使用php避免重複行

-1

我正在嘗試做一個dico檢查。因此，當用戶寫一個字時，代碼將找到第一個字母並從對應表中檢查。我把字典分成26個表格。代碼正在運行，但代碼太糟糕了，太多的重複。我知道有一些方法可以減少所有的代碼。那麼...有什麼建議嗎？使用php避免重複行

此代碼是不可讀。如果條件相差一個字母，則所有條件均爲 – Aerendir

。你爲什麼要複製一個字母的整個字符串？ –

開關'用戶輸入的單詞的第一個字母'，如果它是'A'，那麼cpu將會前往Adiki表，所有以'A'開始的單詞都被存儲。 –

<?php 
    $firstletter = strtolower($word[0]); //making it lowercase 
    if(ctype_alnum($firstletter)) { //checking if it's a letter and nothing else 
     $sql = "SELECT mot FROM {$firstletter}diki WHERE mot='$word'"; 
     if (mysql_num_rows(mysql_query($sql,$conn))>0) { 
      echo $f1.' est correct ! <br>'; 
     } 
     else { 
      echo $f2.' est incorrect !<br>'; 
      //what ever else you need here 
     } 
    } else { 
     echo('First character is not a letter.'); 
    } 
?>
