PHP evitar cache

[petit89]

porque no usas htaccess?

Código Apache:

<FilesMatch "\.(css|flv|gif|htm|html|ico|jpe|jpeg|jpg|js|png|pdf|swf|txt)$">
    <IfModule mod_expires.c>
        ExpiresActive Off
    </IfModule>
    <IfModule mod_headers.c>
        FileETag None
        Header unset ETag
        Header unset Pragma
        Header unset Cache-Control
        Header unset Last-Modified
        Header set Pragma "no-cache"
        Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
        Header set Expires "Mon, 10 Apr 1972 00:00:00 GMT"
    </IfModule>
</FilesMatch>
