Well,

With:
QMAKE_CFLAGS += $$system(php-config --includes)

I get:
-I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM 
-I/usr/include/php/Zend -I/usr/include/php/ext 
-I/usr/include/php/ext/date/lib

and with:
PHP_INCLUDEPATH = $$system(php-config --includes)
PHP_INCLUDEPATH = $$replace(PHP_INCLUDEPATH, "-I", "")

INCLUDEPATH += \
   $$PHP_INCLUDEPATH

I get:
-isystem /usr/include/php -isystem /usr/include/php/main -isystem 
/usr/include/php/TSRM -isystem /usr/include/php/Zend -isystem 
/usr/include/php/ext -isystem /usr/include/php/ext/date/lib

The output of php-config --includes is:
$ php-config --includes
-I/usr/include/php -I/usr/include/php/main -I/usr/include/php/TSRM 
-I/usr/include/php/Zend -I/usr/include/php/ext 
-I/usr/include/php/ext/date/lib
