‘%s’ operator with non-integer operand
Description
The break and continue operators only accept a positive non-null literal integer.
Beyond the obvious improper code that is break 1.2, even storing the number of break levels in a constant or a variable is not a valid syntax. It can only accept an integer.
Example
<?php
break 1.2;
const A = 1;
break A;
?>
Literal Examples
- ‘break’ operator with non-integer operand
- ‘continue’ operator with non-integer operand
Alternatives
- Round the number to the closest integer.
- Remove the call to break altogether.
- Move the loop in a separate method, and use return to break out of the loop.
- Use a goto to jump out of the loop.
