Is concatenation not needed in php?

Question

I'm new to php. I usually code in c#.

Answer 1

@Shaina, yes it's correct. It's called "string interpolation": https://en.wikipedia.org/wiki/String_interpolation
Notice that you must use double quotation mark in this case.

Answer 2

Thanks. I'll check out the link

Answer 3

Yes I know that. Sorry 🙈 I forgot to add the code I wanted to discuss.

The code is:
<?php
$myArray[0]= "John";
$myArray[1]= "<strong>PHP</strong>"
$myArray[2]= 21;

echo "$myArray[0] is $myArray[2] and knows $myArray[1]

//Outputs "John is 21 and knows PHP"
?>

This was the code in one of the lessons. I wanted to know if it is correct?

Answer 4

Thank you

Answer 5

yes you can use directly or concatenating:

echo "$myarr[0] is $myarr[2] and knows $myarr[1]"."<br>";
echo $myarr[0] . "is" . $myarr[2] . "and knkows " . $myarr[1];

both are giving same result.

Answer 6

the concatenation in php use dot (.) instead of +
