Here is a good example:
1 | echo (2 == 3) ? 'x' :'y'; |
this will echo “y”.
You need to put echo in front, you can’t put echo inside the ternary statement.
Another example:
2 3 4 5 6 7 | <?php $var1 = 'America'; $var2 = 'Is great'; echo ($var1 === $var2)? 'It is not': 'It is'; ?> |
You can put the ternary if else to be a variable, like in this simple example:
3 4 5 6 7 8 9 10 | <?php $var1 = 'America'; $var2 = 'Is great'; $answer = ($var1 === $var2)? 'It is not': 'It is'; echo $answer; ?> |
echo will return “It is”.
And an example with a function:
4 5 6 7 8 9 10 11 12 | <?php function test($color){ return ($color == 'blue') ? 'It is blue' : 'It is not blue'; } echo test("red"); ?> |
Looks like the else statement can’t be unset, meaning that you can skip putting the : sign. You can just put :”; So it will have an empty value there.
Another example with an input:
5 6 7 8 9 | <?php $var = (2 == 2) ? 'true' : 'false'; echo '<input name="input" type="text" value="'.$var.'">'; ?> |
