shell - PHP System Call Always Fails -


(seemingly) no matter command try run php's system function, command nothing , fails exit code 1. example,

system("echo 'this should work'", $retval);

sets $retval = 1. does

system("dir", $retval);

as running executable i've written; when run

vfmt -h cat.v

from cmd.exe command works , returns exit code 0, running

system("vfmt -h cat.v", $retval);

again sets $retval = 1. vfmt.exe file in same directory src.php script attempting these system calls.

i @ wit's end trying figure out what's wrong. possibly causing issue?

you should check php.ini line next:

disable_functions =exec,passthru,shell_exec,system,proc_open,popen,curl_exec,curl_multi_exec,parse_ini_file,show_source                    ^^^^          ^^^^^^^^^^^^^^^^^^

and such.

also check "safe mode" status, (php ver. < 5.4) if have enabled can execute files within safe_mode_exec_dir , on...

more information in doc , execution of commands here , system here.

javascript - Highcharts multi-color line -

Image
i looking create highchart multi-colored line. if goes down under value, become red, , when comes on value, become green . here picture example: or maybe highcharts have other charts models differentiate high or low level color? you can achieve coloring using lineargradient coloring: color: { lineargradient: { x1: 0, x2: 0, y1: 0, y2: 1 }, stops: [ [0, 'red'], [0.25, 'yellow'], [0.50, 'green'], [0.75, 'yellow'], [1, 'red'] ] } here 0 in stops relates minimum value of series , 1 maximum value, , in between percentages between values. if find percentages according values prior creating chart use correct stops values make relate specific values in data (at least approximately). see this jsfiddle example .
