socket_read -- Reads a maximum of length bytes from a socket

Description

string socket_read ( resource socket, int length [, int type])

Warning

This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change without notice in a future release of PHP. Use this function at your own risk.

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. 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() may return a zero length string ("") indicating the end of communication (i.e. the remote end point has closed the connection).

Optional type parameter is a named constant:
