fread

 string fread ( resource $handle , int $length ) 

説明

fread() reads up to length bytes from the file pointer referenced by handle. Reading stops as soon as one of the following conditions is met: length bytes have been read EOF (end of file) is reached a packet becomes available or the socket timeout occurs (for network streams) if the stream is read buffered and it does not represent a plain file, at most one read of up to a number of bytes equal to the chunk size (usually 8192) is made; depending on the previously buffered data, the size of the returned data may be larger than the chunk size.

戻り値

Returns the read string or FALSE on failure.
