输出缓冲区错误处理

Let us assume that an easy snippet is used for templating and is using output control (ob)

public function capture($file, array $args = array())
{
    extract($args, EXTR_SKIP);

    ob_start();

    require $file; //'foo.php'

    return ob_get_clean();
}

And foo.php that has an error (handled by an error handler and shutdown handler)

<?php

echo "before";
echo $someVariable; //$someVariable is undefined here
echo "after";

Output

before <- would like to avoid
some message from the error handler

The question: is it possible to avoid any output from the file upon error?

Yes,

• there are similar questions out there that I read/analysed but none of them gave me a clear answer whether this is or isn't.

• I understand that you should not want to handle this kind of errors in your own code since it has to be clean & tested but still you might get some, e.g. typo, undefined variable, etc.
