What will be the output & how?

Question

<? Php
$var="I love php";
echo ++$var;
?>

Answer 1

error,
$ and var do not contain spaces 😁

if it's syntax error free, then output is already guven by Deepak

Answer 2

that was by mistake dude...take it easy sachin

Answer 3

Output is "I love phq". It seems that ++ operator increment the last character in the string.

I have tested with few letters, output was like this ----

'a' => 'b'
'b' => 'c',
'k' => 'l'
'z' => 'aa'

I am confused about the output for 'z'. Hope some expert will answer your question ( hopefully i will learn also :) )

Answer 4

I didn't think he placed the spaces intentionally, so I removed those spaces and tested 😴
