I have same problem with the most basic situation and my problem was solved with inserting this meta in the head:

<meta charset="UTF-8">

the character encoding (which is actually UTF-8) of the html document was not declared

You have to change the file from  html to  php    and add this following line  header  Content-Type  text html  charset utf-8

User · Answer

Add this as a first line in the HEAD section of your HTML template   lt meta content  text html charset utf-8  http-equiv  Content-Type  gt   lt meta content  utf-8  http-equiv  encoding  gt

Well when you post  the browser only outputs  title - all your HTML tags and doctype go away  You need to include those in your insert php file     lt  DOCTYPE html PUBLIC -  W3C  DTD XHTML 1 0 Strict  EN   http   www w3 org TR xhtml1 DTD xhtml1-strict dtd  gt   lt html xmlns  http   www w3 org 1999 xhtml  gt   lt head gt   lt meta http-equiv  content-type  content  text html  charset utf-8    gt   lt title gt insert page lt  title gt  lt  head gt   lt body gt   lt  php       title     POST  title        price     POST  price       echo  title       gt     lt  body gt   lt  html gt

Your initial page is a complete HTML page containing a form  the contents of which are posted to insert php when the submit button is clicked  but insert php needs to process the form s contents and do something with them  like add them to a database  or output them to a new page  Your current insert php just outputs the contents of the title field  so your browser tries to interpret that as an HTML page  and fails  obviously  because it isn t valid HTML  i e  it isn t contained in an  HTML  tag  etc     Your insert php needs to output the necessary HTML  and insert the form data in there somewhere   For example    lt  php       title     POST  title        price     POST  price       echo   lt html xmlns  http   www w3 org 1999 xhtml  gt      echo   lt head gt      echo   lt meta http-equiv  content-type  content  text html  charset utf-8    gt      echo   lt title gt      echo  title    echo   lt  title gt      echo   lt  head gt      echo   lt body gt      echo  Hello  world      echo   lt  body gt        gt
