Shitty PHP

examples.php

<?

/*
  PHP takes the design of Perl (ugly), the interfaces
  of C (low-level and clunky), and the OO of C++ 
  (an impure mess). Some things are completely broken,
  and every API is either inconsistent or just 
  inconvenient.

  Its only utility is its output of inline text, which
  is convenient for mostly-text websites with some functionality,
  but terrible for well-designed programs, interweaving
  functionality and views at a fundamental level.
*/

// Completely Broken Things
// ========================

/*
  When an undefined variable is passed as argument to
  a function, it is instantiated. Even worse, when an
  accessor on an undefined object is passed, it too is
  instantiated.
*/
function undefined_ref_is_instantiated_with_key(&$a) {}
undefined_ref_is_instantiated_with_key($x['foo']);
// => $x = { foo => NULL }

/*
  When an array with a string that looks like a number
  is checked for the presence of another string, one
  looking like an equivalent number, it is "found".
*/
function string_is_found_present_when_numbers_are_equal() {
  $arr = array('7.1');
  $found = in_array('7.10', $arr);
  // => $found = true
}

// Terrible Design
// ===============

function inconsistent_names() {
  base64_encode("");
  urlencode("");

  deg2rad(12);
  strtotime("10:30");

  // These are inverses!
  $encoded = htmlentities("<abc>");
  html_entity_decode($encoded);
}

  array_filter($callback, $arr);
  array_map($arr, $callback);
