Add two input values as string in Codeigniter

I´m trying to add two input values as string not as number, the problem is that they are actually numbers.

'clabe' => $this->input->post('clabe2') + $this->input->post('dc')

Where clabe2 = 123 and dc = 4;

I want to get result as 1234 not 127

Any help will be appreciated

Solution

Do something like this

Use concatenation operator . for string concatenation

'clabe' => $this->input->post('clabe2') . $this->input->post('dc');
