAP srv (srvLDAP), I created self signed certificates with openSSL. I got 3 files: cacert.pem srvLDAP.pem srvLDAP.key I configured my slapd.con file and ldap.conf fil (openLDAP side) like this: slapd.conf TLSCertificateFile ./ssl/srvLDAP.pem TLSCertificateKeyFile ./ssl/srvLDAP.key TLSCACertificateFile./ssl/cacert.pem ldap.conf BASE URI ldaps://srvLDAP/ TLS_CACERT ./ssl/cacert.pem TLS_REQCERT demand I launched my openLDAP service, and checked ldaps protocol was okay, using this command : C:\Program Files\OpenLDAP>ldapsearch -b o=exemple,dc=fr -s sub -x -w pass-D cn=admin,o=exemple,dc=fr -H ldaps://srvLDAP/ Now I would like, from the remote apache server, communicate with the openLDAP server using [b]LDAPS[/b] Protocol. Here is my simplified PHP code LDAP OPENLDAP LDAPS I get this errror: Unable to bind to server: Can't contact LDAP server I know i have to configure certificates in the Apache server configuration, I tried to to this according several internet ressources but didn't succeed.. I also read this link [URL=" http://forum.hardware.fr/hfr/OSAlternatifs/Logiciels-2/certificats-securisee-connexion-sujet_65365_1.htm"]Here[/URL] which is a french link which speak about an ldap.con and ldaprc files to put in the apache server. I did it but nothing happened. Well, i'm lost in all this stuff, that is why i'm asking for help to configure my servers to use ldaps with php. Do you have information that could help me ? I thank you in advance

[PHP] include and include_once inheritance
Hello, I've got a page that uses include_once to include a set of functions for use in that page. I later have another include_once pulling in another page, which generates a table. It relies on a function from the first file, yet an error is being generated undefined function, I thought that since the function was included in the main page, and that since the table file was also being included in the main page that the functions would also be available to the table file. Is this not so? Thanks. Dave. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
