this question has answer here: how write php ternary operator 8 answers ok below information works im trying figure problem if displays title grade... but want put | inbetween this title | grade. my below code works if there no grade still echos |, how can echo when there value in field. because when field empty shows title | <div class="sto-info"> <span><?php echo $title; ?> <?php echo '|', $grade; ?></span> </div> you can use ternary operator: <span><?php echo $title; ?> <?php echo $grade ? '|' . $grade : ''; ?></span>

i have installed mosquitto on windows machine , it's mqtt v3.1 broker (downloaded mosquitto.org). i trying connect broker esp8266 , far have not been able connect broker. can connect public broker, not broker installed on machine connected same wifi network. i have built firmware using build-nodemcu service , used master branch. think has mqtt v3.1.1. i came across question , guess have ran same situation. though cause of issue has been given, how rid of problem has not been mentioned there. can please suggest how rid of problem? update [13-09-2016] here code using: sensorid = "sen_001" tgthost = "192.168.8.101" tgtport = "1883" mqttuserid = "admin" mqttpass = "word" mqtttimeout = 120 topicqueue = "/security" wifi_ssid = "lakmal 4g" wifi_password = "tf18bny3m" wifi_signal_mode = wifi.phymode_n esp8266_ip="" esp8266_netmask="" esp8266_gateway="" if wifi.

so have function: f(a,b,rho)=r . given a , b , r , find rho . came across inverse function in r, seems when function tries find rho , function cannot tell of a , b or rho specified rho , function cannot load given a , b . in addition, know rho between 0 , 1. a = -.7 b = 2 r <- function(rho,a,b){ # here defined long function of r # in terms of , b , rho } r_inverse=inverse(function(rho) r(rho,-.7,2),0,1) # r_value random value r_inverse(r_value) this not work. appreciate inverse function or other alternative way find rho given r , a , b .

in zsh there wait (for process or job) command, while (seconds == delay) command, , sched (do later if shell still running) command, no "delay" command. if there were, fear limited whole second delays. need "delay" statement can cause procedure/task nothing time specified in fixed point number or until clock time. most scripts use "sleep", have delay timer run without having open io; seeking ideal can accomplished within zsh. does know how perhaps make function (or maybe builtin/module) perform floating point idle delay in seconds? i'll argue making wrong assumption. zsh shell, , therefore purpose shell. 1 important point in being shell posix compatible shell. since zsh backward compatible bash , in turn backward compatible bourne shell should poisx shell. that means zsh must have access sleep since sleep required posix shell . and far go posix compatibility argument. practical use argument. systems use gnu coreutils
