我如何在for循环中使用唯一数组

Question

I want to use unique array in for loop. Please see my code.

Array ( [0] => Pritesh [1] => Pritesh [2] => Nilesh )

Now i have used "UNIQUE" function for fetch unique value

 Array ( [0] => Pritesh [2] => Nilesh ) 

But Now issue is when i use for loop for that like

for($p = 0; $p < count($unique); $p++)
    {   echo $uniques;
        echo  '<option value="'.$unique[$p].'">'.$unique[$p].'</option>';
    }   

So second value showing blank because array count is 2 and Key is 0,2 .

How i use this.

Answer 1

foreach($uniques as $key => $unique) {
  echo '<option value="'.$unique.'">'.$unique.'</option>';
}

As stated in the comment, you do not need to assign a variable for the key, if you don't need it. (I just used is as a handy reference). So you can simply do this:

foreach($uniques as $unique) {
  echo '<option value="'.$unique.'">'.$unique.'</option>';
}
