Question

Is there a php.ini directive that enables stack traces on errors? I already looked here: http://php.net/manual/en/ini.core.php. My shared-hosting does not have Xdebug inst

There's debug_backtrace. This won't work for fatal errors though, since those cannot be handled.

Example:

gives:

array
  0 => 
    array
      'file' => string '/tmp/cpu7HL5A' (length=13)
      'line' => int 9
      'function' => string 'exceptions_error_handler' (length=24)
      'args' => 
        array
          0 => &int 8
          1 => &string 'Undefined variable: a' (length=21)
          2 => &string '/tmp/cpu7HL5A' (length=13)
          3 => &int 9
          4 => &
            array
              empty
  1 => 
    array
      'file' => string '/tmp/cpu7HL5A' (length=13)
      'line' => int 12
      'function' => string 'c' (length=1)
      'args' => 
        array
          empty
