如何使用数组和内爆来使我的查询像这样？

Question

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

Answer 1

希望这对您有帮助。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

,

对该数组进行内爆

<?php

$data = array('Cardinal', 'Tom B.','[email protected]');
//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.','[email protected]')

Answer 2

我认为最简单的方法是这样的：

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

Answer 3

您可以简单地使用

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