[Tutorial] PHP ~ Love Calculator

[lolwut]

These things are always popular with everyone, so I decided to code one to try to make my hunger pains go away... This uses a the rand(); function and echo's an appropriate message to their number.
It's entriely self contained.

<?php
//LOVE CALCULATOR!!!
echo("
<font size=\"2\" face=\"Verdana\">
<form method=\"POST\">
Your Name: <input type=\"text\" name=\"name1\">
<br />
Crushes Name: <input type=\"text\" name=\"name2\">
<br />
<input type=\"submit\" value=\"Calculate\">
</form>
");
//Woo. So now we choose what to do if the forms sent.
$name1 = $_POST['name1']; // The "Your Name:" variable.
$name2 = $_POST['name2']; // The "Crushes Name:" variable.
if(!$name1){ exit(); }
$rand = rand(1,99); // Uses the rand(); function in PHP to make a number between 1 and 99
echo("<b>$name1</b> and <b>$name2</b>'s love rating is <b>$rand</b>.<br />"); // Result. We've echoed it. Now we'll do a "Cupids Comment" thing.
if($rand <= "20"){
echo("Cupids Comment: Face it, it's not gonna work out between the two of you!");
}
if($rand <= "40" && $rand >= "21"){
echo("Cupids Comment: There could be love between you two, but then again, maybe not.");
}
if($rand <= "60" && $rand >= "41"){
echo("Cupids Comment: Try it and see, there's about a 50/50 chance.");
}
if($rand <= "80" && $rand >= "61"){
echo("It's likely, the chances of the spark going are preety slim.");
 }
if($rand <= "99" && $rand >= "81"){
echo("Cupids Comment: There's almost definiatley love there! Go ahead. Your not gonna be heartbroken.");
}
echo("</font>");
?>

Fixed all errors, see it in action at http://tazroger.net/edd/lovecalc.php.

Wouldn't let me edit;
Better code, fixed >= errors;

<?php
echo("<font face=\"Verdana\" size=\"2\">");
//LOVE CALCULATOR!!!
if(!$_POST['calc']){
echo("
<form method=\"POST\">
Your Name: <input type=\"text\" name=\"name1\">
<br />
Crushes Name: <input type=\"text\" name=\"name2\">
<br />
<input type=\"submit\" value=\"Calculate\" name=\"calc\">
</form>
");
}else{
//Woo. So now we choose what to do if the forms sent.
$name1 = $_POST['name1']; // The "Your Name:" variable.
$name2 = $_POST['name2']; // The "Crushes Name:" variable.
if(!$name1){ echo("Please enter your name!"); exit(); } // If they didn't post their name, reject the form.
if(!$name2){ echo("Please enter your crushes name!"); exit(); } // If they didn't post their crushes name, reject the form.
$rand = rand(1,99); // Uses the rand(); function in PHP to make a number between 1 and 99
echo("<b>$name1</b> and <b>$name2</b>'s love rating is <b>$rand</b>.<br />"); // Result. We've echoed it. Now we'll do a "Cupids Comment" thing.
if($rand <= "20"){
echo("Cupids Comment: Face it, it's not gonna work out between the two of you!"); // Message if love rating is under 20.
}
if($rand <= "40" && $rand >= "21"){
echo("Cupids Comment: There could be love between you two, but then again, maybe not."); // Message if love rating is under 40.
}
if($rand <= "60" && $rand >= "41"){
echo("Cupids Comment: Try it and see, there's about a 50/50 chance."); // Message if love rating is under 60.
}
if($rand <= "80" && $rand >= "61"){
echo("It's likely, the chances of the spark going are pretty slim."); // Message if love rating is under 80.
 }
if($rand <= "99" && $rand >= "81"){
echo("Cupids Comment: There's almost definiatley love there! Go ahead. Your not gonna be heartbroken.");
}
$referer = $_SERVER['HTTP_REFERER'];
echo("<br /><a href=\"$referer\">Try Again?</a>"); // Shows Try Again message.
}
echo("</font>");
?>

Well its different and definetly a good try. I may use it on my site if i have random 'generators' as such. would rep you if I could.

Learn to indent your code.

Quoted for truth.

[lolwut]

Thanks all, indentings hard as hell in a web editor, unless you wanna use spaces. I prefer tabs.

[timROGERS]

I was gonna make one of these too, I'll indent it for you (maybe)

<?php
if ($_GET['action'] == "submit")
{

    $name1 = $_POST['name1'];
    $name2 = $_POST['name2'];

    if ($name1 == null)
    {
        echo "Please enter your name!";
        exit;
    }
    if ($name2 == null)
    {
        echo "Please enter your crushes name!";
        exit;
    }

    $rand = rand(1, 99);
    echo "<strong>$name1</strong> and <strong>$name2</strong>'s love rating is <strong>$rand</strong>.<br />";

    if ($rand <= "20")
    {
        echo ("Cupids Comment: Face it, it's not gonna work out between the two of you!"); // Message if love rating is under 20.
    }
    if ($rand <= "40" && $rand >= "21")
    {
        echo ("Cupids Comment: There could be love between you two, but then again, maybe not."); // Message if love rating is under 40.
    }
    if ($rand <= "60" && $rand >= "41")
    {
        echo ("Cupids Comment: Try it and see, there's about a 50/50 chance."); // Message if love rating is under 60.
    }
    if ($rand <= "80" && $rand >= "61")
    {
        echo ("It's likely, the chances of the spark going are pretty slim."); // Message if love rating is under 80.
    }
    if ($rand <= "99" && $rand >= "81")
    {

    }
    $referer = $_SERVER['HTTP_REFERER'];
    echo "<br /><a href=\"$referer\">Try Again?</a>"; // Shows Try Again message.
    exit;
}
?> 
<font face="Verdana" size="2">
<form method="post" action="?action=submit">
Your Name: <input type="text" name="name1">
<br />
Crushes Name: <input type="text" name="name2">

</font>

Sounds stupid but what does indent mean:S

Sounds stupid but what does indent mean:S

From this:

<?php
$name = "bob";
if($name == "bob") {
echo "hey";
}else{
echo "bye";    
}
?>

to

<?php
$name = "bob";
if ($name == "bob")
{
    echo "hey";
}
else
{
    echo "bye";
}
?>
