Hi everyone,

I was wondering if converting POST input from an HTML form into html entities, (via the PHP function htmlentities() or using the FILTER_SANITIZE_SPECIAL_CHARS constant in tandem with the filter_input() PHP function ), will help defend against any attacks where a user attempts to insert any JavaScript code inside the form field or if there's any other PHP based function or tactic I should employ to create a safe HTML form experience?

Sorry for the loaded run-on sentence question but that's the best I could word it in a hurry.

Any responses would be greatly appreciated and thanks to all in advance.
