I know how this is meant. But without the added patch, it does not corrupt error_reporting. The problem is that your patch is not compatible to a webserver that runs more than one request per process (a multithreaded one), because it modifies the ini setting in a way that affects later running threads. I try to find a way to reproduce it in other webservers. This is the code that NSAPI uses to modify the INI entries: entry->param->name is the nullterminated ini key name, entry->param->value is the nullteminated value. This code runs on every request (like in apache a php_(admin)_value) that needs to set some specific ini-values. The server runs only *one* process that handles all requests in its lifetime because it is multithreaded: if (zend_alter_ini_entry(entry->param->name, strlen(entry->param->name)+1, entry->param->value, strlen(entry->param->value), PHP_INI_SYSTEM, PHP_INI_STAGE_ACTIVATE)==FAILURE) { log_error(LOG_WARN, pblock_findval("fn", NSG(pb)), NSG(sn), NSG(rq), "Cannot change php.ini key \"%s\" to \"%s\"", entry->param->name, entry->param->value); } . It is always runned with admin "privileges" because SJSWS does not have htaccess files. The big advantage to have the possibility to set ini values is, that it is not server-wide you can change the call to PHP SAPI e.g. per virtual server or URI path (see documentation of NSAPI). Uwe
