我如何使for语句具有其他

Question

I have a databse that has food reviews on it, and I want to show if a food is vegetarian or not. I want to add a echo "No"; but I don't know how.

I've tried using else, but it doesn't show. I've also tried <?php for($x=1;

Here is my code:

<p>Vegetarian: <span class="sub_heading"><?php for($x=0; $x < $find_rs['Vegetarian']; $x++)
                    {
                        echo "Yes";
                    }
                        ; ?></span></p>

I want it to show no if it is 0 and yes if it is 1

Answer 1

<p>
    Vegetarian: 
    <span class="sub_heading"><?= $find_rs['Vegetarian'] ? "Yes" : "No"?></span>
</p>

Answer 2

Simply add an if conditional inside of your loop that checks against the value of $x :

for ($x=0; $x < $find_rs['Vegetarian']; $x++) {
    if ($x == 1) {
        echo "Yes";
    }
    else if ($x == 0) {
        echo "No";
    }
    else {
        echo "x wasn't either 0 or 1 -- x was $x";
    }
}

Note that the final else condition will output the value of $x due to the use of double-quotes.

Answer 3

if the condition only 2, just using if else statement,

<?php
for($x=0; $x < $find_rs['Vegetarian']; $x++){
     if($x == 1){echo 'Yes';}else{echo 'No';}
}
?>
