(PHP 4 >= 4.1.0)

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

Description

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

Avertissement

Cette fonction est EXPERIMENTALE. Cela signifie que le comportement de cette fonction, son nom et concrètement, TOUT ce qui est documenté ici peut changer dans un futur proche, SANS PREAVIS! Soyez-en conscient, et utilisez cette fonction à vos risques et périls.

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:

  • 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)
