PHP and MYSQL Tutorials For Dynamic Websites - Variables
In this lesson, I have teach about the basic syntax of PHP in these PHP and MYSQL tutorials. Followings are the important things about variables:
1- Basic convention of PHP variables are:
1.1 - It should start with a dollar sign $
1.2 - It should start with either a letter or a underscore
like $_name & $name
1.3 - It is case sensitive.
like $name and $Name are different php variables.
2- We can assign a value to a php variable using assignment operator (=).
3- We can print the values of php variables using any of these two methods:
3.1 - echo the variable name directly like echo $variablename;
3.2 - echo the variable name within double quotations like echo
"Hello, $variablename".
Things to remembers / PHP Variables Tips:
Donot write the variable name to be printed in single quotations it will not work in php.
