Question

我的php脚本从db（id，name，path，status，tags，date）获取数据，然后php扫描项目目录中的所有html，php，css和js文件，并将它们分类为4个数组。之后，它格式化输出。在sortFiles函数中，它检查是否有文件夹，如果它检测到文件夹，则调用相同的函数。它工作正常，但在第一个文件夹后，php不会跳回到第一个foreach循环然后完成...这是我的代码：

    function sortFiles($dir,$name){
        foreach ($dir as $file) {
            $tmp = explode(".", $file);
            if($tmp[1] === "html" || $tmp[1] === "css" || $tmp[1] === "js" || $tmp[1] === "php"){
                $tmpArray = array();
                $url = "http://www.nimmi.de/" . $GLOBALS["entry"][1] . "/" . $name . $file;
                //$GLOBALS["output"] .=  "NAME: " . $name;
                array_push($tmpArray,$name . $file);
                array_push($tmpArray,$url);
                switch ($tmp[1]) {
                    case 'html':
                        array_push($GLOBALS["html"],$tmpArray);
                        break;
                    case 'php':
                        array_push($GLOBALS["php"],$tmpArray);
                        break;
                    case 'css':
                        array_push($GLOBALS["css"],$tmpArray);
                        break;
                    case 'js':
                        array_push($GLOBALS["js"],$tmpArray);
                        break;

                    default:
                        die("Unknown filetype");
                        break;
                }
            }
            else if(strpos($file, '.') === false) {
                $GLOBALS["paths"] .= $file . "/";
                $GLOBALS["dirpath"] .= "/" . $file;
                $subdir = scandir($GLOBALS["dirpath"]);
                sortFiles($subdir,$GLOBALS["paths"]);
            }
        }
    }

有人知道这个问题吗？

解决方案（感谢Ryan Vincent）：

function sortFiles($dir,$name){//$dir --> directory to query, $name --> subfolder names
        foreach ($dir as $file) {//iterate through all files and sort them
            $tmp = explode(".", $file);//splitts the file string into the name and the extension
            if($tmp[1] === "html" || $tmp[1] === "css" || $tmp[1] === "js" || $tmp[1] === "php"){//checks the extension
                $tmpArray = array();//wrapper array
                $url = "../" . $GLOBALS["entry"][1] . "/" . $name . $file;//assemble the $url
                array_push($tmpArray,$name . $file);//push the $name into the wrapper array
                array_push($tmpArray,$url);//push the $url into the wrapper array
                //push the wrapper into the specific extension array
                switch ($tmp[1]) {
                    case 'html':
                        array_push($GLOBALS["html"],$tmpArray);
                        break;
                    case 'php':
                        array_push($GLOBALS["php"],$tmpArray);
                        break;
                    case 'css':
                        array_push($GLOBALS["css"],$tmpArray);
                        break;
                    case 'js':
                        array_push($GLOBALS["js"],$tmpArray);
                        break;

                    default:
                        die("Unknown filetype");
                        break;
                }
            }
            else if(strpos($file, '.') === false) {//checks the $file if it is an folder
                array_push($GLOBALS["dirpath"], "/" . $file);//adds the subfolder to the directory
                $pathstr = implode("", $GLOBALS["dirpath"]);//unite the array to a string
                $subdir = scandir($pathstr);//scans the directory
                $dirname = explode($GLOBALS["dirpath"][0], $pathstr);//get the subfolder path as string
                sortFiles($subdir,$dirname[1] . "/");//call this function again to sort all files in the subfolder
                array_pop($GLOBALS["dirpath"]);//removes the last directory
            }
        }
    }

尝试不使用此行

die("Unknown filetype");

这可能会破坏嵌套循环。

完成调用函数后，PHP不会返回旧函数
