Data types-PHP

PHP stores whole numbers in a platform-dependent range, either a 64-bit or 32-bit signed integer equivalent to the C-language long type. Unsigned integers are converted to signed values in certain situations; this behavior is different from other programming languages.Integer variables can be assigned using decimal (positive and negative), octal, and hexadecimal notations. Floating point numbers are also stored in a platform-specific range. They can be specified using floating point notation, or two forms of scientific notation.PHP has a native Boolean type that is similar to the native Boolean types in Java and C++.  Read more

Security

Vulnerabilities are caused mostly by not following best practice programming rules: technical security flaws of the language itself or of its core libraries are not frequent (23 in 2008, about 1% of the total).Recognizing that programmers make mistakes, some languages include taint checking to detect automatically the lack of input validation which induces many issues. Such a feature is being developed for PHP,but its inclusion in a release has been rejected several times in the past. Read more

User Authentication in PHP

 1) Basic authentication:
     We hard code the username and password combination in the login script itself. Suitable for simple application

2) User & password stored in database:
     A very common method. We store all the user name and password information in the database

3) User authentication with image verification:
    This is a more advance method of user authentication. We can prevent any automatic login by a robot ( script ) by using this method
