loops - Php change background color on different value -


so have code creates select in form, wondering how can make add different background color when $value different.

please have in mind $value not same text , may change.

php code:

<div class="line"><select style="width: 100%;" name="fields['.base64_encode('itinerary - days').']" class="required">   <option value="">--- select deck & itinerary ---</option>';  foreach($main_title_array $key => $value):     $f.= '<option style="background-color:" value="'.$value.'">'.$value.' / '.$type_array[$key].'</option>'; endforeach;  $f.='</select></div>';

result:

 <select class="required" name="fields[sxrpbmvyyxj5ic0grgf5cw==]" style="width: 100%;">       <option value="">--- select deck &amp; itinerary ---</option>       <option value="lower deck" style="background-color:">lower deck / discovery itin 4d &ndash; 3n</option>       <option value="lower deck" style="background-color:">lower deck / discovery itin 5d &ndash; 4n</option>       <option value="lower deck" style="background-color:">lower deck / discovery itin 8d &ndash; 7n</option>       <option value="main deck" style="background-color:">main deck / discovery itin 4d &ndash; 3n</option>       <option value="main deck" style="background-color:">main deck / discovery itin 5d &ndash; 4n</option>       <option value="main deck" style="background-color:">main deck / discovery itin 8d &ndash; 7n</option>       <option value="upper deck" style="background-color:">upper deck / discovery itin 4d &ndash; 3n</option>       <option value="upper deck" style="background-color:">upper deck / discovery itin 5d &ndash; 4n</option>       <option value="upper deck" style="background-color:">upper deck / discovery itin 8d &ndash; 7n</option>     </select>

wanted result:

<select class="required" name="fields[sxrpbmvyyxj5ic0grgf5cw==]" style="width: 100%;">   <option value="">--- select deck &amp; itinerary ---</option>   <option value="lower deck" style="background-color:red">lower deck / discovery itin 4d &ndash; 3n</option>   <option value="lower deck" style="background-color:red"">lower deck / discovery itin 5d &ndash; 4n</option>   <option value="lower deck" style="background-color:red"">lower deck / discovery itin 8d &ndash; 7n</option>   <option value="main deck" style="background-color:white">main deck / discovery itin 4d &ndash; 3n</option>   <option value="main deck" style="background-color:white">main deck / discovery itin 5d &ndash; 4n</option>   <option value="main deck" style="background-color:white">main deck / discovery itin 8d &ndash; 7n</option>   <option value="upper deck" style="background-color:black">upper deck / discovery itin 4d &ndash; 3n</option>   <option value="upper deck" style="background-color:black">upper deck / discovery itin 5d &ndash; 4n</option>   <option value="upper deck" style="background-color:black">upper deck / discovery itin 8d &ndash; 7n</option> </select>

try solution

// list of colors $colors = array('red', 'white', 'black','blue');  //the lenght of colors available $lenght_colors = count($colors);  //store last deck $last_deck = null;  //counters $count = 0;  // avoid warnings $f = null;  foreach($main_title_array $key => $value) {     // switch colors     if($last_deck != $value)     {         // check if reached limit of colors available if yes reset count         if($count != $lenght_colors)         {             $count++;         }         else         {             $count = 0;         }     }      $f .= '<option style="background-color:'.$colors[$count].'" value="'.$value.'">'.$value.' / '.$type_array[$key].'</option>';     $last_deck = $value; }
