Courses Plus Student 94,610 PointsHi Robert,
In this earlier video at around 0:48, https://teamtreehouse.com/library/build-a-basic-php-website/listing-and-sorting-inventory-items/associative-arrays
the $catalog array was cut from catalog.php and moved to data.php where it was changed from a simple array of strings to a multi-dimensional array.
Did you leave the old catalog array in catalog.php? If your code is still using that array then it would produce the type of warning you're getting.
That warning happens whenever you try to access a character of a string using a string index instead of an integer index.
I've included a code sample below that illustrates how this warning happens.
<?php
$name = "Mike";
echo $name[0]; // outputs M
echo $name["first"]; // issues WARNING Illegal string offset 'first' on line number 5
If this doesn't resolve your issue, you can post a snapshot of your workspace and someone can take a look.
