请检查以下代码,您所做的错误在代码中发表了评论: -
<?php
error_reporting(E_ALL); // check all error including warning and notice error too
ini_set('display_errors',1); // display errors
function add($x,$y) {
$result= $x+$y;
return $result;
} // ; not needed
$number1= $_POST['n_1'];
$number2= $_POST['n_2'];
echo $number1." + ".$number2." = ".add($number1,$number2);// using “ is wrong
for ($i=5;$i<=50;$i+=5) {
echo $i."</br>";
} // ; not needed
$j=10;
while ($j>0){
echo $j."</br>"; // using “ is wrong
$j--;
}//; not needed
?> <!-- closing error-->
