php_value post_max_size 5M
php_value upload_max_filesize 5M

</IfModule>
php_value memory_limit 300M – Set higher default php_value memory_limit in .htaccess
upload_max_filesize 5M - it increases default upload limit. The default upload limit is 2MB. the above htaccess increase increases file limit 2mb to 5 mb
php_value max_execution_time:
Set the number of seconds a script is allowed to run. If this is reached,
the script returns a fatal error. The default limit is 30 seconds or, if it
exists, the max_execution_time value defined in the configuration file. If
seconds is set to zero, no time limit is imposed.
php_value session.gc_maxlifetime:
The session.gc_maxlifetime only sets the age of the session files that will be deleted when
garbage collection runs.
If you have a busy web site with a lot of sessions being created, garbage collection will
run based on session.gc_probability/session.gc_divisor. Despite this being called
“probability” I tested this and it is strictly a count. Using the default
gc_probability/gc_divisor of 1/100, this means that garbage collection will run every 100
new sessions (Edit: Actually this occurs within the session_start() coding and would count
re-started sessions as well) and delete any existing session files that are older than the
session.gc_maxlifetime. There is no file locking on the session files, so active session
files will be deleted and things like users getting logged out will occur.
If this is on shared hosting and the session files are all kept in the default location and
someone else is using a smaller session.gc_maxlifetime or a more frequent
gc_probability/gc_divisor, then any of the session files will get deleted based on the
lowest value of gc_maxlifetime and the most frequent gc_probability/gc_divisor.
You need to increase session.gc_maxlifetime or make session.gc_divisor larger and if this is
on shared hosting, set session.save_path to be a location within your web space.

A Simple script that make our application works great. Yes, The following FBJS – FaceBook JavaScript will help you for part of page refresh in the facebook applications.
Uses:
1) Helps to retrieve data from your server database without refreshing the page
2) It would be useful for cricket scores and other live datas.
Mock AJAX Script as follows,
<script>
<!–
function partRefresh(){
var ajax = new Ajax();
ajax.responseType = Ajax.FBML;
ajax.ondone = function(data) {
document.getElementById(’partId’).setInnerFBML(data);
setTimeout(function() {partRefresh()},60000); // Making time delay
}
ajax.post(“http://www.example.com/filename.php”);
}
//–>
</script>
<div id=”partId”></div> // the output of filename.php is displayed here
<script>
partRefresh(); // Just calling the function on browser loads
</script>
