Are string values 0 and 1 in an array the same as true / false?

[LPH]

This may seem like a silly question but something happened in the latest updates for WordPress and Redux Framework. For years, I've used $options['something'] == true and it stopped working. Now, the code must be $options['something'] == '1' in order to do as expected. A var_dump shows string instead of int and thus the question: are string values 0 and 1 in an array the same as true / false? I'm trying to figure out why the code is now failing when using true or false.

In my experience with another language 0 is false, anything else is true.

It turns out the use of strict comparisons is the issue.

“1” == true [ Correct. ]
“1” === true [ Incorrect. ]

Even though my question showed loose, the code was using strict.

Yes ... only after picking through the table and being very careful. As I described in my follow up post, the issue in my code was using strict instead of loose. This is in the table on that page, and how I figured it out. Regardless, others may run into the same challenge.
