socket_read Reads a maximum of length bytes from a socket stringsocket_read resourcesocket intlength inttype &warn.experimental.func; 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. 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: PHP_BINARY_READ - use the system read() 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) See also socket_accept, socket_bind, socket_connect, socket_listen, socket_last_error, socket_strerror and socket_write.
