some php functions broke after switching from trial > enterprise license

[mkaaaay]

It seems that after we switched to a paid license last night, some PHP are no longer working.
The code block below is now failing, where prior to switching off the trial license, it was not.

function makeXMLTree($data)
{
    $output = array();
    $parser = xml_parser_create();
    xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0);
    xml_parser_set_option($parser, XML_OPTION_SKIP_WHITE, 1);
    xml_parse_into_struct($parser, $data, $values, $tags);
    xml_parser_free($parser);
    $hash_stack = array();
    foreach ($values as $key => $val) {
        switch ($val['type']) {
            case 'open':
                array_push($hash_stack, $val['tag']);
                break;
            case 'close':
                array_pop($hash_stack);
                break;
            case 'complete':
                array_push($hash_stack, $val['tag']);
                if (isset($val['value'])) {
                    eval("\$output['" . implode($hash_stack, "']['") . "'] = \"{$val['value']}\";");
                }
                array_pop($hash_stack);
                break;
        }
    }
    return $output;
}

It's happening in multiple sites, even when caching is completely turned off.

Same on PHP 5.6, 7.0 and 7.3

Has anyone seen anything like this before?

Have you checked if php-xml is installed in EasyApache (4)?

 

[mkaaaay]

Yes it is. And was prior to the change to a paid license. FWIW, I tried setting it back to apache and that failed.

What about error_log? LiteSpeed is a web server, so why should it have effect to a specific PHP modul like php-xml....

 

[mkaaaay]

There's nothing in the error_log. It's failing silently.

well, we finally worked it out - super weird. XML was returning strange characters in header which was breaking the response causing makexmltree to return false.

No file had been touched to do this, the only thing we did was install the new license and LSWS did a graceful restart.

LIteSpeed doesn't own such files. LiteSpeed uses the same php as apache. ea-phpxxs are installed from cpanel repo. Could be some cpanel update with ea-phpxx-xml package upgraded.
