Tesseract exec not working

I have been trying to work this out for a couple days now and can’t crack it.

I’m trying to use php to echo the result of tesseract.

After everything I’ve researched and tried, I feel like the below code should work.

<?php

echo '<pre>';
echo exec('/usr/local/bin/tesseract /home/username/www/ocr/images/hello.png result');
echo '</pre>';

?>

The command runs fine via SSH and if I change the above to suit ifconfig it works fine.

Any ideas to get this working?

Answer

I ended up getting this working by just breaking everything down.

file_put_contents("$tmpFile",file_get_contents($img));
$cmd = "/usr/local/bin/tesseract $tmpFile stdout";
exec($cmd, $msg);
$arraymsg = $msg;
$msg = implode(' ', $msg);
echo $msg;
