Case Study: array_key_exists WordPress Warning/Error – The first argument should be either a string or an integer in

Hi,

Problem Error:
Warning: array_key_exists() [function.array-key-exists]: The first argument should be either a string or an integer in /your-sitepath/wp-includes/category-template.php on line 176

Possible Solution:

- This problems stems from line 176 as stated above. The simple fix is to make sure the first argument is a string, to do this we will rap it in double quotes.

Change line 176 from:

if(array_key_exists($category, $categories))

To

if(array_key_exists(‘$category’, $categories))

Just add single quotes around the first $category variable which will fixed the issue.

Thanks,

Shane G.
