Many developers find themselves needing to transform MySQL results into a portable JSON format, especially when building mobile applications. While generating an XML representation is possible, JSON offers a more lightweight alternative.
To achieve this conversion, start by creating an array from your mysqli query result. Subsequently, use the json_encode function to encode the array, which will produce a JSON string. Here's a code sample for your reference:
$mysqli = new mysqli('localhost','user','password','myDatabaseName'); $myArray = array(); $result = $mysqli->query("SELECT * FROM phase1"); while($row = $result->fetch_assoc()) { $myArray[] = $row; } echo json_encode($myArray);
This code generates JSON output resembling the following:
[ {"id":"31","name":"product_name1","price":"98"}, {"id":"30","name":"product_name2","price":"23"} ]
Alternatively, you can use fetch_row() instead of fetch_assoc() to obtain an output in this format:
[ ["31","product_name1","98"], ["30","product_name2","23"] ]
With this simple adjustment, you can now integrate your MySQL data seamlessly into your mobile applications, harnessing the flexibility of JSON.
