 <script>

function display_check(i)

{

    if(i==0) {return true;}

    else if(i!=0) {return false;}

}
 
function run()

{

    if (t-1 >= 0)

    {

        t = t - 1; 

        document.getElementsByValue('text').innerHTML =display_check(t);

    }

}

</script>

<body>

<input type="button" onclick="run()" />

<?

$text = "<p id=\"text\"></p>"

echo $text;

?>

</body>

This case can display the "false" and "true" on the screen. But cnt display in if else statement.
who know other way can use in if else statement to display? Thank you.

Doesn't make sense. You have your php calling one function which calls another? What "if else" statement are you talking about?

Unfortunately, there are lots of mistakes and bad algorithms in your program.
First of all you should know that JavaScript and PHP are not executed together.
PHP runs on the server and sends HTML and JavaScript to the browser. On the browser, runs the JavaScript.
And there is nothing called getElementByValue in JavaScript.
If a condition provided in an if statement is not true, it automatically executes the else statement. You don't have to provide the opposite condition in another if statement.

This makes it easier for our Experts to read and understand it. Failing to do so creates extra work for the moderators, thus wasting resources, otherwise available to answer the members' questions.
