About the inability to add interceptors for mysqlnd-based PHP extensions in "PHP5.6"; Example: Pdo & Mysqli & Mysql about pinpoint-c-agent HOT 8 CLOSED

In PHP 5.6, the onBefore methods of these interceptors will not execute and there is no error message.But in PHP 7.2 they can work properly.

I also wrote some other interceptors.For example: Curl, Redis, Memcache, these interceptors can work either in PHP 5.6 or in PHP 7.2.

I tried in my env, agent runs normally, function in mysqli and pdo can be monitored.

[env]
php-5.6.39
pinpoint-c-agent: v0.1.1rc1

@yuslf Please clarify us the exact PHP version, include the minimum version number.

I tried on env with php 5.6.17 and centos6.9, Interceptors works normally:

[env]
php-5.6.17
pinpoint-c-agent: v0.1.1rc1
centos6.9

from pinpoint-c-agent.

OK... it should be my env problem. Thinks.
