php$_post溢出,phpJquery.post（）返回数组堆栈内存溢出

您可以使用json_encode函数将任意数据转换为JSON。 假设您要返回一个字符串数组&＃xff0c;以下是使用json_encode的方法&＃xff1a;

include_once &＃39;../include/lib.php&＃39;;

$res &＃61; array(); // initialize variables

$sqlgr &＃61; sprintf("

SELECT ACT_ID

FROM PRIVILLAGE

WHERE MAINGR_ID&＃61;%d

",

$_POST[&＃39;gr_name&＃39;]

); // only select those columns that you need

// and do not trust user input

$resultgr &＃61; sql($sqlgr);

while($rowgr &＃61; mysql_fetch_array($resultgr)){

$res[] &＃61; $rowgr[&＃39;ACT_ID&＃39;];

}

echo json_encode($res); // use json_encode to convert the PHP array into a JSON object

// this will output something like [&＃39;foo&＃39;, &＃39;bar&＃39;, &＃39;blah&＃39;, &＃39;baz&＃39;] as a string

?>

在客户端&＃xff0c;您可以使用jQuery.post方法 &＃xff0c;如下所示&＃xff1a;

$("#group_name").change(function () {

$.post("selectedgr.php", {

gr_name: $(this).val()

}, function (data) {

// console.log(data);

// jQuery will convert the string "[&＃39;foo&＃39;, &＃39;bar&＃39;, &＃39;blah&＃39;, &＃39;baz&＃39;]" into a Javascript object

// (an array in this case) and pass as the first parameter

for(var i &＃61; 0; i

$("#" &＃43; data[i]).attr("checked", "checked");

}

}, "json");

});
