How to concatenate as in the code:
<?php
print ( "h".2);
It is actually giving error
PHP Parse error: syntax error, unexpected '.2' (T_DNUMBER) in /tmp/a.php on line 3
I've checked these Google results but unfortunately the solution does not work.
PHP doesn't like it when you have no space between the . and the number (this: "h".2 - no space).
Three ways to solve this:
print ("h" . 2);
Or
print ("h"."2");
Or
$n = 2;
print ("h".$n);
In the first, simply separate the number from the string concatenation operator with a space.
In the second, wrap the number to make it a string.
In the third, use a variable to hold the number.
<?php
print( "h" . "2");
Put number into " " and have a space between dot that is used concatenation
output
h2
the problem with your solution is that you used .2 without any space. For PHP . has meaning decimal point and not joining string with number (concat) look:
print( "h" . .2);
this will give
h0.2
first dot is treated as concatenation and second .2 as decimal point that translates to 0.2
