我的 var_dump 停止工作，我该如何解决？

Question

当我在我的文件 php 中使用函数 var_dump 时，它不会像以前那样打印数组。我还没有接触过 wampserver 中的文件 php.ini，

函数 getFolder_recursive(&$array,$dir){

if(is_dir($dir)){

    $handle=opendir($dir);

    while (false!== ($entry=readdir($handle))) {

        if ($entry != "." && $entry != "..") {

            if (is_dir($dir.$entry)){

                $allFiles[]= "D: " . $dir . "/" . $entry;

               // echo "<a href='http://localhost/eclipse/access_log/logfiles.php?cartella=$c' class='btn btn-light>Cartella</a>";

            }

            else{

                $allFiles[]="F: " . $dir . "/" . $entry;

            }

        }

    }

    closedir($handle);

--> var_dump($allFiles);

}

return $array;     

}

这是它的打印方式：

array(7) { [0]=> string(22) "D: files/log_files//10" [1]=> string(21) "D: files/log_files//2" [2]=> string( 21) "D: files/log_files//3" [3]=> string(21) "D: files/log_files//4" [4]=> string(21) "D: files/log_files//6" [5]=> string(21) "D: files/log_files//7" [6]=> string(21) "D: files/log_files//

我希望 var_dump 打印我格式化的数组

只需添加<pre>标签function getFolder_recursive(&$array,$dir){&nbsp; &nbsp; if(is_dir($dir)){&nbsp; &nbsp; &nbsp; &nbsp; $handle=opendir($dir);&nbsp; &nbsp; &nbsp; &nbsp; while (false!== ($entry=readdir($handle))) {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if ($entry != "." && $entry != "..") {&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; if (is_dir($dir.$entry)){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $allFiles[]= "D: " . $dir . "/" . $entry;&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;// echo "<a href='http://localhost/eclipse/access_log/logfiles.php?cartella=$c' class='btn btn-light>Cartella</a>";&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; else{&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; $allFiles[]="F: " . $dir .
