[RESOLVED] Invalid argument supplied for foreach() in code supplied in PHP5 Book

dmacman1962

Hi All,

I am trying some code from a PHP5 Unleashed book and either I made a mistake or they did.

I checked their site and there is no typos on their printed version and they do not have source code for that chapter, so I am looking for some help.

Here is the code...

$petshack['name'] = array('Rosco', 'Icky', 'Rex', 'Buster', 'Delta');
$petshack['owner'] = array('John', 'Ann', 'Cliff', 'Amy', 'Hollie');
$petshack['weight'] = array(20, 10, 3, 54, 30);
$petshack['animal'] = array('Dog', 'Cat', 'Iguana', 'Dog', 'Dog');

/* Begin sort */
asort($petshack['weight'], SORT_NUMERIC);

foreach($petshack['weight'] as $key=>$weight) {
echo "<tr>";
echo "<td>{$petshack['name'][$key]}</td><td>{$petshack['owner'][$key]}</td>";
echo "<td>{$weight}</td><td>{$petshack['animal'][$key]}</td>";
echo "</tr>";
}

I dont see the error, can someone help out here?

Thanks in advance,
don

I copied and pasted your code sample, and it ran with no errors on my PC. Maybe there's some syntax error earlier that is not manifesting until that line?

It works fine for me. Outputs with no errors.

What error message are you getting?

Is that the exact code? Did you copy and paste it from your file?

Have you tried refreshing the page or renaming the file, just to make sure it isn't a browser cache issue?

Doooh!

Thanks for all the suggestions, but it was none of the above.

I did not see that it saved it on my documents directory, not my WAMP directory.

Strange error though.

I saved it in my www directory on my laptop and it works, just like it did for everyone else. Sorry folks, it was late when I did this last nite, not enough Starbucks!

Owe you all one.

Happy Easter all,
Don
