如何使用json从PHP页面获取两个或多个数组数据到javascript

Question

The code below is in EAddEmployeeAddAndOtherParts.php page:

$array1 = array("i am first array");
$array2 = array("i am second array");
echo json_encode($array1,$array2);

The code below is in the home.html page:

$(document).ready( function() {     
    $.ajax({
        type: 'POST',
        url: 'EAddEmployeeAddAndOtherParts.php',
        data: 'aa='+aa+'&f='+f,
        dataType: 'html',
        cache: false,
        success: function(result1,result2) {

alert(result1[0]);
alert(result2[0]);
        },          
    });
});

My question is: How can I get $array1 and $array2 data in my home.html page using JSON? My code above is not working.

Answer 1

The json_encode() only uses the first argument as the data, so wrap your two arrays into a single array:

echo json_encode(array('array1' => $array1, 'array2' => $array2));

In the ajax call, the response is the first argument, and because in the above, we used keys, we can directly reference result.array1 . So change to

dataType: 'json',
success: function(result) {
    alert(result.array1);
    alert(result.array2);
}, 

Also note, I changed the dataType to json . If you continue to use html as the dataType, then jQuery won't automatically parse the JSON for you.

Answer 2

header('Content-type:application/json');
echo json_encode(array($array1,$array2));
exit;
