单击时替换按钮颜色

I have generated a list of buttons , and would like each one to independently change colour when click, so they go red/green alternately on each click.

<?php
$getInfo = getAllRows();

$button = '<button type="button" id ="toggle" ></button>';?>


</php>
<html>
<div class ="enableButtons">
//there are 5 values to iterate over
<?php foreach ($getInfo):
echo $button;
?>
<?php endforeach ?>

                 </div>
 </html>

<script>
$('#toggle').click(function(){
  $(this).toggleClass('green');

});

</script>

.green
{
    background-color:green;
}

The problem Im having is that only the first button seems to be toggling colour , the others dont do anything when I click! Also Im unsure how to make it toggle from red/green alternately.

Any help would be great cheers!

    The problem is with the id. It seems all the button will have same id which is wrong markup.

    Try by replacing id with a common class

    $button = '<button type="button" class="someCommonCLass" ></button>'
    

    In js

    $('.someCommonCLass').click(function(){
      $(this).toggleClass('green');
    
    });
