PHP中的shell_exec（）

Question

<?php
  // Execute a shell script
  $dump = shell_exec('bigfile.sh'); // This script takes some 10s to complete execution
  print_r($dump); // Dump log to screen
?>

When the script above is executed from the browser, it loads for 10s and the dumps the output of the script to the screen. This is, of course, normal. But if I want the data written to STDOUT by the shell script to be displayed on the screen in real-time, is there some way I could do it?

Answer 1

我将添加proc_open（），如果需要的话，它可以使您对命令执行有更多的控制，如果不尝试的话，可以尝试通过前面提到的passthru（）或popen（）。

Answer 2

Try this:

$handle = proc_open('bigfile.sh', array(0 => STDIN, 1 => STDOUT, 2 => STDERR), $pipes);
$status = proc_close($handle);

It works great for me.

Answer 3

Try passthru() or popen()

The code will look something like this:

<?php 
        $fp=popen("bigfile.sh","r");
        while (!feof($fp)) { 
                $results = fgets($fp, 256); 
                echo $result; 
                flush(); 
        } 
?> 

As @wik suggest below you can also try proc_open instead of popen it should work in a similar fashion.
