PHP Version conflict

[mambax7]

We say that this version supports PHP 5.3.9

But in \htdocs\class\libraries\vendor\composer\autoload_static.php

we have in line 472:

}, null, ClassLoader::class);

However Class name constant is only allowed since PHP 5.5

Are we bumping up the minimum version to PHP 5.5, or are we refactoring it?

Similar issues in some of the libraries:
line 103 in \htdocs\class\libraries\vendor\paragonie\random_compat\lib\random_bytes_dev_urandom.php
'stream_set_chunk_size' is available starting with 5.4 PHP version

line 36 in \htdocs\class\libraries\vendor\smottt\wideimage\lib\WideImage\Mapper\WEBP.php
'imagecreatefromwebp' is available starting with 5.4 PHP version

line 41 in \htdocs\class\libraries\vendor\smottt\wideimage\lib\WideImage\Mapper\WEBP.php
'imagewebp' is available starting with 5.4 PHP version

All of these instances are version aware -- using newer functions only when available.

Looking at the context in \htdocs\class\libraries\vendor\composer\autoload_static.php at line 472 shows:

        $useStaticLoader = PHP_VERSION_ID >= 50600 && !defined('HHVM_VERSION') && (!function_exists('zend_loader_file_encoded') || !zend_loader_file_encoded());
        if ($useStaticLoader) {
            require __DIR__ . '/autoload_static.php';

            call_user_func(\Composer\Autoload\ComposerStaticInit6352cb8ef79af2c7649e83bf921c4678::getInitializer($loader));
        } else {
 ...

In line 103 in \htdocs\class\libraries\vendor\paragonie\random_compat\lib\random_bytes_dev_urandom.php
'stream_set_chunk_size' is available starting with 5.4 PHP version

                if (is_callable('stream_set_chunk_size')) {
                    stream_set_chunk_size($fp, RANDOM_COMPAT_READ_BUFFER);
                }

It appears that WideImage\Mapper\WEBP should indicate that webp is not a supported format when run in PHP 5.3. Not as graceful as the other two, but effective.
