Question

$data = array('Cardinal', 'Tom B.','tom@email.com');
$stmt = mysqli_prepare("INSERT INTO $table  (username,password,email) VALUES ($data)");

Answer 1

希望这会帮助你。在这里，我们在$data数组的字符串的开头和结尾附加单引号，然后使用,

将该数组包含在内

<?php

$data = array('Cardinal', 'Tom B.','tom@email.com');
//adding single quotes
$data=array_map(function($value){
    return $value="'$value'";
}, $data);
//imploding array with ,
$data=  implode(",", $data);
echo $query="INSERT INTO $table  (username,password,email) VALUES ($data)";
$stmt = mysqli_prepare($query);

输出： of echo $query;

INSERT INTO   (username,password,email) VALUES ('Cardinal','Tom B.','tom@email.com')

Answer 2

我认为最简单的方法就是：

$data = implode("','", ['Cardinal', 'Tom B.', 'tom@email.com']);
$stmt = mysqli_prepare(
    "INSERT INTO $table (username,password,email) VALUES ('$data')"
);

Answer 3

您只需使用

即可

"INSERT INTO $table (username,password,email) VALUES ('$data[0]','$data[1]','$data[2]')"

如何使用数组和内爆使这样的查询？
