In PHP, how to detect the execution is from CLI mode or through browser ?

Php Problem Overview

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 ?

Solution 1 - Php

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.

Solution 2 - Php

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

Solution 3 - Php

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

(available in PHP >= 4.2.0)

Solution 4 - Php

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.

Solution 5 - Php

You can use:

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