Just make sure you enabled '.htaccess' to overwrite your php settings. This invalidates to use ini_set():ģ) Still fails?. You can see that the 'upload_max_filesize', among others, is PHP_INI_PERDIR and not PHP_INI_ALL. In our case a large upload could take 1 or 2 hours.Īdditionally we had 'session settings' that should be preserved after upload.ġ) You might want review those ini entries:Ģ) Still fails? Caution, not all are changeable from the script itself. It may happen that your outgoing connection to the server is slow, and it may timeout not the 'execution time' but the 'input time', which for example in our system defaulted to 60s. If 'large files' (ie: 50 or 100 MB) fail, check this: If you have to check the size of a file, do it conventionally within your script, using a script-defined integer, not an arbitrary number you got from the HTTP client (which always must be mistrusted from a security standpoint). A form field can easily be changed by the client. Please note that using this PHP feature is not a good idea. The PHP documentation implies that a browser may alert the user that his upload is too big - this is simply wrong. Up til today there has never been a RFC proposing the usage of such named form field, nor has there been a browser actually checking its existance or content, or preventing anything. This, however, is not true and has never been. The PHP documentation also makes (or made - see bug #40387 - ) vague references to 'allows browsers to check the file size before uploading'. If the uploaded file is bigger than the integer in this field, PHP disallows this upload and presents an error code in the $_FILES-Array. It checks the existance of a form field names 'max_file_size' (upper case is also OK), which should contain an integer with the maximum number of bytes allowed. In addition to this PHP somehow got implemented a soft limit feature. The two widely known limits are the php.ini settings 'post_max_size' and 'upload_max_size', which in combination impose a hard limit on the maximum amount of data that can be received. PHP has the somewhat strange feature of checking multiple 'maximum file sizes'. Throw new RuntimeException ( 'Failed to move uploaded file.' ) Ĭlarification on the MAX_FILE_SIZE hidden form field: On this example, obtain safe unique name from its binary data. DO NOT USE $_FILES WITHOUT ANY VALIDATION !! Throw new RuntimeException ( 'Invalid file format.' ) $finfo = new finfo ( FILEINFO_MIME_TYPE ) Throw new RuntimeException ( 'Exceeded filesize limit.' ) The following code cannot cause any errors absolutely. You'd better check $_FILES structure and values throughly.
