我在php.ini中具有以下设置，但它们未在phpinfo中显示

Question

I have apcu enabled - version 4.0.11 Apache version: Apache/2.4.6 (Red Hat Enterprise Linux) OpenSSL/1.0.2k-fips PHP/5.6.31

This is at the end of php.ini

apc.cache_by_default=On
apc.file_update_protection=2
apc.filters=
apc.max_file_size=1M
apc.num_files_hint=5024
apc.stat=1
apc.write_lock=On

I have also tried to put it in /etc/php.d/40-apcu.ini, but it had no effect.

I restarted apache after changing the files.

The reason I am trying to enable these variables is because we are upgrading to another server and these were the values on the old server. If they are no longer needed or supported that is fine, but I could not find any documentation saying that.

EDIT: Relevant PHP info

Answer 1

Edit: After updates, and further review. Zend OpCache

PHP > 5.5 doesn't included APC, hense the "APC Support Emulated" in your phpinfo. Instead, it has Zend OpCache replaces APC Opcache. APC had two parts. There does remain an APCu component of APC, for storing data, but all the settings you describe are specific to APC Opcache.

See: http://php.net/manual/en/opcache.configuration.php

You've got some troubleshooting to do

1. As you have a php.d/40-apcu.ini , it is possible that one of those is over-riding the values in php.ini

   • Usually the main ini file is loaded first, followed by those included in that directory, but this behavior is configurable. See: When do ini files in /etc/php.d/ get loaded? .

2. There may be some additional specific directives in the OS, or in Apache, to force some of those settings. If you didn't find an over-ride in the included ini files, you'll have to start a deep dive on apache config, and how it is started.

3. Don't forget that apache config directives like Directory and VirtualHost , as well as .htaccess , can be allowed to change these settings.

4. Last but not least, in many configurations, php code itself can set these directives with the ini_set() function.

Good Luck

Answer 2

I had the same issue, it was caused by entering the wrong phpinfo url.

Wrong url:

http://localhost/?phpinfo=1

Correct url (note the -1 parameter)

http://localhost/?phpinfo=-1
