Returns the size of the file in bytes, or &false; (and generates an error
|
|
of level <constant>E_WARNING</constant>) in case of an error.

|
Because PHP's integer type is signed and many platforms use 32bit integers,
|
|
<function>filesize</function> may return unexpected results for files which
|
|
are larger than 2GB. For files between 2GB and 4GB in size this can usually
|
|
be overcome by using <literal>sprintf("%u", filesize($file))</literal>.
