<?php
$text = 'Something';
if ($text=='Something')
{

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):-

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! !
