Bu php kodu yanlış olan ne

0 Cevap php

Nedense bu kodu php echo değil. Nedenini anlamaya görünüyor olamaz.

<?php
function prob1(){
    $sum1 = 0;
    for($i=1; $i<11; $i++){
        $sum1 = $sum1 + $i; 
    }
    echo "Sum of numbers 1 - 10 is:". $sum1;
}
prob1();
?>

Herhangi bir fikir?

UPDATE: Here is the entire web page that it exists in.

<h1>Problem 1:</h1>

<?php
function prob1(){
    $sum1 = 0;
    for($i=1; $i<11; $i++){
        $sum1 = $sum1 + $i; 
    }
    echo "Sum of numbers 1 - 10 is:". $sum1;
}
prob1();
?>

<p>
A. This is a server-side program. The code is executed on a web server and the results are returned to the user as HTML.
<br />
B. You can use javascript to accomplish the same calculation. Javascript code is executed client-side; meaning the user's machine will execute the code and return the result.
<br />
C. There is no need to use PHP in a scenario like this. Calculations such as these are more efficiently executed client-side.

<h1>Problem 2</h1>

<?php

function prob2($x){
$y = 0;

if ($x<5)
{
    $y = pow($x, 3) + 5*($x, 2) + 3;
}
else
{
    $y = pow($x, 3) - 9*pow($x, 2) + 12;
}   

echo "For X=" . $x . " Y=" + $y;
}

prob2(3);
prob2(8);

?>

<p>A. Yes, you can write the same code using javascript. In this situation, it wouldn't be necessary to use php unless you wanted to hide the calculation from the user.</p>
