(PHP 4 >= 4.0.7, PHP 5)
socket_read — Reads a maximum of length bytes from a socket
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).
Optional type parameter is a named constant:
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.
|4.1.0||The default value for type was changed from PHP_NORMAL_READ to PHP_BINARY_READ|
