Oh my God, Things are going so fast …

xdebug_and_apd_for_xampp-1.6.3.tar.gz (hosted @ box.net)

And  now, I can go on holidays!

Have a nice profiling

For all web developers willing to profile their scripts, you will find below an archive containing xDebug and apd compiled for Xampp 1.6.2 under linux.

xdebug_and_apd_for_xampp-1.6.2.tar.gz (hosted @ box.net)

Copy your archive in the /opt folder, then uncompress it and restart your xampp server :

cp xdebug_and_apd_for_xampp-1.6.2.tar.gz /opt

tar -xvzf xdebug_and_apd_for_xampp-1.6.2.tar.gz

lampp/lampp restart

This archive features xdebug.so, apd.so and php.ini configured so you will just need to restart your web server after uncompressing it.

Then, each time a PHP script is executed, a cachegrind.out file will be created in /tmp . This file is a trace of the whole script’s execution and brings a clear look on what is going on while the script is running. I suggest opening this file with kCachcgrind :

You can also use the xdebug functions inside your code (at the end of the main script):

if (extension_loaded('xdebug') ) {

    echo "<p>Memory Usage : "  . xdebug_memory_usage(). "</p>";

    echo "<p>duration : "  . xdebug_time_index(). "</p>";

}

that will print :

Memory Usage : 251992

duration : 0.00704598426819

Enjoy, and have a nice profiling

Pear::DB is deprecated in favor of Pear::MDB2. I guess this is a good thing because MDB2 is faster, smaller and provides more features. I only guess because I am not a pear user,I do not like Pear as its installation is really weird and the documentation is sometimes insufficient.

By now, two database abstractions are still active in the PHP community : PDO & Pear::MDB2. I recommend PDO If you are writing your application using PHP5 and/or you want your application to be really fast (PDO is a PHP inner class). Pear::MDB2 can be a good thing for PHP4 applications or if you need a high-level of database abstraction in your application.
