stream_select



les paramètres tv_sec et tv_usec forment le délai d'expiration, tv_sec spécifie le nombre de secondes tandis que tv_usec , le nombre de microsecondes. le paramètre timeout représente la limite supérieure du temps que stream_select() doit attendre avant de se terminer. si tv_sec et tv_usec sont tous les deux définis à ,  github is where people build software. more than million people use github to discover, fork, and contribute to over million projects. description. int stream_select ( resource &read, resource &write, resource &except, int tv_sec [, int tv_usec]). the stream_select() function accepts arrays of streams and waits for them to change status. its opperation is equivalent to that of the socket_select() function except in that it acts on streams. the streams listed in the

description. int stream_select ( array &read, array &write, array &except, int tv_sec [, int tv_usec] ). the stream_select() function accepts arrays of streams and waits for them to change status. its operation is equivalent to that of the socket_select() function except in that it acts on streams. the streams listed in the read array  mai you are creating a socket, therefore you need to use socket_select , not stream_select . the later is for file streams. you need to call socket_read to get any data from it. the php manual has some create examples in the comment section. also if you read the php manual about streamselect you will see this warning about using zero timeout: using a timeout value of allows you to instantaneously poll the status of the streams, however, it is not a good idea to use a timeout value in a loop as it will cause your script to consume too much

this line: stream_select($read, $write, $e = null, $timeout);. should be: $e=null; stream_select($read, $write, $e, $timeout);. while the first code will work, php will throw the e_strict message. i'm not sure why the php developers decided so. however, you should check the return type of stream_select() : on success stream_select() returns the number of stream resources contained in the modified arrays, which may be zero if the timeout expires before anything interesting happens. on error false is returned and a warning raised (this can happen if the system call is interrupted by an incoming signal). stream_select. (php >= ..). stream_select runs the equivalent of the select() system call on the given arrays of streams with a timeout specified by tv_sec and tv_usec  it's php v's new stream_select function that makes this possible. the requests are initiated in a conventional way by opening several stream_socket_client s and writing a get to each of them that corresponds to phaseit.net/demonstration/delay?delay=$delay . if you request this url yourself from
