How do i hard refresh php?

I have a php file and it doesn't update the right data from the server(apache) the first time I open it. I have to do a hard refresh ( Shift + refresh ) or (ctrl + f5) for the right data to appear in the browser. After I use hard refresh, everything works perfectly and i don't have to do a hard refresh again for the data to come in. I have tried different codes from stack overflow to clear the cache, but it couldn't give me a right result. So i wanted to know if there was a PHP function to do a hard refresh the first time i open the webpage so that my webpage works smoothly.

GOAL : Hard refresh automatically when the PHP page Loads up

code that my php file has at the moment

header("Cache-Control: no-cache, no-store, must-revalidate"); // HTTP 1.1.
header("Pragma: no-cache"); // HTTP 1.0.
header("Expires: 0");

i have also tried

header("Expires: Tue, 01 Jan 2000 00:00:00 GMT");
header("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT");
header("Cache-Control: no-store, no-cache, must-revalidate, max-age=0");
header("Cache-Control: post-check=0, pre-check=0", false);
header("Pragma: no-cache");

I am a HTML, PHP developer, but lately I am going crazy because the browser doesn't refresh the page when I make changes in the code, apparently the page is refreshed from cache and is not showing the changes. Could You fix that Please. I tried the recommendations of press Shift and the refresh button and the Control, Shift, R, key combination, but that doesn't work. Thank You Very Much.

Sorry to bring up this old thread again, but i have same problem with another site.

The site is only built with HTML.

The problem.

I have a div that i upload some picture to now and then and all new picture won't show up untill i press ctrl+f5.

This only happens with Firefox and not IE. The thing is that i run my FF with default settings, so all other users with FF should have the same problem.

What i've tried so far is

 [b]At all new picture[/b]

And some that i found on the web

# YEAR

  Header set Cache-Control "max-age=29030400"

# WEEK

  Header set Cache-Control "max-age=604800"

# 45 MIN

  Header set Cache-Control "max-age=2700"

# Turn on Expires and set default expires to 3 days
ExpiresActive On
ExpiresDefault A259200

# Set up caching on media files for 1 month

  ExpiresDefault A2419200
  Header append Cache-Control "public"


# Set up 2 Hour caching on commonly updated files

  ExpiresDefault A7200
  Header append Cache-Control "private, must-revalidate"


# Force no caching for dynamic files

  ExpiresDefault A0
  Header set Cache-Control "no-store, no-cache, must-revalidate, max-age=0"
  Header set Pragma "no-cache"

No one works. So is there any other solution?
