I am absolutly new in PHP (I came from Java) and I am trying to set up XDEBUG on my PHP environement.
I am using XAMPP for the LAMP environment and PhpStorm as IDE so I am following this tutorial:
https://www.jetbrains.com/help/phpstorm/2016.3/configuring-xdebug.html#d45497e21
XAMPP put the xdebug DLL into this folder: C:\xampp\php\ext\php_xdebug.dll
So I am at stage 3 of the previous tutorial (To enable Xdebug, locate the [Xdebug] section in the php.ini file and update it as follows).
This is what I have add at the end of my php.ini file:
[Xdebug]
zend_extension="C:\xampp\php\ext\php_xdebug.dll"
xdebug.remote_enable=1
xdebug.remote_port="9000"
xdebug.profiler_enable=1
xdebug.profiler_output_dir="<AMP home\tmp>"
First I have set the location of the xdebug dll. Then I have set the port as 9000.
I don't know how to set the last line, this:
xdebug.profiler_output_dir="<AMP home\tmp>"
What is it? what represent? What kind of value have I to put here? (I think that it is a path but what?)
Then I have another doubt. Going forward with the previous tutorial it say that I have to do another step into this php.ini file, it says:
To enable multiuser debugging via Xdebug proxies, locate the xdebug.idekey setting and assign it a value of your choice. This value will be used to register your IDE on Xdebug proxy servers.
What exaclty is this Xdebug proxies? and why have I have to enable multiuser debugging ? What is it?
It say that I have to locate the xdebug.idekey setting in my php.ini file. But I have not this setting in my php.ini file. So what have I to do? Can I simply add it at the end of my php.ini file? What kind of value have I to set to it?
You don't have to install/configure multi user proxy. This is only nessesary if you have a Development envirement for multiple Users on the same Development Server.
MultiUser Proxy (simplified):
The multiuser Proxy is a layer between your IDE and your XDebug instance. Every request from the XDebug instance connecting to this Proxy and is then forwarded/backedup to the correct user.
Check you PHP configuration if Xdebug is enabled. Put in your index file:
echo php_info();
Then search for Xdebug and check if it's activated. Then you shoud see the default idekey and your configuration.
The xdebug.idekey you can set to any that you wan't. It's a string. You must only check that you set the same key in your IDE and your Xdebug configuration.
