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.
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;
The syntax for the ternary operator is like that:
ternary_expression ::= boolean_expression ? expression : expression
The problem with your example is that break is not an expression but a statement. Your syntax could work if you had an expression instead, although it would seem awkward. I would suggest a normal if in any case.
? :is "just like if-else"
