php密码，比较，返回true或false

Question

I have a file on my server called "pform.php", this is what it looks like:

<form action="password.php" method="get">
<input type="text" name="password13"/>
<input type="submit" value="Submit!"/>
</form>

I have it transfer to another file called "password.php", this is what it looks like:

<?php

$text=$_GET["password13"];
$right="You entered the right password!";
$wrong="You entered the wrong password!";

if($password13)=="test"
{
    echo $right;
}
else
{
    echo $wrong;
}
?>

What can I change on line 7 that makes it compare the password "test" and return true or false?

Thanks!

Answer 1

if($password13)=="test"

应该

if($text=="test")

Answer 2

That's very simple:

$trueOrFalse = ($password13=="test");
if ($trueOrFalse) {
   ...

Or put it into the if clause directly:

if ("test" === $password13)
{
    ...

Answer 3

if ($text == "test")

不

if ($text) == "test"
