我正在寻找解析我从PHP shell_exec回来的输出。但是，返回的一些输出是表格格式，数据包含在列中，如下所示...

为了更容易解析，我希望能够改变输出的宽度，以便数据不会被包装。
我假设用stty指定控制台的宽度会起作用，但它没有。我试过这个......
$output = shell_exec('stty cols 180; cd /; cd ' . $drupal_sites_folder_path . $list_of_drupal_sites[22] . '; drush pm-updatestatus');
...但输出宽度仍然设置为80列。
有关如何更改shell_exec的输出宽度的任何建议？
