Php variables

variables means who can store the value and in further execution we can change the value means varying the value.

In c and C++ we normally declare variable :


datatype name of variable;

int c ;



:- Here datatype means whatever the value you will assign to c that is depend on the datatype means int can accept only integer values so you can not assign value with fraction part in c

ex c=9.7 that is wrong


but in php the syntax is

$name of your variable ;

for example : $a ;

$a="test";

or

$a = 8.9;

In the example above, you see that you do not have to tell PHP which data type the variable is.

PHP automatically converts the variable to the correct data type, depending on its value.

In a strongly typed programming language, you have to declare (define) the type and name of the variable before using it. thats why

PHP is a Loosely Typed Language.

Number Format In Javascript

Number.toFixed() :                                 Formats any number for "x" number of trailing decimals.

Check javascript is enable or disable

Hello there In our genreal practice of developing a webpage we use JAVASCRIPT. But do you know what will happen when in clients' browser javascript is disable and in your webpage you used it ?? Nothing will happen as per your expectation. It is good programming practice to check JAVASCRIPT is disabled or not . For example  <noscript>   <meta http-equiv = "refresh" content = "1;url=error.html" > </noscript>   This will redirect to an error page if script is disabled. Just replace error.html with the url of your error page. Or you also can do this   <noscript> <blink>Please enable javascript</blink> </noscript>
