Pass parameter from php to casperjs/phantomjs

Question

Edit: I answered my own question, see edit below.

ORIGINAL: I have phantomjs and casperjs installed on my web server and they both run fine. The script I am planning

Answer 1

I found the answer myself.

It seems phantomjs and casperjs support command line arguments http://phantomjs.org/api/system/property/args.html

My script now looks like this.

test.php

$user_input = $_POST['user_input'];

putenv("PHANTOMJS_EXECUTABLE=/usr/local/bin/phantomjs");
exec('/usr/local/bin/casperjs hello.js $user_input 2>&1',$output);

print_r($output);

hello.js

var system = require('system');
var args = system.args;
var address = args[4]; //In my case 4 was the argument for $user_input, yours might be different, depending on your server setup.

var casper = require('casper').create({
  verbose: true,
  logLevel: 'error',
  pageSettings: {
    loadImages: false,
    loadPlugins: false
  }
});

casper.start(address, function() {
    this.echo(this.getTitle());
});

casper.run();
