Return Values
socket_read() returns the data as a string on success,
or false on error (including if the remote host has closed the
connection). The error code can be retrieved with
socket_last_error(). This code may be passed to
socket_strerror() to get a textual representation of
the error.
Note:
socket_read() returns a zero length string ("")
when there is no more data to read.
