1.2.1191. Ternary In Concat¶

Ternary and coalesce operator have higher priority than dot ‘.’ for concatenation. This means that : prints actually 'E', instead of the awaited 'B0CE'.

To be safe, always add parenthesis when using ternary operator with concatenation.

<?php
  // print B0CE as expected
  print 'B'.$b.'C'. ($b > 1 ? 'D') : 'E';

  // print E, instead of B0CE
  print 'B'.$b.'C'. $b > 1 ? 'D' : 'E';

  print 'B'.$b.'C'. $b > 1 ? 'D' : 'E';
?>
