Calling other function in the same controller?

Question

I've this controller, and the function read($q) return error Call to undefined function sendRequest()

<?php  class InstagramController extends BaseController {  /* |-------------------------------------------------------------------------- | Default Home Controller |-------------------------------------------------------------------------- | | You may wish to use controllers instead of, or in addition to, Closure | based routes. That's great! Here is an example controller method to | get you started. To route to this controller, just add the route: | |   Route::get('/', 'HomeController@showWelcome'); | */  public function read($q) {     $client_id = 'ea7bee895ef34ed08eacad639f515897';      $uri = 'https://api.instagram.com/v1/tags/'.$q.'/media/recent?client_id='.$client_id;     return sendRequest($uri); }  public function sendRequest($uri){     $curl = curl_init($uri);     curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);     curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 0);     curl_setopt($curl, CURLOPT_SSL_VERIFYHOST, 0);     $response = curl_exec($curl);     curl_close($curl);     return $response; }  } 

I'm assuming it's because I'm referencing the function in the wrong manner, but I can't find any explanations for how to do it.

Answer 1

Try:

return $this->sendRequest($uri); 

Since PHP is not a pure Object-Orieneted language, it interprets sendRequest() as an attempt to invoke a globally defined function (just like nl2br() for example), but since your function is part of a class ('InstagramController'), you need to use $this to point the interpreter in the right direction.

Answer 2

Yes. Problem is in wrong notation. Use:

$this->sendRequest($uri) 

Instead. Or

self::staticMethod() 

for static methods. Also read this for getting idea of OOP - http://www.php.net/manual/en/language.oop5.basic.php
