qmake has built-in sed(-ish) functionality, through the "~=" operator. 
Here's how to clean up the php-config output:

   PHP_INCLUDES = $$system(php-config --includes)
   PHP_INCLUDES ~= "s/-I/"
   INCLUDEPATH += $$PHP_INCLUDES

But it's simpler to use the replace() function instead:

   PHP_INCLUDES = $$system(php-config --includes)
   INCLUDEPATH += $$replace(PHP_INCLUDES, "-I", "")

(Note: no "$$" when specifying PHP_INCLUDES in the second line. 
replace() expects a variable as the first argument, NOT a string.)

However, I think Qt Creator is bugged and will not recognize the 
INCLUDEPATH here. Try and see.
