How to screen output?

Question

I always have big problems with shielding, because my eyes just break when I try to check everything as an aspect:

while ($row_core = sqlsrv_fetch_array($result_core,SQLSRV_FETCH_NUMERIC)) { $gp++; echo '<input type="checkbox" name ="group-'<?php echo $gp; ?>" > <label for="<?php echo $gp; ?>"> $sql_s_core = "SELECT nameM FROM dbo.menu WHERE head_id=0"; $result_core = sqlsrv_query($conn,$sql); }

This is a piece of the menu, namely check box, the point is that the label values for it are pulled out of the database in a loop, the checkbox and label have id that should be new for each new box check, a new menu item. How do I properly shield it? In the loop I made a variable $gp which for each round of the loop becomes +1, then its value is displayed in the id of the element.

The approach itself is not very, to pull the base every time in a cycle, and if in a cycle there are 1000 values, 1000 queries?
@koks_rs output of the gp variable in name = "group- $ gp" id = "group- $ dp"
And why is there (inside echo ) a break in php tags then?
XZibit transmits a fiery sign: I put a gap pkhp in the echo, so that you could echo while you echo!
@SLy_huh, and try instead of trolling the next time to explain why this is not correct?

You have confused the concepts. Shielding:

 echo "Экранирование символов делается \"Так\"."; // Выдаст : Экранирование символов делается "Так".

You just need to insert the variable into the string:

 echo "<input type='checkbox' name='group-{$gp}'>"; // Выдаст : <input type='checkbox' name='group-1'>

So it will also work, the result is the same.

  echo "<input type='checkbox' name='group-$gp'>";

Braces are needed to display more complex expressions, such as accessing an element of an array:

 $arr = array("value" => "foo"); echo "это {$arr['value']} !"; // Выдаст: это foo !

 echo '<input type="checkbox" name ="group-' . $gp . '">'; echo '<label for="' . $gp . '">';
