我有一个控制器动作如下：
public function actionTest()
{
set_time_limit(1);
register_shutdown_function(function()
{
var_dump('shutdown');
});
while(true){} //infinite loop
}
我仍然得到致命错误“超过1秒的最长执行时间”
如果我没有睡眠或超过执行时间，则调用关闭功能。 根据{{3}}和互联网上的几个例子，即使超出执行时间，也应该调用关闭。
我应该如何处理执行时错误？
答案 0 :(得分：0)
我敢打赌PHP在运行你的关机功能之前会抛出一个致命的错误。类似于＆＃34;致命错误：超出最大执行时间＆＃34;。 Yii的error handler捕获所有PHP错误，显示错误消息并在PHP有机会运行您的函数之前死亡。这样你的功能永远不会被执行。
这个问题有几种解决方案。首先，您可以通过将此行添加到import javax.swing.*;
import java.awt.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import static javax.swing.JOptionPane.showMessageDialog;
public class NewJFrame extends javax.swing.JFrame {
int selsalad=0;//count of the selected checkbox this cant go more than 2
String selectedsalad[]=new String[2];
// Variables declaration - do not modify
private javax.swing.JPanel jPanel1;
public NewJFrame() {
initComponents();
Salad();
showMessageDialog(null, "uncomment promlemmethod to see the probelm after you try this one");
problemmehtod();
}
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new NewJFrame().setVisible(true);
}
});
}

jPanel1Layout.setHorizontalGroup(

jPanel1Layout.setVerticalGroup(

);
javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addComponent(jPanel1, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)

else

来完全禁用Yii对PHP错误的处理。
index.php其次，您可以尝试使用error_reporting或display_errors指令在php.ini中禁用错误消息。
第三，您可以使用try-catch块捕获PHP错误并捕获ErrorException类。只是抓住异常而不采取任何措施：
