我有一組字符串，需要使用 str)replace 替換它們，因?yàn)槲覀儽闅v查詢，因?yàn)椴樵兂晒π枰鎿Q PHP 中的每個(gè)值。<?phpinclude_once("con.php");$db = new Da();$con = $db->con();$lclString = "{{ONE}} {{TWO}} {{THREE}} {{FOUR}} {{FIVE}} {{SIX}}"; $lclCount = 1; if(preg_match_all("/\{\{[^{}]+\}\}/", $lclString, $matches)) {    foreach ($matches[0] as $match) {        $lclQuery = "SELECT link, link_value FROM student WHERE link_value = '".$match."'";        $lclResult = $connString->query($lclQuery);        while($row = $lclResult->fetch(PDO::FETCH_ASSOC)) {            $lclNewValue = str_replace($match, $row['link'], $lclString);            }        }        echo json_encode($NewValue); } ?>這里只發(fā)生了第二次更換。
