Varovanie

Táto funkcia je EXPERIMENTÁLNA. Správanie tejto funkcie, názov tejto funkcie a hocičo iné zdokumentované o tejto funkcii sa môže zmeniť bez povšimnutia v budúcom vydaní PHP. Používajte túto funkcii na svoje vlastné riziko.

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.

Poznámka: 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:
