Question

我需要对数组的每个部分进行查询现在我只是从爆炸中回应每个单词，但我需要为爆炸中的每个单词运行这样的查询：

(select * from words where word = $split_phrase[$i])

我想知道如何处理需要运行的单独查询。那我可以合并吗？以某种方式使用for循环？

我已查看其他帖子，但似乎没有任何内容直接解决此问题。

代码示例：我有2个表短语字

<?

/*  Table: phrases   */

$ID = 'ID'
$TARGET = 'TLP'

/*  Table: words   */

$ID_Split = 'ID';
$Word_Split = 'Word';
$WBW_Split = 'WBW';

?>


<table width="800">
<tr>
<th>Display Word</th>
</tr>

<?
/* I pass in a variable from another page which is inserted into the query */

    $phrase_query = mysql_query("SELECT * FROM phrases WHERE id=" . $_GET['id']);



/* Loop through the search results and explode the string on the column variable $Target */


    while($rows=mysql_fetch_assoc($phrase_query)) {

        $split_phrase = explode(" ", $rows[$TARGET]);



/* Loop through the string and list each word from the explode array / 
the html table in the echos is started outside the PHP tags */

    for($i = 0; $i < count($split_phrase); $i++)        {

        echo "<tr>";
        echo "<td>" .$split_phrase[$i] . "</td>";
        echo "</tr>";
                                                        }

?>

</table>

Answer 1

爆炸词

$words = explode(" ", $rows[$TARGET]);

转义并添加引号（php＆gt; = 5.3）

array_walk($words, function(&$word) {$word = '"' . mysql_real_escape_string($word) . '"';});

使用IN条件

运行查询

mysql_query('SELECT * FROM words WHERE word IN ('. join(', ', $words) .')');

你最好使用PDO或mysqli而不是mysql - 它已被弃用。

如何在新查询中使用爆炸数据？
