[英]Trouble passing associative array from javascript to php and insert it into mysql database through prepared statements
[英]Javascript array from mysql database in php
var chartData = [{
"country": "Czech Republic",
"litres": 156.9
}, {
"country": "Ireland",
"litres": 131.1
}, {
"country": "Germany",
"litres": 115.8
}, {
"country": "Australia",
"litres": 109.9
}, {
"country": "Austria",
"litres": 108.3
}, {
"country": "UK",
"litres": 65
}, {
"country": "Belgium",
"litres": 50
}];
我想在php中使用mysql數據庫創建此數組,我該怎么做?
您可以從數據庫以數組格式獲取記錄,然后它將轉換為json對象。 試試下面的代碼
// fetch the record form mysql table using mysqli_fetch_assoc() and store it in $chartData
// then use json_decode() function used to convert the array into object format
$chartData[] = array("country"=> "Czech Republic", "litres"=> 156.9);
$chartData[] = array("country"=> "Czech Republic", "litres"=> 156.9);
$chartData[] = array("country"=> "Czech Republic", "litres"=> 156.9);
$chartData[] = array("country"=> "Czech Republic", "litres"=> 156.9);
$chartData[] = array("country"=> "Czech Republic", "litres"=> 156.9);
$chartData[] = array("country"=> "Czech Republic", "litres"=> 156.9);
echo '<pre>';
var_dump(json_encode($chartData));
我認為這將對您有所幫助.. :-)
