Use jquery encoder to solve the problem caused by XSS Script Injection, jqueryxss
Symptom: the front-end receives a data (including html) tag in the background, automatically translates the tag into html page elements, and runs the script automatically, resulting in blocking of the front-end page.
The following code contains a large number of duplicated background data:

First of all, the content of this chapter is about WEB security, due to my knowledge limited this article may be wrong, if you have any questions can contact Uncle Wen (darrel.hsu@gmail.com ). Thank you very much for @ Sogl and @ Jianxin ~ The prevalence of WEB makes the network society richer, followed by security issues. If he is safe to accept user input and correctly display it, it is the pursuit of a vast number of WEB programs. One of them is to prevent

So the SQL statement has a similar wording: "SELECT * from CDR where src =". $userId; Change to $userId =mysql_real_escape_string ($userId)
All printed statements, such as Echo,print, should be filtered using htmlentities () before printing, which prevents XSS, note that the Chinese will write Htmlentities ($name, ent_noquotes,gb2312).
Here are two simple ways to prevent SQL injection

This article mainly introduces the PHP implementation of form submission data validation processing function, can achieve anti-SQL injection and XSS attacks, including PHP character processing, encoding conversion related operation skills, the need for friends can refer to the next
In this paper, we describe the validation and processing function of PHP to implement form submission data. Share to everyone
PHP implements the function of verifying and Processing Form submission data [preventing SQL injection and XSS attacks, etc.] And sqlxss
This example describes how PHP can verify and process data submitted by forms. We will share this with you for your reference. The details are as follows:
