Question

所以我想知道如何放置

<?php

$sql = "SELECT title, script_desc, banner, author, price FROM market";

$result = $conn->query($sql);
if ($result->num_rows > 0) {
    // output data of each row
    while ($row = $result->fetch_assoc()) {
        echo "  <div class=\"item  col-xs-4 col-lg-4\">
            <div class=\"thumbnail\">
                <img class=\"group list-group-image\" src=\"http://placehold.it/400x250/000/fff\" alt=\"\" />" . $row["banner"] . "/> <div class=\"caption\">
                    <h4 class=\"group inner list-group-item-heading\">" . $row["title"] . "</h4><div class=\"row\">
                    <div class=\"col-xs-12\">
                        <div class=\"col-xs-12 col-md-3\">
                            <p class=\"lead\">"
            . $row["price"] . "</div>
                        <div class=\"col-xs-12 col-md-5\">
                        0 reviews<br>
                        <span class=\"glyphicon glyphicon-star\"></span>
                        <span class=\"glyphicon glyphicon-star\"></span>
                        <span class=\"glyphicon glyphicon-star\"></span>
                        <span class=\"glyphicon glyphicon-star\"></span>
                        <span class=\"glyphicon glyphicon-star\"></span>

                        </div>
                        <div class=\"col-xs-12 col-md-4\">
                            <a class=\"btn btn-success\" href=\"scripts/example1\">" . $row["title"] . "</a>                        </div>
                        </div>
                    </div>
                </div>
            </div>
        </div>
    </div>
</div>
";
$conn->close();

 ?>

            echo "  <div class=\"item  col-xs-4 col-lg-4\">
            <div class=\"thumbnail\">
                <img class=\"group list-group-image\" src=\"http://placehold.it/400x250/000/fff\" alt=\"\" />" . $row["banner"] . "/>

因此将"src=\"http://placehold.it/400x250/000/fff\" "的来源更改为" src=\"$row["banner"] "

因此放置$row["Banner"]而不是"src=\"http://placehold.it/400x250/000/fff\"

所以基本上把行插入insinde听起来很笨拙的逗号很抱歉，不久前才开始php

更改此行：

function getArgs (): [string, number] {
  return ['hello world', 22]
}

function callFnWithArgs (callback: (...args: ReturnType<typeof getArgs>) => void) {
  callback(...getArgs())
}

callFnWithArgs(function (a, b) {
  // a is string, b is number
})

到

            <img class=\"group list-group-image\" src=\"http://placehold.it/400x250/000/fff\" alt=\"\" />" . $row["banner"] . "/> <div class=\"caption\">

这与将所有其他<img class=\"group list-group-image\" src=\"" . $row["banner"] . "\" alt=\"\" />" . $row["banner"] . "/> <div class=\"caption\">变量嵌入到输出中的方式相同。

顺便说一句，如果在字符串周围使用单引号，则不必在其中转义所有双引号。或者，您也可以在其中使用单引号，因为HTML允许在属性周围使用两种引号。

将行[“ tddaw”]放在逗号中
