Compressing php source files for embedded applications

September 6th, 2011 Comments off

Compressing php code is not been a tough task, and this is not for the purpose of obfuscating or encoding to make closed source distribution. But to create compact files which can be distributed by pasting into inline text, or into email without the need for attaching. The size will be drastically reduced. Actually at Saturn we did this to help us achieve to load a whole application on to a very space constrained flash disk. We were the least bothered about the process cycles taken to evaluate the php files since they will happen only once in a blue moon when the embedded system restarts. I am pretty sure that for closing source, there are other solutions.

php-cron – schedule jobs to run by the second and more

January 6th, 2011 No comments

Yet another challenge, mostly like all other developers, ours at Saturn too believed that scheduled jobs could be run to the lowest frequency at every minute. This stands true if the job is handled only by *nix cron or by windows scheduler. For even further control one should write a Sleep-And-Run. I used to do this in shell script for most of my requirements. Just the other day some one challenged me to get done with one similar in php.

The outcome is a crude one, ServiceManager, which runs based on a configuration file and its run frequency. Best not to change the frequency or your configuration would never support anything less than the frequency as well as will only support multiples of the frequency. The configuration file is the famous ini file format with item names in square brackets, with configuration on two lines. The sample attached ServiceManager.ini should give an idea.

php smtp email direct to mail box delivery

January 5th, 2011 No comments

For sending status mails, with varying from addresses, for several of our projects at Saturn, we were using the phpmailer which uses our smtp server with authentication. Well our smtp host had a limitation of 250 emails per day. When our requirements grew out of this limit, mails started to pile up. Sure I could install exim4 or sendmail on my boxes, and that is what I did for immediate resolution. But here comes a new requirement, that the mails sent should be marked as such, and those which failed should be marked with the exact response of the receiving end mailserver.

At this point I thought about an SMTP direct to mail box Delivery system. My favorite language being PHP, and primary library being Google, I tried all possible ways, according to me, and they were not the right ones as I came to know later. All these did not get me in the right direction. And finally thought about writing one. Here too, being lazy, wanted to have the code from some ones work to ignite me. Okay I found the phpbb’s smtp.php referred on the net, and the function smtpmail from the same was the right choice.

A Mathematical Captcha – Reinventing the Wheel

April 19th, 2010 2 comments

For a long time I have been using the image captcha with random characters, and got fed up. I had seen numeric computational captcha or Mathematical captcha where one has to calculate the answer of an equation with simple arithmetic and supply the result for verification. Last night I was pondering over this while watching a movie on the TV. Well the out come is obvious.

Getting datetime type into JavaScript as Date object

March 25th, 2010 No comments

This is not any new thing and may be discussed at different other places. But just as I came across like any other things, I just wanted to make a record of this.

When selecting datetime to be displayed in a JavaScript ui library, select the unix_timestamp * 1000 from the sql.

Quick and dirty htaccess rewrite for Lighttpd

February 16th, 2010 No comments

Writing this post and am getting ready to hide behind strong walls, since mostly lighttpd is meant to fly light, or serve faster without the bloat and dynamic flexibilities. But certain situations may occur where one may have to forget the religion and behave sensibly. For a major project which was collaborated by different teams of our spread out offices, one part was developed by a team who were more exposed to benefitting the furls (friendly urls), by using apache rewrites. The bang off was detected only at the last moment of roll out to the beta deployment at client environment.

Posting to wordpress using php cli and xmlrpc

February 8th, 2010 9 comments

A reader once asked me if I could build a command line tool which takes title from one file, and content from another file to create wordpress post. I tried, which finally gave an outline to this script. I dont think that this is very high fly, but for those whom the xmlrpc is mumbo, this might be somthing worth looking into.

Migration from MySQL to MSSQL our solutions – Continued

December 14th, 2009 1 comment

In the previous post, I had specified that a code analysis would be presented later on, which is happening now. Though I am not permitted to abstract the whole database abstraction, which would otherwise divulge the core business logic of the system too, I do expect that the following would be enough to guide a MySQL PHP developer to port his application to MSSQL 2005. Mostly the compatablities are maintained. But for the database design, we had to let away some of the wonderful features from MySQL.

We started by a code auditing and reworked the system such that we did not use any group_concat through out the system. Also all timestamp and datetime fields were changed to varchar(19) since we were already feeding those fields with the php function date’s return value or ‘now()’. But there was quite a handful of areas where we were using STR_TO_DATE and with different formats. So this had to be handled in its own way. And it is here we started our regular expression war path.
