如何在PHP / XAMPP中启用cURL

How do I enable cURL in PHP?

Since you're using XAMPP, uncomment the line

;extension=php_curl.dll

in xampp\apache\bin\php.ini, and then restart the Apache service.

NB: In newer XAMPP versions, PHP has moved to root xampp folder xampp\php\php.ini.

You can check phpinfo() (create a script containing and browse to it). This will tell you if you really do have it enabled. If not, read here.

It is not recommended for the faint-hearted Windows developer.

You compile your PHP using --with-curl.

On Debian with Apache 2:

apt-get install php5-curl
/etc/init.d/apache2 restart

(php4-curl if it's php4)

Actually I did it by uncommenting extension=php_curl.dll in the xampp\apache\bin\php.ini file.

Since XAMPP went through some modifications, the file is now at xampp/php/php.ini.

If you're are using MAMP, cURL is enabled by default.

Basic tip: After enabling the CURL in php.ini file, you need to restart the web server to make it work (my experience says).

I found the file located at:

C:\xampp\php\php.ini

Uncommented:

;extension=php_curl.dll

In SUSE Linux:

zypper in php5-curl
rcapache2 restart

Steps for Windows 7:

Ensure that the php.ini file that the PHP engine uses is the one you think it is.
Ensure extension_dir in php.ini is correctly set to the ext folder
Ensure extension=php_curl.dll in the php.ini is uncommented

Finally and maybe the one most people don't know: 4. Ensure that there are these two files in the Windows System32 folder: libeay32.dll ssleay32.dll If not there, you may copy these two files from the php folder.

For Ubuntu (and probably all Debian-Based) Linux Distributions:

sudo apt-get install php5-curl
sudo /etc/init.d/apache2 restart

You might have seen PHP Fatal error: Call to undefined function curl_init() before.

to install php5-curl under opensuse:

sudo yast2

->software ->software management ->search for curl ->check php5-curl case and accept.

after installation you need to restart apache server

service apache2 restart

For windows OS users (It worked for me) in XAMPP.

step 1: Go to C:\xampp\php\php.ini

edit this file php.ini

find curl- you will see a line ;extension=php_curl.dll.

remove semicolon (;)extension=php_curl.dll. so this line looks like

;extension=php_curl.dll

extension=php_curl.dll

step 2: copy ssleay32.dll, libeay32.dll from php folder. paste it in C:\Windows\System32\

step 3: Restart the system . Curl will run successfully.

check if curl module is available

$ ls -la /etc/php5/mods-available/

enable the curl module

$ sudo php5enmod curl

Check the php version, If you installed php 7.0 version

sudo apt-get install php7.0-curl
sudo service apache2 restart

If you installed php 5.6 version

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

PHP 7^ version:

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

If none of the above solves your problem and have installed with php-x86 (Windows 32 bit), then problem may be of openssl - for more info : How to fix libeay32.dll was not found error
