![]() ![]() ![]() Although we did not discuss how to fix all of the errors independently, I strongly believe you can take it from there as you have known what the error message. In this article, you have learned how to debug common json_encode() error and how to get them fixed. To fix it, I introduced `JSON_UNESCAPED_UNICODE`: echo( json_encode(, JSON_UNESCAPED_UNICODE) ) Conclusion This error happens if the result contains mixed encoding characters. Now, I see the error!: Malformed UTF-8 characters, possibly incorrectly encoded So I placed the code after the json_encode(…) function: echo json_last_error_msg() // Print out the error if any die() // halt the script It was not memory related.Īfter much trial and error, I decided to see what json_encode is complaining about if any. I went ahead to increase my memory limit but that did not help. But if I LIMIT the result to like 100 records, I get the JSON printed out but any record I fetch above 100 shows empty.Īt first, I thought it might be a memory issue (but 164 records is not that much □). The result was empty, nothing was printed out. In the last part of the code, I encode the array of courses to JSON then print out the result. In the code above, I’m fetching all the courses that are in the `courses` table that is about 164 records. Below is my complete code: $courses = $db = new mysqli(HOST, USERNAME, PASSWORD, DATABASE) if ($db->connect_error) echo( json_encode() ) die() I was working with a result which I fetched from the database that I converted to JSON. I encountered this error personally which prompted me to write this article. This is one of the common error you will face especially if you are fetching your data from a database. Fixing “Malformed UTF-8 characters, possibly incorrectly encoded” error Here is the list of errors you might encounter: If what was printed out is - “No errors”, then there is nothing wrong with the data. echo json_last_error_msg() // Print out the error if any die() // halt the script Add the below code in your code after the json_encode() function that you have. The first step in solving a problem is to first know what the problem really is.įirst, let’s see if there is any error from json_encode. In this article, I will discuss how you can fix a `json_encode` function that returns an empty result or throws an error. If there is any string padding surrounding your JSON string, jsondecode will return NULL. json_encode is a PHP function that converts an array to JSON format. If you are building a RESTful API in PHP, then you are most likely using the json_encode function. How I fixed PHP json_encode() returning empty result ![]()
