This is an example of how to upload a file from PHP to another server that may or may not be running PHP.

Note that using Pear's HTTP_Request package is probably easier.

<?php
  require_once('Var_Dump.php');
  Var_Dump::displayInit(array('display_mode' => 'HTML4_Text'), array('mode' => 'normal','offset' => 4));

  $url = 'www.aktagon.com/upload';
  $file = '/tmp/file_to_upload';
  $post_data = array();

  $post_data['username'] = '';
  $post_data['password'] = '';
  $post_data['file'] = "@$file";

  $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array(
#    'Cookie: xxxx',
#    'Content-Type: xxxx'
  ));
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
  curl_setopt($ch, CURLOPT_POST, true);
  #curl_setopt($ch, CURLOPT_PROXY, '127.0.0.1:8888');

  curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);

  $response  = curl_exec($ch);
  $info      = curl_getinfo($ch); 
  $http_code = $info['http_code'];
  $speed     = round($info['speed_upload'] / 1024);
  $size      = round($info['size_upload'] / 1024);

  if($http_code != 200)
  {
    echo "Upload failed with HTTP code $http_code. Uploaded $size kilobytes with $speed kilobytes/s.<br/>";
    echo "<h1>Response</h1><pre>$response</pre><h1>Debug information</h1>";

    Var_Dump::display($info);
  }
  else
  {
    echo "Uploaded successful. Uploaded $size kilobytes with $speed kilobytes / s.<br/>";
    echo "<h1>Response</h1><pre>$response</pre>";
  }
  curl_close($ch);
?>

You can remove the Var_Dump code (Pear module), if you haven't installed it, or don't need it.

PHP file upload works in mysterious ways:

http://us3.php.net/manual/en/ini.core.php#ini.post-max-size
http://fi.php.net/manual/en/features.file-upload.php#73762
http://de3.php.net/manual/en/features.file-upload.errors.php

First you'll need to setup a UIWebView in for example Interface Builder. Then in the controller you add this incredible piece of code:

NSString *path = [[NSBundle mainBundle] pathForResource:@"about" ofType:@"html" inDirectory:@"html"];
NSLog(@"%@", path);
NSURL *url = [NSURL fileURLWithPath:path];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
[webView loadRequest:request];

This beautiful piece of code will look for a file named about.html in a folder called html. Now go create that folder and the file with your favorite tools.

Next drag that folder under your application in Groups & Files in XCode. Now to make XCode happy you have to make sure you select Create Folder References for any added folders.

That's it. If you get this error it means the file couldn't be found, and that you didn't import the files correctly:

Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '*** -[NSURL initFileURLWithPath:]: nil string parameter'

mix.exs:

  def application do
    [
      applications: [:logger, :logger_file_backend, ...],
      mod: {Snippets, []}
    ]
  end

  def deps do
    [
      {:cowboy, "~> 1.0.0"}, # web server
      {:logger_file_backend, "~> 0.0.7"} # writes log messages to a file, LOL
      ....
    ]
   end

config/dev.exs:

config :logger, :error_log,
  path: "log/app.log",
  level: :debug

find . -name "*.yaml" | xargs perl -p -i -e "s/foo/buzz/g"
find . -type f -name "*.yaml" -print0 | xargs -0 sed -i '' -e 's/foo/bar/g'

I recommend installing and using repren if you need a simpler solution: https://github.com/jlevy/repren
