PHP is partially case sensitive. The variable names are case-sensitive but function names are not. If you define the function name in lowercase and call them in uppercase, it will still work. User-defined functions are not case sensitive but the rest of the language is case-sensitive.

Some of the important characteristics of PHP variables include:

All variables in PHP are denoted with a leading dollar sign ($).
The value of a variable is the value of its most recent assignment.
Variables are assigned with the = operator, with the variable on the left-hand side and the expression to be evaluated on the right.
Variables can, but do not need, to be declared before assignment.
Variables in PHP do not have intrinsic types – a variable does not know in advance whether it will be used to store a number or a string of characters.
Variables used before they are assigned have default values.

The following rules are needed to be followed while naming a PHP variable:

    Variable names must begin with a letter or underscore character.
    A variable name can consist of numbers, letters, underscores but you cannot use characters like + , – , % , ( , ) . & , etc.

The final keyword in a method declaration indicates that the method cannot be overridden by subclasses. A class that is declared final cannot be subclassed. This is particularly useful when we are creating an immutable class like the String class.Properties cannot be declared final, only classes and methods may be declared as final.

PHP and Javascript cannot directly interact since PHP is a server side language and Javascript is a client-side language. However, we can exchange variables since PHP can generate Javascript code to be executed by the browser and it is possible to pass specific variables back to PHP via the URL.

Some of the popular frameworks in PHP are:

    CakePHP
    CodeIgniter
    Yii 2
    Symfony
    Zend Framework

PHP constructor and destructor are special type functions which are automatically called when a PHP class object is created and destroyed. The constructor is the most useful of the two because it allows you to send parameters along when creating a new object, which can then be used to initialize variables on the object.

The require() includes and evaluates a specific file, while require_once() does that only if it has not been included before. The require_once() statement can be used to include a php file in another one, when you may need to include the called file more than once. So, require_once() is recommended to use when you want to include a file where you have a lot of functions.

The set_time_limit(0) added at the beginning of a script sets to infinite the time of execution to not have the PHP error ‘maximum execution time exceeded.’ It is also possible to specify this in the php.ini file.

Some of the functions in PHP include:

    ereg() – The ereg() function searches a string specified by string for a string specified by pattern, returning true if the pattern is found, and false otherwise.
    ereg() – The ereg() function searches a string specified by string for a string specified by pattern, returning true if the pattern is found, and false otherwise.
    split() – The split() function will divide a string into various elements, the boundaries of each element based on the occurrence of pattern in string.
    preg_match() – The preg_match() function searches string for pattern, returning true if pattern exists, and false otherwise.
    preg_split() – The preg_split() function operates exactly like split(), except that regular expressions are accepted as input parameters for pattern.

The basic steps to create MySQL database using PHP are:

    Establish a connection to MySQL server from your PHP script.
    If the connection is successful, write a SQL query to create a database and store it in a string variable.
    Execute the query.

In PHP all functions starting with __ names are magical functions/methods. These methods, identified by a two underscore prefix (__), function as interceptors that are automatically called when certain conditions are met. PHP provides a number of ‘magic‘ methods that allow you to do some pretty neat tricks in object oriented programming

An exception that occurs at compile time is called a checked exception. This exception cannot be ignored and must be handled carefully. For example, if you use FileReader class to read data from the file and the file specified in class constructor does not exist, then a FileNotFoundException occurs and you will have to manage that exception. For the purpose, you will have to write the code in a try-catch block and handle the exception. On the other hand, an exception that occurs at runtime is called unchecked-exception.

PHP provides a library called cURL that may already be included in the installation of PHP by default. cURL stands for client URL, and it allows you to connect to a URL and retrieve information from that page such as the HTML content of the page, the HTTP headers and their associated data.

PHP callback are functions that may be called dynamically by PHP. They are used by native functions such as array_map, usort, preg_replace_callback, etc. A callback function is a function that you create yourself, then pass to another function as an argument. Once it has access to your callback function, the receiving function can then call it whenever it needs to.

They are both variables. But $message is a variable with a fixed name. $$message is a variable whose name is stored in $message. For example, if $message contains “var”, $$message is the same as $var.

Overloading is defining functions that have similar signatures, yet have different parameters. Overriding is only pertinent to derived classes, where the parent class has defined a method and the derived class wishes to override that method. In PHP, you can only overload methods using the magic method __call.

PHP is a programming language whereas ASP.NET is a programming framework. Websites developed by ASP.NET may use C#, but also other languages such as J#. ASP.NET is compiled whereas PHP is interpreted. ASP.NET is designed for windows machines, whereas PHP is platform free and typically runs on Linux servers.

• PHP echo output one or more string. It is a language construct not a function. So use of parentheses is not required. But if you want to pass more than one parameter to echo, use of parentheses is required. Whereas, PHP print output a string. It is a language construct not a function. So use of parentheses is not required with the argument list. Unlike echo, it always returns 1.
• Echo can output one or more string but print can only output one string and always returns 1.
• Echo is faster than print because it does not return any value.
