<b> This in bold</b> <u>This is underline</u> <i>This is italic</i>
Put the above tags in your code
Why have you used
$mod5 = $i %5
t should be
$mod10 = $i%10

What of this way?

$str = ‘

$i

’;
$str .= “red”;
echo $str; // gives: the color is red
11

What of this way

$str = '

$i

';

$str .= "red">$i

';

echo $str; // gives: the color is red

```
13

…

$str = '<p style="color";

$str .= "red";

echo $str; // gives: the color is red

...
15 
$str = '<p style="the color is"><u>$i</u></p>';
$str .= "red";

echo $str; // gives: the color is red
17

Okay, but how do you concatenate a string in PHP?

If it so urgent you are in the wrong place, this is not an instant chat, people have lifes and come here to help when they can.

I don’t know much of php, but it seems to me you are italicing both each 3rd and 10th number. you are not using the bold tag anywhere (<b> or <strong> depending on how new is the html you need to use)

Instead you are underlining everything. Ignore the thing about prime numbers if you don’t know what they are, be sure to implement the first two points first, then you can try to implement the bonus part

27

Thanks. I have corrected it as you stated above. Check the code below:

<b>This is bold</b> 
<u>This is underline</u> 
<i>This is italic</i>
<?php  
     for ($i = 1; $i <= 1000000; ++$i) {

     $mod3 = $i % 3;
     $mod10 = $i % 10;
     $str = '';
     if (!$mod3) {
       $str .= '<p style="color=red"><i>$i</i></p>';
     }
     if (!$mod10) {
       $str .= '<p style="color=blue"><b>$i</b></p>';
     }
     if ($mod3 && $mod10) {
       $str .= '<p style="color=purple"><u>$i</u></p>';
     }
     echo $str, "\n"; // gives: the color is red, blue, purple
    }
?>
28

You use colons in CSS.

You’re still not concatenating anything.
Did you notice that dot over there?

You need to use that to concatenate strings.

29

yeah, no… ignore the part about prime numbers, that’s not how you calculate prime numbers. Ignore that part.

For now just make sure that every 30th number is both bold and italic, not underlined (because it is not a prime number)

once that works you can think about prime numbers, not before, as that needs a different kind of calculations

30

Pls show me how to. Give sample

31

Try to use a dot to concatenate strings. Syntax is $something . "someotherstring".
