I'm trying to make a JSON call library. It has the following features.
be able to customize the header
be able to POST any data to server(including form-encoding (a=1&b=2&c=3) and JSON data chunk)
parse the response and return as a JSON object
I searched in other questions and found that there are only two answers.
use file_get_contents(). This way is pretty simple and easy to use; however, you cannot do anything more than get the content -- you cannot add headers, cannot use POST. But it is usually supported by all servers.
use curl. This way seems powerful and you can do nearly everything with it. The disadvantage is that you have to install libcurl and php-curl support on your server, which means you may not use it on servers that have no curl installed.
So, if I want to develop a common library that can be used on most server, is curl a good choice?
Is there any other ways to do this?
In a short word, I'm looking for a PHP version of urllib2 in python - easy to use, powerful, and reliable.
You have two options: curl and HTTP stream context options. Both can accomplish what you have described; curl might not be installed everywhere, while stream contexts are a core feature and are always available.
Actually, you can also implement your library using sockets, which would be more work but will probably allow you greater control if you need to do weirder things with your requests.
As i know, curl is included in mostly on many server, since it supported from 4.0.2 PHP version natively.
Also there is a native php function header, which customizes your response's headers by simply using like this -> header('location: index.php'), header('cache-control: ok') and so on. You can view Network Functions section on php.net

Googling I've found this article:
http://java.dzone.com/tips/generating-client-java-code
It talk about how to generate a "JAVA" code with SOAP UI client, but what I need is to generate code php with soap UI or other resource.
Is this possible? exist any other resource to make it work that?
thank you for your answers..
Regards.
soapUI will not generate PHP code.
Fortunately, in PHP there often isn't a need to generate proxy classes. Instead, use SoapClient and simply call the SOAP methods you need outright. You can find simple examples at various blogs.
If the service with which you're interacting uses lots of complex types, then you may indeed want to auto-generate some PHP code and make use of SoapClient's classmap option.
I'm desperately searching for a way to generate SNMP traps from PHP. I know the build in methods to use snmpget but I was not able to figure out how to send SNMP traps.
Does anybody know a class / code snippet for it? Searching the web did not bring up anything other than using exec to call cli tools which is definately no option for me.
I suspect that it would be neccessary to use socket_create and corresponding functionality to generate the UDP package manually...
As far as I know, there is no native way for generating traps/informs with php. Even the SNMP extension only permits get and set requests. So the only (quick) way to accomplish this is to call an external tool like net-snmp. The proper command line would be something like
snmptrap -v 1 -c public manager enterprises.spider test-hub 3 0 '' interfaces.iftable.ifentry.ifindex.1 i 1
will send a generic linkUp trap to manager, for interface 1 (taken from the manpage). To execute this from php the net-snmp binaries should be on the path of the system and you could either call exec, shell_exec or proc_open.
Obvisouly you also can send the trap by yourself by encoding it as raw byte array and sending it over an UDP socket, but then you had to implement a BER encoder and a SNMP packet encoder all by yourself which I don't recommend. For your reference, you would need those informations:
Basic Encoding Rules
ASN.1
and some further links found
here
There are no core SNMP trap libraries. Or even any core libraries that will help you package an SNMP udp packet. I did however find this abandoned project. http://code.google.com/p/php-snmp/ which provides most of what you would need to send a simple trap.
A little more active but a lot more complex seems to be http://www.activexperts.com/network-component/howto/snmpts/php/
For anybody searching for such a library these days (in 2019), I found https://github.com/FreeDSx/SNMP which supports sending SNMPv1 and SNMPv2 traps (including inform requests).
I know this question is old, but I just came across it via Google, and thought to update it according to my findings in case someone else also lands here.
As Jek answered, using net-snmp is the best solution.
Although the original post said that he didn't want to use any external components, consider you can now add net-snmp though apt-get (look up package php-snmp) for many Linux distro's, and I'm sure installing on Windows will be equally easy.
The great benefit of using it, is as of PHP 5.3.3, PHP inherintly has built-in interface functions to use SNMP, so that you don't have to use exec, shell_exec or proc_open. Everything can be done in a PHP environment.
See http://php.net/manual/en/book.snmp.php
In regards to Can a PHP Proxy call Javascript functions like a click I'm investigating a solution that involves using PHP's HTTP class to simulate a client's browser.
Does anyone know if the PHP HTTP class supports javascript functions? Can you recommend any others that do?
Thanks!
No, it does not. You have to implement this yourself. If you want to have it all-serverside, look into phpjs, j4p5 or better yet the spidermonkey pecl extension. http://pecl.php.net/package/spidermonkey
A better alternative might be to script a real browser yourself via an XPI plugin / XPCOM bridge. There once was an extension called "JSSh", and another "SD connector", http://www.activestate.com/blog/2008/05/jssh-replacement-sd-connector
Neither of these options is simple. That's why nobody has done it, and why such extravagant features are specifically not in the HTTP class.
An Http stream handler is not in any way related to a browser. It will not generate a DOM tree, block ads or execute javascript - it is just a library handling the http protocol.
I am trying to proxy through php for a JS RSS feed. The company I am doing this for may or may not want cURL installed. If that is the case I may need some sort of library that can simply be included in php rather than go through apache and all of that. Is there a library that can handle something like that? What other options do I have in this case?
Thanks!
Zend_HTTP provides a wrapper for fopen, file_get_contents and CURL out of the box, it makes it much more simpler to store / read cookies, make POST requests and so on.
wget, fopen, and file_get_contents are other options you can use to use for a proxy.
For years, I've been investigating how to create music streams from my computer. I've seen programs, but anything useful I've seen is Windows only (I use a Mac).
Eventually, I got interested in how streams work. Is there any way I could create my own stream, possibly using socket functions in PHP? Is there a PHP library for this?
Take a look at Ampache. It is a Web-based Open Source Audio file manager. It is implemented with MySQL, and PHP. It allows you to view, edit, and play your audio files via the web.
In the end it all boils down to the protocol you'd want to use. Shoutcast IMHO is plain HTTP, so to make your own stream, you just output the streams content.
To make an ogg based webradio work with my Sonos system, I have created a little transcoding wrapper around sox which is is actually written in PHP, so it may be helpful to you to serve as an example.
You'll find it here: http://www.gnegg.ch/ogg2mp3/
If you are after implementing your very own streaming protocol - maybe even UDP based, then, I'm afraid, PHP may not be the right solution for the problem - at least not as long as it has its share of problems when used for long running processes (which 5.3 may bring some help for with its integrated garbage collection)
