* Generates a JavaScript script tag containing commands to store PHP array key-value pairs in local storage.
|
|
* This function is designed to translate PHP associative array data into JavaScript local storage items.
|
|
* It ensures that the array is associative and single-level before proceeding with the JavaScript code generation.
|
|
* This is used when dumping session data into local storage for use by the client script.
|
|
*
|
|
* @param array $phpArray The associative array whose data will be converted into JavaScript local storage setItem calls.
|
|
* @return string Returns a script tag with JavaScript code. If the input is not a valid single-level associative array,
|
|
* it returns a script with an error logged to the console.
