PHP based apps can face the different types of attacks. I have noticed the different types of attacks:

XSS - Cross-site scripting is a vulnerability in php web applications, which attackers may exploit to steal users' information. You can configure Apache and write more secure PHP scripts (validating all user input) to avoid xss attacks.

SQL injection - It is a vulnerability in the database layer of an php application. When user input is incorrectly filtered any SQL statements can be executed by the application. You can configure Apache and write secure code (validating and escaping all user input) to avoid SQL injection attacks. A common practice in PHP is to escape parameters using the function called mysql_real_escape_string() before sending the SQL query.

File uploads - It allows your visitor to place files (upload files) on your server. This can result into various security problems such as delete your files, delete database, get user details and much more. You can disable file uploads using php or write secure code (like validating user input and only allow image file type such as png or gif).

Including local and remote files - An attacker can open files from remote server and execute any PHP code. This allows them to upload file, delete file and install backdoors. You can configure php to disable remote file execution.

eval() - Evaluate a string as PHP code. This is often used by an attacker to hide their code and tools on the server itself. You can configure php to disable eval().

Sea-surf Attack (Cross-site request forgery - CSRF) - This attack forces an end user to execute unwanted actions on a web application in which he/she is currently authenticated. A successful CSRF exploit can compromise end user data and operation in case of normal user. If the targeted end user is the administrator account, this can compromise the entire web application.

A 30-year-old Canadian woman someone come up with a social networking website only for females.

The site Luluvise.com bans males from joining, the Daily Mail reported.

It links though other networking websites LinkedIn and Facebook. Since its launching on Wednesday, it already has 1,000 users in 69 countries.

"Luluvise uses Facebook to make enrollment easier. We do not post to walls or make Luluvise information public anywhere or to other Facebook users," creator Alexandra Chong was quoted as saying.

More than 500 men submitted their emails to get access to the site, but instead received an email reading: "Hey Dude, you're a dude."

The daily, however, said it was comparatively easy for men to get around the ban. All they need to do is set up a fake Facebook profile as a woman, and make friends with themselves on that social network.
