Parameters

Optional type parameter is a named constant:

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.
