如何從PHP

Question

搜索的MySQL我有一個從用戶的查詢在mysql數據庫

<input type="text" name="query_textbox"><input type="submit" name="search_button"> 
<?php 
    if (isset($_GET['search_button'])) 
    { 
    $query = $_GET['query_textbox']; 
    $command = "SELECT * FROM `table` WHERE `ProteinName` LIKE '%$query%';"; 
    $result = mysql_query($command); 
    echo $result; 
    } 
?> 

搜索當我在文本框中把「人」，那麼它的工作原理。但是當我搜索「人類蛋白質」時，它顯示0個結果。 現在的問題是「如果我搜索包括像'人類蛋白質'這樣的空白的查詢，它應該顯示出'人類蛋白質'以及'人類'和'蛋白質'的結果。如何做？

Answer 1

你可以做這樣的事情：？？？您正在使用什麼引擎

$query = $_GET['query_textbox']; 

// explode the query by space (ie "human protein" => "human" + "protein") 
$keywords = preg_split("#\s+#", $query, -1, PREG_SPLIT_NO_EMPTY); 

// combine the keywords into a string (ie "human" + "protein" => "'%human%' OR '%protein%'") 
$condition = "'%" . implode("%' OR '%", $keywords) . "%'"; 

$command = "SELECT * FROM `table` WHERE `ProteinName` LIKE $condition;"; 

Answer 2

$query = $_GET['query_textbox']; 

// explode the query by space (ie "human protein" => "human" + "protein") 
$keywords = explode(" ", $query); 

foreach($keywords as $key => $value){ 
    $condition[] = `ProteinName` LIKE "'%".$value."%'" 
} 

$cond_str = implode(' OR ', $condition); 
$command = "SELECT * FROM `table` WHERE $cond_str;";
