Mind you can also do that with more $s:

<?php

  $var1 = 'var2';
  $var2 = 'nameOfVariable';

  $nameOfVariable = 'The value I want!';

  echo $$$var1;

?>

And you can use curly brackets:

<?php

  $var1 = 'nameOf';
  $var2 = 'TheVariable';

  $nameOfTheVariable = 'Another value I want!';

  echo ${$var1 . $var2}; // Use concatenation to generate the variable name and then access it //

?>

I would like to ask a question, How to show variable in between the text.
E.g., I have
“var1 = $_POST['username'];”
I want to show it something like this,
“Hello [username]“.
How to do it?
I tried this but it didn’t work,
“echo Hello $var1;”
Please help me regarding this.

If you need to create variables from an array there are two options.

The first uses php extract()

 'Baylor', 'email' => 'baylor@example.com'));
echo $name; // Baylor
echo $email; // baylor@example.com

// example: http://baylorrae.codepad.org/VdIA118O

The second options which will give you more control is php list()

<?php

list($name, $email) = array('Baylor', 'baylorrae@gmail.com');

echo $name;
echo $email;

// example: http://baylorrae.codepad.org/WejSCaCB
