I have a script scripty.php
Sometimes this script gets called through the browser.
Other times it gets called by another script on the server.
How can I (securely) check within scripty.php to see whether or not it is being called by the server?

1How does the script get called exactly from the server? Using include()? file_get_contents()? Using a file path or a http URL?Pekka– Pekka2011-09-05 19:36:32 +00:00Commented Sep 5, 2011 at 19:36

in the form of an http URL
The $_SERVER["REMOTE_ADDR"] variable that gives you the IP address of the client who made the request should be 127.0.0.1 when the script is called from the server.

Unless it is called from another script, that is from the browser... I understood it that way.

@Rok if a script on the server is making a
http:// call, that script will be the caller, not the browser. At least that's how I understand what the OP was saying in the commentRok Kralj
I meant script a.php is called from http:// and calls another script b.php. Therefore b.php
script is being called by another script on the server

Unfortunately it's not suitable for the development on local machine. You'll get
127.0.0.1 either way.jibiel
stackoverflow.com/a/7225638/535406 is seems to be a good solution relying only on script names — no additional constants or variables required.

you can create a variable before including your script
$by_script = true;
include("new_script.php");
and check it inside

Just a guess: You want to know, if the script its called trough a browser, or from CLI
var_dump(PHP_SAPI);

Yeah, maybe OP wanted it your way. It is hard to tell.
On any script that will be calling it define a constant like define("IN_SCRIPT") and within scripty.php you can check for the constant to determine if it's inside another script or not.
e.g.
if(defined("IN_SCRIPT")){
// We must be inside a script right now!
}
or
if(!defined("IN_SCRIPT")){
// We are working alone now
}

consider a file named test.php, this is the only code contained:
echo str_replace("\\","/",$_SERVER["SCRIPT_FILENAME"]);
echo str_replace("\\","/",__FILE__);
when a user execute* test.php by browser url, this is the output:
"C:/xampp/htdocs/test.php"
"C:/xampp/htdocs/test.php"
otherwise, differ (( in this case another.php was executed by browser url, who include test.php ))
"C:/xampp/htdocs/another.php"
"C:/xampp/htdocs/test.php"
