HomeBackend DevelopmentPHP ProblemSolution to PHP cURL activation failure

When developing PHP applications, cURL is a very common library used to perform various network operations such as HTTP requests and file downloads. However, when installing and configuring cURL, you sometimes encounter some problems. One of them is that cURL extension cannot be enabled. This article will explore some of the possible reasons why cURL cannot start and introduce some solutions.

Cause 1: The cURL extension is not installed

The cURL extension needs to be enabled in the PHP installation. To check if PHP has the cURL extension installed, use the following command:

php -i | grep -i curl

If the following output appears, it means the cURL extension is installed Installed successfully.

cURL support => enabled
cURL Information => 7.64.0

If the above output does not appear, then you need to install the cURL extension. You can install the cURL extension with the following command:

sudo apt-get install php-curl (debian & ubuntu)

sudo yum install php-curl (CentOS)

After the installation is complete, just restart the PHP service.

Cause 2: The php.ini file is not configured correctly

The cURL extension needs to be enabled in the php.ini file. Please look for the following line in /etc/php.ini:

;extension=curl.so

Please modify it to:

extension=curl.so

Then, save the changes and restart the PHP service.

Reason 3: The libcurl library needs to be updated

Curl is a library used to make HTTP requests. If your libcurl library version is too old, it may cause the cURL extension to not work properly. You can update libcurl using the following commands:

sudo apt-get update && sudo apt-get upgrade libcurl4

##sudo yum update libcurl

Then, restart the PHP service.

Cause 4: php-cgi and php-fpm are not configured correctly

If you are using php-cgi or php-fpm, then you may need to perform additional configuration on the files for these services , to be able to use cURL extensions correctly. You can check if you have the correct configuration in your php.ini file. If you are not sure whether the configuration is correct, please check the PHP documentation.

Conclusion

In this article, we explored some of the possible reasons why cURL cannot start and introduced some workarounds. Ensuring that you have correctly configured the cURL extension and have the latest version of the libcurl library will ensure that you can successfully use the PHP cURL library to perform various network operations.
