Php SQLi对用户输入文本的保护
我通常会进行手动sqli参数检查(即检查输入是否是有效的电子邮件) 虽然在这种情况下,我需要将用户消息放入我的数据库中 这是怎么回事 我试过这段代码,但是整个输入都被删除了Php SQLi对用户输入文本的保护,php,mysql,mysqli,Php,Mysql,Mysqli,我通常会进行手动sqli参数检查(即检查输入是否是有效的电子邮件) 虽然在这种情况下,我需要将用户消息放入我的数据库中 这是怎么回事 我试过这段代码,但是整个输入都被删除了 <?php $text = "Hello World"; echo "$text is now "; $text = stripslashes($text); $text = mysqli_real_escape_string($text); echo $text; ?> 谢谢你 防止PHP中的S
<?php

谢谢你 防止PHP中的SQL注入:
//Escaping characters
$db->real_escape_string('This is an unescaped "string"');
//There is an alias function that you can use which is shorter and less to type:
$db->escape_string('This is an unescape "string"');
您可以使用以下任何一种方式来实现此目的:
//Escaping characters
$db->real_escape_string('This is an unescaped "string"');
//There is an alias function that you can use which is shorter and less to type:
$db->escape_string('This is an unescape "string"');
mysqli\u real\u escape\u string
需要链接参数,这里没有链接参数,其余的我不明白你到底需要什么谢谢你的回答
