Unfortunately, directly passing an array as a parameter in a URL is not possible. URLs are designed to identify and locate resources on the internet, and they adhere to a specific structure. Typically, URL parameters are in the form of key-value pairs separated by an equal sign (=) and linked by an ampersand (&).
Even though it's not feasible to pass an array directly in a URL parameter, there are alternative approaches to achieve this:
1. Comma-Separated Values: Convert the array elements into a string separated by commas and then pass it as a parameter. For instance: ?array=element1,element2,element3.
2. Query String Parameters: Serialize the array into a query string format and then pass it as a parameter. For example: ?array[]=element1&array[]=element2&array[]=element3. In this method, the array is represented as multiple parameters with the same name, enclosed in square brackets [].
3. JSON Encoding: Transform the array into a JSON string, encode it for URLs, and pass it as a parameter. For example: ?array=%5B%22element1%22,%22element2%22,%22element3%22%5D. Here, %5B represents [ and %22 represents " in URL encoding.
Upon receiving the parameter value on the server-side, it will need to be parsed and converted back into an array based on the chosen encoding method.
It's essential to keep in mind that URLs have a maximum length limit, so if the array is extensive, you may encounter problems due to URL length restrictions. In such situations, using alternative methods like POST requests or encoding the array in a different format (e.g., Base64) may be a more suitable approach.
