Question

测试php代码

<?php 
ini_set('error_reporting',E_ALL);
ini_set('display_errors','1');

echo 'test';
echo $x; //undeclared variable
echo 'test2';
?>

IIS6 / PHP5.3.6上的此代码输出＆＃34;测试通知：未定义的变量：x在第8行的测试中的x \ test.php＆＃34;

在IIS8.5 / PHP5.5.21（也运行plesk 12）上，它仅输出错误消息。

有没有办法让它输出所有含有内容的错误信息的内容？

我已经检查了所有设置（ini，iis，plesk），我认为无济于事，这是php 5.5中的设计更改，还是我错过了一个设置？

谢谢

P.S。这仅用于调试目的。

Answer 1

我找到了导致更改行为的配置设置。

这是FastCGI配置设置“标准错误模式”https://technet.microsoft.com/en-us/library/hh831548.aspx

在IIS管理器中，单击服务器节点并找到FastCGI设置（在IIS组中），您将看到一个或多个已定义的应用程序，单击php应用程序并单击操作菜单上的“编辑”以更改设置。（要查看与内容内联的错误，请选择'IgnoreAndReturn200'。（如technet文档中所述，此设置仅用于调试目的）

您可以参考：http://php.net/manual/en/function.set-error-handler.php

示例（来自php网站）：

<?php
// error handler function
function myErrorHandler($errno, $errstr, $errfile, $errline)
{
    if (!(error_reporting() & $errno)) {
        // This error code is not included in error_reporting
        return;
    }

    switch ($errno) {
    case E_USER_ERROR:
        echo "<b>My ERROR</b> [$errno] $errstr<br />\n";
        echo "  Fatal error on line $errline in file $errfile";
        echo ", PHP " . PHP_VERSION . " (" . PHP_OS . ")<br />\n";
        echo "Aborting...<br />\n";
        exit(1);
        break;

    case E_USER_WARNING:
        echo "<b>My WARNING</b> [$errno] $errstr<br />\n";
        break;

    case E_USER_NOTICE:
        echo "<b>My NOTICE</b> [$errno] $errstr<br />\n";
        break;

    default:
        echo "Unknown error type: [$errno] $errstr<br />\n";
        break;
    }

    /* Don't execute PHP internal error handler */
    return true;
}

// function to test the error handling
function scale_by_log($vect, $scale)
{
    if (!is_numeric($scale) || $scale <= 0) {
        trigger_error("log(x) for x <= 0 is undefined, you used: scale = $scale", E_USER_ERROR);
    }

    if (!is_array($vect)) {
        trigger_error("Incorrect input vector, array of values expected", E_USER_WARNING);
        return null;
    }

    $temp = array();
    foreach($vect as $pos => $value) {
        if (!is_numeric($value)) {
            trigger_error("Value at position $pos is not a number, using 0 (zero)", E_USER_NOTICE);
            $value = 0;
        }
        $temp[$pos] = log($scale) * $value;
    }

    return $temp;
}

// set to the user defined error handler
$old_error_handler = set_error_handler("myErrorHandler");

// trigger some errors, first define a mixed array with a non-numeric item
echo "vector a\n";
$a = array(2, 3, "foo", 5.5, 43.3, 21.11);
print_r($a);

// now generate second array
echo "----\nvector b - a notice (b = log(PI) * a)\n";
/* Value at position $pos is not a number, using 0 (zero) */
$b = scale_by_log($a, M_PI);
print_r($b);

// this is trouble, we pass a string instead of an array
echo "----\nvector c - a warning\n";
/* Incorrect input vector, array of values expected */
$c = scale_by_log("not array", 2.3);
var_dump($c); // NULL

// this is a critical error, log of zero or negative number is undefined
echo "----\nvector d - fatal error\n";
/* log(x) for x <= 0 is undefined, you used: scale = $scale" */
$d = scale_by_log($a, -2.5);
var_dump($d); // Never reached
?>

其中给出了一个示例输出：

vector a
Array
(
    [0] => 2
    [1] => 3
    [2] => foo
    [3] => 5.5
    [4] => 43.3
    [5] => 21.11
)
----
vector b - a notice (b = log(PI) * a)
<b>My NOTICE</b> [1024] Value at position 2 is not a number, using 0 (zero)<br />
Array
(
    [0] => 2.2894597716988
    [1] => 3.4341896575482
    [2] => 0
    [3] => 6.2960143721717
    [4] => 49.566804057279
    [5] => 24.165247890281
)
----
vector c - a warning
<b>My WARNING</b> [512] Incorrect input vector, array of values expected<br />
NULL
----
vector d - fatal error

  Fatal error on line 35 in file trigger_error.php, PHP 5.2.1 (FreeBSD)<br />

PHP 5.5显示与内容内联的错误
