$sftp = new \phpseclib3\Net\SFTP('host', 22, 60);
$sftp->login('login', 'password');
$sftp->setTimeout(0);
$idx = 0;
do {
$sftp->exec('sleep 1; echo test;');
var_dump($idx);
$idx++;
} while ($idx < 60);
echo 'OK';Correct output in version 3.0.37:
int(0) int(1) int(2) int(3) int(4) int(5) int(6) int(7) int(8) int(9) int(10) int(11) int(12) int(13) int(14) int(15) int(16) int(17) int(18) int(19) int(20) int(21) int(22) int(23) int(24) int(25) int(26) int(27) int(28) int(29) int(30) int(31) int(32) int(33) int(34) int(35) int(36) int(37) int(38) int(39) int(40) int(41) int(42) int(43) int(44) int(45) int(46) int(47) int(48) int(49) int(50) int(51) int(52) int(53) int(54) int(55) int(56) int(57) int(58) int(59) OK
Maximum execution time exceeded throw in version 3.0.38 or 3.0.39:
int(0) int(1) int(2) int(3) int(4) int(5) int(6) int(7) int(8) int(9) int(10) int(11) int(12) int(13) int(14) int(15) int(16) int(17) int(18) int(19) int(20) int(21) int(22) int(23) int(24) int(25) int(26) int(27)
