        比較基礎的php面試題及答案-填空題

          1.在PHP中,當前腳本的名稱(不包括路徑和查詢字符串)記錄在預定義變量__$_SERVER['PHP_SELF']__中;而鏈接到當前頁面的URL記錄在預定義變量__$_SERVER['HTTP_REFERER']__

          中

          2.執行程序段將輸出__0__。

          3.在HTTP 1.0中,狀態碼 401 的含義是____;如果返回“找不到文件”的提示,則可用 header 函數,其語句為____。

          4.數組函數 arsort 的作用是__對數組進行逆向排序并保持索引關系__;語句 error_reporting(2047)的作用是__報告所有錯誤和警告__。

          5.PEAR中的數據庫連接字符串格式是____。

          6.寫出一個正則表達式,過慮網頁上的所有JS/VBS腳本(即把scrīpt標記及其內容都去掉):preg_replace(“//si”, “newinfo”, $script);

          7.以Apache模塊的方式安裝PHP,在文件http.conf中首先要用語句____動態裝載PHP模塊,然后再用語句____使得Apache把所有擴展名為php的文件都作為PHP腳本處理。

          LoadModule php5_module “c:/php/php5apache2.dll” , AddType application/x-httpd-php .php,

          8.語句 include 和 require 都能把另外一個文件包含到當前文件中,它們的區別是____;為了避免多次包含同一文件,可以用語句__require_once||include_once__來代替它們。

          9.類的屬性可以序列化后保存到 session 中,從而以后可以恢復整個類,這要用到的函數是____。

          10.一個函數的參數不能是對變量的引用,除非在php.ini中把__allow_call_time_pass_reference boolean__設為on.

          11.SQL中LEFT JOIN的含義是__自然左外鏈接__。如果 tbl_user記錄了學生的姓名(name)和學號(ID),tbl_score記錄了學生(有的學生考試以后被開除了,沒有其記錄)的學號(ID)

          和考試成績(score)以及考試科目(subject),要想打印出各個學生姓名及對應的的各科總成績,則可以用SQL語句____。

          12.在PHP中,heredoc是一種特殊的字符串,它的結束標志必須____。

          答:

          function my_scandir($dir)

          {

          $files = array();

          if ( $handle = opendir($dir) ) {

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

          if ( $file != “..” && $file != “.” ) {

          if ( is_dir($dir . “/” . $file) ) {

          $files[$file] = scandir($dir . “/” . $file);

          }else {

          $files[] = $file;

          }

          }

          }

          closedir($handle);

          return $files;

          }

          }
