ob_start（“ob_gzhandler”）给出了错误

Question

I am using ob_start("ob_gzhandler") to gzip the response that I am sending from my API. It is working fine on my developer machine as well as on staging environment.

However, when I deployed my API in a production environment it is giving me an error that server is not responding.

I think there is some extension to be enabled for using gzip compression. Can you please help me in the resolution of the issue.

From php docs:

Note:

ob_gzhandler() requires the zlib extension.

Install the zlib extension. You can check if the extension is installed by executing the following code:

if (extension_loaded('zlib')){
    echo "zlib installed";
} else {
    echo "zlib is not installed";
}
