Im going through a PHP tutorial and about halfway through it starts using \n all over the place without any explanation - What does this do?

Google didnt help as it justs searches for the n lol

Thanks!

"\n" is a unix escape code meaning "new line"

see also: \t for tab, \\ for backslash, and so on

Ok - i think i under stand that - however i have come up with another problem:

I have been given code to make a table - as far as i can tell its the same as i am copying from but it will not work

Code:

<html>
<head>
<title>Table Example</title>
</head>
<body>
<table border=1 bgcolor=yellow>

<?php

$AcmeCars = array ("Ford", "Dodge", "Chevy");
$AcmeCarId = array ("K234", "J987", "F982");

for ($×=0; $× < count ($AcmeCars); $×++) {
print "<tr><td>$AcmeCarId[$×]</td>";
print"<td>$Acme Cars[$×]</td></tr>\n";
}

?>

</table>
</body>
</html>

Can anyone see the problem?

Thanks

Works fine for me though, $Acme Cars needs to be $AcmeCars on the last print line.

Doesn't 'count' need to be changed to '$count', then initialised?

As far as I can tell, you're saying "keep looping round this code until $X is not less than count". Assuming I've understood it correctly, count must be a number. Therefore, above the loops, put:

$count = 5;

then in the loop, change 'count' to '$count'.

That should then go through the loop 5 times.

What error is PHP throwing at you anyway?

um... no, count is a php method to count the number of elemts in an array. see http://uk2.php.net/count
