& # 39;意外令牌# 39;使用JSON时.解析PHP中生成的数组

我试图AJAX JSON数组，但由于某种原因，当我使用JSON。Uncaught SyntaxError: Unexpected token

这是我的PHP:

$infoJson = array('info' => array());
while($row = mysqli_fetch_array($query))
{
    array_push($infoJson['info'],
    [
        'section' => $row['section'],
        'source' => $row['source'],
        'project' => $row['project'],
        'client' => $row['client'],
        'date' => $row['date'],
        'id' => $row['id']
    ]);
}
echo json_encode($infoJson);

这里是Javascript:

request = new XMLHttpRequest();
request.onreadystatechange = function()
{
    if(request.readyState == 4 && request.status == 200)
    {
        var response = request.responseText;
        response = JSON.parse(response);
    }
}
request.open('GET','http:edit.php?requestedArray=printArray',true);
request.send();

下面就是PHP要回显的内容:

{"info":[{"section":"printArray","source":"http:'/'/upload.wikimedia.org'/wikipedia'/commons'/thumb'/7'/7a'/SNES-Controller.jpg'/1280px-SNES-Controller.jpg","project":"SNES","client":"Nintendo","date":"1990","id":"7"},{"section":"printArray","source":"http:'/'/ecx.images-amazon.com'/images'/I'/81Q0l1t%2BaJL._SL1500_.jpg","project":"Playstation","client":"Sony","date":"1994","id":"8"},{"section":"printArray","source":"http:'/'/upload.wikimedia.org'/wikipedia'/commons'/e'/ed'/Xbox-360-S-Controller.png","project":"Xbox 360","client":"Microsoft","date":"2005","id":"9"}]}

如果不使用JSON。解析和console.log响应，我收到它作为一个字符串。
