Hi!

Faced one problem, if I execute a php script from a cgi script, recursion occurs.

Tests it programm:

# Create PHP CLI script:
echo '<?php echo date("H:i:s")." $argv[0]\n"; ?>' > /tmp/cli.php

# Test it:
/usr/bin/php-cgi -q /tmp/cli.php

# Create PHP WEB script (choose one of the following):
echo '<?php passthru("/usr/bin/php-cgi -q /tmp/cli.php >> /tmp/cli.log");echo date("H:i:s")." web.php\n";?>' > /www/web.php
echo '<?php exec("/usr/bin/php-cgi -q /tmp/cli.php >> /tmp/cli.log",$a);echo date("H:i:s")." web.php\n";print_r($a);?>' > /www/web.php
echo '<?php system("/usr/bin/php-cgi -q /tmp/cli.php >> /tmp/cli.log");echo date("H:i:s")." web.php\n";?>' > /www/web.php
echo '<?php echo date("H:i:s")." web.php\n" . shell_exec("/usr/bin/php-cgi -q /tmp/cli.php >> /tmp/cli.log");?>' > /www/web.php

# Clear log file:
rm -f > /tmp/cli.log

# Test WEB script:
/usr/bin/php-cgi -q /www/web.php

# Show log file:
cat /tmp/cli.log

# Clear log file:
rm -f > /tmp/cli.log

# Exec show count script:
while [ y ];do p=`ps`;c=`echo "$p"|grep -c "cli.php"`;w=`echo "$p"|grep -c "web.php"`;date "+%H:%M:%S cli=$c web=$w";sleep 1;done

# Next terminal exec download WEB page script:
time wget -O - http://127.0.0.1/web.php

# Next terminal show runing process:
ps | grep -v grep | grep "web.php\|cli.php"

Test results (100% repeatability):

Any help is appreciated :slight_smile:

That command doesn't do what you think it does.

I'm not sure about the PHP part, but unless it's evident that it's an OpenWrt-specific issue, not only you are far likely to get better help on places like PHP-specific stackexchange/reddit sections, this thread probably doesn't even belong here.

The initial version of the command was like this:

# Clear log file:
echo -n > /tmp/cli.log

The initial program actually modifies the configuration files and stops / starts programs, so we elevate the privileges to root:

grep [rp]name /etc/lighttpd/lighttpd.conf 
#server.username             = "http"
#server.groupname            = "www-data"

grep user /etc/init.d/lighttpd
#	user_exists http || user_add http

But I don't think anyone will go into the details of the privileges, so I replaced the command with a different one. Just not being attentive, sorry. Real programs are also different from these one-line scripts.

But this does not change the essence of the problem.

The problem was solved by replacing the CGI method with FastCGI:

grep cgi /etc/lighttpd/lighttpd.conf 
static-file.exclude-extensions = ( ".php", ".pl", ".fcgi" )
#cgi.assign = (".php" => "/usr/bin/php-cgi")
fastcgi.server = (".php" => ("php-tcp" => ("host" => "127.0.0.1","port" => 1026,"check-local" => "disable","broken-scriptfilename" => "enable")))

But this is not a solution to the problem, this is a workaround.
