Php – TYPO3 Edit $GLOBALS at runtime in controller

Since TYPO3 itself does not support custom feature toggles in the backend, I wanted to build my own implementation for this.
I looked at the ConfigurationManager.php and it says in the comment at the top:
‘This class is intended for internal core use ONLY.

  • Extensions should usually use the resulting $GLOBALS[‘TYPO3_CONF_VARS’] array,
  • do not try to modify settings in LocalConfiguration.php with an extension.’

But if I now try to edit the globals in my action:
$GLOBALS['TYPO3_CONF_VARS']['SYS']['features'][$feature] = !$GLOBALS['TYPO3_CONF_VARS']['SYS']['features'][$feature];
The value only changes for a short time and after I reload the page, the value is reset again.

Am I missing something or is there another value I could go for?

    Edit Your typoscript with this

    plugin.tx_myextension {
    settings {
        enableFeature = 1
    }
}

    yourfile.php

        $featureToggle = $GLOBALS['TSFE']->tmpl->setup['plugin.']['tx_myextension.']['settings.']['enableFeature'];

// ext_localconf.php
$featureToggle = TYPO3CMSCoreUtilityGeneralUtility::makeInstance(TYPO3CMSCoreConfigurationExtensionConfiguration::class)
    ->get('myextension')['enableFeature'];

if ($featureToggle) {
    // Your feature is enabled
} else {
    // Your feature is disabled
}

    I made my own feature toggle in this way.

    An on/off switch as an extension configuration in ext_conf_template.txt

    # cat=feature toggle/enable/10; type=boolean; label=use feature
myFeature = 0

    Save it, ext_localconf.php

    // Register feature toggle
if (!isset($GLOBALS['TYPO3_CONF_VARS']['SYS']['features']['myFeature'])) {
    $myFeature = GeneralUtility::makeInstance(ExtensionConfiguration::class)
        ->get('myext', 'myFeature');
    if ($myFeature) {
        $GLOBALS['TYPO3_CONF_VARS']['SYS']['features']['myFeature'] = true;
    } else {
        $GLOBALS['TYPO3_CONF_VARS']['SYS']['features']['myFeature'] = false;
    }
}

    Use it in controller

        if (GeneralUtility::makeInstance(Features::class)->isFeatureEnabled('myFeature')) {
        $this->view->assign('myFeature', true);
    }

    In templates

    <f:if condition="{myFeature} == true">
