Frequently asked questions
Is escaping enough to prevent SQL injection?
It helps, but parameterized queries are the proper fix. Use prepared statements in code and treat manual escaping as a last resort.
Which characters get escaped in JSON?
Double quotes, backslashes and control characters like new lines and tabs are escaped. Everything else stays as it is.
Why escape text for a regex?
Characters such as dot, star and brackets have special meaning in regex. Escaping them makes the pattern match them literally.
