All About Sql Injection..
How to defend yourself from SQL injection. All I know is that the attacker upload a PHP script from application form or any form from where you can upload a photo/video/ppt/etc . And then relocate the location of the PHP script by typing the name and location of the file in URL. The PHP script then run and may delete or stole your complete website . According to me the one solution is to put the uploading file in the folders like (62gHgU29hs) . So that the attacker cannot find the location but sometime our website itself start that PHP file so in that condition what can I do.?
