Question

I have these code:

<?php 
$i=0;
while (true):
   echo "test";
   $i<4 ? $i++ : break;
endwhile; 
?>

error message:
Parse error: syntax error, unexpected T_BREAK in C:\xampp\htdocs\data\index.php on line 5

there is a syntax error with the if condition, I can really make out what. can anybody help. thanks a lot.

Answer 1

The ternary operator is used for assignment or to return a value. You cannot place break in the else (:) case of a ternary operation.

// Assignment
$x = $i<4 ? $i : 0;
// For a value returned into a function argument $i or 0
do_something($i<4 ? $i : 0);

It cannot be used for a regular else case containing a language construct as you’re doing with break. Instead use a regular if()

$i = 0;
while (true):
  if ($i<4) {
    $i++
  }
  else {
    break;
  }
endwhile;
