PHP Interview Questions and answers

“heredoc” syntax can be used to declare complex strings,

What will out put the following code snippet?

<?php
$who = "questions";
echo <<<TEXT
So I said, "php interview $who"
TEXT;
?>

Answer – So I said, “php interview questions”

In general, the functionality of this heredoc syntax is similar to double quotes.

Using variable interpolation how we can print the following String?

“I am visiting the php interview questions website”.
The word “question” is inside a variable,
$a = ‘question’;

Answer is just,
echo “I am visiting the php interview {$a}s website”;
