Please help me with this very basic variables question...

Expand Post »

Hi folks,
I am brand new to PHP, but I am trying to learn from an online tutorial. I'm using this one:
http://inpics.net/tutorials/php/variables24.html

I'm sure there are many others, but that's where I'm at now. I am on the variables section, and they present this code:

PHP Syntax (Toggle Plain Text)
<?php
 
# This script demonstrates how to
# create a numeric array.
 
@AcmeInventory = (178,286,387);
 
print "$AcmeInventory[0]<br>\n";
print "$AcmeInventory[1]<br>\n";
print "$AcmeInventory[2]<br>\n";
 
print "<p>We just created a list of numbers using an array variable!";
 
?>
<?php

# This script demonstrates how to
# create a numeric array.

@AcmeInventory = (178,286,387);

print "$AcmeInventory[0]<br>\n";
print "$AcmeInventory[1]<br>\n";
print "$AcmeInventory[2]<br>\n";

print "<p>We just created a list of numbers using an array variable!";

?>

The problem is when I run this, I get this error:

Parse error: syntax error, unexpected '=' in /home/content/m/b/i/mbirame/html/PHPscripts/numberlist.php on line 7

I have PHP5 running on my server...have things changed in 5 to make me need different code for the variables?

Thank you!
Joel

Re: Please help me with this very basic variables question...

It seems there is an error in the tutorial you are using. the "@" symbol is actually used to suppress an error that the following function might throw: http://www.tuxradar.com/practicalphp/19/8/12

I'm assuming the author ment that to be a "$" symbol, as that indicates a variable. that line should be $AcmeInventory = (178,286,387); .

EDIT: If that doesn't work, change that line to this:
$AcmeInventory = array(178,286,387); .

Yes-I had to include the "array" as well...strange, could this have been for an old version of PHP or just a bad tut?

I'm assuming it's just a bad tut because of the lack of attention to detail and testing. The @ symbol was never for variables.
