Re: php7

EHLO (o;

This fixes (at least for me) the "ibfind" crashing on Debian 9 and
php-7.0.27:
Length is now "size_t" in php-7.x

#define FUN_STRING(functionName) \
ZEND_FUNCTION(functionName)    \
{    \
  char *s;    \
  size_t s_len;    \
  int r;    \
  if (zend_parse_parameters(ZEND_NUM_ARGS() TSRMLS_CC,     \
                "s", &s , &s_len    \
                ) == FAILURE) {    \
     RETURN_NULL();    \
  }    \
   r = functionName(s);    \
   RETURN_LONG(r);    \
}

Though still no data returned with ZVAL_STRINGL in "ibrd"...
