How to use an associative array value for calculation in PHP? -


i performing calculation using user input , associative arrays. below php code

$class          = $_post['class']; $size           = $_post['size']; $gasket         = $_post['gasket']; $connection     = $_post['connection'];  $flange150 = array(      array( flangesize  => 0.5,      /* inches */         flangeclass => 150,         flangethick => 0.38,     /* inches */         boltdia     => 0.5,      /* inches */         totalbolt   => 4     ),     array( flangesize  => 0.75,     /* inches */             flangeclass => 150,             flangethick => 0.44,     /* inches */             boltdia     => 0.5,      /* inches */             totalbolt   => 4     ),  );

the user input size stored in variable $size , using variable need select array has same value user input (flangesize in array). array must take value of flangethick calculation. dont know how perform this. please me in regard.

use foreach this

$flangethick = ""; foreach ($flange150 $key =>$val) {       if ($val['flangesize'] == $_post['size']) {            $flangethick = $val['flangethick'];       } } echo $flangethick;

so, have value

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
