Run shell script from php and see complete progress?
Here is another approach. It uses redirection to output the results and then file_get_contents() to read the output.
<?phpecho "loaded<br><br>";$cmd = 'npm start';$run = $cmd . ' > result.txt 2> errors.txt';$output = shell_exec($run);$results = file_get_contents('result.txt');if (strlen(file_get_contents('errors.txt')) != 0) { $results .= file_get_contents('errors.txt');}echo "<pre>$results</pre>";?>
I guess, ob_flush() would work:
<?phpecho "loaded<br><br>";ob_flush(); // echo shell_exec("cd /var/www/html/..");// rin the shell scrip from header_register_callbackecho '<pre>';ob_flush();// Outputs all the result of shellcommand "ls", and returns// the last output line into $last_line. Stores the return value// of the shell command in $retval.$last_line = system('cd /var/www/html/; npm start', $retval);// Printing additional infoecho '</pre><hr />Last line of the output: ' . $last_line . '<hr />Return value: ' . $retval;?>But I don't understand why you echo HTML-tags when you run that script on the console... Hope I got you right
