XF 1.5 if statement in config

[MattW]

I'm trying to switch the Memcached version being used based on the PHP version

Is going something like this possible in the config.php file?

if (phpversion() < "7") {
        $config['cache']['backend'] = 'Memcached';
} else {
        $config['cache']['backend'] = 'Libmemcached';
}

Yeah, it'll be fine.

You are using a comparison operator on a string though. I'm not sure if you can really do that in the way you intended it. if phpversion() is an integer you should have 7 as an integer I guess, not as a string.

phpversion() returns a string with the major and minor versions, and may return other info. IE: 7.0.15-0ubuntu0.16.04.4

So you'll need to explode that to get the major version out of the string. Other than that, the general idea of what you want to do would work.

I've added it per my original post, and it's returning the correct values on this specific server to switch purely based on the initial if statement.

# /opt/cpanel/ea-php56/root/usr/bin/php matt.php
5.6.30

# /opt/cpanel/ea-php70/root/usr/bin/php matt.php
7.0.16

# /opt/cpanel/ea-php71/root/usr/bin/php matt.php
7.1.2

Snog and Robust bring up good points that I didn't notice on my initial skim read. You can change your conditional to something like this to ensure it doesn't fall over in a case where the version isn't what you expect:

if (version_compare(phpversion(), '7.0.0', '<'))
{
    $config['cache']['backend'] = 'Memcached';
}
else
{
    $config['cache']['backend'] = 'Libmemcached';
}
