prime no or not

First of all, I want to tell you that what is the prime no.

Prime no is the no which can’t be divided by other than 1 and itself.

Prime No? Yes : No;

<?php
$no=8;
$prime=true;
for($i=2;$i<($no/2);$i++)
{
    if($no%$i==0){
        $prime=false;
        break;
    }
}
if($prime==true){
    echo "<br/>Number is Prime<br/>";
}
else{
    echo "<br/>Number is not prime<br/>";
}
?>

String is palindrome or not

<?php
$origing_str = "khan";
$opesite_str="";
$leng = strlen($origing_str);
$str_array=str_split($origing_str);
for($i=$leng-1;$i>=0;$i--)
{
    $opesite_str.= $str_array[$i];
}
if($origing_str==$opesite_str){
	echo 'string is palindrome';
}else{
	echo 'string is not palindrome';
}

$origing_str.="";
$opesite_str="";
$leng = strlen($origing_str);
$str_array=str_split($origing_str);
for($i=$leng-1;$i>=0;$i--)
{
	$opesite_str.= $str_array[$i];
}
echo "Opposite Number: ".(int)$opesite_str;
 
?>
