現象

打開頁面，PHP-CGI退出，Nginx錯誤日誌以下：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

緣由

打開其它頁面都沒問題，只有這個頁面有問題，應該是那個頁面的PHP代碼的問題。數組

經過排除法，肯定是下面紅色的代碼致使：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 {
}測試

常量BEYOND_WIDGET定義以下：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，這個問題在PHP 7下是沒有的，在PHP 5.6下出現。日誌

簡單總結一下，就是在PHP 5.6下，條件語句中訪問常量數組會出問題（未有全面測試，僅從本案例獲得結論，不必定準確）。server

解決

既然常量不行，那就把常量改爲變量：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 { }
