  51. <p>This library provides the ability to load pages through the PhantomJS 
    52. 

  52. headless browser and return the page response. It also lets you screen
    53. 

  53. capture pages and save the captures to disk. It is designed to meet a 
    54. 

  54. simple objective and does not offer a PHP API to the full suite of 
    55. 

  55. PhantomJS functionality.</p>
    56. 

  56. 

  57. <p>The PhantomJS executable comes bundled with the library. If installed
    58. 

  58. via composer, the file will be symlinked in your bin folder.</p>
    59. 

  59. 

  60. <p>If you are looking for a PHP library to run external javascript files 
    61. 

  61. through PhantomJS then this is not for you. Check out <a href="https://github.com/Dachande663/PHP-PhantomJS">PhantomJS runner</a>.</p>

  266. 

  267. <p>Version 2.0.0 changes the way requests are made. Requests now require you 
    268. 

  268. to inject a request and response instance into the send method. The examples 
    269. 

  269. above illustrate how to make requests in version 2.0.0 and will not work 
    270. 

  270. for older versions.</p>

    273. 

  273. <li>Requests now require you to inject a request and response instance when sending.</li>
    274. 

  274. <li>Added message factory that can also be injected into client when instantiated.</li>
    275. 

  275. <li>Custom headers can be set in requests.</li>
    276. 

  276. <li>Request method can be set. Supports: OPTIONS, GET, HEAD, POST, PUT, DELETE, PATCH.</li>
    277.
