在unix上安装xdebug php profiler

Question

I want to start profiling some PHP code and I have that using xdebug and webgrind seems to be the way to go.

I downloaded xdebug and got these instructions..

Unpack the downloaded file with tar -xvzf xdebug-2.2.3.tgz
Run: cd xdebug-2.2.3

Now, this may be a stupid question, but where exactly should I upload xdebug to so it can be unpacked? Does it matter? I assume it shouldn't be web-accessible?

Answer 1

It is assumed you have Apache2 + PHP5 working already.

sudo apt-get install php5-dev php-pear

Now install xdebug thru PECL.

sudo pecl install xdebug

Now we need to find where xdebug.so went (the compiled module)

martin@martin-dev:/$ find / -name 'xdebug.so' 2> /dev/null
/usr/lib/php5/20060613/xdebug.so

Then edit php.ini:

sudo gedit /etc/php/apache2/php.ini

Add the following line:

zend_extension="/usr/lib/php5/20060613/xdebug.so"

Then restart apache for changes to take effect

sudo /etc/init.d/apache2 restart
