I have a common script which Im including in my PHPcron files and the files which are accessing through the browser. Some part of the code, I need only for non cron files. How can I detect whether the execution is from CLI or through browser (I know it can be done by passing some arguments with the cron files but I dont have access to crontab). Is there any other way ?

Use the php_sapi_name() function.

if (php_sapi_name() == "cli") {
    // In cli-mode
} else {
    // Not in cli-mode
}

Here are some relevant notes from the docs:

php_sapi_name — Returns the type of interface between web server and PHP

Although not exhaustive, the possible return values include aolserver, apache, apache2filter, apache2handler, caudium, cgi (until PHP 5.3), cgi-fcgi, cli, cli-server, continuity, embed, isapi, litespeed, milter, nsapi, phttpd, pi3web, roxen, thttpd, tux, and webjames.

There is a constant PHP_SAPI has the same value as php_sapi_name().

(available in PHP >= 4.2.0)

I think you can see it from the $_SERVER variables. Try to print out the $_SERVER array for both browser & CLI and you should see differences.

You can use:

if (isset($argc))
{
    // CLI
}
else
{
    // NOT CLI
}
