                1 請說明 PHP 中傳值與傳引用的區別。什么時候傳值什么時候傳引用? ~~~ 答: 傳值只是把某一個變量的值傳給了另一個變量,而引用則說明兩者指向了同一個地方。 ~~~ 2 在PHP中error_reporting這個函數有什么作用? ~~~ 答: The error_reporting() function sets the error_reporting directive at runtime. PHP has many levels of errors, using this function sets that level for the duration (runtime) of your script. ~~~ 3 請用正則表達式(Regular Expression)寫一個函數驗證電子郵件的格式是否正確。 答: ~~~ <?php if(isset($_POST['action']) && $_POST['action']=='submitted') { ????$email=$_POST['email']; ????if(!preg_match("/^(?:w+.?)*w+@(?:w+.?)*w+$/",$email)) ???? { ????????echo "電子郵件檢測失敗"; ???? } ????else ???? { ????????echo "電子郵件檢測成功"; ???? } } else { ?> <html> <head><title>EMAIL檢測</title> <script type="text/javascript"> ????function checkEmail(sText) ???? { ????????var reg=/^(?:w+.?)*w+@(?:w+.?)*w+$/; ????????var email=document.getElementById(sText).value; ????????if(!reg.test(email)) ???????? { ???????????? alert("電子郵件檢測失敗"); ???????? } ????????else ???????? { ???????????? alert("電子郵件格式正確"); ???????? } ???? } </script> </head> <body> <form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="POST"> 電子郵件:<input type="text" id="email" name="email" /><br /> <input type="hidden" name="action" value="submitted" /> <input type="button" name="button" value="客戶端檢測" onclick="checkEmail('email')" /> <input type="submit" name="submit" value="服務器端檢測" /> </form> </body> </html> <?php } ?> ~~~ 4 簡述如何得到當前執行腳本路徑,包括所得到參數。 ~~~ <?php echo "http://".$_SERVER['SERVER_NAME'].$_SERVER['PHP_SELF']."?".$_SERVER['QUERY_STRING']; //echo "http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']; ?> ~~~ 5 有一個一維數組,里面存儲整形數據,請寫一個函數,將他們按從大到小的順序排列。要求執行效率高。并說明如何改善執行效率。(該函數必須自己實現,不能使用php函數) ? ~~~ <?php function BubbleSort(&$arr) { ????$cnt=count($arr); ????$flag=1; ????for($i=0;$i<$cnt;$i++) ???? { ????????if($flag==0) ???????? { ????????????return; ???????? } ????????$flag=0; ????????for($j=0;$j<$cnt-$i-1;$j++) ???????? { ????????????if($arr[$j]>$arr[$j+1]) ???????????? { ????????????????$tmp=$arr[$j]; ????????????????$arr[$j]=$arr[$j+1]; ????????????????$arr[$j+1]=$tmp; ????????????????$flag=1; ???????????? } ???????? } ???? } } $test=array(1,3,6,8,2,7); BubbleSort($test); var_dump($test); ?> ~~~ ? 6 請舉例說明在你的開發過程中用什么方法來加快頁面的加載速度 ~~~ 答:要用到服務器資源時才打開,及時關閉服務器資源,數據庫添加索引,頁面可生成靜態,圖片等大文件單獨服務器。使用代碼優化工具啦 ~~~
