Browser timeout, the browser will not stay and wait for a page without any
output for ever. If you have a script that does a lot of background job, you
need to make it to output something once in a while so that the browser won't
think that the server timed out and break the loading, which leads to that the
execution of the php script is terminated.

You need to modify the /etc/crontab on the machine that you have the php
script on, for details how to set up a correct crontab line, you should read
the man page (man crontab)
You need to make the php script to be executive, you will need to tell the
script where to find the php binary, eg:
#!/usr/bin/php
--- example script ---
#!/usr/bin/php
<?PHP
echo date('Y-m-d');
?>
--- end of file ---
When you have your script, you have to set the executive bit on
chmod 755 /path/to/the/script.php
This makes it's read/write/exec byy the owner, read/exec by the group and
read/exec by everyone else.
