php - Doctrine ODM Calling ->toArray on a Cursor causes CLI script called by exec to do a void return (only on exec/shell_exec call)

Question

I use a CLI script to do some stuff. Today i want to adapte it to show me results on my browser rather than on temrinal. It works everytime perfectly when called called from terminal but not when i call it from exec php command WHEN there is a call on the doctrine Cursor::toArray. See bellow :

it executes the following lines of code :

        $parses=$dm->createQueryBuilder("App\Document\Parse")
                ->field('positions.website')->equals($name)
                ->getQuery()->execute();
        /* @var $parses Doctrine\ODM\MongoDB\Cursor */

        $details=[];




        foreach($parses as $parse){

            /* some other things */
        }


        echo json_encode($details);

when called form terminal (php cli.php find parses -site test.com) it return me a nice json document.

But now I want to show it on a browser. Then i do a little script (http accessable) calling 'exec("php cli.php find parses -site test.com")' . And it returns me nothing. (also tryed shell_exec ; also tryed with other scripts : they work)

Now i delete the foreach loop. I got the following code :

        $parses=$dm->createQueryBuilder("App\Document\Parse")
                ->field('positions.website')->equals($name)
                ->getQuery()->execute();
        /* @var $parses Doctrine\ODM\MongoDB\Cursor */

        $details=[];

        echo json_encode($details);

When i call it from exec : it returns me a nice empty json string

(Remember that each case still works when i call it directly from terminal)

Now i try to call ->toArray() on the doctrine cursor :

        $parses=$dm->createQueryBuilder("App\Document\Parse")
                ->field('positions.website')->equals($name)
                ->getQuery()->execute();
        /* @var $parses Doctrine\ODM\MongoDB\Cursor */

        $details=[];

        $parses->toArray();

        echo json_encode($details);

It returns nothing when i call it from exec or shell exec, but it returns a well "array(0) {}" when called from terminal itself.

It tryed other script with exec and shell exec, they all work and do good return, only when they dont use Doctrine cursor toArray

当您从终端运行 PHP 脚本时，它会在运行用户的许可下运行。当您在 Web 服务器上运行 PHP 脚本时，它会以服务器进程的权限运行。

检查运行脚本的用户是否有权访问 Web 目录中与运行服务器的用户相同的文件。

另外，您是否打开error_reporting并检查了error_log文件？
