我目前有一个简单的搜索引擎,它根据用户的输入搜索数据库中的列:
$search = $_GET['search'];
$terms = explode(" ", $search);
$sql = "SELECT * FROM people WHERE lname LIKE :search";
$q = $conn->prepare($sql) or die("failed!");
$q->bindValue(':search',"%".$search."%",PDO::PARAM_STR);
$q->execute();
if ($q){
//
do something
}
目前它正在搜索整个术语,例如“红色桌面”返回结果但“桌面红色”不返回任何内容
有什么想法吗?任何帮助非常感谢!
编辑:
我已将其改为此...
$search = $_GET['search'];
$terms = explode(" ", $search);
$sql = "SELECT * FROM people WHERE MATCH (lname,fname) AGAINST (:search IN BOOLEAN MODE)";
$q = $conn->prepare($sql) or die("failed!");
$q->bindValue(':search',"%".$search."%",PDO::PARAM_STR);
$q->execute();
现在似乎工作正常,如果有人能提出更好的解决方案,我会非常感激!

这可能不是最好的方法,但我认为这样的事情可能会起作用。我本想知道是否有更聪明的方法来做到这一点!
$search = $_GET['search'];
$terms = explode(" ", $search);
$sql = "SELECT * FROM people"
if(count($terms) > 0) {
$sql .= " WHERE (lname LIKE '%:term_0%' OR fname LIKE '%:term_0%')";
for($i = 1; $i < count($terms); $i++)
$sql .= " AND (lname LIKE '%:term_" . $i . "%' OR fname LIKE '%:term_" . $i . "%')";
}
$q = $conn->prepare($sql) or die("failed!");
for($i = 0; $i < count($terms); $i++)
$q->bindValue(':term_' . $i, $terms[$i]);
$q->execute();
