mysqli_real_escape_string() returns empty string

Question

I\'m using mysqli_real_escape_string() on an email address, and it returns an empty string. It does this with any email address.

Answer 1

I had this problem and found that my character set was set to latin. Solved by putting

$con->set_charset("utf8");

before the real_escape_string. Would be mysqli_set_charset in procedural style.
