Description:
------------
When executing a php script through CLI that has been triggered with shell_exec() from a script that was running under Apache, the newly spawned cli script contains all the HTTP related variables in $_SERVER, and it shouldn't.
In apache config I have a VirtualHost with the following:
ScriptAlias /cgi-bin/ /usr/local/Cellar/php/7.4.8/bin/
AddHandler php-cgi php
Action php-cgi /cgi-bin/php-cgi
Test script:
---------------
<?php
echo '<pre>';
echo php_sapi_name().PHP_EOL;
if (php_sapi_name() == 'cli') {
print_r($_SERVER);
} else {
echo shell_exec('/usr/local/bin/php '.__FILE__);
}
echo '</pre>';
Actual result:
--------------

It could be, but if I run the same script under a PHP installed as an Apache module instead of CGI, I get a more expected result, like below: ------------ apache2handler cli Array ( [TERM] => xterm-256color [SHELL] => /bin/sh [USER] => root [SUDO_USER] => ibra [SUDO_UID] => 501 [SSH_AUTH_SOCK] => /private/tmp/com.apple.launchd.mZTvWkrOyN/Listeners [__CF_USER_TEXT_ENCODING] => 0x46:0:0 [PATH] => /usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin:/Applications/VMware Fusion.app/Contents/Public:/opt/X11/bin:/Library/Apple/usr/bin:/Library/Frameworks/Mono.framework/Versions/Current/Commands:/Applications/Wireshark.app/Contents/MacOS [MAIL] => /var/mail/root [_] => /usr/local/bin/php [PWD] => /Users/ibra/Documents/work/www [HOME] => /Users/ibra [SUDO_COMMAND] => /usr/local/bin/apachectl restart [SHLVL] => 2 [LOGNAME] => root [LC_CTYPE] => UTF-8 [DISPLAY] => /private/tmp/com.apple.launchd.UjxqYiGZnM/org.macosforge.xquartz:0 [SUDO_GID] => 20 [PHP_SELF] => /Users/ibra/Documents/work/www/test.php [SCRIPT_NAME] => /Users/ibra/Documents/work/www/test.php [SCRIPT_FILENAME] => /Users/ibra/Documents/work/www/test.php [PATH_TRANSLATED] => /Users/ibra/Documents/work/www/test.php [DOCUMENT_ROOT] => [REQUEST_TIME_FLOAT] => 1595579540.9974 [REQUEST_TIME] => 1595579540 [argv] => Array ( [0] => /Users/ibra/Documents/work/www/test.php ) [argc] => 1 )
