I tried to make an **is\_Prime()** function in PHP. What do you think about this code?

```
<?php
function is_Prime($x)
{
  if($x <= 1)
  {
    echo $x. " is not a prime number.</br>";
    return false;
  }
  $data = array();
  for ($i=1;$i<=$x;$i++) 
  { 
    if(is_integer($x/$i))
    {
        array_push($data, ($x/$i));
    }
  }
  if(count($data)>2)
  {
    echo $x." is not a prime number</br>";
  }
  else
  {
    echo $x. " is a prime number</br>";
  }
}
?>

```

How to use?

```
for($i=0;$i<=100;$i++)
{
  is_Prime($i);
}

```
