I want to show a defined variable by using for loop like this code:

<?php
  define("V_1","Variable1");
  define("V_2","Variable2");
  define("V_3","Variable3");
  for ($f=1;$f<4;$f++){
    echo "<p>".V_.$f."</p>";
  }
?>

Is there any one can help me with this?

`define` creates constants, not variables. Use an array, not separate constants. – Barmar Jan 11 '18 at 21:49
To echo your `constants`: http://php.net/manual/en/function.constant.php – IncredibleHat Jan 11 '18 at 21:49
Is not there any way to echo this? – Mousa Saleh Jan 11 '18 at 21:50
`echo constant('V_'.$f);` But learn how to quote string literals like `'V_'`, and the difference between constants and variables.... both are fundamentals of any kind of programming. – Mark Baker Jan 11 '18 at 21:50
That was the answer, thank you @MarkBaker – Mousa Saleh Jan 11 '18 at 21:53
