Form Validation Using PHP
Very first we have to create a form in html setting action “#” and
method “POST” with some fields, when a user clicks on submit button all
the data starts travel in URL but it will be hidden, as we set method =
“POST”.
Now, on page refresh, PHP code runs, all values fetches from URL into PHP variables and aplying “preg_match ( )“ function on them.
