Now a days script driven web applications are getting more and more complicated with background operations and triggered events. Debugging or event tracking is tough once the application is moved into production. Fresh and aspiring programmers are always too cautious to wade into deeper waters, and always go with line by line testing. Almost always in the course of debugging or code optimizations I see a lot of them using file_put_contents or echo to check variables at a particular point of execution.
I always gave the pressure to use a good logging system from the start itself, and to add level based message logging with debug_backtrace wherever needed. The most recent class abstraction for php programmers which is being used in our custom framework is attached to the downloads here. The file logging is being done after serializing, compressing and base64_encoding to keep logs in single lines, and to make sure they dont take up too much of the space.

Recently on Kerala News by Asianet, though the wp-simple-tags was there, the posts were not being tagged automatically. And on a detailed check I found it was due to a misconfiguration, and once the same was done properly the tagging started smoothly. But already a set of 8K posts were there with no or unrelated tags mistakes and un awareness of the operators who were posting to the site. Now I wanted these to be tagged properly.
I had already used the word-twit plugin and done some mods to the same, so it was more eaiser for me. Just went through the original code of word-twit and salvaged a small script which is attached here with as download.
require_once( dirname(__FILE__) . '/wp-load.php' );
The code above loads the wordpress system and initializes the wp variables and connects to the database.
Makesure we have the database abstraction object from wordpress, to select the posts, and do all the required manipulations on the same.
require_once( ABSPATH . 'wp-includes/class-snoopy.php' );
Include the inbuilt snoopy class, to mimic a web browser with the most simplicity.

Ever wondered how to capture the user input when writing php command line scripts ?
fwrite(STDOUT, "$msg: ");
$varin = trim(fgets(STDIN));
The function above is being used by me in certain command line scripts, where I need user responses.
