You're just placing the value $value there. It doesn't have any sense to have $value without opening php tag there.

You need to echo the $value to have assign on rowid.

You should do

<input type="number" name="rowid" value="<?= $value ?>" readOnly><br>

or

<input type="number" name="rowid" value="<?php echo $value ?>" readOnly><br>

Additional Tip :

You can do the debug yourself by seeing the Page's source (view-source://yourpagename.php) or by Inspecting the area where you starring in from the Browser

echo $value inside value="" 

$value = 3;
<input type="number" name="rowid" value="<?php echo $value;?>" readOnly><br>

OR

<input type="number" name="rowid" value="<?= $value;?>" readOnly><br>
