-

i have installed tesseractocr terminal of mac. when run following command terminal working.

tesseract "hello.png" /applications/mamp/tmp/php/987051047

but same command not working in

exec("tesseract "hello.png" /applications/mamp/tmp/php/987051047")

and full code 

$tesseract = new tesseractocr("hello.png");  $tmp_dir = ini_get('upload_tmp_dir') ? ini_get('upload_tmp_dir') : sys_get_temp_dir();  $tesseract->settempdir( $tmp_dir );  $test =  $tesseract->recognize();

i feel have load tesseract in php.ini or other configuration file. don't know where. using mac, mamp, php 5.4.10

ok after installation need change path bin

$path = getenv('path'); putenv("path=$path:/usr/local/bin");
