How to disable PHP cutting off parts of long arguments in exception stack trace?

Question

Sometimes things like this happen:

#0 /some/path(1): Class_Name->exception_trigger()
#1 /some/other/path(5):  get_to(\'/some/long/path/tha...\')


        

Answer 1

You'll have to replace the uncaught exception handler. Example:

function exception_handler($exception) {
    $i = 0;
    foreach ($exception->getTrace() as $frame) {
        echo sprintf("#%d %s(%d): %s(%s)\n",
            $i++, $frame["file"], $frame["line"],
            $frame["function"],
            implode(", ", array_map(
                function ($e) { return var_export($e, true); }, $frame["args"])));
    }
}

set_exception_handler('exception_handler');

Now you'll get something like:

#0 /home/glopes/a.php(21): a('loooooooooooooooooooooooooooooooooong argument')
#1 /home/glopes/a.php(24): b()

Answer 2

If you're using xdebug you can specify the length and number of variables it spits out.
