Re: [PHP] PHP internal memory
Daniel Kolbo wrote: Hello PHP-hipsters, I am not sure how to phrase these questions so please bare with me. I am thinking about performance of a single web server running Apache (non-cluster) with php as a module. I have a web app that requires the same php objects(classes) for each http request. First, I would like to have the web server keep these object/class definition files (code) permanently in the memory so the php engine does not have to keep loading and destroying these objects. Is this possible? Maybe the php engine is already smart enough to handle this. I imagine the engine is smart enough to not load the same class definition into memory for the same http request, but I'm not sure if the engine is smart enough to recognize that a class definition is already in the memory from a different http request. PHP maintains a "shared nothing" philosophy: http://en.wikipedia.org/wiki/Shared-nothing_architecture This means there are no application variables in PHP. To accomodate something of this nature you will need to use a memory cache like APC or whatnot. Second, furthermore, say two different http requests actually instantiate identical objects. Will both of these identical objects require their own space in the memory, or is the php engine smart enough to point both objects to the same memory (until something happens to one of the objects making it different than the other)? If not, i guess this is where the idea of caching comes in, and i have to be that smart one to define the unique keys... You would have two copies.. because PHP doesn't share like this. In fact, I do believe shared memory would still require a copy of the shared memory since I imagine marshalling the data back and forth between shared memory and PHP native datatype would occur. Third, when one caches php code using something like memcache, what is actually being cached: the human readable php, the parsed php, the serialized php (not really sure what this is), the raw cpu/assembly instructions, etc...? Usually the compiled bytecode is stored either in memory or on the filesystem if memory is lacking (less used caches would get punted to the filesystem). This saves the ocmpilation stage at the least which can be quite onerous for large libraries. And if everything fits in memory then you can really save on time. Fourth, where does this cached data live - on the server's hard drive or in the server's memory (assuming we have enough memory)? One or the other or both. Depends on your settings and the current memory needs. I assume one of the ideas behind the cache is to by-pass the php parser and instead just regurgitate the pre-chewed food and spit it out to apache. Thus, the memcache would only be storing the php output. Is this line of reasoning correct? And ideally it would be best to have this prechewed code sitting in the memory, but can I control this? It's a different kind of chache that stores the output... unless you meant the output of the parse stage. Just to be clear, I am familiar with the idea behind setting a unique key for the cache and all that. Also, i am not referring to client side caching. Well thanks for sticking with me, as I'm trying to learn these concepts. Any comments, answers, explanations would be most welcomed. Hope I've been of help.

Re: [PHP] PHP APACHE SAVE AS
as jim stated you'll get a "undefined function" error if php_mysql extension is not loaded. in this case probably the MySql server is not running, or not running on the default port (most likely the former) -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Thanks, Ash http://www.ashleysheridan.co.uk Try opening the php.ini file and uncommenting the line ;extension = php_mysql.dll; (by uncommenting i mean remove the first semi-colon). save the file and restart the apache service My guess is, that since he said that he is getting an error returned from the function call, that the function is being loaded, so the php_mysql.so is being loaded fine. But the problem, more then likely, lies with the arguments being passed to the mysql_connect function call itself. Check the values that you are passing to your function. But first, make sure that mysql is actually running. You should be able to use phpmyadmin, with the correct DB settings, and have it connect to the DB. If that doesn't work, try using a command line utility that came with your mysql installation.

Apache obviously does not know how to handle the .php files, so you need to update httpd.conf so it can both handle them and load php.

[PHP] connection to SSL enabled ldap problem
Hi all I am having a problem in connection to an SSL enabled ldap server. In localhost is easily connects to the ldap server with SSL but if try to connect remotely then it cannot bind to ldap server but can connect. In the slapd.conf I added the 3 lines to enable SSL TLSCACertificateFile /usr/local/openssl/misc/demoCA/cacert.pem TLSCertificateFile /usr/local/openssl/misc/server-cert.pem TLSCertificateKeyFile /usr/local/openssl/misc/server-key.pem and then restarted the ldap which is also working in 636 port. Currently its working in default port without SSL but whenever use the ssl then it gives the message : "Could not bind to ldap database" I have installed the rpms and in phpinfo there is a --with-ssl option too. Though I have generated the CA and server certificates with compiled openssl. Here is ldapconnect code; Any idea.
