New problem show up after install xampp portable :
Fatal error: Call to undefined function curl_init()
Hmm, seem that xampp not enable curl by default. To overcome this problem just open php.ini file that located in c:\xampp\php\php.ini using notepad.
Find ‘curl’ and hit enter :
remove ‘;’ sign, save the file.
Go to xampp folder.
Click ‘xampp_stop’ followed by ‘xampp_start’.
Done. You have working curl function that you can check using phpinfo() function.
