Heroku给了我这个错误，但Xampp不是

Question

$raw_query = "('{$this->input->post('phone')[0]}')";

Heroku is giving me error on this line. It says "syntax error, unexpected [, expecting }". This weird cause xampp is not giving me this error. Is it actually an error or is there something wrong with Heroku?

Answer 1

I had same problem, please do following

$tmp = $this->input->post('phone');
$raw_query = "('{'.$tmp[0].'}')";
unset($tmp);

It is caused of PHP version. (as far as I remember)
