使用exec（）从PHP运行PhantomJS

Question

I'm trying to execute PhantomJS via PHP on my local host (MAMP) on MacOS.

I've installed PhantomJS

$ sudo cp phantomjs-1.9.8-macosx/bin/phantomjs /usr/local/bin

and made the file executable

$ sudo chmod +x /usr/local/bin/phantomjs

When I go to the folder containing my file hello.js and on the command line type

$ phantomjs hello.js 

it works fine.

However, when I try it in PHP on index.php,

<?php
    $response = exec('/usr/local/bin/phantomjs hello.js');
    echo $response;
?>

I get nothing! What am I doing wrong? Any help is greatly appreciated.

Answer 1

<?php    
exec('/usr/local/bin/phantomjs path/hello.js');
?>

Yes. Sometimes phantomjs don't need full path in some environment without generate any error. However, sometimes it does.

Always use the full path for all argument in the php command.

Did you use the fullpath for hello.js?
