Some things are implemented in PHP. Unfortunately the name is too short to be wiki-searchable, but try the What links here button. See also Software. A quick and easy way to see PSYC happen in PHP is by looking at the example code below, or by inspecting the Wikinotify tool.

Example application

Here is a generic notification code snippet for php applications which sends a notice to a PSYC place. 

<?php
    $myMsg = "This page has just been clicked.";
    $myApp = "Example";

    # information below is redundant, but parsing URIs is work
    $psyctarget = "psyc://localhost/@example";
    $psychost = "udp://localhost";
    $psycport = 4404;

    $udp = fsockopen($psychost, $psycport);
    fwrite($udp, ".\n"
       . ":_target\t$psyctarget\n"
       . "\n"     # move on from routing layer to application layer
       . ":_nick\t". $myApp ."\n"
       . ":_content\t". $myMsg ."\n"
       . "_notice_update_whatever\n"
         # always put dynamic data in variables, not into the body template
       . "[_nick] has been updated: [_content]\n"
       . ".\n");

    fclose($udp);
    return true;
?>

Here's suitable place.gen code to receive these notices. Put it into place/example.c, then /enter example. 

#define ALLOW_EXTERNAL_FROM "psyc://localhost"
#include <place.gen>

This code presumes you are running psyced on the same host with the php application. You need to replace those localhost references appropriately, if that is not the case.
