我在Production中的一个文件中收到以下错误，其中函数定义了两次。我尝试重新创建问题，进入另一个文件。
致命错误：无法重新声明foo（）（之前在声明中声明） /home/content/45/8989001/html/test/test.php:5）in 第10行/home/content/45/8989001/html/test/test.php
要取消此错误，建议您输入php.ini文件，但我无法将其作为共享托管进行访问。
或者，它建议在<?php ?>标签内输入现有的php文件。我做了以下更改。
error_reporting(0); // This is not working, still error is displayed
error_reporting(E_NONE); // This is not working, still error is displayed
ini_set('display_errors', 0); // This is not working, still error is displayed
我的完整代码，
<?php
function foo() {
return "foo";
}
function foo() {
return "foo";
}
// error_reporting(0); // This is not working, still error is displayed
// error_reporting(E_NONE); // This is not working, still error is displayed
ini_set ( 'display_errors', 0 ); // This is not working, still error is displayed
echo "hello";
?>
问题：如何在生产中抑制此错误，而是登录到某个文件。或者至少抑制错误？
注意：错误在prod中已修复，但是如何抑制它以避免用户下次在其他文件中看到错误
UPDATE1：
以下更改后，错误也是一样。
<?php
ini_set ( 'display_errors', 0 );
function foo() {
return "foo";
}
function foo() {
return "foo";
}
// error_reporting(0); // This is not working, still error is displayed
// error_reporting(E_NONE); // This is not working, still error is displayed
// ini_set ( 'display_errors', 0 ); // This is not working, still error is displayed
echo "hello";
?>
UPDATE2：
<?php
register_shutdown_function( "fatal_handler" );
function fatal_handler() {
echo "inside fatal_handler";
$errfile = "test";
$errstr = "shutdown this test";
$errno = E_CORE_ERROR;
$errline = 0;
$error = error_get_last();
echo $error;
if( $error !== NULL) {
$errno = $error["type"];
$errfile = $error["file"];
$errline = $error["line"];
$errstr = $error["message"];
$newline = "\r\n";
define ( 'senderName', 'Error' );
define ( 'senderEmail', 'admin@abc.com' );
$headers = "From: " . senderName . " <" . senderEmail . "\r\n";
$subject_admin = 'Error-Fix it';
$body_admin = "Dear Admin, $newline$newline An error occured $newline" . "error number : " . $errno . $newline . " error file : $errfile" . $newline . "error line :" . $errline . $newline . "error string : $errstr" . $newline;
$body_footer = " **** This is an an auto-generated mail. kindly do not reply to this mail. Thank You. ****" . $newline . $newline;
$body_admin = $body_admin . $newline . $newline . $newline . $body_footer;
$to_admin1 = 'mymail@gmail.com';
mail ( $to_admin1, $subject_admin, $body_admin, $headers );
//error_mail(format_error( $errno, $errstr, $errfile, $errline));
}
}
function foo() {
return "foo";
}
function foo() {
return "foo";
}
// error_reporting(0); // This is not working, still error is displayed
// error_reporting(E_NONE); // This is not working, still error is displayed
// ini_set ( 'display_errors', 0 ); // This is not working, still error is displayed
echo "hello";
?>
更新3
仍然得到同样的错误
<?php
register_shutdown_function ( "fatal_handler" );
function fatal_handler() {
echo 'YAY IT WORKED';
}
function foo() {
return "foo";
}
function foo() {
return "foo";
}
// error_reporting(0); // This is not working, still error is displayed
// error_reporting(E_NONE); // This is not working, still error is displayed
// ini_set ( 'display_errors', 0 ); // This is not working, still error is displayed
echo "hello";
?>
UPDATE4
<?php
//error_reporting(0);
function fatalErrorHandler() {
echo 'YAY IT WORKED';
}
# Registering shutdown function
register_shutdown_function('fatalErrorHandler');
// let force a Fatal error -- function does not exist
functiontest();
echo "hello";
?>
<!--
output:
Fatal error: Call to undefined function functiontest() in ...test2.php on line 12
YAY IT WORKED -->
<?php
error_reporting(0);
function fatalErrorHandler() {
echo 'YAY IT WORKED';
}
# Registering shutdown function
register_shutdown_function('fatalErrorHandler');
// let force a Fatal error -- function does not exist
functiontest();
echo "hello";
?>
<!-- output:
YAY IT WORKED -->
最终更新：
答案 0 :(得分：2)
如果我是你，我会打电话给我的主人并要求他们对我的phpini进行更改。他们可能会设置特殊的东西。
现在你永远不应该只是隐藏错误。您自己发送电子邮件并立即修复。您尝试压缩的错误是致命的，并且脚本将不再运行，因此隐藏它只会导致空白页面，用户stkill无法继续。
这是一个致命的错误，你无法从中恢复。在我看来，正确隐藏致命错误的方法是创建自己的错误处理函数。
你会用这样的东西来捕捉致命的错误。 http://php.net/manual/en/function.register-shutdown-function.php
该功能需要在每个页面上才能发生错误。我在我的db类中需要一个error.php，它位于每个页面上。
//This function gets called every time your script shutsdown
register_shutdown_function( "fatal_handler" );
function fatal_handler() {
$errfile = "unknown file";
$errstr = "shutdown";
$errno = E_CORE_ERROR;
$errline = 0;
$error = error_get_last();
if( $error !== NULL) {
$errno = $error["type"];
$errfile = $error["file"];
$errline = $error["line"];
$errstr = $error["message"];
//send error email
error_mail(format_error( $errno, $errstr, $errfile, $errline));
}
}
更新
** OP表示该函数未被调用。 **
上述情况应该有效。
这基本上是我在制作中使用的，它应该是有效的。
ON_SCREEN_ERRORS和SEND_ERROR_EMAIL是我自己的开发配置常量。
//Set error handler function (See function below)
set_error_handler("StandardErrorHandler");
/**
* Will take an error string and if ON_SCREEN_SQL_ERRORS is set to on, it will display the error on the screen with the SQL in a readable format and
* if SEND_SQL_ERROR_EMAILS is set to on, it will dendthe error email with the SQL in a readable format.
*
* PHP will pass these parameters automatically on error.
*
* @param string $errno The error type code.
* @param string $errstr The error string.
* @param string $errfile The file that the error occured in.
* @param string $errline The line number that the error occured.
*/
function StandardErrorHandler($errno, $errstr, $errfile, $errline) {
$Err = $errstr.'<br />'.GetErrorType($errno).'on line '.$errline.' in '.$errfile.'<br />';
if (ON_SCREEN_ERRORS===TRUE)
{
err($Err);
}
if ($errno =='256' and SEND_ERROR_EMAILS === TRUE)
{
$Path = "http://". $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];
// Custom error function
gfErrEmail($Err, $Path, 'SQL Error');
}
}
//Set the Fatal Error Handler function (See function below)
register_shutdown_function("FatalErrorHandler");
/**
* This function gets called on script shutdown, it will check if the last error is a fatal error. You cannot catch fatal errors,
* but using this function we will be notified about it and be able to fix it.
* If error is fatal, and if ON_SCREEN_FATAL_ERRORS is set to ON, this function will display the fatal error on the screen.
* If error is fatal, and if SEND_FATAL_ERROR_EMAILS is set to ON, this function will send error email.
*
