here’s my code my parameter are same but it keeps giving me this error

i have tried changing the placeholders names but did not work

>Solution :

In your query you have quotes around the placeholder names, making them into strings.

If you remove them it should, hopefully, work.

Like this:

$query="INSERT INTO users (username,pwd,email) values(:userName,:pwd,:Email)";
