Workarounds

  1. 95% success Validate date strings before passing to DateTime: if (!strtotime($dateString)) { throw new InvalidArgumentException('Invalid date: ' . $dateString); } 
    Validate date strings before passing to DateTime: if (!strtotime($dateString)) { throw new InvalidArgumentException('Invalid date: ' . $dateString); }
  2. 90% success Use DateTime::createFromFormat() with explicit format string to control parsing: $date = DateTime::createFromFormat('Y-m-d H:i:s', $input); 
    Use DateTime::createFromFormat() with explicit format string to control parsing: $date = DateTime::createFromFormat('Y-m-d H:i:s', $input);

中文步骤

  1. Validate date strings before passing to DateTime: if (!strtotime($dateString)) { throw new InvalidArgumentException('Invalid date: ' . $dateString); }
  2. Use DateTime::createFromFormat() with explicit format string to control parsing: $date = DateTime::createFromFormat('Y-m-d H:i:s', $input);

Dead Ends

Common approaches that don't work:

  1. 70% fail

    Setting date.timezone in php.ini to an invalid value like 'UTC-8' instead of 'America/New_York' does not fix parsing but changes the error message.

  2. 90% fail

    Using @suppress or error_control operator (@) hides the exception but does not fix the underlying invalid date string, leading to silent data corruption.
