Perform Function on Each Item of an Array

array_map() takes two arguments. The first argument is the function to perform on the second argument (which is an array). Returns a new array.

$original = array('<p>Paragraph</p>', '<strong>Bold</strong>');
$new = array_map('strip_tags', $original);

// $new is now array('Paragraph', 'Bold');

    Nice one. Didn’t know about this function yet. Normally I would do a foreach loop.

  • Use Markdown, and it will escape the code for you, like `<div class="cool">`.
  • Use triple-backticks for blocks of code.
    ``` 
    <div>
      <h1>multi-line block of code</h1>
      <span>be cool yo.</span>
    </div>
    ```
  • Otherwise, escape your code, like <code>&lt;div class="cool"&gt;</code>. Markdown is just easier though.
