What if there is no backslash when php is entered into the library?

The backslash in the PHP data disappeared after it was inserted into the database

The reason is:

The backslash (\) needs to be escaped.

Include:

INSERT INTO `stu` VALUES ('lisi',' school\ class\ stu_num', '188 take 900')

It is not possible to insert the database directly like this.

So I used addcslashes ()

For example:

$deatil = addcslashes ($detail, "\"); INSERT INTO `stu` VALUES ("$name", "$detail", "$else")

I also thought of the magic_quotes_gpc function, so mention:

This feature is obsolete in PHP5.3.0 and removed in 5.4.0 (This feature has been DEPRECATED as of PHP5.3.0 and REMOVED as of PHP 5.4.0.). So there is no reason to use magic quotes anymore, because it is no longer part of PHP support. But it helps beginners write better (more secure) code before they know it. But when dealing with code, it is best to change your code rather than relying on the opening of magic quotation marks.
