如何将时间（秒）与名称相关联

Question

I am trying to get the time (seconds) from the server and then associate this to a student name:

    $info = getdate();
    $sec = $info['seconds'];
    $current_sec = $sec;
    echo $current_sec;
    echo " | ";
    if ($current_sec == '1') {echo 'John';}
    else if ($current_sec == '2') {echo 'Mary';}
    else if ($current_sec == '3') {echo 'Bill';}
    ~~~
    else if ($current_sec == '60') {echo 'Bob';}
    echo " | ";
    echo $current_sec;

However I seem to get the same result each time no matter when I refresh the page:

15 | John | 1

where 15 is the actual seconds.

I would be grateful for any help.

Answer 1

You're if statements have a typo:

 if ($current_sec = '1')

Is always true. Try:

 if ($current_sec == '1')

Answer 2

因为比较运算符是== ，而不是=
