title: curl functions are not working in php5.6
body: <p>I'm Developing an application that uses curl scripts, and i have 2 versions of php (php 7.0 and php 5.6) in my ubuntu 16.04 computer. for php7.0 i have installed curl by issuing </p>
  
  <pre><code>sudo apt-get install php-curl
  </code></pre>
  
  <p>i was successful and i used curl when i'm using php7.0. but for some reasons i had to switch to php5.6. for that version of php the curl functions are not working. then after few google searches i found an answer and i tried to install curl for php5 bu issuing the below command.</p>
  
  <pre><code>sudo apt-get install php5-curl
  </code></pre>
  
  <p>it prompted a warning says that php5-curl package is not found. then i found there is an another package <code>php5.5-curl</code>, i installed that, still i don't get the curl working in php5.6.</p>
