现象

打开页面，PHP-CGI退出，Nginx错误日志以下：html

2017/08/09 15:13:31 [error] 8140#19268: *1 WSARecv() failed (10054: An existing connection was forcibly closed by the remote host) while reading response header from upstream, client: 127.0.0.1, server: localhost, request: "GET /siteManager/template/templateEdit.html?id=1 HTTP/1.1", upstream: "fastcgi://127.0.0.1:9090", host: "localhost:8202", referrer: http://localhost:8202/siteManager/template/templateList.htmljson

缘由

打开其它页面都没问题，只有这个页面有问题，应该是那个页面的PHP代码的问题。数组

经过排除法，肯定是下面红色的代码致使：ide

if ($name == self::INPUT_HIDDEN) {
} elseif($name == self::INPUT_LARGE_FILE_UPLOAD) {
} elseif (isset(self::BEYOND_WIDGET[$name])) {
} elseif ($name == self::INPUT_RICH_EDIT) {
} else {
}测试

常量BEYOND_WIDGET定义以下：this

const INPUT_JSON = 'jsonEditor';
const INPUT_RICH_EDIT = 'richEdit';
const INPUT_HTML_CODE_EDITOR = 'htmlCodeEditor';
const BEYOND_WIDGET = [
self::INPUT_JSON => 'common\widgets\jsonEditor\JsonEditor',
self::INPUT_IMAGE => 'common\widgets\inputImage\InputImage',
self::INPUT_HTML_CODE_EDITOR => 'common\widgets\htmlCodeEditor\HtmlCodeEditor',
];spa

另外，这个问题在PHP 7下是没有的，在PHP 5.6下出现。日志

简单总结一下，就是在PHP 5.6下，条件语句中访问常量数组会出问题（未有全面测试，仅从本案例获得结论，不必定准确）。server

解决

既然常量不行，那就把常量改为变量：htm

const INPUT_JSON = 'jsonEditor';
const INPUT_RICH_EDIT = 'richEdit';
const INPUT_HTML_CODE_EDITOR = 'htmlCodeEditor';
private $BEYOND_WIDGET = [
self::INPUT_JSON => 'common\widgets\jsonEditor\JsonEditor',
self::INPUT_IMAGE => 'common\widgets\inputImage\InputImage',
self::INPUT_HTML_CODE_EDITOR => 'common\widgets\htmlCodeEditor\HtmlCodeEditor',
];

if ($name == self::INPUT_HIDDEN) {
} elseif($name == self::INPUT_LARGE_FILE_UPLOAD) {
} elseif (isset($this->BEYOND_WIDGET[$name])) {
} elseif ($name == self::INPUT_RICH_EDIT) {
} else { }
