[PHP7.0] htmlspecialchars() expects parameter 1 to be string, array given

[francesco-loreti]

Cause:

"htmlspecialchars() expects parameter 1 to be string, array given" into
Zend/View/Abstract.php line 905

Solution:
`
if (in_array($this->_escape, array('htmlspecialchars', 'htmlentities'))) {
return call_user_func($this->_escape, "{$var}", ENT_COMPAT, $this->_encoding);
}

    if (1 == func_num_args()) {
        return call_user_func($this->_escape, "{$var}");
    }

`
