In this code we say 1 is equal to 1 which is true so it will echo out “True”. 

Code for if_if else statement with operators and variables(Screenshot11) :-

Screenshot11

<?php
$text = 'Something';
if ($text=='Something')
{
echo 'TRUE.';
}
else
{
echo 'FALSE.';
}
?>

output (Screenshot12):-

In this example of code we are taking varibles “if statement” we aredefining variables and in different condition we are putting variables to compare and check which are true statements and which are false statements.

 Code for if_if else statement with operators and variables(Screenshot13) :-

Screenshot13

<?php
$text = 'Something';
if ($text=='Something else')
{
echo 'TRUE.';
}
else
{
echo 'FALSE.';
}
?>

output (Screenshot14):-

Screenshot14

In this example of “if statement” we declare variable $text as “Something” which will echo out “False”. Here, the “if statement” fulfills “Something else” and echoes “True” but in actual value is not “Something else” its “Something”.So this the basic structure of “if_else statement”.We can use if_else statement with keywords of if and else quiet easily! !
