How to send variable with link in PHP

Question

so I’m having doubts on how to make this link in php:

<a href="DepoimentosPT-BR.php?id=<?php echo $_SESSION['idusuario']; ?>">Depoimentos</a></li>

as you can see this link is in html and then is called php to send the $ with and the ? id.

I want to know how I do this way in php same type:

echo "...";

Answer 1

Considering $id = $_SESSION['idusuario'].

1. Concatenating strings:

   echo '<a href="DepoimentosPT-BR.php?id='.$id.'">Depoimentos</a>';
   

2. Interpolating strings:

   echo "<a href='DepoimentosPT-BR.php?id={$id}'>Depoimentos</a>";
   

3. Formatting strings with sprintf:

   echo sprintf("<a href='DepoimentosPT-BR.php?id=%d'>Depoimentos</a>", $id);
   

4. Translation of characters from string:

   echo strtr("<a href='DepoimentosPT-BR.php?id={id}'>Depoimentos</a>", '{id}', $id);
