*** Install XAMPP Apache+MariaDB+PHP+Perl)(Latest version 7.1.1)

:- XAMPP is the most popular PHP development environment

  • Install XAMPP his after open It and start Apache and MySQL go browser and search –
    https://loclalhost (here uses only htdocxs file your xampp file)

Variables
:- Prefix $
Start with a letter or an underscore
only letter, numbers and underscores
Case sensitive

Data types
:- String (ex- 12, 0, -34 etc.)
Integers (ex- 25.2654, 2.12, 41.54 etc.)
floats
Booleans (ex- true/false)
Arrays (ex- multiple values in one single variable)
Objects (ex- hold programming objects)
Null (ex- hold only one value- NULL)
Resource (ex- special variable that hold references to resources external to PHP)

  • some Data type class
    • $Output = ‘………’; (………= You can use any word which you shown in desktop )
    • $num1 = 4; ()
    • $num2 = 10;
    • $sum = #num1 + $num2;
    • $strings1 = ‘…….’;
    • $strings2 = ‘…….’;
    • $greeting = string1. ”. $strings.’!’;
    • $greeting2 = “$string1 $string2”;
    • $string3 = ‘They\’re Here”;
      :- define(‘GREETING’, ‘Hello Everyone’, true);
      :- echo greeting;
  • Array– basically variable that holds multiple values these are three types:-
    1) Indexed
    2) Associative
    3) Multi-dimensional

** 1)Indexed
some Indexed class
– $people = array(‘……..’, ‘………’, ‘……..’;
:- echo $people[3];

123456- $ids = array (23, 55, 12);:- echo $ids[2]; - $cars= ['honda', 'Toyota', 'Ford';]:- $cars[3]= 'Chevy';:- echo $ids[3];

** 2) Associative arrays
– $people = array(‘…….’=> 35, ‘……..’=> 32, ‘……..’ => 27);
:- $ids = [22 => ‘…….’ ];
:- echo $ [‘……’];

** 3) Multi Dimensional
$cars = array(
array(‘Honda’, 20, 10),
array (‘Toyota’, 30, 20),
array (‘Ford’, 23, 12),
);
echo $cars[1][2]

Some Important Rational Operators-

==  equal to    5==2            false
!=  not equal to    5!=2        true
=== identical   $a===$b         True if $a is equal to $b
                                and they are of the same
<>  not euqal   $a <> $b        true if $a is not euqal to 
                                $b, or they are not of the same 
<=> spaceship   $a <=> $b       it returns -1, 0 or 1 when $a is 
                                respectivelt less than, equal to, or 
                                 greater than $b
