PHP命令行和服务器之间的区别

Question

If I run

php -r 'print_r(file_get_contents("http://mirror.facebook.net/centos/timestamp.txt"));'

I get "Tue Oct 28 13:24:01 UTC 2014" (as expected).

But if I have a php file:

<?php
print_r(file_get_contents("http://mirror.facebook.net/centos/timestamp.txt"));

It gives me:

**Warning:** file_get_contents(): php_network_getaddresses: getaddrinfo failed: Name or service not known ...

**Warning:** file_get_contents(http://mirror.facebook.net/centos/timestamp.txt): failed to open stream: php_network_getaddresses: getaddrinfo failed: Name or service not known ...

What is the difference between "php -r" and php running the code out of a file

UPDATE

This is not the answer to the question but it did solve my problem so for the sake of future googlers: I don't know which of these two solutions was the key but it was working when I restarted apache.

1. In resolv.conf set nameserver 8.8.8.8 (which had my router's address)

2. There's an SELinux boolean httpd_can_network_connect which must be turned on:

setsebool -P httpd_can_network_connect 1

See this solution and this one.

Answer 1

Your PHP CLI is using a different php.ini (or maybe no php.ini at all). It's also possible you are running a completely different PHP binary than what your server is using.

You can run php -i on the command line, and phpinfo() in a script to determine which php.ini is in use.
