socket_read -- Reads a maximum of length bytes from a socket
Syntax
string socket_read ( resource socket, int length [, int type] )
The function socket_read() reads from the socket
resource socket created by the
socket_create() or
socket_accept() functions. The maximum number of bytes read
is specified by the length parameter. Otherwise
you can use \r, \n, or \0 to end reading
(depending on the type parameter, see below).
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.
Optional type parameter is a named constant:
PHP_BINARY_READ - use the system recv() function.
Safe for reading binary data. (Default in PHP >= 4.1.0)
PHP_NORMAL_READ - reading stops at \n or \r. (Default in PHP <= 4.0.6)
