1. Which version of PhantomJS are you using? Tip: run phantomjs --version. 2.1.3-dev-release

2. What steps will reproduce the problem?
   install phantomjs 2.1.3 as follows

sudo wget https://github.com/ariya/phantomjs/releases/download/2.1.3/phantomjs
sudo chmod +x ./phantomjs
sudo ln -sf /root/phantomjs /usr/local/bin
phantomjs --version

when running phantomjs 2.1.3 from the console it works perfect, but when I run pantomjs from PHP with shell_exec or exec it does not print anything I add 2> & 1 and it is printing me the following message.
sh: 1: phantomjs: Permission denied

3. Which operating system are you using? ubuntu 16.04 64bits

4. Please provide any additional information below.
   I used phantomjs 2.1.1 from php with the same command shell_exec and it worked perfect but currently 2.1.1 has a bug that did not execute some jquery and javascripts for this reason I was trying to try with 2.1.3 to see if this version does not have that bug.

please any help would be appreciated

Any plan for version > 2.1.1 is effectively abandoned. Please see #15344 for more details.
