It can be implemented by the .htaccess file... but I'm not sure with PHP.
Here are 2 examples:

## EXPIRES CACHING ##
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpg "access 1 year"
ExpiresByType image/jpeg "access 1 year"
ExpiresByType image/gif "access 1 year"
ExpiresByType image/png "access 1 year"
ExpiresByType text/css "access 1 month"
ExpiresByType application/pdf "access 1 month"
ExpiresByType text/x-javascript "access 1 month"
ExpiresByType application/x-shockwave-flash "access 1 month"
ExpiresByType image/x-icon "access 1 year"
ExpiresDefault "access 2 days"
</IfModule>
## EXPIRES CACHING ##

and

# Set Cache-Control and Expires headers
<filesMatch "\\.(ico|pdf|flv|jpg|jpeg|png|gif|swf|mp3|mp4)$">
Header set Cache-Control "max-age=2592000, private"
Header set Expires "Sun, 17 July 2011 20:00:00 GMT"
</filesMatch>
<filesMatch "\\.(css|css.gz)$">
Header set Cache-Control "max-age=604800, private"
</filesMatch>
<filesMatch "\\.(js|js.gz)$">
Header set Cache-Control "max-age=604800, private"
</filesMatch>
<filesMatch "\\.(xml|txt)$">
Header set Cache-Control "max-age=216000, private, must-revalidate"
</filesMatch>
<filesMatch "\\.(html|htm)$">
Header set Cache-Control "max-age=7200, private, must-revalidate"
</filesMatch>

Thank you for your help but after i added you code to my .htaccess , my performance grade increased by just 2 and still the pingdom tools Recommend me to Leverage browser caching and set Accept-Encoding header.

set Accept-Encoding header means you have to set the encoding on each file you have... but I'm not sure how to do that!

But yes, you're welcome!
