Question

我尝试将HTML写入文件，一切正常但我无法根据用户输入插入字符串 - 你能告诉我这里我做错了什么吗？

<?php 
if(isset($_POST['submit'])) {
$file = 'content.html';
$title = $_POST ['title'];
$content = '<li class="level-2"> <a class="level-2a" href="#">';
$content .= echo $title;
$content .= '
                      Lorem</a>
                       <div class="contentlevel2">
                        <span class="contentlilevel-2">
                            <!--ONEPAGECMS-START-';
$content .= echo $title;
$content .='


                            -->
                           Lorem Ipsum Doran....
                        <!--ONEPAGECMS-END-->
                  </span>
                </div>
                </li>';
file_put_contents($file, $content, FILE_APPEND | LOCK_EX);
}
?>

<div class="container">

    <div class="col-sm-6">
        <h1 class="text-center">Create new project</h1>
     <form action="project.php" method="post">
            <div class="form-group">
            <label for="title">Project title</label>
            <input type="text" name="title" class="form-control">
            </div>

            <input class="btn btn-primary" type="submit" name="submit" value="Create project">

        </form>


    </div>

Answer 1

$content .= echo $title;

应该只是

$content .= $title;

你创建一个字符串，回显输出到＆＃39;屏幕＆＃39;

另外：$title = $_POST ['title']; T和[之间没有空格（它会有点奇怪）

来自用户输入PHP的回声值
