計算與數據字的相同數據表中的

我有一句話，我想分成詞，然後在停用詞表中的數據進行檢查。我想統計相同數據的數量（總數）。但總計不會給我相同數據的總數。如何總結我需要的數據？感謝計算與數據字的相同數據表中的

$word ='temporal. the text mining in a evolutionary a theme patterns theme threads clustering'; 
$symbol = array(".", ",", "\\", "-", "\"", "(", ")", "<", ">", "?", ";", ":", "+", "%", "\r", "\t", "\0", "\x0B"); 
$cleanMeta = str_replace($symbol, " ", $word); 
$key  = strtolower($cleanMeta); 
$key = explode(" ", trim($key)); 

foreach($key as $word_key){ 
    $query = mysql_query ("SELECT COUNT(stoplist_word) AS total FROM tb_stopword WHERE stoplist_word = '$word_key'"); 
    while ($row = mysql_fetch_array($query)) { 
     $row1 = $row['total']; 
     echo $row1; 
    } 
}

你的得到，如果'的var_dump（$鍵）foreach'過嗎？ – GBD

@GBD'array（14）{[0] => string（8）「temporal」[1] => string（0）「」[2] => string（4）「text」[3] => string （6）「mining」[4] => string（2）「in」[5] => string（12）「evolutionary」[6] => string（1）「a」[7] => string（5））「theme」[8] => string（8）「patterns」[9] => string（0）「」[10] => string（5）「theme」[11] => string（7）「[12] => string（0）」「[13] => string（10）」clustering「}' –

對於每個關鍵字，你沒有得到'total' – GBD

考慮你已經清理輸入字符串，你不需要一個foreach與每一個字一個新的查詢。你可以這樣做：

$word ='temporal. the text mining in a evolutionary a theme patterns theme threads clustering'; 
$symbol = array(".", ",", "\\", "-", "\"", "(", ")", "<", ">", "?", ";", ":", "+", "%", "\r", "\t", "\0", "\x0B"); 
$cleanMeta = str_replace($symbol, " ", $word); 
$key  = trim(strtolower($cleanMeta)); 
$key  = str_replace("'","''",$key); 
$keys  = "'".str_replace(" ","', '", $key)."'"; 

$query = mysql_query ("SELECT COUNT(stoplist_word) AS total FROM tb_stopword WHERE stoplist_word IN ($keys)"); 
$row = mysql_fetch_array($query); 
$total = $row['total']; 

echo $total;

如果你真的想在foreach使用：

$total = 0; 
foreach($key as $word_key){ 
    $query = mysql_query ("SELECT COUNT(stoplist_word) AS total FROM tb_stopword WHERE stoplist_word = '$word_key'"); 
    while ($row = mysql_fetch_array($query)) { 
     $total += $row['total']; 
    } 
} 
echo $total;

您可能需要使用'mysqli'或'PDO'和事先準備好的聲明的所有單詞，變量綁定，以避免解析相同SQL一遍又一遍地在'foreach'解決方案中。 – Passerby

我只是用他自己的代碼讓他理解他的使用。更改爲mysqli，儘管強烈建議，但很可能意味着他必須更新他的所有頁面。 –
