在 PHP 回显中运行 PHP 包含

Question

即使对我来说听起来也很奇怪，但基本上我需要的是在 echo 中包含一个 php 文件。不幸的是，我无法在 include 之前结束 echo 并在此之后继续它，因为所有这些都是 while 语句的一部分。

如果我像下面的代码那样做，在被视为注释的 html 中。

希望你能帮我弄清楚。

<?php
include('connect.php');
$nrcrt=1;
$sql="SELECT Cod, Nume, Categorie, Tumb, Tabel, Descriere FROM produse";
$sqlcateg="SELECT categ FROM categorii";
$resultcateg=$conn->query($sqlcateg);
$result=$conn->query($sql);

if($result->num_rows>0)
{
    while($row=$result->fetch_assoc())
        {   
            echo    '<tr>
                        <td>'.$nrcrt.'</td>
                        <td>'.$row['Cod'].'
                                <script type="text/javascript">
                                function editcod'.$nrcrt.'() {
                                var x = document.getElementById("fieldscod'.$nrcrt.'");
                                if (x.style.display === "none") {   
                                    x.style.display = "block";
                                } else {
                                    x.style.display = "none";
                                }
                                };
                                </script>
                                <br> <br> 
                                <button onclick="editcod'.$nrcrt.'()">Editare</button>

                                <br>
                                <input id="updatecod" type="submit" value="Update"></div>
                        </td>
                        <td>'.$row['Nume'].'
                                <script type="text/javascript">
                                function editnume'.$nrcrt.'() {
                                var x = document.getElementById("fieldsnume'.$nrcrt.'");
                                if (x.style.display === "none") {   
                                    x.style.display = "block";
                                } else {
                                    x.style.display = "none";
                                }
                                };
                                </script>
                                <br> <br>
                                <button onclick="editnume'.$nrcrt.'()">Editare</button>
                                <br>
                                <div id="fieldsnume'.$nrcrt.'" hidden><input type="text" id="fieldupdatenume" value="'.$row['Nume'].'">
                                <br>
                                <input id="updatenume" type="submit" value="Update"></div>
                        </td>

这就是问题所在。

Answer 1

您应该使用 php include 和依赖脚本创建一个完整的字符串文本作为字符串 init 然后eval 它。

例如：

 $str =    '
<div>
    <?php include("_include/php/readcateg.php");?>
    <?php  echo $var; ?>
</div>';
echo eval($str);
