PHP - 在同一個文件上多次運行相同的php函數

2014-07-04 74 views

我目前正在創建一個數據庫/表的列表排序系統，它將顯示當前用戶的喜好/不喜歡。用戶喜歡/不喜歡被取出，並由來自單獨文件的功能管理，該文件被稱爲displayRating()。我使用require_once在我的列表開始處調用它所在的單獨文件，然後開始工作。PHP - 在同一個文件上多次運行相同的php函數

我然後繼續前進，有我

foreach(...){ 
... 
displayRating($id); 
... 
}

但是我得到一個錯誤，這似乎是在告訴我，我不能調用一個函數在同一個頁面中多次。這是我確切的（未優化）代碼：

vote.php

<?php 
function displayRating($id){ 
    if(isset($id)){ 
     require_once('medoo.min.php'); 
     // Start up the D.B. Connection 
     $database = new medoo([ 
     // required 
     'database_type' => 'mysql', 
     'database_name' => '****', 
     'server' => 'localhost', 
     'username' => '****', 
     'password' => '****', 
     'charset' => 'utf8', 
     // driver_option for connection, read more from http://www.php.net/manual/en/pdo.setattribute.php 
     'option' => [ 
     PDO::ATTR_CASE => PDO::CASE_NATURAL 
     ]]); 
     // xf_user_field_value DB. Amount of ratings: 506c617965725f7261746573 Current Score: 706c617965725f726174696e67 
     $accountinfo = $database->select('xf_user_field_value', ['field_value'], ["user_id"=>$id]); 
     $vScore = $accountinfo[5]['field_value']; 
     // Processing Time 
     $phrase = '<div class="bc"><div data-hint="%1$s" class="hint--right vote %2$s"></div></div>'; 
     if($vScore == 0){ 
      printf($phrase, 'Neutral Score', 'v_equal'); 
      return; 
     } elseif ($vScore > 0){ 
      // Positive Here 
      switch($vScore){

下面是對於那些你們誰是熱衷於它的確切的錯誤 - 我混淆這裏的一些東西爲好，因爲我從現場工作安裝：

致命錯誤：不能重新聲明displayRating （）（以前在/ home聲明/ ** /的public_html/** /vote.php:2）在/ home/** /的public_html/** /vote.php上線68

兩個displayCodes.php和test.php的是需要vote.php，而後者是不是做一個require_once。將test.php切換到require_once（'vote.php'）;

它似乎這是經常發生的，因爲在你的test.php代碼中你包括了vote.php

require（'vote.php'）;

，你也都在test.php的

這裏的問題需要「displayCodes.php」是，你還叫「displayCodes.php」內vote.php因此函數在聲明兩次。嘗試在test.php中評論此行

require（'displayCodes.php'）;

這樣，你只是包括功能一次。

希望這有助於

我在vote.php裏面調用displayCodes.php？ – muffinjello

+0

是的，您正在使用require函數調用該文件。 – Antorni

嘗試刪除displayRating（）方法中的require_once('medoo.min.php');。你正在調用displayRating（）到一個循環，所以它可能包含medoo.min.php很多次。
