fsockopen(): unable to connect to localhost and slow file_get_contents

[Phara0h]

Whenever I start a session before I call file_get_contents PHP crashes. It is not able to connect to any other site.

I am not able to use fsockopen to connect to my smtp either.

Using fsockopen to connect to smtp gives me:
Warning: fsockopen(): unable to connect to localhost:25

When running the example below I get the results both when I include the session_start AND not. But when including start_session the server uses 30 to 60 seconds to open the page. (When no session_start it uses 1 second)

Not including session_start() in the top of the examples makes the functions work.

My example for file_get_contents looks like this:

<?php
session_start();
$strContent = file_get_contents('

http://www.vg.no');

?>

I dunno what to say. When I run a modified version of your code:

<?php
session_start();
$strContent = file_get_contents('[URL unfurl="true"]http://www.vg.no');[/URL]
$fh = fopen ('test_foo.txt', 'w');
fputs ($fh, $strContent);
fclose($fh);
?>

the script finishes its runs in somewhere between 2 and 3 seconds and the file "test_foo.txt" contains the HTML of the specified site.

What version of PHP are you running on what platform?

I am running PHP 4.3.4

Your example here:

http://demo.siteman.no/sleipnir.php

Your example withouth session_start:

http://demo.siteman.no/sleipnir_nosess.php

I tried running phpinfo(); and it just loads and loads.

http://demo.siteman.no/phpinfo.php

When running the phpinfo.php from ssh with "php phpinfo.php" it works.

Seams there is a problem with my session module?

It's hard to say what the problem is. Have you tried running the session-enabled script via the command-line?

I can state for a fact that you are running a version of PHP that was released in November 2003. There have been an awful lot of improvements and bugfixes in the intervening 3 and a half years.

I'm not sure what's going on. When I use telnet on port 80 to fetch both pages, it takes forever before I even get a server response on the session-enabled page.


You've said you're running PHP 4.3.4, but your server says you're running 4.3.11. I assume you're getting your information from a phpinfo() script. I'm wondering if there's something wrong between your PHP installation and your web server.

This is what I get when running the session_enabled file from ssh.

# php sleipnir.php

Fatal error: Call to undefined function: session_start() in /

The techs working on my server yesterday swapped a .so file to upgrade the php-installation. My phpinfo

http://demo.siteman.no/phpinfo.txt

<-- I got this from cli since it does not work in web mode.

The phpinfo says 4.3.4 and it says in the configure line --disable-session ... I have a script using session, and session is working as it should..

The techs working on my server yesterday swapped a .so file to upgrade the php-installation.

It sounds to me like the techs broke something.

As a good general rule, I have never had success swapping out PHP .so files. Since I install by compiling the source tarball, I've always had to do an upgrade by compiling and installing the new version.

I am running SLES9, so compiling php is really not fun ... I am not really best at compiling.

But I have a viritual server on the same machine, so if I had some way of copying the os to the other viritual machine I could do a test upgrade on that one.

Do you know of a way of getting the whole os from one server to another?

That is not a PHP question. It should be asked in a more appropriate forum.


What about SLES 9 makes compiling PHP hard?

Well what I have run into earlyer is that I need to compile apache2 too in order to make the php a php-module.

I am really not that skilled in compiling php

 

[sleipnir214]

Yes, there can be lots of software which needs to be compiled and installed before PHP. But you've got odd errors and it sounds like someone's been tinkering.
