PHP if statement

Hello,

I would like to be able to make a PHP file that reads in a value from itself (ie define a var inside the header of the PHP file) and then display HTML content based on that

for example (psuedo code):
a new var (boolean) = true

if the new var is true
then display:
<html>
Some text ...
</html>

else
<html>
The site is down...
</html>

rumblefiz

what about:

<?
$isDown = 1;
if($isDown) {
$s = Down";
} else {
$s = "Not down";
}

echo $s;
?>

rumblefiz

a clearer ex:

<?
$bIsDown = false;
if($bIsDown) {
echo "<html>";
echo "<head><title>Site Is Down</title></head>";
echo "<body>Come back later...</body>";
echo "</html>";
} else {
echo "<html>";
echo "<head><title>Welcome</title></head>";
echo "<body>The site is up...</body>";
echo "</html>";
}
?>

hope that helps

it may also be easier (depending on how much text) to do the following:

<?
$bIsDown = false;
if($bIsDown) {
$s = "The site is down";
} else {
$s = "The site is up";
}
?>

<html>
<head><title>My Page</title></head>
<body>
<?= $s; ?>
</body>
</html>

rumblefiz:

is there a way to have $s be a multi line
string, i.e. a chunk of code? without having to type everything on one long line?

i am not really sure what you are asking. take a look at the following samples and see if any answer your question:

<?
$bIsDown = false;
if($bIsDown) {
echo "
<html>
<head><title>Site is down</title></head>
<body>
The site is down. Please come back another time.
You can span multiple lines, of course!!!
</body>
</html>
";
} else {
echo "
<html>
<head><title>Site is up</title></head>
<body>
The site is up. Welcome!!!!
</body>
</html>
";
}
?>

you could also do like:

<?
$bIsDown = false;
if($bIsDown) {
?>
<html>
<head><title>The site is down</title></head>
<body>
The site is currently down. Please come back!!!!
</body>
</html>
<? } else { ?>
<html>
<head><title>The site is up</title></head>
<body>
The site is up. Welcome!!!!
</body>
</html>
<? } ?>

or like this:

<?
$bIsDown = false;
if($bIsDown) {
$s = "The site is currently down. Please come back" .
"This is another line." .
"And another....";
} else {
$s = "The site is up!" .
"Welcome. This is another line";
}
?>

<html>
<head><title>Site Status</title></head>
<body>
<?= $s; ?>
</body>
</html>

i hope these help. if not, give me an ex of what you are trying to do and i will be glad to assist further.

knight00,

out of curiosity, what is the difference between your post and my post above (besides the braces) that is:

<?
$bIsDown = false;
if($bIsDown) {
?>
<html>
<head><title>The site is down</title></head>
<body>
The site is currently down. Please come back!!!!
</body>
</html>

<? } else { ?>

<html>
<head><title>The site is up</title></head>
<body>
The site is up. Welcome!!!!
</body>
</html>

<? } ?>

They both work, and they both have to same outcome.

However, the style I used was designed for spanning your control structures if/while/for/etc across multiple code blocks.
