Ubuntu – PHP cURL HTTP2 support

curlhttp2PHPUbuntu

I use Ubuntu 14.04.3 LTS on my server and run php5-fpm. I need to send a HTTP2 request via curl in php.

I used this tutorial to install curl/libcurl:
https://blog.cloudflare.com/tools-for-debugging-testing-and-using-http-2/

Somehow in terminal if I run 'curl –http2 https://….' everything works fine.

But if I try it in PHP nothing works. Also the php-info doesn't show the http2 support.

Maybe someone can help, thanks!

Your PHP is most likely linked to the system default libcurl.so, which does not support HTTP/2.

You need to find a PHP package for your system that is linked to use libcurl.so that supports HTTP/2.

Linux – NTLM with cURL returns 401

I am not really sure why, but while my 7.22 version shouldn't be affected by the whole NTLM issue, it seems that it is.

The only solution seems to be to use an old (<7.19, I tried with 7.15) version or to use a new version (I tried 7.26). As said, I cannot downgrade or upgrade libcurl itself just for this feature. This means we need to find a workaround....

Workaround used (warning: hack coming up)

Download and compile the curl you wish to use. I did NOT do this as root // sudo this because I don't want to replace the current libcurl etc!
```
wget http://curl.haxx.se/download/curl-7.26.0.zip
./configure --prefix=/local_path/
make
make install
```
Test the new curl command we just compiled: it does give the 401, but then instead of the gss_init_sec_context() you should see it going to an (in the end) 302. This is winning.
The hack part: use this libcurl when calling your script. We are working with a 3rd party PHP "app" (one of the reasons I'm not happy about changing all curl libs), and instead of directly calling this, we make an ugly-but-working wrapper, that calls something like this:
```
$se = shell_exec("LD_LIBRARY_PATH=/local_path/lib php /path/3rdparty.php");
```

Yes, this has drawbacks, and yes this is bit of a skeleton example (meaning you probably want to add some things like maybe the original path for instance) but the basics are kinda there.

Not really proud of this, but I think more people are restrained by the fact they cannot just go and update their libcurl to a random version and are using some sort of plugin that uses e.g. php-ews, or anything build on the NTLMSoapClient.

I hope there is another option down the line, but as this is currently the only way to get it 'working' I thought I'd share.

Nginx – Make PHP-FPM Listen at ‘IPAddress:Port’ Instead of ‘/var/run/php5-fpm.sock;’

I used $ sudo php5-fpm -t command to test if PHP-FPM's settings are fine (if not, it'll show me some error/info).

So, here's what the output looked like:

[13-Feb-2013 18:35:00] ERROR: [/etc/php5/fpm/pool.d/www.conf:33] value is NULL for a ZEND_INI_PARSER_ENTRY
[13-Feb-2013 18:35:00] ERROR: Unable to include /etc/php5/fpm/pool.d/www.conf from /etc/php5/fpm/php-fpm.conf at line 33
[13-Feb-2013 18:35:00] ERROR: failed to load configuration file '/etc/php5/fpm/php-fpm.conf'
[13-Feb-2013 18:35:00] ERROR: FPM initialization failed

The error says, something's wrong in Line 33 of of /etc/php5/fpm/pool.d/www.conf, which happens to be this: listen 127.0.0.1:9000 (not so much of a coincidence, is it?).

After seeing it, I immediately compared it with other lines, and then it struck me, an = (equal-to sign) is missing!

So, this is what it's supposed to be: listen = 127.0.0.1:9000 and that fixed everything!
