Php For Beginners (Lesson 4b)

This lesson is in continuation with Php for Beginners lesson 4, so i will be continuing from where i left in lesson 4. Well in the last lesson, I was discussing php operators, and arithmetic operators were discussed in detail. In this lesson i will discuss Assignment operators and their usage in php.

Assignment Operators
Assignment operators are used to perform operations and assign values in variables. Basic assignment operators used in php are as follows:

= Operator

<?php
$a=5;
echo $a; // outputs 5
?>

+= Operator

<?php
$a=5;
$a+=6;
echo $a; // outputs 11
?>

$a+=6 is same as $a=$a+6.
-= Operator

<?php
$a=5;
$a-=4;
echo $a; // outputs 1
?>

$a-=6 is same as $a=$a-6.
*= Operator

<?php
$a=5;
$a*=6;
echo $a; // outputs 30
?>

$a*=6 is same as $a=$a*6.
/= Operator

<?php
$a=5;
$a/=2;
echo $a; // outputs 2.5
?>

$a/=6 is same as $a=$a/6.
.= Operator

<?php
$a=5;
$b=6;
$a.=$b;
echo $a; // outputs 56
?>

$a.=$b is same as $a=$a.$b.
%= Operator

<?php
$a=5;
$a%=2;
echo $a; // outputs 1
?>

$a%=6 is same as $a=$a%6.

This is all for assignment operators, feel free to comment and ask any questions that you may have.
