How To Check if the cURL PHP extension is loaded
There is not a lot of information about checking if a particular extension is loaded and the few tidbits there are on the internet, are very impractical, so I decided to dig a bit deeper and I came up with my own solution.
The following function returns TRUE if it can find the cURL extension installed, and FALSE if it fails to find it.
// ### Checks for presence of the cURL extension.
function _iscurlinstalled() {
if (in_array ('curl', get_loaded_extensions())) {
return true;
}
else{
return false;
}
}
Sample usage:
if (_iscurlinstalled()) echo "cURL is installed"; else echo "cURL is NOT installed";
You may also use ‘function_exists’ function to check that. Simple code will be:
echo ‘cURL is’.(function_exists(‘curl_open’) ? ” : ‘ not’).’ installed’;
Hi Dmitry
Auch, that code is so much cleaner and simpler. Thank you for that tip, I never even thought to use the function_exists() function.
Thanks
Dmitry there is an error with your code. I was testing and of course it was giving me a false positive. curl_open is not a function, curl_init is what you should have tested with. Once I made the change I was getting a message saying cURL was enabled.
echo ‘cURL is’.(function_exists(‘curl_init’) ? ” : ‘ not’).’ installed’;
`if ( function_exists(‘curl_version’) == “Enabled” ){ //do something; };`
Virker også fint. // works a charm.
Hi Emil
I see my initial post was complete overkill, your method is definitely better to use
Good, your method is more useful.
…and your own code could have been much cleaner:
function _iscurlinstalled() {
return in_array(‘curl’, get_loaded_extensions())
}
Use below code : It tells every extension available in the current php set up.
