if条件有什么错误？

Question

echo $approver;输出＆＃34;主管＆＃34;在网页上，但代码echo "Supervisor is working <br />"不会输出任何内容。

$approver = $_POST['approver'];

echo $approver; 
echo "<br />";

//echo "It is working <br />";
if ($approver == "Supervisor")
    echo "Supervisor is working <br />";

Answer 1

$_POST["approver"]字符串中有一些空格很可能。为避免这种情况，请尝试更改：

$approver = $_POST['approver'];

为：

$approver = trim($_POST['approver']);
