php - 意外包括预期的T_STRING

Question

我似乎看不到此代码有任何错误
它在PHP中，它试图通过mysqli_fetch_array()从MYSQLI数据库中获取用户“ yield ”，但是它总是伴随着这个错误
解析错误:语法错误，意外的'include'(T_INCLUDE)，第9行的test.php中的预期标识符(T_STRING)

<?php
session_start();
include "mysqli_config.php";
$username = $_SESSION['username'];
    $getuserearnings = "SELECT * FROM users WHERE username = '$username'";
    $user = $mysqli->query($getuserearnings);
            $userearnings= mysqli_fetch_array($user);
            $test= $userearnings['earnings'];
echo " This is your earnings "$test" Amount";
?>

Answer 1

您只需看语法高亮就可以看到错误。您没有在字符串中转义"。

echo " This is your earnings \"$test\" Amount";
