freadBinary-safe file readDescriptionstringfreadresourcehandleintlengthfread reads up to
length bytes from the file pointer
referenced by handle. Reading stops when
length bytes have been read, EOF
(end of file) is reached, or (for network streams) when a
packet becomes available, whichever comes first.
]]>
On systems which differentiate between binary and text files
(i.e. Windows) the file must be opened with 'b' included in
fopen mode parameter.
]]>
When reading from network streams or pipes, such as those returned when
reading remote files or from
popen and fsockopen, reading
will stop after a packet is available. This means that you should
collect the data together in chunks as shown in the example below.
]]>
If you just want to get the contents of a file into a string, use
file_get_contents as it has much better performance
than the code above.
