Summary:
- PHP uses a SAPI ("server API") to determine how it interacts with the caller
(e.g., how to read the environment, how to read flags, what code to execute).
- There are several different SAPIs: cli, cgi, cgi-fcgi, apache, etc.
- Each SAPI has different behavior -- for instance, the "cgi" SAPI emits some
CGI headers unless told not to, so a script like 'echo "x"' actually echoes some
headers and then 'x' as an HTTP body.
- In some setups, "php" may be php-cgi.
- If you run php-cgi as "php scriptname.php" and your ENV has an existing CGI
request in it, it runs that CGI request instead of the script. This causes an
infinite loop.
- Add checks to verify that "php" is the "cli" SAPI binary, not some other
SAPI.
- In particular, cPanel uses suphp and is affected by this configuration
issue. See this thread:
https://lists.marsching.com/pipermail/suphp/2008-September/002036.html
Test Plan:
- On a cPanel + suphp machine, ran setup and was stopped for having the
"cgi-fcgi" SAPI instead of throw into an infinite loop.
- Applied the suggested remedy, setup now runs fine.
