PHP 7.2.0, the create_function() is deprecated.

Thanks for your help,

or wait for developers?

Edited and cleared Code

return create_function( '', "
        global $chery_core_version;

        $path = trailingslashit( dirname( __FILE__ ) ) . 'cherry-core.php';

        $data = get_file_data( $path, array(
            'version' => 'Version'
        ) );

        if ( isset( $data['version'] ) ) {
            $version = $data['version'];
        }

        $old_versions = null;

        if ( null !== $chery_core_version ) {
            $old_versions = array_keys( $chery_core_version );
        }

        if ( is_array( $old_versions ) && isset( $old_versions[0] ) ) {
            $compare = version_compare( $old_versions[0], $version, '<' );

            if ( $compare ) {
                $chery_core_version = array();
                $chery_core_version[ $version ] = $path;
            }
        } else {
            $chery_core_version = array();
            $chery_core_version[ $version ] = $path;
        }
    " );

Just use a closure/anonymous function instead. [Read more](http://php.net/manual/en/functions.anonymous.php) — naththedeveloper, May 11 '18 at 07:48

`create_function()` has been deprecated and replaced many versions ago by [anonymous functions](http://php.net/manual/en/functions.anonymous.php). Anonymous functions are safer, faster and more flexible than the old `create_function()`. — axiac, May 11 '18 at 10:03

Use anonymous functions instead:

return function () {
    global $chery_core_version;

    $path = trailingslashit(__DIR__) . 'cherry-core.php';

    $data = get_file_data( $path, [
        'version' => 'Version'
    ] );

    if ( isset( $data['version'] ) ) {
        $version = $data['version'];
    }

    $old_versions = null;

    if ( null !== $chery_core_version ) {
        $old_versions = array_keys( $chery_core_version );
    }

    if ( is_array( $old_versions ) && isset( $old_versions[0] ) ) {
        $compare = version_compare( $old_versions[0], $version, '<' );

        if ( $compare ) {
            $chery_core_version = [];
            $chery_core_version[ $version ] = $path;
        }
    } else {
        $chery_core_version = [];
        $chery_core_version[ $version ] = $path;
    }
};
