Troubles with json_encode and their remedies
Frustratingly, when running `json_encode() over an array in PHP, if there are encoding errors with the array being converted, you'll typically see a return value of:
There was an error loading the requested resource
Vague, hard to reason about and confusing. In my case, I spent a day tussling with this issue, only to learn that the content contain malformed UTF-8 characters.
The best way to discover these sorts of errors with the json_encode() function, is to add the magic variable JSON_THROW_ON_ERROR as the second argument to the json_encode() function:
json_encode($yourArrayOfData, JSON_THROW_ON_ERROR);This will force PHP to throw whichever error it encounters, when trying to convert your data into a JSON object.
