Trying to change statement so create_radio function is only called once (PHP) -

-

i have function creates radio button in php:

// function creates radio button. // function takes 2 arguments: value , name. // function makes button "sticky". function create_radio($value, $name = 'gallon_price')  {     // start element:     echo '<input type="radio" name="' .          $name .'" value="' . $value . '"';      // check stickiness:     if (isset($_post[$name]) && ($_post[$name] == $value))      {         echo ' checked="checked"';     }       // complete element:     echo " /> $value "; } // end of create_radio() function.

i leave php form create html form , call function 3 times values represent 3 different gas prices.

<span class="input">         <?php             create_radio('3.00');             create_radio('3.50');             create_radio('4.00');         ?>     </span>

i wondering how change code possible same output , make 1 call create_radio function.

thanks!

function create_radio($value, $name = 'gallon_price')  {     $output = "";     if (is_array($value)) {         while (count($value) > 0) {             $arr_value = array_pop($value);             $output .= create_radio($arr_value);         }     } else {         // start element:         $output .= '<input type="radio" name="' .          $name .'" value="' . $value . '"';          // check stickiness:         if (isset($_post[$name]) && ($_post[$name] == $value))          {            $output .= ' checked="checked"';         }        // complete element:         $output .= " /> $value ";     }     return $output; }

a quick bit of recursion allow function work arrays , non arrays. note: in html need echo call create_radio not call it.

-
i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
