I'm not sure why, but xdebug does not highlight var_dump(). But config seems to be fine. Have no idea why... Any suggestions?
This is my phpinfo(); http://pastebin.com/A45dqnWN
plus even xdebug_var_dump() doesn't highlight anything. It works, but look like normal var_dump().
For Xdebug 3 you need to enable develop mode in your php.ini:
xdebug.mode= develop
You can also use multiple modes at once as explained here.
Nothing is enabled. Xdebug does no work besides checking whether functionality is enabled. Use this setting if you want close to 0 overhead.
Enables Development Helpers including the overloaded var_dump().
Enables Code Coverage Analysis to generate code coverage reports, mainly in combination with PHPUnit.
Enables Step Debugging. This can be used to step through your code while it is running, and analyse values of variables.
Enables Garbage Collection Statistics to collect statistics about PHP's Garbage Collection Mechanism.
Enables Profiling, with which you can analyse performance bottlenecks with tools like KCacheGrind.
Enables the Function Trace feature, which allows you record every function call, including arguments, variable assignment, and return value that is made during a request to a file.
You can enable multiple modes at the same time by comma separating their identifiers as value to xdebug.mode: xdebug.mode=develop,trace.
As mentioned by @Shadoweb for Xdebug v3 you want debug to allow stopping at breakpoints, and develop to format the var_dump
The following you'll likely want in php.ini therefore:
xdebug.mode=develop,debug
As an aside, I also needed xdebug.start_with_request=yes to replace the renamed xdebug.xdebug.remote_enable=1 setting to get step debugging working in my IDE.
