用双引号回复反斜杠的php字符串

Question

I have this string:

while($this->stmt->fetch()){
                $string=$string.'","'.$idRuolo;
                $i++;
            }       
            $str= ltrim($string,',"');

      $str=stripslashes($str); 

            echo json_encode($str);

I have tried everything but I can't delete the backslash from the result, this is the output:

"2\",\"1\",\"3"

this is what I want:

"2","1","3"

Answer 1

Try str_replace.

$str = str_replace("\\","",$str);
