我有运行 Apache 并运行大量 php 脚本的亚马逊 ec2 实例。但是有一个 php 脚本无法运行或出现错误。
例如以下代码显示错误：
<?php
error_reporting(E_ALL); ini_set('display_errors', '1');
echo "Hello world";
owieufpowiejf
?>
Hello world Notice: Use of undefined constant owieufpowiejf - assumed 'owieufpowiejf' in /var/www/html/scripts/hello.php on line
但是这个脚本没有给出任何错误或正确运行代码，它只是显示白屏
<?php
error_reporting(E_ALL);
ini_set('display_errors', '1');
echo '<p>Hello World</p>';
$foo = new Foo;
$foo->init();
$foo->select();

// via parse_ini_file()... however, this will suffice

;error_log = php_errors.log我在文件中看到php.ini但找不到php_errors.log文件
我只是使用文本编辑器编写 php 代码并在服务器上进行测试。
知道为什么我可以看到任何东西，甚至是 hello world 输出吗？
