Question

我正在尝试执行以下操作。我在运行时有一个# # A fatal error has been detected by the Java Runtime Environment: # # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000007feedf911be, pid=4696, tid=4216 # # JRE version: Java(TM) SE Runtime Environment (8.0_77-b03) (build 1.8.0_77-b03) # Java VM: Java HotSpot(TM) 64-Bit Server VM (25.77-b03 mixed mode windows-amd64 compressed oops) # Problematic frame: # C [JNIShm.dll+0x11be] # # Failed to write core dump.

mariaDB

代码工作正常并返回以下行。

<?php

include '../db/mysql.php';

$line = mysqli_query($con,"SELECT * FROM `LineDetection`");
$circle = mysqli_query($con,"SELECT * FROM `CircleDetection`");
$lineArray=array();
$circleArray=array();
while($rowline=mysqli_fetch_assoc($line)){
    $lineArray[]=$rowline;
        }

echo json_encode($lineArray);
echo '<br>';

while($rowcircle=mysqli_fetch_assoc($circle)){
    $circleArray[]=$rowcircle;

}

echo json_encode($circleArray);

mysqli_close($con);

我的问题是现在我无法通过get阅读2个javascript对象。 1对象就好了。

[{"threshold":"10","deltaX":"20","minVal":"50","maxVal":"150"}][{"dp":"5","minDist":"20","cannyThreshold":"10","accThreshold":"112","minRadius":"100","maxRadius":"150"}]

谢谢道格。我用以下代码知道了。

echo '{"LineDetection":',json_encode($rowline),',"CircleDetection":', json_encode($rowcircle),"}";
