php and plus sign spacing

[hisoka]

Plus sign is used in php for making white space. So

 

How to make php echo white space between two strings using plus sign . For example :

 

<?php

 

$string = "hello";

$string1= "world";

echo $string+$string1;

?>

 

I need a result as this

 

hello world

 

But how ?

The plus sign is to operate with numbers. If you want to join the strings together, use the concatenation operator, which is a dot.

 

You can concatenate a literal string with a space in it to add a space between the other strings.

echo $string1 . ' ' . $string2;

An alternative way is to use double-quoted strings:

echo "$string1 $string2";

thank you

Another way:-

 

echo $string1 , ' ' . $string2;

 

or

 

echo $string1 , ' ' . $string2; // put in one space

 

using this method you can make it as many spaces as you want eg

 

echo $string1 , '   ' . $string2; //this will put in 3 spaces

 

and

 

echo $string1 , '     ' . $string2; //will put in 5
