|
* WARNING: this job assumes that there are not too many pages to process (dozens are fine, thousands are not) |
|
17
|
|
|
* as collecting URLs from all live pages will either eat up all available memory and / or stall |
|
18
|
|
|
* If your site has thousands of pages you need to consider a different static cache refresh solution |
|
19
|
|
|
* Ideally, the whole site re-cache would be segmented into smaller chunks and spread across different times of the day |

This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent.
Consider making the comparison explicit by using
empty(..)or! empty(...)instead.
