I'm getting the dreaded "No input file specified" when I try to invoke PHP
from thttpd (nochroot).

I wrote a C program to dump environment variables before trying to invoke
PHP. I've included the dumped environment variables below.

As you notice in the C program, I've tried both "argv[0]" (i.e., I'm using
a hard link to the program from "script.php" to "phpexec") and the
SCRIPT_FILENAME variable. The version below is with SCRIPT_FILENAME. The
file name in question does exist and if I execute

$ /cgi-bin/php3 /mydomain.com/robert/archives/personal/script.php3

it works. (Note that /mydomain.com is a symbolic link to
/var/www/mydomain.com . I imagine that this doesn't matter since I'm
running thttpd with nochroot.)

I believe that execl() is supposed to pass the environment to the chained
program (php3 in this case).

Does anyone have any ideas how to fix this problem? I'm using PHP version
3.0.18 on a Sarge Debian GNU/Linux system.

Thanks.

fprintf(fp,"%s\n", environ[i++]);
}
// strcpy(name, argv[0]);
strcpy(name, getenv("SCRIPT_FILENAME"));
if ((p = strrchr(name, '.'))) {
strcpy(p, ".php3");
} else {
strcat(name, "3");
}
fprintf(fp, "%s\n", name);
fclose(fp);
execl("/cgi-bin/php3","php3",name,0);
}
