在App Engine运行时PHP 7.2上启用Memcached

Question

I'm trying since several days to enable session storage in memcache on Google App Engine, using the Symfony framework. Application starts well, Memcached instance exists, but I always end up with sessions that are not stored (CSRF on all forms, etc).

So I've created a very simple POC to check if Memcached is working, and it actually doesn't.

Here's the POC code:

app.yaml

runtime: php72

resources:
  cpu: 1
  memory_gb: 0.5
  disk_size_gb: 10

php.ini

extension=memcached.so

index.php

<?php

$test = new \Memcached;
var_dump( $test->add('test', '42') );
echo 'value of test is: ', $test->get('test');

Result of the following code is:

bool(false) value of test is:

Memcache looks pretty well integrated to App Engine, so I'm wondering why I can't hit it.

Debugging Memcached, the error is the following:

(0x75b27c3c040) NO SERVERS DEFINED -> libmemcached/initialize_query.cc:58

Any idea how to configure it properly?

Answer 1

php72不支持Memcache，如果您需要访问memcache，则必须使用php55
