Best way to access $_SERVER variables from c?

Hi All, I apologize if this is an extremely straight-forward question, but I'm trying to access the SERVER_NAME variable from PHP source (a tweak to protect against accessing disallowed directory paths in a shared environment without enabling safe mode). I've got the following code: if (zend_hash_find(PG(http_globals)[TRACK_VARS_SERVER]->value.ht, "SERVER_NAME", sizeof("SERVER_NAME"), (void **) &server_name) != FAILURE) { // Got server name php_error_docref(NULL TSRMLS_CC, E_WARNING, "Base directory: %s, %s, %s", basedir, path, server_name); return 0; } else { // Unable to find server name php_error_docref(NULL TSRMLS_CC, E_WARNING, "Unable to find server_name hash."); return 0; } However, the value that is reported as SERVER_NAME appears to be giberish (the call succeeds, but the value doesn't make sense). I'm getting "lEÊ·èEÊ·EÊ·" for the value of the server name. Any idea what is going on here? I've also tried the get_env function without success, but I'm guessing this is only valid when running as a CGI script as opposed to mod_php5. Note that I'm just using the php_error_docref as debugging output at this point. Regards, Glenn.
