[RESOLVED] Not able to read http response , file()

petterween

Hi,
Need some advise on this one;

Running FC5 with and yumed with latest updates.

I'm trying to read HTTP respons as file, using func file().

Tried example from Manual, and others.

I can read local text file, but when changing aredress to http://localhost/ , it doesnt work.

Tried fopen() as well, without any luck.

the variable: allow_url_fopen , in PHP.INI says On.

All suggestions are very appreciated.

Regards
Petter

What happens when you try it on an external domain, like "file('http://google.com');"?

Hi,

I have tried;

$lines = file('text.txt'); // Works fine !

$lines = file('http://google.com/') // This does not work :-(

Read the PHP Manual on Using remote files.

Hi,
I've read the links.. and more,more,more
But still faulty... hmm..

This is probably some simple config, but I cant figure it out..

Turned E_ALL on in PHP.INI
This is with just one command line:

<?php
$lines = file('http://google.com'); //line 2
?>

Browser output:

Warning: file(http://google.com) [function.file]: failed to open stream: Permission denied in /var/www/html/tt1.php on line 2

This line gives the same result:
$httpfile = fopen("http://google.com/", "r");

Same result if URL is localhost.

print_r(stream_get_wrappers());

Array ( [0] => php [1] => file [2] => http [3] => ftp [4] => compress.bzip2 [5] => compress.zlib [6] => https [7] => ftps )

PHP.INI
allow_url_fopen On
open_basedir no value

safe_mode Off

Any Ideas what causes the 'Permission denied'??
I'm sure its simple, but can't see it :-(

Didnt you read what I linked to? The reason is that allow_url_fopen is not enabled in php.ini

petterween

So what you are saying is that

allow_url_fopen On means that its not enabled ???

That fools me, I would say that 1 (ON) in common sence would be equal to allow in this statement, and Off (0) would = deny. If this parameter has to be off to allow ,this parameter should be renamed deny_url_open instead.

well , I'll try setting the parameter to off, And see whats happening.

thanks for help !

Setting this to Off is not a solution!
This is reported error when setting allow_url_fopen to Off:

Warning: fopen() [function.fopen]: URL file-access is disabled in the server configuration in /var/www/html/tt4.php on line 2

Warning: fopen(http://google.com/) [function.fopen]: failed to open stream: no suitable wrapper could be found in /var/www/html/tt4.php on line 2

Sorry, my mistake, I didnt see the last portion.

In this case, I suggest that you check other factors like firewalls that could be blocking an outgoing connection.

petterween

Yes, I wondered if it could be a firewall problem, but shouldn't it work well as regular http requests works fine??
Since it is just piping regular http??
If this function uses some "irregular" 'http' conversation, this should be clearly notified some place.
If so I think this coding of the function is no good. You should be able to use regular ports when piping stream from http,ftp, etc.

Or not ??

Hi,
Yes,, It was 'simple' !

Running FC5.
'Regular' Firewall settings shouldn't cause any trouble when using file().
But..SELinux in FC5 did!

When SELinux is not disabled, 'Enforcing/Permissive, then you have to make some changes in the 'SELinux Policy'

You must either disable SELinux entirely, or in the 'SELinux Policy', check the unchecked box: "Allow HTTPD scripts and modules to connect to the network"

This makes File('http://.....) work !! :-)

KDE
Administration->Security Level and Firewall-> SELinux->Modify SELinux Policy->HTTPD Service-> Allow HTTPD scripts and modules to connect to the network.

There might be some notice about this, even though I couldn't find it (!). If not I think someone should do so. Even if the solution was 'obviously easy'.

Regards
Petter.

So did that get your problem resolved? If so, don't forget to mark the thread resolved.

Hmmm, is that a coincidence that you found the answer 20 minutes after i posted what the problem probably was in this other post by yourself? It could be.

Hi Samudasu ,
Yes, It's a funny coincidence!!, but thanks for your answere! I havent followed up that thread in the install forum, and didn't see it before you told me now. When I first posted this problem , I posted it in the Install forum. But since no one seemed to come up with some ideas, I tried to post it in an another relevant forum with much higher activity. And as you see by yourself, you're the first one to respond to the thread in the Install forum, AFTER 3 DAYS !!.. So I considered that forum for this question as dead.

Yes, I know FC is the "beta product" for RH server products. Used Slackware else, but had some problems with that releases from time to time as well, so I'd guess the different distros has its own "problems" pro/cons with them all. And sometimes you want a server solution stripped from all unessessary stuff, sometimes you would like the hole package for you convenience.

Thanks all.
(might come up with another problem soon)

Regards Petter
