PHP Version: 4.0.6
New Comment:
php does not require a local dns server to be running unless your system's C library
gethostbyname() call does (which seems extraordinarily unlikely).
here's a small c program you can use to test your system's gethostbyname(). if it says
that no ip address is found, that's the exact same situation in which php's
gethostbyname() will return the original hostname.
#include <stdlib.h>
#include <stdio.h>
#include <netdb.h>
#include <sys/socket.h>
#include <netinet/in.h>
#include <arpa/inet.h>
int main(int argc, char **argv) {
struct hostent *host;
struct in_addr in;
if (argc != 2) {
fprintf(stderr,"usage: %s hostname\n", argv[0]);
exit(1);
}
host = gethostbyname(argv[1]);
if (host->h_length) {
memcpy(&in.s_addr, *(host->h_addr_list), sizeof(in.s_addr));
fprintf(stderr,"%s\n",inet_ntoa(in));
}
else {
fprintf(stderr,"no ip address found for %s\n", argv[1]);
exit(1);
}
exit(0);
}

Does PHP require a local bind running? Everything seems to point in that direction.
The resolver libs are doing a lookup to the address of 0.0.0.0 vs. the servers as
configured in resolv.conf.
;; Querying server (# 1) address = 0.0.0.0

IMHO this is not the same as #13423, which is why I didn't list it in the original
report. Although the data returned is the same (hostname instead of IP address) the
reason for the failure is seems very different.

duplicate of 13423, among the others listed in the report. gethostbyname() returns the
hostname it is passed when the C-level gethostbyname() call fails.

This is basically the same report as 8754, 12678, and 8856. The gethostbyname
function returns the name instead of the IP address. The host is configured correctly
and names can be resolved from the shell using nslookup, dig, etc. This bug first
appeared in 4.0.4 (although I didn't know it until now) and is present in 4.0.6 and
4.0.8-dev (php4-200109251335.tar.gz - latest from the snapshots dir as of 9/26/01). I
regressed the bug back to my previous version of 3.0.14 and the bug is not present in
that version. I have tried both gethostbyname (returns the name) and gethostbynamel
(returns 0 items in the array).
