Enable cURL in PHP in XAMPP, WAMP, Ubuntu and IIS Server

When running php scripts may be you have faces an error saying cURL not installed or not enabled. So to solve this error I'm giving you simple solution. Please follow the simple steps.

 This will work for XAMPP, WAMPP or directly PHP (who are not using any software for server.)

 For XAMPP :

  • Locate your XAMPP directory.
  • Open 'php.ini' file located at 'XAMPP\php\php.ini'
  • Now search for 'curl'.
  • Approximately on line no 952 you will get text like ';extension=php_curl.dll'
  • Now remove semicolon (';') from starting of line.
  • It is now 'extension=php_curl.dll'
  • Save file.
  • Restart Apache.


For WAMP : 

   Method 1 (Manually):
  • Locate WAMP directory
  • in WAMP directory open 'bin\php\php x.x.x'(according to your PHP version)
  • open 'php.ini' file. 
  • follow the same procedure as XAMPP from step 3.
   Method 2 :
  • Click WAMPP icon on system tray.
  • Select 'PHP > php extensions > php_curl' (see image)

For Ubuntu :

Run following command in Terminal. 



sudo apt-get install php5-curl
sudo service apache2 restart





And if you are not using any server above and using PHP with IIS server than follow the same procedure as XAMPP after locating 'php.ini' file in your PHP Installation directory.


Enjoy !

Linux File System Explained

In the Linux operating system, all filesystems are contained within one directory hierarchy. The root directory is the top level directory, and all its subdirectories make up the directory hierarchy. This differs to other operating systems such as MS-Windows which applies a separate hierarchy for each device and partition.

  • /bin -- binary applications (most of your executable files)
  • /boot -- files required to boot (such as the kernel, etc)
  • /dev -- your devices (everything from drives to displays)
  • /etc -- just about every configuration file for your system
  • /etc/profile.d -- contains scripts that are run by /etc/profile upon login.
  • /etc/rc.d  -- contains a number of shell scripts that are run on bootup at different run levels. There is also typically an rc.inet1 script to set up networking (in Slackwar), an rc.modules script to load modular device drivers, and an rc.local script that can be edited to run commands desired by the administrator, along the lines of autoexec.bat in DOS.
  • /etc/rc.d/init.d -- contains most of the initialization scripts themselves on an rpm-based system.
  • /etc/rc.d/rc*.d -- where "*" is a number corresponding to the default run level. Contains files for services to be started and stopped at that run level. On rpm-based systems, these files are symbolic links to the initialization scripts themselves, which are in /etc/rc.d/init.d.
  • /etc/skel -- directory containing several example or skeleton initialization shells. Often contains subdirectories and files used to populate a new user's home directory.
  • /etc/X11 -- configuration files for the X Window system
  • /home -- locally stored user files and folders
  • /lib -- system libraries (similar to Program Files)
  • /lost+found -- lost and found for lost files
  • /media -- mounted (or loaded) devices such as cdroms, digital cameras, etc.
  • /mnt -- mounted file systems
  • /opt -- location for “optionally” installed programs
  • /proc -- dynamic directory including information about and listing of processes
  • /root -- “home” folder for the root user
  • /sbin -- system-only binaries (see /bin)
  • /sys -- contains information about the system
  • /tmp -- temporary files
  • /usr -- applications mainly for regular users
  • /var -- mainly logs, databases, etc.
  • /usr/local/bin -- the place to put your own programs. They will not be overwritten with upgrades.
  • /usr/share/doc -- documentation.
Enjoy...!!!
