Github Extract Commit, Contributors and Issues data with PHP, the awful way

github_repo_data.php

<?php  
  function getGithubData($user,$repo){
    $ch = curl_init();
    $url = 'https://api.github.com/repos/'.$user.'/'.$repo.'/commits';
    $url2 = 'https://api.github.com/repos/'.$user.'/'.$repo.'/stats/contributors';
    $url3 = 'https://api.github.com/repos/'.$user.'/'.$repo.'/issues';
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_HEADER, FALSE); 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('User-Agent: Awesome-Octocat-App')); 
    $head = curl_exec($ch); 
    $data['commits']= sizeof(json_decode($head));
    curl_setopt($ch, CURLOPT_URL, $url2); 
    $head = curl_exec($ch); 
    $data['contributors'] = sizeof(json_decode($head));
    curl_setopt($ch, CURLOPT_URL, $url3); 
    $head = curl_exec($ch); 
    $data['issues'] = sizeof(json_decode($head));
    return $data;
    curl_close($ch); 
  };
